Anthropometric data can be used to identify the physical dimensions of equipment, furniture, clothing and workstations. The use of poorly designed furniture that fails to fulfil the users' anthropometric dimensions, has a negative impact on human health. In this study, we measured some anthropometric dimensions of Iranian children from different ethnicities. A total of 12,731 Iranian primary school children aged 7-11 years were included in the study and their static anthropometric dimensions were measured. Descriptive statistics such as mean, standard deviation and key percentiles were calculated. All dimensions were compared among different ethnicities and different genders. This study showed significant differences in a set of 22 anthropometric dimensions with regard to gender, age and ethnicity. Turk boys and Arab girls were larger than their contemporaries in different ages. According to the results of this study, difference between genders and among different ethnicities should be taken into account by designers and manufacturers of school furniture. In this study, we measured 22 static anthropometric dimensions of 12,731 Iranian primary school children aged 7-11 years from different ethnicities. Descriptive statistics such as mean, standard deviation and key percentiles were measured for each dimension. This study showed significant differences in a set of 22 anthropometric dimensions in different genders, ages and ethnicities.

Older adults are remaining sexually active for longer periods of time, underscoring the need to assess sexual activity patterns in this group and identify differences by race/ethnicity, some of which may have implications for the development and implementation of sexual risk reduction interventions. Using data from the 2010 National Social Life, Health, and Aging Project, this study examined responses from 1,429 adults aged 60 years and older. Multinomial logistic regression compared sexual behaviors, health-related indicators, interactions with healthcare professionals, and HIV-related perceptions across participants' race/ethnicity. Approximately 81% of participants self-reported as non-Hispanic white, 10.59% as African American, and 8.05% as Hispanic. On average, participants were 69.9 years of age. In the previous year, 49.3% of participants engaged in sexual intercourse; only 3% used condoms. The majority of participants (83.1%) visited a physician at least twice in the previous year, 30.9% had discussed sex with a physician since turning 50, and 14.2% had been tested for HIV. Relative to non-Hispanic whites, African Americans were more likely to be divorced (OR=3.23, P<0.001) or widowed (OR=2.90, P<0.001); have more lifetime sexually transmitted infection (STI) diagnoses (OR=1.67, P=0.030); and have paid for sex (OR=2.83, P=0.002). Although African Americans had greater perceived risk for HIV infection (OR=1.66, P=0.046), they were less likely to have discussed sex with a physician since turning 50 (OR=0.45, P=0.009). Contextualized interventions to improve patient-provider communication and proactive screening behaviors in sexually-active and aging African Americans are needed.

Data on continuous monitoring of stroke risk among different age and ethnic groups are lacking. We aimed to investigate age and ethnic disparities in stroke incidence over time from an inner-city population-based stroke register. Trends in stroke incidence and before-stroke risk factors were investigated with the South London Stroke Register, a population-based register covering a multiethnic population of 357 308 inhabitants. Age-, ethnicity-, and sex-specific incidence rates with 95% confidence intervals were calculated, assuming a Poisson distribution and their trends over time tested by the Cochran-Armitage test. Four thousand two hundred forty-five patients with first-ever stroke were registered between 1995 and 2010. Total stroke incidence reduced by 39.5% during the 16-year period from 247 to 149.5 per 100 000 population (P<0.0001). Similar declines in stroke incidence were observed in men, women, white groups, and those aged>45 years, but not in those aged 15 to 44 years (12.6-10.1; P=0.2034) and black groups (310.1-267.5; P=0.3633). The mean age at stroke decreased significantly from 71.7 to 69.6 years (P=0.0001). The reduction in prevalence of before-stroke risk factors was mostly seen in white patients aged>55 years, whereas an increase in diabetes mellitus was observed in younger black patients aged 15 to 54 years. Total stroke incidence decreased during the 16-year time period. However, this was not seen in younger age groups and black groups. The advances in risk factor reduction observed in white groups aged>55 years failed to be transferred to younger age groups and black groups.

Hispanic ethnicity is associated with a reduced risk of fatal falls in the elderly despite lower socioeconomic standing. The factors responsible for this "Hispanic paradox" are unknown. We hypothesized that age and gender would modify this relationship and that the association would be accentuated in a community with prominent Hispanic culture. The number of fatal falls in a 3-year period in the United States (US) and in Miami-Dade County, Florida (MDC) were obtained through the CDC's WISQARS database and the Florida Office of Vital Statistics. US Census Bureau data were used to define the total at-risk populations by age group and gender. Age group- and gender-specific ratios of the risk of fatal fall in Hispanic to white non-Hispanic individuals were calculated. In the US and MDC, Hispanic ethnicity was associated with a reduced risk of fatal fall across all age and gender subgroups. In the US, the risk reduction associated with Hispanic ethnicity grew from 11% and 23% in 65- to 74-year-old men and women, respectively, to 43% for both men and women over 84-years-old. This relationship was stronger in MDC than nationally in five of the six age and gender subgroups examined. Older individuals, women, and residents of communities with prominent Hispanic culture have the greatest reduction in fatal fall risk associated with Hispanic ethnicity.

This study aims to evaluate the associations of early menopause (menopause occurring before age 45 years) and age at menopause with incident heart failure (HF) in postmenopausal women. We also explored the associations of early menopause and age at menopause with left ventricular (LV) measures of structure and function in postmenopausal women. We included 2,947 postmenopausal women, aged 45 to 84 years without known cardiovascular disease (2000-2002), from the Multi-Ethnic Study of Atherosclerosis. Cox proportional hazards models were used to examine the associations of early menopause and age at menopause with incident HF. In 2,123 postmenopausal women in whom cardiac magnetic resonance imaging was obtained at baseline, we explored the associations of early menopause and age at menopause with LV measures using multivariable linear regression. Across a median follow-up of 8.5 years, we observed 71 HF events. There were no significant interactions with ethnicity for incident HF (Pinteraction > 0.05). In adjusted analysis, early menopause was associated with an increased risk of incident HF (hazard ratio, 1.66; 95% CI, 1.01-2.73), whereas every 1-year increase in age at menopause was associated with a decreased risk of incident HF (hazard ratio, 0.96; 95% CI, 0.94-0.99). We observed significant interactions between early menopause and ethnicity for LV mass-to-volume ratio (LVMVR; Pinteraction = 0.02). In Chinese-American women, early menopause was associated with a higher LVMVR (+0.11; P = 0.0002), whereas every 1-year increase in age at menopause was associated with a lower LVMVR (-0.004; P = 0.04) at baseline. Older age at menopause is independently associated with a decreased risk of incident HF. Concentric LV remodeling, indicated by a higher LVMVR, is present in Chinese-American women who experienced early menopause at baseline.

Objective To evaluate associations of early menopause (menopause occurring before 45 years of age) and age at menopause with incident heart failure (HF) in post-menopausal women. We also explored associations of early, and age at menopause with left ventricular (LV) measures of structure and function in post-menopausal women. Methods We included 2947 post-menopausal women, aged 45-84 years, without known cardiovascular disease (2000-2002), from the Multi-Ethnic study of Atherosclerosis. Cox-Proportional hazards models were used to examine associations of early, and age at menopause with incident HF. In 2123 post-menopausal women in whom cardiac magnetic resonance imaging was obtained at baseline, we explored associations of early, and age at menopause with LV measures using multivariable linear regression. Results Over a median follow-up of 8.5 years, we observed 71 HF events. There were no significant interactions with ethnicity for incident HF (Pinteraction>0.05). In adjusted analysis, early menopause was associated with increased risk of incident HF [1.66 (1.01-2.73)], while each year increase in age at menopause was associated with decreased risk of incident HF [0.96 (0.94-0.99)]. We observed significant interactions between early menopause and ethnicity for LV mass to volume ratio (LVMVR), Pinteraction=0.02. In Chinese-American women, early menopause was associated with higher LVMVR (+0.11, p=0.0002), while each year increase in age at menopause was associated with lower LVMVR (−0.004, p=0.04) at baseline. Conclusion An older menopausal age is independently associated with decreased risk of incident HF. Concentric LV remodelling, indicated by a higher LVMVR was present in Chinese-American women with early menopause at baseline. PMID:24423934

The present study aimed to explore previously unreported ethnic differences in infant feeding practices during the introduction of solid foods, accounting for maternal and birth factors, and to determine whether these feeding patterns are associated with BMI at 3 years of age. An observational study using Poisson regression was carried out to investigate the relationship between ethnicity and infant feeding practices and linear regression was used to investigate the relationship between feeding practices and BMI at 3 years of age in a subsample of 1327 infants in Bradford. It was found that compared with White British mothers, mothers of Other ethnicities were less likely to replace breast milk with formula milk before introducing solid foods (adjusted relative risk (RR) - Pakistani: 0·76 (95 % CI 0·64, 0·91), Other South Asian: 0·58 (95 % CI 0·39, 0·86), and Other ethnicities: 0·50 (95 % CI 0·34, 0·73)). Pakistani and Other South Asian mothers were less likely to introduce solid foods early ( < 17 weeks) (adjusted RR - Pakistani: 0·92 (95 % CI 0·87, 0·96) and Other South Asian: 0·87 (95 % CI 0·81, 0·93)). Other South Asian mothers and mothers of Other ethnicities were more likely to continue breast-feeding after introducing solid foods (adjusted RR - 1·72 (95 % CI 1·29, 2·29) and 2·12 (95 % CI 1·60, 2·81), respectively). Pakistani and Other South Asian infants were more likely to be fed sweetened foods (adjusted RR - 1·18 (95 % CI 1·13, 1·23) and 1·19 (95 % CI 1·10, 1·28), respectively) and Pakistani infants were more likely to consume sweetened drinks (adjusted RR 1·72 (95 % CI 1·15, 2·57)). No association between infant feeding practices and BMI at 3 years was observed. Although ethnic differences in infant feeding practices were found, there was no association with BMI at 3 years of age. Interventions targeting infant feeding practices need to consider ethnicity to identify which populations are failing to follow

The home food environment is complex and has the potential to influence dietary habit development in young people. Several factors may influence the home food environment, including income and race/ethnicity. To examine the relationship of income and race/ethnicity with three home food environment factors (ie, food availability frequency, family meal patterns [frequency of family and home cooked meals], and family food expenditures). A cross-sectional analysis of the National Health and Nutrition Examination Survey (NHANES). A total of 5,096 youth aged 6 to 19 years from a nationally representative sample of US individuals participating in NHANES 2007-10. Prevalence of food availability frequency was assessed for the entire sample, race/ethnicity, poverty income ratio (PIR), and race/ethnicity stratified by PIR. Mean values of family meal patterns and food expenditures were calculated based on race/ethnicity, PIR, and race/ethnicity stratified by PIR using analysis of variance and least squares means. Tests of main effects were used to assess differences in food availability prevalence and mean values of family meal patterns and food expenditures. Non-Hispanic whites had the highest prevalence of salty snacks (51.1%±1.5%) and fat-free/low-fat milk (39.2%±1.7%) always available. High-income homes had the highest prevalence of fruits (75.4%±2.4%) and fat-free/low-fat milk (38.4%±2.1%) always available. Differences were found for prevalence of food availability when race/ethnicity was stratified by PIR. Non-Hispanic blacks had the lowest prevalence of fat-free/low-fat milk always available across PIR groups. Differences in mean levels of family meal patterns and food expenditures were found for race/ethnicity, PIR, and race/ethnicity stratified by PIR. Race/ethnicity and PIR appear to influence food availability, family meal patterns, and family food expenditures in homes of youth. Knowledge of factors that influence the home food environment could assist in

We linked census and health service data sets to address the shortage of information comparing maternal characteristics and pregnancy outcomes by ethnic group in Scotland. Retrospective cohort study linking the 2001 National Census for Scotland and hospital obstetric data (2001-08), comparing maternal age, smoking status, gestational age, caesarean section rates, birthweight, preterm birth and breastfeeding rates by ethnic group. In all, 144 344 women were identified as having had a first birth between 1 May 2001 and 30 April 2008. White Scottish mothers were younger [mean age 27.3 years; 95% confidence interval (CI): 27.3, 27.4] than other white groups and most non-white groups. They had the highest smoking rates (25.8%; CI: 25.5, 26.0) and the lowest rates of breastfeeding at 6-8 weeks (23.4%; CI: 23.1, 23.6), with most of the other groups being around 40%. Women from non-white minority ethnic groups in Scotland tended to have babies of lower birthweight (e.g. Pakistani mean birthweight-3105 g, white Scottish-3356 g), even after adjustment for gestational age, maternal age, education, smoking and housing tenure. This effect was more noticeable for women born in the UK. White English, Irish and other white babies tended to have higher birthweights. There was little variation between groups in caesarean section rates. Pregnant women from ethnic minority populations in Scotland have more favourable health behaviour than the white Scottish, although the non-white groups tend to have lower birthweight. Further exploration of the reasons for these differences has potential to benefit women from the majority population. © The Author 2014.

Background Early malnutrition is linked to poor cognition, but long-term effects have not been extensively examined and psychosocial confounds have not always been controlled. Objective To test the hypothesis that malnutrition at age 3 years will be associated with poorer cognitive ability at age 11 years independent of psychosocial confounds. Design A prospective, longitudinal study of a birth cohort of 1559 children originally assessed at age 3 years for malnutrition (low hemoglobin level, angular stomatitis, kwashiorkor, and sparse, thin hair) and followed up to age 11 years. Setting and Participants A community sample of 1559 children (51.4% boys and 48.6% girls) born between September 1, 1969, and August 31, 1970, in 2 towns in the island of Mauritius, with 68.7% Indians and 25.7% Creoles (African origin). Main Outcome Measures Verbal and spatial ability measured at ages 3 and 11 years and reading, scholastic ability, and neuropsychologic performance measured at age 11 years. Results Malnourished children had poorer cognition at both ages. Deficits were stable across time, applied to all sex and ethnic groups, and remained after controlling for multiple measures of psychosocial adversity. Children with 3 indicators of malnutrition had a 15.3-point deficit in IQ at age 11 years. Conclusions Malnutrition at age 3 years is associated with poor cognition at age 11 years independent of psychosocial adversity. Promoting early childhood nutrition could enhance long-term cognitive development and school performance, especially in children with multiple nutritional deficits. PMID:12796242

Type 2 diabetes mellitus (T2DM) is the most common form of diabetes. Risk factors for its development include older age, obesity, family history of diabetes, history of gestational diabetes, impaired glucose metabolism, physical inactivity, and race/ethnicity. The purpose of this study was to characterize T2DM burden, from a patient perspective, with respect to age and race/ethnicity. Adults aged ≥18 years with T2DM from a large, Internet-based, nationwide survey were retrospectively analyzed. Demographic and clinical characteristics (glycemic control, body mass index [BMI], comorbidities, and diabetes-related complications), hypoglycemic episodes, and medication adherence were used to assess diabetes burden. Degree of burden was compared across age (18-64, 65-74, and ≥75 years) and racial/ethnic (white, African American, Hispanic, Asian, and American Indian) groups. An apparent association was found between glycemic control and medication adherence. Hispanics had the lowest percentage of participants with a hemoglobin A1c (HbA1c) level <7.0% (24.4%) and the highest percentage of those not knowing their HbA1c levels (55.4%) but also had the poorest medication adherence among racial/ethnic groups. Conversely, American Indians and whites had the best glycemic control, HbA1c knowledge, and medication adherence. The 18- to 64-year age group had the poorest glycemic control (28.8%), the most with unknown HbA1c levels (46.3%), and the poorest medication adherence of the age groups. Mean BMIs were high (>30 mg/kg(2)) for all racial/ethnic groups other than the Asian group (28.9 mg/kg(2)). Approximately 71% of Asians were obese or overweight compared with ≥90% in the other racial/ethnic groups. Mean BMIs decreased with increasing age group (34.5, 32.6, and 29.8 kg/m(2) for the age groups of 18-64, 65-74, and ≥75 years, respectively). Regarding diabetes-related comorbidities, the Asian group had the lowest percentages of those with hypertension (39.1%) and

Current literature shows different findings on the contemporary trends of distant-stage prostate cancer incidence, in part, due to low study population coverage and wide age groupings. This study aimed to examine the stage-specific incidence rates and trends of prostate cancer by age (5-year grouping), race, and ethnicity using nationwide cancer registry data. Data on prostate cancer cases came from the 2004-2014 United States Cancer Statistics data set. We calculated stage-specific incidence and 95% confidence intervals by age (5-year age grouping), race, and ethnicity. To measure the changes in rates over time, we calculated annual percentage change (APC). We identified 2,137,054 incident prostate cancers diagnosed during 2004-2014, with an age-adjusted incidence rate of 453.8 per 100,000. Distant-stage prostate cancer incidence significantly decreased during 2004-2010 (APC = -1.2) and increased during 2010-2014 (APC = 3.3). Significant increases in distant prostate cancer incidence also occurred in men aged older than or equal to 50 years except men aged 65-74 and older than or equal to 85 years, in men with white race (APC = 3.9), and non-Hispanic ethnicity (APC = 3.5). Using data representing over 99% of U.S. population, we found that incidence rates of distant-stage prostate cancer significantly increased during 2010-2014 among men in certain ages, in white, and with non-Hispanic ethnicity.

The number of people surviving until old age has been increasing worldwide. Reduction in fertility and mortality have resulted in increasing survival of populations to later life. This study examines the mortality trends among the three main ethnic groups in Malaysia, namely; the Malays, Chinese and Indians for four important age groups (adolescents, adults, middle age and elderly) for both gender. Since the data on mortality rates in Malaysia is only available in age groups such as 1-5, 5-9, 10-14, 15-19 and so on, hence some distribution or interpolation method was essential to expand it to the individual ages. In the study, the Heligman and Pollard model will be used to expand the mortality rates from the age groups to the individual ages. It was found that decreasing trend in all age groups and ethnic groups. Female mortality is significantly lower than male mortality, and the difference may be increasing. Also the mortality rates for females are different than that for males in all ethnic groups, and the difference is generally increasing until it reaches its peak at the oldest age category. Due to the decreasing trend of mortality rates, the government needs to plan for health program to support more elderly people in the coming years.

This study examined the association between romanticism (operationalized as mean score on the Romantic Beliefs Scale) and age, sex, and ethnicity in a large community sample (N = 436). Age was negatively correlated with romanticism scores; as age increased, romanticism scores decreased. No sex differences were found; men and women had similar, moderate scores. Although ethnicity largely was unrelated to romanticism, Asian/Pacific Islander participants were significantly more romantic than were African-American participants.

Nearly 18 million Americans experience limitations due to their arthritis. Documented disparities according to racial/ethnic groups in the use of surgical interventions such as knee and hip arthroplasty are largely based on data from Medicare beneficiaries age 65 or older. Whether there are disparities among younger adults has not been previously addressed. This study assesses age-specific racial/ethnic differences in arthritis-related knee and hip surgeries. Longitudinal (1998-2004) Health and Retirement Study. National probability sample of US community-dwelling adults. A total of 2262 black, 1292 Hispanic, and 13,159 white adults age 51 and older. The outcome is self-reported 2-year use of arthritis-related hip or knee surgery. Independent variables are demographic (race/ethnicity, age, gender), health needs (arthritis, chronic diseases, obesity, physical activity, and functional limitations), and medical access (income, wealth, education, and health insurance). Longitudinal data methods using discrete survival analysis are used to validly account for repeated (biennial) observations over time. Analyses use person-weights, stratum, and sampling error codes to provide valid inferences to the US population. Black adults under the age of 65 years report similar age/gender adjusted rates of hip/knee arthritis surgeries [hazard ratio (HR) = 1.43, 95% confidence interval (CI) = 0.87-2.38] whereas older blacks (age 65+) have significantly lower rates (HR = 0.38, CI = 0.16-0.55) compared with whites. These relationships hold controlling for health and economic differences. Both under age 65 years (HR = 0.64, CI = 0.12-1.44) and older (age 65+) Hispanic adults (HR = 0.60, CI = 0.32-1.10) report lower utilization rates, although not statistically different than whites. A large portion of the Hispanic disparity is explained by economic differences. These national data document lower rates of arthritis-related hip/knee surgeries for older black versus white adults age 65 or

The population of older adults (aged 65 years and older) in the United States will become more racially and ethnically diverse in the next three decades. Additionally, the growth of the aging population will come with an expansion in the number of older drivers and an increased prevalence of chronic neurological conditions. A major gap in the aging literature is an almost exclusive focus on homogenous, non-Hispanic white samples of older adults. It is unclear if this extends to the driving literature. A systematic review of SCOPUS, PubMed, CINAHL Plus, and Web of Science examined articles on driving and racial/ethnic differences among older adults. Eighteen studies met inclusion criteria and their results indicate that racial and ethnic minorities face a greater risk for driving reduction, mobility restriction, and driving cessation. The majority of studies compared African Americans to non-Hispanic whites but only examined race as a covariate. Only four studies explicitly examined racial/ethnic differences. Future research in aging and driving research needs to be more inclusive and actively involve different racial/ethnic groups in study design and analysis.

Existing electrocardiographic (ECG) reference values were derived in middle-aged Caucasian adults. We aimed to assess the association of age, sex, body size and ethnicity on ECG parameters in a multi-ethnic Asian population. Resting 12-lead ECG and anthropometric measurements were performed in a community-based cohort of 3777 older Asians (age 64.7±9.1 years, 1467 men, 88.8% Chinese, 7.7% Malay, 3.5% Indian, body mass index [BMI] 24.0±3.9kg/m(2)). Men had longer PR interval, wider QRS, shorter QTc interval and taller SV3. In both sexes, older age was associated with longer PR interval, wider QRS, larger R aVL and more leftward QRS axis, while higher BMI was associated with longer PR interval, wider QRS, larger RaVL and more negative QRS axis. There were significant inter-ethnic differences in QRS duration among men, as well as in PR and QTc intervals among women (all adjusted p<0.05). Findings were similar in a healthy subset of 1158 adults (age 61.2±9.1 years, 365 men) without cardiovascular risk factors. These first community-based ECG data in multi-ethnic older Asians highlight the independent effects of age, sex, body size and ethnicity on ECG parameters.

The goal of this study was to estimate the incidence of Parkinson's disease by age, gender, and ethnicity. Newly diagnosed Parkinson's disease cases in 1994-1995 were identified among members of the Kaiser Permanente Medical Care Program of Northern California, a large health maintenance organization. Each case met modified standardized criteria/Hughes diagnostic criteria as applied by a movement disorder specialist. Incidence rates per 100,000 person-years were calculated using the Kaiser Permanente membership information as the denominator and adjusted for age and/or gender using the direct method of standardization. A total of 588 newly diagnosed (incident) cases of Parkinson's disease were identified, which gave an overall annualized age- and gender-adjusted incidence rate of 13.4 per 100,000 (95% confidence interval (CI): 11.4, 15.5). The incidence rapidly increased over the age of 60 years, with only 4% of the cases being under the age of 50 years. The rate for men (19.0 per 100,000, 95% CI: 16.1, 21.8) was 91% higher than that for women (9.9 per 100,000, 95% CI: 7.6, 12.2). The age- and gender-adjusted rate per 100,000 was highest among Hispanics (16.6, 95% CI: 12.0, 21.3), followed by non-Hispanic Whites (13.6, 95% CI: 11.5, 15.7), Asians (11.3, 95% CI: 7.2, 15.3), and Blacks (10.2, 95% CI: 6.4, 14.0). These data suggest that the incidence of Parkinson's disease varies by race/ethnicity.

In this study, we aimed to establish whether age-sex-specific percentiles of coronary artery calcium (CAC) predict cardiovascular outcomes better than the actual (absolute) CAC score. The presence and extent of CAC correlates with the overall magnitude of coronary atherosclerotic plaque burden and with the development of subsequent coronary events. MESA (Multi-Ethnic Study of Atherosclerosis) is a prospective cohort study of 6,814 asymptomatic participants followed for coronary heart disease (CHD) events including myocardial infarction, angina, resuscitated cardiac arrest, or CHD death. Time to incident CHD was modeled with Cox regression, and we compared models with percentiles based on age, sex, and/or race/ethnicity to categories commonly used (0, 1 to 100, 101 to 400, 400+ Agatston units). There were 163 (2.4%) incident CHD events (median follow-up 3.75 years). Expressing CAC in terms of age- and sex-specific percentiles had significantly lower area under the receiver-operating characteristic curve (AUC) than when using absolute scores (women: AUC 0.73 versus 0.76, p = 0.044; men: AUC 0.73 versus 0.77, p < 0.001). Akaike's information criterion indicated better model fit with the overall score. Both methods robustly predicted events (>90th percentile associated with a hazard ratio [HR] of 16.4, 95% confidence interval [CI]: 9.30 to 28.9, and score >400 associated with HR of 20.6, 95% CI: 11.8 to 36.0). Within groups based on age-, sex-, and race/ethnicity-specific percentiles there remains a clear trend of increasing risk across levels of the absolute CAC groups. In contrast, once absolute CAC category is fixed, there is no increasing trend across levels of age-, sex-, and race/ethnicity-specific categories. Patients with low absolute scores are low-risk, regardless of age-, sex-, and race/ethnicity-specific percentile rank. Persons with an absolute CAC score of >400 are high risk, regardless of percentile rank. Using absolute CAC in standard groups performed

We investigated whether individual items on the nine item William's Perceived Everyday Discrimination Scale (EDS) functioned differently by age (<45 vs ≥ 45) within five racial groups in the United States: Asians (n=2,017); Hispanics (n=2,688); Black Caribbeans (n=1,377); African Americans (n=3,434); and Whites (n=854). We used data from the 2001-2003 National Survey of American Lives and the 2001-2003 National Latino and Asian Studies. Multiple-indicator, multiple-cause models (MIMIC) were used to examine differential item functioning (DIF) on the EDS by age within each racial/ethnic group. Overall, Asian and Hispanic respondents reported less discrimination than Whites; on the other hand, African Americans and Black Caribbeans reported more discrimination than Whites. Regardless of race/ethnicity, the younger respondents (aged <45 years) reported less discrimination than the older respondents (aged ≥ 45 years). In terms of age by race/ethnicity, the results were mixed for 19 out of 45 tests of DIF (40%). No differences in item function were observed among Black Caribbeans. "Being called names or insulted" and others acting as "if they are afraid" of the respondents were the only two items that did not exhibit differential item functioning by age across all racial/ethnic groups. Overall, our findings suggest that the EDS scale should be used with caution in multi-age multi-racial/ethnic samples.

Ethnic differences in cognitive development in the first 7 years: does maternal generational status matter?

Differences in cognitive development have been observed across a variety of ethnic minority groups but relatively little is known about the persistence of these developmental inequalities over time or generations. A repeat cross-sectional analysis assessed cognitive ability scores of children aged 3, 5 and 7 years from the longitudinal UK Millennium Cohort Study (white UK born n=7630; Indian n=248; Pakistani n=328; Bangladeshi n=87; black Caribbean n=172; and black African n=136). Linear regression estimated ethnic differences in age normed scores at each time point. Multivariable logistic regression estimated within-group generational differences in test scores at each age adjusting stepwise for sociodemographic factors, maternal health behaviours, indicators of the home learning environment and parenting styles. The majority of ethnic minority groups scored lower than the white UK born reference group at 3 years with these differences narrowing incrementally at ages 5 and 7 years. However, the black Caribbean group scored significantly lower than the white UK born reference group throughout early childhood. At 3 years, Pakistani, black Caribbean and black African children with UK born mothers had significantly higher test scores than those with foreign born mothers after baseline adjustment for maternal age and child gender. Controlling for social, behavioural and parenting factors attenuated this generational advantage. By 7 years there were no significant generational differences in baseline models. Ethnic differences in cognitive development diminish throughout childhood for the majority of groups. Cumulative exposure to the UK environment may be associated with higher cognitive development scores. Published by the BMJ Publishing Group Limited.

Previous examinations of breast cancer and survival in Hawai'i's 5 major ethnic groups have found that Native Hawaiian women have the highest breast cancer mortality rates. Although ethnic disparities in survival are reduced when age and stage at diagnosis are controlled for statistically, prior studies could not explain ethnic variation in survival among women who were diagnosed at the same stage. We examined variations in breast tumor characteristics for a multiethnic sample of 4,583 women diagnosed in 1990-1997 by stage and age group and extended previous multivariate analyses by adding a new prognostic variable: estrogen receptor (ER) and progesterone receptor (PR) status. Logistic regression was used to examine the influence of age, stage, and hormone status on 5-year survival. With a few exceptions, greater proportions of Native Hawaiian women were diagnosed both in later stages of disease and at earlier ages compared to women of other ethnicities, and smaller proportions of Native Hawaiians survived 5 years post diagnosis in each stage and age group. Surprisingly, greater proportions of Native Hawaiian women in all age groups had ER/PR positive tumors, which is a prognostic indicator for better, not worse, survival. Native Hawaiian women had an increased risk of death and Japanese women had an increased chance of survival after controlling for age, stage, and ER/PR status. Future studies should examine other reasons for better survival of Japanese women and worse survival of Native Hawaiian women, including socioeconomic status, access to health insurance, adequacy of recommended screening frequency, co-morbid conditions, treatment appropriateness and compliance, and genetic markers of tumor aggressiveness.

Multiethnic Malaysia provides a unique case study of divergence in population aging of different sociocultural subgroups within a country. Malaysia represents 3 major ethnicities in Asia-the Malay, Chinese, and Indian. The 3 ethnic groups are at different stages of population aging, as they have undergone demographic transition at different pace amidst rapid social and economic changes. Between 1991 and 2010, the Malaysian population aged 60 and over has more than doubled from about 1 million to 2.2 million, and this is projected to rise to about 7 million or 17.6% of the projected population of 40 million by 2040. In 2010, the aging index ranged from 22.8% among the Bumiputera (Malays and other indigenous groups), to 31.4% among the Indians and 55.0% among the Chinese. Population aging provides great challenges for Malaysia's social and economic development. The increasing prevalence of noncommunicable diseases in older adults, coupled with the erosion of the traditional family support system has increased demands on health care services with an overwhelming need for multidisciplinary and specialized geriatric care. Following the adoption of the National Policy for the Elderly in 1995, issues of population aging have gained increasing attention, especially among researchers. There is an urgent need to increase public awareness, develop infrastructure, as well as support action oriented research that will directly translate to comprehensive and cohesive social strategies, policies, and legislation to protect not just the current older Malaysians but the future of all Malaysians. © The Author 2015.

QuickStats: Birth Rates Among Teens Aged 15-19 Years, by Race/Hispanic Ethnicity* - National Vital Statistics System, United States,(†) 2007 and 2015(§).

PubMed

2016-08-19

From 2007 to 2015, the birth rate for female teens aged 15-19 years declined 46%, from 41.5 to 22.3 births per 1,000, the lowest rate ever recorded for this population in the United States. In 2015, rates declined to record lows for all racial/ethnic populations, with declines ranging from 41% for non-Hispanic white teens to 54% for Hispanic teens. Despite the declines, teen birth rates by race/Hispanic ethnicity continued to reflect wide disparities, with rates ranging from 6.9 per 1,000 for Asian or Pacific Islander teens to 34.9 for Hispanic teens in 2015.

Age, Ethnicity, and Socioeconomic Factors Impacting Infant and Toddler Fall-Related Trauma.

2016-10-04

To characterize trauma-related falls in infants and toddlers aged 0 to 3 years over a 4-year period and develop a risk stratification model of causes of fall injuries. Data on falls of 0 to 3 year olds from 2009 to 2012 were identified from a Jerusalem tertiary hospital trauma registry (N = 422) and the National Trauma Registry of Israel (N = 4,131). Almost half of falls occurred during the first year of life, and 57% of the children were Jewish. The majority of the children lived in low socioeconomic environments, both in the Jewish (59.2%) and Arab (97.6%) samples. Most (74%) of the falls resulted in head injury. A classification and regression tree analysis indicated that falls from furniture were the leading cause of injury in 0 to 12 month olds (estimated probability of 37.9%), whereas slipping is the leading cause in 13 to 36 month olds (estimated probability of 38.4%). Age and ethnicity emerged as the leading predictors of the nature of a fall; Injury Severity Score and the child's sex were secondary. Compared with the national data, Jerusalem children had a higher incidence of falls from buildings (9.3%; 2.4%), a higher moderate-severe Injury Severity Score (>16), a higher incidence of traumatic brain injury, and a longer hospital length of stay (P < 0.001). The leading determinants of fall injuries in children below the age of 3 years are age, ethnicity, and low socioeconomic status. Future outreach community interventions should target these risk groups and be tailored to their defining characteristics.

Ischemic stroke accounts for 70% to 80% of all strokes, but intracerebral and subarachnoid hemorrhagic strokes have greater fatality. Age-standardized death rates from overall stroke are higher among men than women, but little is known about sex differences in stroke subtype mortality by race/ethnicity. We analyzed 1995 to 1998 national death certificate data to compare sex-specific age-standardized death rates (per 100 000) for ischemic stroke (n=507 256), intracerebral hemorrhagic stroke (n=98 709), and subarachnoid hemorrhagic stroke (n=27 334) among whites, blacks, American Indians/Alaska Natives, Asians/Pacific Islanders, and Hispanics. We calculated rate ratios and 95% CIs comparing women with men within age and racial/ethnic groups. Age-specific rates of ischemic and intracerebral hemorrhagic stroke deaths were lower for women than for men aged 25 to 44 and 45 to 64 years but were higher for ischemic stroke among older women, aged > or =65 years. Only among whites did women have higher age-standardized rates of ischemic stroke. Age-standardized death rates for intracerebral hemorrhagic stroke among women were lower than or similar to those among men in all racial/ethnic groups. Women had higher risk of death from subarachnoid hemorrhagic; this sex differential increased with age. The female-to-male mortality ratio differs for stroke subtypes by race/ethnicity and age. A primary public health effort should focus on increasing the awareness of stroke symptoms, particularly among people at high risk, to decrease delay in early detection and effective stroke treatment.

Slow afternoon cortisol decline may be a marker of aging. We hypothesize that lower socioeconomic status (SES) and African American race are associated with lower waking cortisol and slower afternoon decline. Six salivary cortisol samples, collected within a 24-hr period from 566 cohort participants aged 56-78 years, were examined in random-effects models. SES measures included socioeconomic vulnerability (household income and assets <500% of poverty) and education (≥college, some college, and ≤high school). African Americans were compared with all others. Adjusting for age and sex, intermediate, but not low, education was associated with approximately 17% lower average waking cortisol and 1% slower decline, compared with high education. Socioeconomic vulnerability was not associated with waking cortisol or linear decline. Accounting for African American race/ethnicity, socioeconomic vulnerability was associated with a 3% faster decline, and education was not associated with cortisol. African Americans had 26% lower average waking cortisol and 1% slower decline than others. African American race/ethnicity, but not lower SES, was associated with lower waking cortisol and slower afternoon decline in middle-aged and older adults. This pattern is likely a marker of earlier biological aging in vulnerable groups. Race/ethnicity may compete with SES as a measure of cumulative vulnerability.

To determine whether reproductive age, as indexed by a validated marker of ovarian reserve (antimüllerian hormone [AMH]), varies among women of different race/ethnic backgrounds. Cross-sectional study. Community-based sample. Multiethnic sample of 947 (277 white, 237 African American, 220 Latina, and 213 Chinese) healthy and regularly cycling premenopausal women, ages 25-45. None. AMH level. A multivariate model was fit examining race/ethnicity, covariates, nonlinear terms for age (age(2), age(3)), and body mass index (BMI(2), BMI(3)), and two-way interactions between race/ethnicity and each of the other predictor variables in relation to AMH. After backward elimination, significant effects included race/ethnicity (F = 8.45), age (F = 349.94), race/ethnicity-by-linear age interaction (F = 4.67), age(2) (F = 31.61), and BMI (F = 10.69). Inspection of the significant race/ethnicity-by-linear age interaction showed AMH levels were consistently lower among Latina women compared with white women across all ages, whereas AMH levels were lower among African American and Chinese women compared with the white women at younger and middle ages, respectively. The AMH levels were higher among African American compared with Latina and Chinese women at older ages. Although the results must be considered preliminary, the findings are twofold: African American women may have lower AMH levels at younger ages but experience less of a reduction in AMH with advancing age, and Latina and Chinese women compared with white women may have lower AMH levels, marking a lower ovarian reserve and a possibly increased risk for earlier menopause.

PURPOSE To determine the normal size and wall thickness of the ascending thoracic aorta (AA) and its relationship with cardiovascular risk factors in a large population-based study. MATERIALS AND METHODS The mean AA luminal diameter was measured in 3573 Multi-Ethnic Study of Atherosclerosis (MESA) participants (age: 45–84 years), using gradient echo phase contrast cine MRI. Multiple linear regression models were used to evaluate the associations between risk factors and AA diameter. The median and upper normal limit (95th percentile) was defined in a “healthy” subgroup as well as AA wall thickness. RESULTS The upper limits of body surface area indexed AA luminal diameter for age categories of 45–54, 55–64, 65–74, and 75–84 years are 21, 22, 22, and 28 mm/m2 in women and 20, 21, 22, 23 mm/m2 in men, respectively. The mean AA wall thickness was 2.8 mm. Age, gender and body surface area were major determinants of AA luminal diameter (~+1 mm/10 years; ~+1.9 mm in men than women; ~+1 mm/ 0.23 m2; p<0.001). The AA diameter in hypertensive subjects was +0.9 mm larger than in normotensives (p<0.001). CONCLUSION AA diameter increases gradually with aging for both genders, among all race/ethnicities. Normal value of AA diameter is provided. PMID:23681649

To assess seven-year time trends in energy balance-related behaviours in 14-year-old adolescents living in an urban area and to examine the influence of educational level and ethnicity on these time trends. Second grade students (mean age 13·6 years) filled in questionnaires about the energy balance-related behaviours of breakfast consumption, fruit and vegetable consumption, physical activity and screen-time behaviour from school years 2006-2007 to 2012-2013. Energy balance-related behaviours were dichotomized and logistic regression analyses were used to examine time trends in healthy energy balance-related behaviours, including interaction terms for educational level and ethnicity. Secondary schools in Amsterdam, the Netherlands. Per school year, 2185-3331 children participated. The total sample included 19 244 students of Dutch, Surinamese, Turkish and Moroccan ethnic background. A significant linear increase was found for positive screen-time behaviour (<2 h/d; OR per year=1·04; 95 % CI 1·03, 1·06). For daily vegetable consumption a non-linear negative trend was observed (school year 2012-2013 v. 2006-2007: OR=0·90; 95 % CI 0·80, 1·00). Time trends in screen time were significantly different across educational levels (P-interaction=0·002) and ethnic backgrounds (P<0·001), as were time trends in daily fruit consumption (P=0·017 and P=0·018, respectively) and, for ethnicity, trends in daily vegetable consumption (P<0·001). The increase in positive screen-time behaviour is a positive finding. However, discouraging screen time and promoting other healthy behaviours, more specifically daily fruit and vegetable consumption, remain important particularly among adolescents enrolled in pre-vocational education and of non-Dutch ethnic background.

Early malnutrition is linked to poor cognition, but long-term effects have not been extensively examined and psychosocial confounds have not always been controlled. To test the hypothesis that malnutrition at age 3 years will be associated with poorer cognitive ability at age 11 years independent of psychosocial confounds. A prospective, longitudinal study of a birth cohort of 1559 children originally assessed at age 3 years for malnutrition (low hemoglobin level, angular stomatitis, kwashiorkor, and sparse, thin hair) and followed up to age 11 years. A community sample of 1559 children (51.4% boys and 48.6% girls) born between September 1, 1969, and August 31, 1970, in 2 towns in the island of Mauritius, with 68.7% Indians and 25.7% Creoles (African origin). Verbal and spatial ability measured at ages 3 and 11 years and reading, scholastic ability, and neuropsychologic performance measured at age 11 years. Malnourished children had poorer cognition at both ages. Deficits were stable across time, applied to all sex and ethnic groups, and remained after controlling for multiple measures of psychosocial adversity. Children with 3 indicators of malnutrition had a 15.3-point deficit in IQ at age 11 years. Malnutrition at age 3 years is associated with poor cognition at age 11 years independent of psychosocial adversity. Promoting early childhood nutrition could enhance long-term cognitive development and school performance, especially in children with multiple nutritional deficits.

Although research has documented age differences in substance use, less is known about how prevalence of substance use disorders (SUDs) vary across age and differ by gender and race/ethnicity. Time-varying effect models (TVEMs) were estimated on data from the National Epidemiologic Survey of Alcohol and Related Conditions-III (NESARC III; N=36,309), a nationally representative survey of the adult population. The sample was 44% male; 53% White, 21% Black, 19% Hispanic/Latino, 6% other race/ethnicity. Prevalence of four SUDs (alcohol, tobacco, cannabis and opioid use disorders) were flexibly estimated across ages 18-90 by gender and race/ethnicity. Estimated SUD prevalences were generally higher for men compared to women at most ages until the 70s. However, disparities by race/ethnicity varied with age, such that for most SUDs, estimated prevalences were higher for White participants at younger ages and Black participants at older ages. Results suggest relatively constant disparities by gender across age, and a crossover effect for Black and White participants. Findings demonstrate that Black individuals in midlife may be an important target of intervention programs for some substances. Copyright © 2017 Elsevier B.V. All rights reserved.

Objectives To study the baseline PSA profile and determine the factors influencing the PSA levels within a multiethnic Asian setting. Materials and Methods We conducted a cross-sectional study of 1054 men with no clinical evidence of prostate cancer, prostate surgery or 5α-reductase inhibitor treatment of known prostate conditions. The serum PSA concentration of each subject was assayed. Potential factors associated with PSA level including age, ethnicity, height, weight, family history of prostate cancer, lower urinary tract voiding symptoms (LUTS), prostate volume and digital rectal examination (DRE) were evaluated using univariable and multivariable analysis. Results There were 38 men (3.6%) found to have a PSA level above 4 ng/ml and 1016 (96.4%) with a healthy PSA (≤4 ng/ml). The median PSA level of Malay, Chinese and Indian men was 1.00 ng/ml, 1.16 ng/ml and 0.83 ng/ml, respectively. Indians had a relatively lower median PSA level and prostate volume than Malays and Chinese, who shared a comparable median PSA value across all 10-years age groups. The PSA density was fairly similar amongst all ethnicities. Further analysis showed that ethnicity, weight and prostate volume were independent factors associated with age specific PSA level in the multivariable analysis (p<0.05). Conclusion These findings support the concept that the baseline PSA level varies between different ethnicities across all age groups. In addition to age and prostate volume, ethnicity may also need to be taken into account when investigating serum PSA concentrations in the multiethnic Asian population. PMID:25111507

It has been suggested that extrinsic skin ageing manifests differently in Caucasians versus East Asians. In particular, from previous studies it was concluded that Caucasians are more prone to develop wrinkles, whereas pigment spot formation is the hallmark of extrinsic skin ageing in East Asians. However, these assumptions are based on a very limited number of studies which did not include different East Asian populations. We here compare the manifestation of extrinsic skin ageing signs in German, Japanese and Chinese women by specifically elucidating the age and anatomical site dependence of any potential ethnic difference. In the present study, we assessed skin ageing in N=902 German, N=165 Japanese and N=1260 Chinese women ranging from 30 to 90 years by means of SCINEXA™. Linear regression analysis was used to test for ethnic differences and their age and site dependence adjusted for educational level, sun exposure, smoking and sun protection behaviours. Pigment spots and wrinkles on the face were present among all three ethnic groups and differences were influenced by age and anatomical sites independently of further influencing factors. Pigment spots on the forehead were most pronounced over the whole age range in Chinese and German women and least developed in Japanese. Pigment spots on cheeks were a typical extrinsic skin an ageing sign in the two East Asian populations in all age groups. However, in older German women they reach the same level as observed in the two East Asian populations. In contrast, pigment spots on arms and hands were significantly more pronounced in German women ≥45years of age. Wrinkles were not exclusively a skin an ageing sign of German women, but were also very pronounced in Chinese women on forehead, between the eyebrows and in the crow's feet area. These results corroborate the previous notion that the occurrence of pigments spots and wrinkles is different between Caucasians and East Asians. In addition, this study shows

To meet the needs of a diverse patient population, an adequate supply of red blood cells (RBCs) from ethnic/racial minority donors is essential. We previously described the 10-year changes in minority blood donation in the United States. This study describes donation patterns by donor status, age, and race/ethnicity. Data on the age and the number of unique black/African American, Hispanic/Latino, Asian, and white RBC donors were obtained from eight US blood collectors for 2006, 2009, 2012, and 2015. Donors self-identified their race/ethnicity. First-time (FT) and repeat (R) donors were analyzed separately. Overall, for both FT and R donor groups, whites constituted the majority of unique donors (FT 66.7% and R 82.7%) and also donated the greatest proportion of RBC units (FT 66.6% and R 83.8%). Donors less than 20 years old comprised the greatest proportion of FT donors for all racial/ethnic groups (39.2%) and had the highest mean number of RBC donations per donor (1.12) among FT donors. Conversely, R donors less than 20 years old had some of the lowest mean number of RBC donations per donor (1.55) among R donors, whereas R donors at least 60 years old had the highest mean (1.88). Year by year, the percentage of FT donors who were less than 20 years old increased for all race/ethnicities. For R donors, whites were more frequently older, while Hispanics/Latinos and Asians were younger. Greater efforts to convert FT donors less than 20 years into R donors should be undertaken to ensure the continued diversity of the blood supply. © 2017 AABB.

To describe the relationships of selected candidate genes to the prevalence of early age-related macular degeneration (AMD) in a cohort of whites, blacks, Hispanics, and Chinese Americans. Cross-sectional study. setting: Multicenter study. study population: A total of 2456 persons aged 45-84 years with genotype information and fundus photographs. procedures: Twelve of 2862 single nucleotide polymorphisms (SNPs) from 11 of 233 candidate genes for cardiovascular disease were selected for analysis based on screening with marginal unadjusted P value <.001 within 1 or more racial/ethnic groups. Logistic regression models tested for association in case-control samples. main outcome measure: Prevalence of early AMD. Early AMD was present in 4.0% of the cohort and varied from 2.4% in blacks to 6.0% in whites. The odds ratio increased from 2.3 for 1 to 10.0 for 4 risk alleles in a joint effect analysis of Age-Related Maculopathy Susceptibility 2 rs10490924 and Complement Factor H Y402H (P for trend = 4.2×10(-7)). Frequencies of each SNP varied among the racial/ethnic groups. Adjusting for age and other factors, few statistically significant associations of the 12 SNPs with AMD were consistent across all groups. In a multivariate model, most candidate genes did not attenuate the comparatively higher odds of AMD in whites. The higher frequency of risk alleles for several SNPs in Chinese Americans may partially explain their AMD frequency's approaching that of whites. The relationships of 11 candidate genes to early AMD varied among 4 racial/ethnic groups, and partially explained the observed variations in early AMD prevalence among them.

1995-03-01

In recent years a number of research projects have reported on the level of alcohol use by young people. The research to date, however, has tended to overlook the ethnic origins of the young people as a factor associated with the level of alcohol use. Against this background, this paper reports findings on the use of alcohol by 15-16-year-olds in Leicestershire with specific reference to ethnic group. A survey of over 1000 young people revealed significant differences between ethnic groups in terms of their attitudes to alcohol consumption and the frequency of alcohol consumption. As expected, South Asians tended to hold less favourable attitudes to drinking alcohol than their White counterparts and reported a far lower frequency of alcohol consumption. The extent of the divergence between the two ethnic groups is detailed, revealing a stark contrast between the groups at age 15-16 years. Attitudes to alcohol consumption and reported frequency of alcohol consumption were also analysed in relation to the religion of the respondents. This analysis was undertaken to see if there were differences within the broader ethnic groups which would be disguised by aggregating the results under the headings of 'South Asian' and 'White'. Within the South Asian group, some differences in attitudes to the consumption of alcohol were found between Hindus, Sikhs and Muslims, with the Muslims exhibiting particular sensitivity to their religion's proscription of drinking alcohol. Despite this, the reported level of drinking by the Hindus and Sikhs was not much greater than that of the Muslims. The three groups tended to have a similar frequency of alcohol consumption which was markedly lower than that reported by the White 15-16-year-olds. The findings from the DART research have certain substantive and certain methodological implications in relation to epidemiological studies of alcohol consumption. Substantively, the findings reinforce the need to include ethnic group as a key

Vitamin A deficiency (VAD) is the most common cause of childhood blindness in the developing world. It is estimated that by giving adequate vitamin A, in vitamin A deficient populations, child mortality from measles can be reduced by 50%, and mortality from diarrheal disease by 40%. Overall mortality in children 6-59 months of age can be reduced by 23%. This paper reported results from a study of vitamin A status and malnutrition of the minority ethnic group of Karen hill tribe children aged 1-6 years in the north of Thailand. All children aged 1-6 years (N = 158; 83 boys, 75 girls) from the three Karen villages (Mae Hae Tai, Mae Yot, Mae Raek) of Mae Chaem district in the north of Thailand were studied. The Karen is the largest mountain ethnic minority ("hill tribe") group in Thailand. All children were examined by a qualified medical doctor and were assessed for their vitamin A intakes using 24 hours dietary recall. Thai food composition table from Ministry of Health, Thailand were used as references. The results were compared with the Thai Recommended Dietary Allowances. Children aged 1-3 years and 4-6 years were separately analysed due to the differences in Thai Recommended Dietary Allowances between the two age groups. A whole blood of 300 microL was obtained by "fingerstick" for determination of serum vitamin A. Community or village's vitamin A status was assessed by using Simplified Dietary Assessment (SDA) method and Helen Keller International (HKI) food frequency method. Descriptive statistics were used to analyse the data. All families of the study boys and girls had income lower than the Thailand poverty line (US $ 1,000/year). On average, 63% of children from Mae Hae Tai village, 1.5% of children from Mae Yot village and none of children from Mae Raek village had serum vitamin A<0.7 micromol/L which indicated VAD. All boys and only girls from Mae Raek village consumed vitamin A more than the Thai RDA but girls from Mae Hae Tai village and Mae Yot

Objective: To understand and evaluate the prevalence of myopia and its trend in children and adolescents aged 7-18 years in Han ethnic group in China from 2005 to 2014, and provide evidence for the prevention of myopia. Methods: The data of 2005, 2010 and 2014 Chinese National Students Constitution and Health Surveys were collected. The children and adolescents with complete detection data of binoculus were selected as study subjects. The sample size of three studies were 233 108, 215 319 and 212 743, respectively. The method of curve fitting was used to simulate the myopia detection increase model and analyze the gender and area specific myopia detection increase trends and characteristics from 2005 to 2014. Results: The overall myopia detection rate increased gradually in the children and adolescents aged 7 to 18, which was 47.5 % in 2005, 55.5 % in 2010 and 57.1 % in 2014, respectively. The increase slowed in 2014. A"parabola" shape of myopia detection increase rate was observed. Myopia detection rate increased with age before puberty and decreased with age after puberty gradually. A"cross phenomenon" of myopia detection increase was observed in boys and girls between urban and rural areas. The increase of myopia detection was mainly in urban students before puberty and in rural students after puberty. The age of myopia prevalence peak has become earlier constantly in children and adolescents aged 7-18 years from 2005 to 2014, which was 13 years old in 2005, 12 years old in 2010 and 11 years old in 2014. The increase rate was about 7 % . During 2005-2014, the increase rate of myopia detection gradually increased in younger students and tended to zero in older students. Conclusion: The detection rate of myopia was still high in children and adolescents in China. The age of myopia prevalence peak has become earlier gradually.

To examine the patterns of myopigenic activity (high near work, low time outdoors) in children growing up in Sydney, Australia, by age, ethnicity and gender. The Sydney Adolescent Vascular and Eye Study (SAVES) re-examined children from the two age cohorts (6 and 12 years at baseline) from the Sydney Myopia Study (SMS). At 5-6 year follow-up, 863 in the younger cohort and 1196 in the older cohort had complete refraction data. Cycloplegic autorefraction (cyclopentolate 1%; Canon RK-F1) was measured at baseline and follow-up. Children who became myopic (≤-0.50 dioptres spherical equivalent refraction) were those classified as non-myopic at baseline and myopic at follow-up. A detailed questionnaire was administered to measure weekly activities, including time spent outdoors and near work at both baseline and follow-up examination. Overall, 128 (14.8%) children in the younger cohort and 210 (17.6%) in the older cohort became myopic. At follow-up, for both cohorts, children had significantly reduced the amount of time spent outdoors (younger cohort, p = 0.001, older cohort, p < 0.0001) and increased near work time (younger cohort, p < 0.0001, older cohort, p = 0.006). Children of East Asian ethnicity spent significantly less time outdoors by more than 7 h per week (both cohorts at baseline and follow-up, all p < 0.0001) and more time in near work activities by close to 3 h compared to European Caucasian children at all ages examined (both cohorts at baseline and follow-up all, p < 0.03). The average pattern of activity for girls differed from that of boys in a similar way (both cohorts at baseline and follow-up all, p < 0.0001). The two independent samples of 12 year-old children provided by follow-up in the younger cohort and baseline in the older cohort gave very similar answers to the questionnaire, with significant differences only evident for computer use (p = 0.001) and books read (p < 0.0001). Answers to the activity questionnaire were very similar in the two

Objective Menopausal age could affect the risk of developing cardiovascular disease (CVD). The purpose of this study was to investigate the associations of early menopause (menopause occurring before 45 years of age) and menopausal age with NT-pro brain natriuretic peptide (NT-proBNP), a potential risk marker of CVD and heart failure (HF). Methods Our cross-sectional study included 2275 postmenopausal women, aged 45–85 years, without clinical CVD (2000–2002), from the Multi-Ethnic Study of Atherosclerosis. Participants were classified as having or not having early menopause. NT-proBNP was log-transformed. Multivariable linear regression was used for analysis. Results There were 561 women with early menopause. The median NT-proBNP value was 79.0 (41.1–151.6) pg/ml for all participants with values of 83.4 (41.4–164.9) pg/ml and 78.0 (40.8–148.3) pg/ml for women with and without early menopause respectively. The mean (SD) age was 65 (10.1) and 65 (8.9) years for women with and without early menopause respectively. There were no significant interactions between menopausal age and ethnicity. In multivariable analysis, early menopause was associated with a 10.7% increase in NT-proBNP while each year increase in menopausal age was associated with a 0.7% decrease in NT-proBNP. Conclusion Early menopause is associated with greater NT-proBNP levels while each year increase in menopausal age is associated with lower NT-proBNP levels in postmenopausal women. PMID:25290536

To investigate whether the association of severe mental illness with Type 2 diabetes varies by ethnicity and age. We conducted a cross-sectional analysis of data from an ethnically diverse sample of 588 408 individuals aged ≥18 years, registered to 98% of general practices (primary care) in London, UK. The outcome of interest was prevalent Type 2 diabetes. Relative to people without severe mental illness, the relative risk of Type 2 diabetes in people with severe mental illness was greatest in the youngest age groups. In the white British group the relative risks were 9.99 (95% CI 5.34, 18.69) in those aged 18-34 years, 2.89 (95% CI 2.43, 3.45) in those aged 35-54 years and 1.16 (95% CI 1.04, 1.30) in those aged ≥55 years, with similar trends across all ethnic minority groups. Additional adjustment for anti-psychotic prescriptions only marginally attenuated the associations. Assessment of estimated prevalence of Type 2 diabetes in severe mental illness by ethnicity (absolute measures of effect) indicated that the association between severe mental illness and Type 2 diabetes was more marked in ethnic minorities than in the white British group with severe mental illness, especially for Indian, Pakistani and Bangladeshi individuals with severe mental illness. The relative risk of Type 2 diabetes is elevated in younger populations. Most associations persisted despite adjustment for anti-psychotic prescriptions. Ethnic minority groups had a higher prevalence of Type 2 diabetes in the presence of severe mental illness. Future research and policy, particularly with respect to screening and clinical care for Type 2 diabetes in populations with severe mental illness, should take these findings into account. © 2016 The Authors.

A lifespan approach was used to evaluate age at menopause, and determinants of surgical and natural menopause, in the multi-ethnic community of Hilo, Hawaii. Participants aged 40-60 years (n=898) were drawn from a larger, randomly generated sample recruited by postal questionnaires. Median age at natural menopause was computed by probit analysis. Logistic regression analysis was applied to examine determinants of hysterectomy, and Cox regression analysis was used to examine risk factors for an earlier age at menopause. History of hysterectomy, age at menopause. Frequency of hysterectomy was 19.2% at a mean age of 40.5 years. The likelihood of hysterectomy increased with older ages, lower education, mixed ancestry, having been overweight at age 30, and married 20 years prior to survey. Median age at natural menopause was 53.0 years. Smoking and not being married 10 years before survey were associated with an earlier age at menopause. Median age at menopause was later than the national average. Ethnicity and education were determinants of hysterectomy, but not associated with age at natural menopause. Events later in the lifespan (e.g., smoking and not being married 10 years prior to the survey) were more important than earlier events (e.g., childhood residence) in relation to age at menopause. The timing of weight gain and marital status appear to be important in relation to surgical menopause, and the timing of marital status appears to be important in relation to the timing of natural menopause.

The prevalence of age-related maculopathy by geographic region and ethnicity.

Klein, R; Klein, B E; Cruickshanks, K J

1999-05-01

The prevalence of age-related maculopathy (ARM) varies considerably in different locations and racial/ethnic groups around the world. At present there are insufficient data to determine whether it is likely that these differences in prevalence, especially for the early forms of ARM are due to variations in genetic and environmental factors or due to variations in age of the cohorts and methods used to ascertain and define ARM. In three population-based studies of whites living in Beaver Dam, Wisconsin, Blue Mountains, Australia, and Rotterdam, The Netherlands, in which similar methods of ascertainment and classification were used to detect and define ARM, late ARM was present in 1.2%, 1.4%, and 1.2% of the population less than 86 years of age, respectively. While data from clinical studies suggest that late ARM associated with choroidal neovascularization is rare in blacks compared with whites, some epidemiological studies suggest that late ARM may be similar in blacks and whites. There are still too few data from various ethnic/racial groups around the world and too few population-based data in older Hispanic and Asian populations to make meaningful comparisons. There is a need for further research into the distribution of ARM and its possible causes using similar methodologies to ascertain and define the disease. Further insights will be gained when genotypes associated with ARM are discovered.

Menopause age can affect the risk of developing cardiovascular disease (CVD). The purpose of this study was to investigate the associations of early menopause (menopause occurring before age 45 y) and menopause age with N-terminal pro brain natriuretic peptide (NT-proBNP), a potential risk marker of CVD and heart failure. Our cross-sectional study included 2,275 postmenopausal women, aged 45 to 85 years and without clinical CVD (2000-2002), from the Multi-Ethnic Study of Atherosclerosis. Participants were classified as having or not having early menopause. NT-proBNP was log-transformed. Multivariable linear regression was used for analysis. Five hundred sixty-one women had early menopause. The median (25th-75th percentiles) NT-proBNP value was 79.0 (41.1-151.6) pg/mL for all participants, 83.4 (41.4-164.9) pg/mL for women with early menopause, and 78.0 (40.8-148.3) pg/mL for women without early menopause. The mean (SD) age was 65 (10.1) and 65 (8.9) years for women with and without early menopause, respectively. No significant interactions between menopause age and ethnicity were observed. In multivariable analysis, early menopause was associated with a 10.7% increase in NT-proBNP levels, whereas each 1-year increase in menopause age was associated with a 0.7% decrease in NT-proBNP levels. Early menopause is associated with greater NT-proBNP levels, whereas each 1-year increase in menopause age is associated with lower NT-proBNP levels, in postmenopausal women.

OBJECTIVES To examine predictors of mortality in aging Mexican Americans (MAs) and European Americans (EAs). DESIGN Longitudinal, observational cohort study. SETTING Socioeconomically diverse neighborhoods in San Antonio, Texas. PARTICIPANTS Three hundred and ninety-four MA and 355 EA community-dwelling older adults (65+) who completed the baseline examination (1992–96) of the San Antonio Longitudinal Study of Aging (SALSA) and for whom vital status was ascertained over an average 8.2 years of follow-up. MEASUREMENTS Ethnic group was classified using a validated algorithm. Hazards ratios (HR) for mortality were estimated using Cox proportional hazards models with age, sex, ethnic group, education, income, frailty, diabetes with and without complications, comorbidity, cognition, depressive symptoms, and body mass index included as predictors in sequential models. RESULTS At baseline, MAs had higher prevalence of diabetes and frailty and lower socioeconomic status (SES) compared to EAs. The age- and sex-adjusted ethnic HR (MA vs. EA) for mortality was 1.54 (95% CI: 1.17–2.03). After adjusting for SES, the ethnic HR was no longer significant (HR = 1.16, 95% CI: 0.83–1.61). In the final model, comorbidity, diabetes with complications, depressive symptoms, and cognitive impairment were significant independent risk factors for mortality. CONCLUSION Contrary to the Hispanic paradox, MAs were at increased risk of mortality. Moreover, this ethnic disparity was largely explained by SES differences. Significant independent predictors of mortality, regardless of ethnic group, included diabetes with complications, comorbidity, depressive symptoms and cognitive impairment. Mortality reduction in older MAs requires attention to both socioeconomic disparities and disease factors. PMID:24000922

To describe the prevalence of multimorbidity involving 20 selected chronic conditions in a geographically defined US population, emphasizing age, sex, and racial/ethnic differences. Using the Rochester Epidemiology Project records linkage system, we identified all residents of Olmsted County, Minnesota, on April 1, 2010, and electronically extracted the International Classification of Diseases, Ninth Revision codes associated with all health care visits made between April 1, 2005, and March 31, 2010 (5-year capture frame). Using these codes, we defined the 20 common chronic conditions recommended by the US Department of Health and Human Services. We counted only persons who received at least 2 codes for a given condition separated by more than 30 days, and we calculated the age-, sex-, and race/ethnicity-specific prevalence of multimorbidity. Of the 138,858 study participants, 52.4% were women (n=72,732) and 38.9% had 1 or more conditions (n=54,012), 22.6% had 2 or more conditions (n=31,444), and 4.9% had 5 or more conditions (n=6853). The prevalence of multimorbidity (≥2 conditions) increased steeply with older age and reached 77.3% at 65 years and older. However, the absolute number of people affected by multimorbidity was higher in those younger than 65 years. Although the prevalence of multimorbidity was similar in men and women overall, the most common dyads and triads of conditions varied by sex. Compared with white persons, the prevalence of multimorbidity was slightly higher in black persons and slightly lower in Asian persons. Multimorbidity is common in the general population; it increases steeply with older age, has different patterns in men and women, and varies by race/ethnicity.

Published nomograms of pediatric echocardiographic measurements are limited by insufficient sample size to assess the effects of age, sex, race, and ethnicity. Variable methodologies have resulted in a wide range of Z scores for a single measurement. This multicenter study sought to determine Z scores for common measurements adjusted for body surface area (BSA) and stratified by age, sex, race, and ethnicity. Data collected from healthy nonobese children ≤18 years of age at 19 centers with a normal echocardiogram included age, sex, race, ethnicity, height, weight, echocardiographic images, and measurements performed at the Core Laboratory. Z score models involved indexed parameters (X/BSA α ) that were normally distributed without residual dependence on BSA. The models were tested for the effects of age, sex, race, and ethnicity. Raw measurements from models with and without these effects were compared, and <5% difference was considered clinically insignificant because interobserver variability for echocardiographic measurements are reported as ≥5% difference. Of the 3566 subjects, 90% had measurable images. Appropriate BSA transformations (BSA α ) were selected for each measurement. Multivariable regression revealed statistically significant effects by age, sex, race, and ethnicity for all outcomes, but all effects were clinically insignificant based on comparisons of models with and without the effects, resulting in Z scores independent of age, sex, race, and ethnicity for each measurement. Echocardiographic Z scores based on BSA were derived from a large, diverse, and healthy North American population. Age, sex, race, and ethnicity have small effects on the Z scores that are statistically significant but not clinically important. © 2017 American Heart Association, Inc.

Age and ethnicity differences in storytelling to young children: emotionality, relationality, and socialization.

Pasupathi, Monisha; Henry, Risha M; Carstensen, Laura L

2002-12-01

Research has shown that age and ethnicity are associated with individuals' motivations for emotional regulation and social interaction. The authors proposed that these age and ethnicity-related motives would be reflected in storytelling. Women representing 2 age and 2 ethnic groups (young adulthood, oldage, African American, European American) told stories to young girls. Stories were coded for emotional, relational, and socialization focus. They predicted that older adults would selectively emphasize positive over negative emotions and would direct more utterances toward their interaction with their listener. The authors expected that African Americans would be more likely to emphasize socialization themes. Results suggest that older adults positively modulate emotional content while storytelling; qualified support was found for hypotheses concerning socialization and interrelational emphasis.

The prevalence of metabolic syndrome is increasing disproportionately among the different ethnicities in Asia compared to the rest of the world. This study aims to determine the differences in the prevalence of metabolic syndrome across ethnicities in Malaysia, a multi-ethnic country. In 2004, we conducted a national cross-sectional population-based study using a stratified two-stage cluster sampling design (N = 17,211). Metabolic syndrome was defined according to the International Diabetes Federation/National Heart, Lung and Blood Institute/American Heart Association (IDF/NHLBI/AHA-2009) criteria. Multivariate models were used to study the independent association between ethnicity and the prevalence of the metabolic syndrome. The overall mean age was 36.9 years, and 50.0% participants were female. The ethnic distribution was 57.0% Malay, 28.5% Chinese, 8.9% Indian and 5.0% Indigenous Sarawakians. The overall prevalence of the metabolic syndrome was 27.5%, with a prevalence of central obesity, raised triglycerides, low high density lipoprotein cholesterol, raised blood pressure and raised fasting glucose of 36.9%, 29.3%, 37.2%, 38.0% and 29.1%, respectively. Among those <40 years, the adjusted prevalence ratios for metabolic syndrome for ethnic Chinese, Indians, and Indigenous Sarawakians compared to ethnic Malay were 0.81 (95% CI 0.67 to 0.96), 1.42 (95% CI 1.19 to 1.69) and 1.37 (95% CI 1.08 to 1.73), respectively. Among those aged ≥40 years, the corresponding prevalence ratios were 0.86 (95% CI 0.79 to 0.92), 1.25 (95% CI 1.15 to 1.36), and 0.94 (95% CI 0.80, 1.11). The P-value for the interaction of ethnicity by age was 0.001. The overall prevalence of metabolic syndrome in Malaysia was high, with marked differences across ethnicities. Ethnic Chinese had the lowest prevalence of metabolic syndrome, while ethnic Indians had the highest. Indigenous Sarawakians showed a marked increase in metabolic syndrome at young ages.

Introduction The prevalence of metabolic syndrome is increasing disproportionately among the different ethnicities in Asia compared to the rest of the world. This study aims to determine the differences in the prevalence of metabolic syndrome across ethnicities in Malaysia, a multi-ethnic country. Methods In 2004, we conducted a national cross-sectional population-based study using a stratified two-stage cluster sampling design (N = 17,211). Metabolic syndrome was defined according to the International Diabetes Federation/National Heart, Lung and Blood Institute/American Heart Association (IDF/NHLBI/AHA-2009) criteria. Multivariate models were used to study the independent association between ethnicity and the prevalence of the metabolic syndrome. Results The overall mean age was 36.9 years, and 50.0% participants were female. The ethnic distribution was 57.0% Malay, 28.5% Chinese, 8.9% Indian and 5.0% Indigenous Sarawakians. The overall prevalence of the metabolic syndrome was 27.5%, with a prevalence of central obesity, raised triglycerides, low high density lipoprotein cholesterol, raised blood pressure and raised fasting glucose of 36.9%, 29.3%, 37.2%, 38.0% and 29.1%, respectively. Among those <40 years, the adjusted prevalence ratios for metabolic syndrome for ethnic Chinese, Indians, and Indigenous Sarawakians compared to ethnic Malay were 0.81 (95% CI 0.67 to 0.96), 1.42 (95% CI 1.19 to 1.69) and 1.37 (95% CI 1.08 to 1.73), respectively. Among those aged ≥40 years, the corresponding prevalence ratios were 0.86 (95% CI 0.79 to 0.92), 1.25 (95% CI 1.15 to 1.36), and 0.94 (95% CI 0.80, 1.11). The P-value for the interaction of ethnicity by age was 0.001. Conclusions The overall prevalence of metabolic syndrome in Malaysia was high, with marked differences across ethnicities. Ethnic Chinese had the lowest prevalence of metabolic syndrome, while ethnic Indians had the highest. Indigenous Sarawakians showed a marked increase in metabolic syndrome at young

Introduction Total body dual-energy x-ray absorptiometry (DXA) data offer the opportunity to compare bone density of demographic groups across the entire skeleton. Methods The present study uses total body DXA data (Hologic QDR 4500A, Hologic Inc, Bedford MA) from the National Health and Nutrition Examination Survey (NHANES) 1999–2004 to examine bone mineral density (BMD) of the total body and selected skeletal subregions in a wide age range of adult men and women from three race/ethnic groups. Total body, lumbar spine, pelvis, right leg, and left arm BMD and lean mass from 13,091 adults age 20 years and older were used. The subregions were chosen to represent sites with different degrees of weight bearing. Results Mean BMD varied in expected ways for some demographic characteristics (men>women and non-Hispanic blacks>non-Hispanic whites) but not others (non-Hispanic whites>Mexican Americans). Differences in age patterns in BMD also emerged for some characteristics (sex) but not others (race/ethnicity). Differences in cross-sectional age patterns in BMD and lean mass by degree of weight-bearing in older adults were observed for the pelvis, leg and arm. Conclusion This information may be useful for generating hypotheses about age, race, and sex differences in fracture risk in the population. PMID:19048179

Our objectives were to examine trends in the incidence of chlamydia over an extended period and compare the epidemiology of the infection between two distinct ethnic groups in Israel: Jews and Arabs. We examined the incidence rate of Chlamydia trachomatis infection among residents of Haifa District, northern Israel from 2001 to 2015, by reviewing archives of the Department of Epidemiology, Ministry of Health. Notified cases were stratified by age group, gender, and ethnic group. The overall incidence rate of Chlamydia was 10.8 cases per 100,000 population per year. The annual rate increased dramatically from 5.1 per 100,000 population in 2001, to an all-time high of 18.5 cases per 100,000 population in 2015 (P < 0.001), representing an increase of 362.7%. The most affected age group was 25-34 years of age. The estimated rate among Jewish inhabitants was ninefold higher than among Arabs. Only 3% recurrent episodes of Chlamydia were registered. The prevalence of HIV positivity among Chlamydia-infected patients was similar to that of the general population. In conclusion, Chlamydia in Haifa has been continuously increasing since 2001 and the infection is much more prevalent among patients of Jewish ethnicity, mainly due to more hazardous sexual practices in this population.

We examined the influence of sex, ethnicity, and time on competing cardiovascular and noncardiovascular causes of death following acute myocardial infarction in a multiethnic Asian cohort. For 12 years, we followed a prospective nationwide cohort of 15 151 patients (aged 22-101 years, median age 63 years; 72.3% male; 66.7% Chinese, 19.8% Malay, 13.5% Indian) who were hospitalized for acute myocardial infarction between 2000 and 2005. There were 6463 deaths (4534 cardiovascular, 1929 noncardiovascular). Compared with men, women had a higher risk of cardiovascular death (age-adjusted hazard ratio [HR] 1.3, 95% CI 1.2-1.4) but a similar risk of noncardiovascular death (HR 0.9, 95% CI 0.8-1.0). Sex differences in cardiovascular death varied by ethnicity, age, and time. Compared with Chinese women, Malay women had the greatest increased hazard of cardiovascular death (HR 1.4, 95% CI 1.2-1.6) and a marked imbalance in death due to heart failure or cardiomyopathy (HR 3.4 [95% CI 1.9-6.0] versus HR 1.5 [95% CI 0.6-3.6] for Indian women). Compared with same-age Malay men, Malay women aged 22 to 49 years had a 2.5-fold (95% CI 1.6-3.8) increased hazard of cardiovascular death. Sex disparities in cardiovascular death tapered over time, least among Chinese patients and most among Indian patients; the HR comparing cardiovascular death of Indian women and men decreased from 1.9 (95% CI 1.5-2.4) at 30 days to 0.9 (95% CI 0.5-1.6) at 10 years. Age, ethnicity, and time strongly influence the association between sex and specific cardiovascular causes of mortality, suggesting that health care policy to reduce sex disparities in acute myocardial infarction outcomes must consider the complex interplay of these 3 major modifying factors. © 2016 The Authors.

Objectives. We investigated 50-year US trends in age at menarche by socioeconomic position (SEP) and race/ethnicity because data are scant and contradictory. Methods. We analyzed data by income and education for US-born non-Hispanic Black and White women aged 25 to 74 years in the National Health Examination Survey (NHES) I (1959–1962), National Health Examination and Nutrition Surveys (NHANES) I–III (1971–1994), and NHANES 1999–2008. Results. In NHES I, average age at menarche among White women in the 20th (lowest) versus 80th (highest) income percentiles was 0.26 years higher (95% confidence interval [CI] = −0.09, 0.61), but by NHANES 2005–2008 it had reversed and was −0.33 years lower (95% CI = −0.54, −0.11); no socioeconomic gradients occurred among Black women. The proportion with onset at younger than 11 years increased only among women with low SEP, among Blacks and Whites (P for trend < .05), and high rates of change occurred solely among Black women (all SEP strata) and low-income White women who underwent menarche before 1960. Conclusions. Trends in US age at menarche vary by SEP and race/ethnicity in ways that pose challenges to several leading clinical, public health, and social explanations for early age at menarche and that underscore why analyses must jointly include data on race/ethnicity and socioeconomic position. Future research is needed to explain these trends. PMID:25033121

Understanding state/territorial trends in obesity by race/ethnicity helps focus resources on populations at risk. This study aimed to examine trends in obesity prevalence among low-income, preschool-aged children from 2008 through 2011 in U.S. states and territories by race/ethnicity. We used measured weight and height records of 11.1 million children aged 2-4 years who participated in federally funded health and nutrition programmes in 40 states, the District of Columbia and two U.S. territories. We used logistic regression to examine obesity prevalence trends, controlling for age and sex. From 2008 through 2011, the aggregated obesity prevalence declined among all racial/ethnic groups (decreased by 0.4-0.9%) except American Indians/Alaska Natives (AI/ANs); the largest decrease was among Asians/Pacific Islanders (A/PIs). Declines were significant among non-Hispanic whites in 14 states, non-Hispanic blacks in seven states/territories, Hispanics in 13 states, A/PIs in five states and AI/ANs in one state. Increases were significant among non-Hispanic whites in four states, non-Hispanic blacks in three states, Hispanics in two states and A/PIs in one state. The majority of the states/territories had no change in obesity prevalence. Our findings indicate slight reductions in obesity prevalence and variations in obesity trends, but disparities exist for some states and racial/ethnic groups. © 2015 World Obesity.

A core function of local health departments is to conduct health assessments. The analysis of death certificates provides information on diseases, conditions, and injuries that are likely to cause death - an important outcome indicator of population health. The expected years of life lost (YLL) measure is a valid, stand-alone measure for identifying and ranking the underlying causes of premature death. The purpose of this study was to rank the leading causes of premature death among San Francisco residents, and to share detailed methods so that these analyses can be used in other local health jurisdictions. Using death registry data and population estimates for San Francisco deaths in 2003-2004, we calculated the number of deaths, YLL, and age-standardized YLL rates (ASYRs). The results were stratified by sex, ethnicity, and underlying cause of death. The YLL values were used to rank the leading causes of premature death for men and women, and by ethnicity. In the years 2003-2004, 6312 men died (73,627 years of life lost), and 5726 women died (51,194 years of life lost). The ASYR for men was 65% higher compared to the ASYR for women (8971.1 vs. 5438.6 per 100,000 persons per year). The leading causes of premature deaths are those with the largest average YLLs and are largely preventable. Among men, these were HIV/AIDS, suicide, drug overdose, homicide, and alcohol use disorder; and among women, these were lung cancer, breast cancer, hypertensive heart disease, colon cancer, and diabetes mellitus. A large health disparity exists between African Americans and other ethnic groups: African American age-adjusted overall and cause-specific YLL rates were higher, especially for homicide among men. Except for homicide among Latino men, Latinos and Asians have comparable or lower YLL rates among the leading causes of death compared to whites. Local death registry data can be used to measure, rank, and monitor the leading causes of premature death, and to measure and monitor

To assess the impact of risk factors such as age, gender, ethnicity, family history, body mass index (BMI), waist circumference and hypertension, on the development of type 2 diabetes mellitus in the Trinidadian population. A cross-sectional case control study comprised 146 non-diabetics and 147 type 2 diabetics ≥18 years of age, from North Central, South West and Eastern regions of Trinidad. Cross-tabulations revealed a significant difference between type 2-diabetes and age at p<0.01, and between type 2 diabetes and family history, ethnicity, waist circumference and hypertension at p<0.05. Logistic regression showed age to be the most influential risk factor. The systolic blood pressure specifically showed a significant difference at p<0.05, with the mean values for non-diabetics and type 2 diabetics being, 130.62 (±2.124) and 141.35 (±2.312), respectively. No significant difference was observed between type 2 diabetes and gender and BMI. Age was the most significant risk factor of type 2 diabetes. Therefore it can be concluded that family history, ethnicity, waist circumference and hypertension are more significant risk factors of this disease than BMI and gender in the Trinidadian population.

We examine disparities in birth weight and gestational age by ethnic ancestry in 2000-2011 in eight South American countries. The sample included 60,480 singleton live births. Regression models were estimated to evaluate differences in birth outcomes by ethnic ancestry controlling for time trends. Significant disparities were found in seven countries. In four countries-Brazil, Ecuador, Uruguay, and Venezuela-we found significant disparities in both low birth weight and preterm birth. Disparities in preterm birth alone were observed in Argentina, Bolivia, and Colombia. Several differences in continuous birth weight, gestational age, and fetal growth rate were also observed. There were no systematic patterns of disparities between the evaluated ethnic ancestry groups across the study countries, in that no racial/ethnic group consistently had the best or worst outcomes in all countries. Racial/ethnic disparities in infant health are common in several South American countries. Differences across countries suggest that racial/ethnic disparities are driven by social and economic mechanisms. Researchers and policymakers should acknowledge these disparities and develop research and policy programs to effectively target them.

Importance Understanding the link between ethnicity and health is critical to making appropriate public policy decisions. Few population-level data are available about this connection, however, including the influence of ethnicity on the association between age-related macular degeneration (AMD) and vision-specific functioning (VSF). Objective To identify the influence of ethnicity on VSF among Chinese, Malay, and Indian patients with AMD. Design, Setting, and Participants This cross-sectional, population-based study relied on patients and their data from 3 population-based studies in 3 ethnic groups: Chinese, Malay and Indian. Of 10 033 Chinese, Malay, and Indian adults who participated in the study, 9962 (99.3%) who had gradable fundus images and Visual Function Index (VF-11) data available were included in the analyses for the present study. Uniocular presenting distance visual acuity was measured using the logMAR chart. Separate multiple linear regression models examined the association between AMD and VSF in the 3 ethnic groups, adjusting for age, sex, presenting visual acuity in the better-seeing eye, educational level, income, smoking status, hypertension, diabetes, cardiovascular disease, total cholesterol level, and other eye conditions. Data were collected between January 20, 2004, and December 19, 2011; data analysis was conducted between November 12, 2015, and December 28, 2016. Exposures Age-related macular degeneration according to fundus photographs graded using a modified Wisconsin Age-Related Maculopathy Grading System. Main Outcomes and Measures Rasch analysis was used to convert VF-11 questionnaire scores to estimated interval measures of VSF. Results Of the 9962 participants, the mean (SD) age was 58.8 (10.4) years; 4909 (49.3%) were male; 590 (5.9%) had early AMD (241 Chinese, 161 Malays, and 188 Indians) and 60 (0.6%) had late AMD (25 Chinese, 21 Malays, and 14 Indians). In the adjusted models, compared with no AMD, early AMD was

To investigate differences in ovarian reserve markers (antimüllerian hormone [AMH] and antral follicle count [AFC]) in Indian and Spanish women. Cross-sectional study. In vitro fertilization (IVF) clinics. Infertile Spanish (n=229) and Indian (n=236) women who underwent controlled ovarian stimulation for IVF from January to October 2012. None. Data on ovarian reserve markers and results after ovarian stimulation were collected. The mean age of women undergoing their first or second IVF cycle was significantly higher in Spanish than in Indian women (37.5±3.3 years vs. 31.5±3.8 years). Despite this 6-year age gap, AFCs were similar (9.5±4.7 vs. 9.9±4.6), as were day 3 FSH levels (7.5±4.5 IU/L vs. 6.9±2.3 IU/L). AMH levels were slightly lower in Spanish women (1.6±1.7 ng/mL vs. 2.5±1.6 ng/mL). Multivariate regression analysis showed that being Indian decreased AFC by 2.3, such that AFC in Indian women was similar to that in Spanish women 6.3 years older (95% confidence interval 3.39-1.10). Similar ovarian reserve markers and ovarian response were observed in women with a 6-year age difference in favor of the Spanish, suggesting ethnic differences in ovarian aging. Further research is needed to understand whether these differences are genetically induced or are caused by other variables, such as nutrition. Our results may help clinicians to counsel infertile women when discussing assisted reproductive technology outcomes according to age and ethnic background.

Cardiovascular disease by diabetes status in five ethnic minority groups compared to ethnic Norwegians

PubMed Central

2011-01-01

Background The population in Norway has become multi-ethnic due to migration from Asia and Africa over the recent decades. The aim of the present study was to explore differences in the self-reported prevalence of cardiovascular disease (CVD) and associated risk factors by diabetes status in five ethnic minority groups compared to ethnic Norwegians. Methods Pooled data from three population-based cross-sectional studies conducted in Oslo between 2000 and 2002 was used. Of 54,473 invited individuals 24,749 (45.4%) participated. The participants self-reported health status, underwent a clinical examination and blood samples were drawn. A total of 17,854 individuals aged 30 to 61 years born in Norway, Sri-Lanka, Pakistan, Iran, Vietnam or Turkey were included in the study. Chi-square tests, one-way ANOVAs, ANCOVAs, multiple and logistic regression were used. Results Age- and gender-standardized prevalence of self-reported CVD varied between 5.8% and 8.2% for the ethnic minority groups, compared to 2.9% among ethnic Norwegians (p < 0.001). Prevalence of self-reported diabetes varied from 3.0% to 15.0% for the ethnic minority groups versus 1.8% for ethnic Norwegians (p < 0.001). Among individuals without diabetes, the CVD prevalence was 6.0% versus 2.6% for ethnic minorities and Norwegians, respectively (p < 0.001). Corresponding CVD prevalence rates among individuals with diabetes were 15.3% vs. 12.6% (p = 0.364). For individuals without diabetes, the odds ratio (OR) for CVD in the ethnic minority groups remained significantly higher (range 1.5-2.6) than ethnic Norwegians (p < 0.05), after adjustment for age, gender, education, employment, and body height, except for Turkish individuals. Regardless of diabetes status, obesity and physical inactivity were prevalent in the majority of ethnic minority groups, whereas systolic- and diastolic- blood pressures were higher in Norwegians. In nearly all ethnic groups, individuals with diabetes had higher triglycerides, waist

Asthma, wheeze and eczema are common in early childhood and cause considerable morbidity. Generally rates of these conditions are higher in high income compared to low income countries. Rates in developed nations are generally higher than in less developed countries. After migration to Western countries, differences in risks of developing these conditions may between migrant and non-migrant may diminish. A convenience sample of 1648 children of White British, Pakistani or Other ethnicity aged between 4 and 5 years were recruited from the main Born in Bradford cohort. Children's parents or guardians were asked to report on a range of potential risk factors and their associations with wheeze, asthma and eczema. Relationships between ethnicity and disease outcomes were examined using logistic regression after adjustment for other relevant risk factors and confounders. Ethnic differences in doctor diagnosed asthma were evident, with children of other ethnic Origin being less likely and children of Pakistani origin more likely to have a diagnosis than White British or other origin children, although after adjustment for other risk factors this difference only remained significant for the Other Ethnic group. Ethnic differences were not observed in other outcomes including wheeze in the past 12 months, severe wheeze and taking medications for breathing problems. In UK born children, traditional risk factors such as gender, family history, socio-economic status and child's medical history may be stronger risk factors than ethnicity or familial migration patterns.

Objectives. We examined sexual orientation differences in adolescent smoking and intersections with race/ethnicity, gender, and age. Methods. We pooled Youth Risk Behavior Survey data collected in 2005 and 2007 from 14 jurisdictions; the analytic sample comprised observations from 13 of those jurisdictions (n = 64 397). We compared smoking behaviors of sexual minorities and heterosexuals on 2 dimensions of sexual orientation: identity (heterosexual, gay–lesbian, bisexual, unsure) and gender of lifetime sexual partners (only opposite sex, only same sex, or both sexes). Multivariable regressions examined whether race/ethnicity, gender, and age modified sexual orientation differences in smoking. Results. Sexual minorities smoked more than heterosexuals. Disparities varied by sexual orientation dimension: they were larger when we compared adolescents by identity rather than gender of sexual partners. In some instances race/ethnicity, gender, and age modified smoking disparities: Black lesbians–gays, Asian American and Pacific Islander lesbians–gays and bisexuals, younger bisexuals, and bisexual girls had greater risk. Conclusions. Sexual orientation, race/ethnicity, gender, and age should be considered in research and practice to better understand and reduce disparities in adolescent smoking. PMID:24825218

Total body bone density of adults from National Health and Nutrition Examination Survey (NHANES) 1999-2004 differed as expected for some groups (men>women and blacks>whites) but not others (whites>Mexican Americans). Cross-sectional age patterns in bone mineral density (BMD) of older adults differed at skeletal sites that varied by degree of weight-bearing. Total body dual-energy X-ray absorptiometry (DXA) data offer the opportunity to compare bone density of demographic groups across the entire skeleton. The present study uses total body DXA data (Hologic QDR 4500A, Hologic, Bedford MA, USA) from the NHANES 1999-2004 to examine BMD of the total body and selected skeletal subregions in a wide age range of adult men and women from three race/ethnic groups. Total body, lumbar spine, pelvis, right leg, and left arm BMD and lean mass from 13,091 adults aged 20 years and older were used. The subregions were chosen to represent sites with different degrees of weight-bearing. Mean BMD varied in expected ways for some demographic characteristics (men>women and non-Hispanic blacks>non-Hispanic whites) but not others (non-Hispanic whites>Mexican Americans). Differences in age patterns in BMD also emerged for some characteristics (sex) but not others (race/ethnicity). Differences in cross-sectional age patterns in BMD and lean mass by degree of weight-bearing in older adults were observed for the pelvis, leg, and arm. This information may be useful for generating hypotheses about age, race, and sex differences in fracture risk in the population.

The main aim of this paper was to investigate whether ethnic heath inequalities exist in self-rated health and risk-taking behaviours (smoking, drunkenness, use of cannabis) between ethnic majority (Estonian, Latvian, Lithuanian) and minority (Russian) population groups of school-aged children in three Baltic countries. Investigation was carried out in the framework of Health Behaviour in School-aged Children (HBSC) study. Randomly selected students aged 11, 13, and 15 years answered questionnaires in the classroom in 2006. In total, 14,354 questionnaire forms were selected for analysis. Russian boys were more likely (p<0.05) to evaluate their self-rated health positively in schools with Russian teaching language. Odd ratios for current smoking and drunkenness were significantly lower among Russian boys in the schools with Russian language of instruction (p<0.05) in comparison with the reference group. Russian girls did not differ significantly (the exceptions were smoking in Estonia and cannabis use in Latvia) from the majority population girls by self-rated health as well as by the risk of smoking, drunkenness, and use of cannabis. The study found some differences in self-rated health and in risk-taking behaviours between Russian minority and ethnic majority students as well as between students of schools with different language of instruction (majority language vs. Russian) in Estonia, Latvia, and Lithuania. Being a member of minority group was not related with poor self-rated health or involvement in risk-taking behaviours in school-aged children in the Baltic countries.

Insufficient data exist on population-based trends in morbidity and mortality to determine the success of prevention strategies and improvements in health care delivery in stroke. The aim of this study was to determine trends in incidence and outcome (1-year mortality, 28-day case-fatality) in relation to management and risk factors for stroke in the multi-ethnic population of Auckland, New Zealand (NZ) over 30-years. Four stroke incidence population-based register studies were undertaken in adult residents (aged ≥15 years) of Auckland NZ in 1981-1982, 1991-1992, 2002-2003 and 2011-2012. All used standard World Health Organization (WHO) diagnostic criteria and multiple overlapping sources of case-ascertainment for hospitalised and non-hospitalised, fatal and non-fatal, new stroke events. Ethnicity was consistently self-identified into four major groups. Crude and age-adjusted (WHO world population standard) annual incidence and mortality with corresponding 95% confidence intervals (CI) were calculated per 100,000 people, assuming a Poisson distribution. 5400 new stroke patients were registered in four 12 month recruitment phases over the 30-year study period; 79% were NZ/European, 6% Māori, 8% Pacific people, and 7% were of Asian or other origin. Overall stroke incidence and 1-year mortality decreased by 23% (95% CI 5%-31%) and 62% (95% CI 36%-86%), respectively, from 1981 to 2012. Whilst stroke incidence and mortality declined across all groups in NZ from 1991, Māori and Pacific groups had the slowest rate of decline and continue to experience stroke at a significantly younger age (mean ages 60 and 62 years, respectively) compared with NZ/Europeans (mean age 75 years). There was also a decline in 28-day stroke case fatality (overall by 14%, 95% CI 11%-17%) across all ethnic groups from 1981 to 2012. However, there were significant increases in the frequencies of pre-morbid hypertension, myocardial infarction, and diabetes mellitus, but a reduction in frequency

Family and neighborhood influences related to low-income were examined to understand their association with harsh parenting among an ethnically diverse sample of families. Specifically, a path model linking household income to harsh parenting via neighborhood disorder, fear for safety, maternal depressive symptoms, and family conflict was evaluated using cross-sectional data from 2,132 families with children ages 5-16 years from Chicago. The sample was 42% Mexican American, 41% African American, and 17% European American. Results provide support for a family process model where a lower income-to-needs ratio is associated with higher reports of neighborhood disorder, greater fear for safety, and more family conflict, which is in turn, associated with greater frequency of harsh parenting. Our tests for moderation by ethnicity/immigrant status, child gender, and child age (younger child vs. adolescent) indicate that although paths are similar for families of boys and girls, as well as for families of young children and adolescents, there are some differences by ethnic group. Specifically, we find the path from neighborhood disorder to fear for safety is stronger for Mexican American (United States born and immigrant) and European American families in comparison with African American families. We also find that the path from fear for safety to harsh parenting is significant for European American and African American families only. Possible reasons for such moderated effects are considered.

Empirical research on mental health care use and its determinants in young school-aged children is still scarce. In this study, we investigated the role of ethnicity, socioeconomic position (SEP) and perceived severity by both parents and teachers on mental health care use in 5- to 8-year old children with emotional and/or behavioural problems. Data from 1,269 children with a high score([P90) on the Strengths and Difficulties Questionnaire (SDQ) in the school year 2008–2009 were linked to psychiatric case register data over the years 2010–2011. Cox proportional hazards models were used to predict mental health care use from ethnicity, SEP and perceived severity of the child's problems. During the follow-up period, 117 children with high SDQ scores (9.2 %) had used mental health care for the first time. Ethnic minority children were less likely to receive care than Dutch children (HR Moroccan/Turkish:0.26; 95 % CI 0.13-0.54, HR other ethnicity: 0.26; 95 %CI 0.12-0.58). No socioeconomic differences were found.After correction for previous care use, ethnicity and parental perceived severity, impact score as reported by teachers was significantly associated with mental healthcare use (HR 1.58; 95 % CI 1.01–2.46). Ethnicity is an important predictor of mental health care use in young children. Already in the youngest school-aged children, ethnic differences in the use of mental health care are present.A distinct predictor of care use in this age group is severity of emotional and behavioural problems as perceived by teachers. Therefore, teachers may be especially helpful in the process of identifying young children who need specialist mental health care.

Well-known ethnic differences in cardiovascular risk exist, which may be explained by ethnic differences in arterial stiffness. Our aim was to assess ethnic differences in arterial stiffness, to explore whether these differences are accounted for by conventional cardiovascular risk factors, and study whether they differ across age. Cross-sectional data of 1797 Dutch, 1846 South-Asian Surinamese, 1840 African Surinamese, and 1673 Ghanaian participants of the observational HELIUS study (aged 18-70 years) were used. Arterial stiffness was assessed by duplicate pulse wave velocity (PWV) measurements using the Arteriograph system. Linear regression showed that South-Asian Surinamese had higher PWVs as compared with Dutch (age-adjusted mean difference (95% CI) was 0.55 (0.39-0.70) m/s in men and 0.82 (0.63-1.01) m/s in women). These differences were largely, but not completely, explained by conventional risk factors (particularly age and MAP). These ethnic differences were not found at young age (<35 years). African Surinamese and Ghanaians had higher PWVs as compared with Dutch across the entire age range (ranging from 0.22 (0.06-0.39) m/s in African Surinamese men to 1.07 (0.89-1.26) m/s in Ghanaian women), but these differences disappeared or reversed after adjustment for risk factors. PWV levels paralleled the well-known ethnic differences in cardiovascular risk. After adjustment for cardiovascular risk factors, however, these ethnic differences in PWV largely disappear. Together with the absence of ethnic differences in PWV at young age, our results support the hypothesis that higher PWV in South-Asian and African ethnic groups develops due to higher exposure to cardiovascular risk factors.

Obesity is a major public health problem. Detailed knowledge about the relationship between body mass index (BMI) and health-related quality of life (HRQL) is important for deriving effective and cost-effective prevention and weight management strategies. This study aims to describe the sex-, age- and ethnicity-specific association between BMI and HRQL in the US adult population. Analyses are based on pooled cross-sectional data from 41 459 participants of the Medical Expenditure Panel Survey (MEPS) Household Component (HC) for the years 2000-2003. BMI was calculated using self-reported height and weight, and HRQL was assessed with the EuroQol five-dimensional questionnaire. Generalized additive models were fitted with a smooth function for BMI and a smooth-factor interaction for BMI with sex adjusted for age, ethnicity, poverty, smoking and physical activity. Models were further stratified by age and ethnicity. The association between BMI and HRQL is inverse U-shaped with a HRQL high point at a BMI of 22 kg m -2 in women and a HRQL high plateau at BMI values of 22-30 kg m -2 in men. Men aged 50 years and older with a BMI of 29 kg m -2 reported on average five-point higher visual analog scale (VAS) scores than peers with a BMI of 20 kg m -2 . The inverse U-shaped association is more pronounced in older people, and the BMI-HRQL relationship differs between ethnicities. In Hispanics, the BMI associated with the highest HRQL is higher than in white people and, in black women, the BMI-HRQL association has an almost linear negative slope. The results show that a more differentiated use of BMI cutoffs in scientific discussions and daily practice is indicated. The findings should be considered in the design of future weight loss and weight management programs.

Objective Minority status has been implicated as a risk factor for disparate scores on cognitive function tests in older adults. Research on ethnicity and cognitive function has yielded socioeconomic status (SES), particularly education, as a primary reason for the discrepancy. Other factors, such as physical activity may provide insight into the relationship. Despite this knowledge, few studies have thoroughly examined the mediating characteristics of education or physical activity in the relationship between ethnicity and cognitive function in younger aged groups. Most research conducted focuses only on older adults during a time when degeneration of brain tissue may complicate the exploration of the relationships among ethnicity and cognitive function. The current research will expand existing knowledge about education, physical activity, and cognitive function in minority groups. Design The study presents data from the Health and Retirement Study, a nationally representative sample of late middle aged white, black, and Hispanic adults (n=9,204, mean age +-sd=55.8+-3.1). Regression and mediation testing determined the mediating effects of education and physical activity in the relationship between ethnicity and cognitive function. Results Significant association between white ethnicity and higher scores on cognitive tests was evident as early as late middle age. The magnitude of the association significantly diminished on adjusting for education and leisure time physical activity. Conclusion Our data suggest a potential mediating role of education and physical activity on the ethnic differences in cognitive tests in late middle aged white, black, and Hispanic adults. Our findings suggest a need for studies to understand if adult education and culturally-appropriate physical activity interventions in middle age influence ethnic disparities in prevalence of cognitive impairment in old age.

To examine the relationship between major depression and insulin resistance by gender and race/ethnicity among young adults without diabetes mellitus. Secondary analyses of cross-sectional data from the National Health and Nutrition Examination Survey 1999-2008 were performed (n = 2265). Major depression was measured by the Composite International Diagnostic Interview and the Patient Health Questionnaire 9. Insulin resistance was measured by the homeostasis model assessment of insulin resistance. Multivariate logistic regression analyses adjusted for risk factors of insulin resistance were conducted. There was a significant negative association between major depression and insulin resistance among men. For women, no significant association was found. There was no significant interaction between race/ethnicity and major depression on insulin resistance (Wald χ(2) = 4.2927, P = 0.2315). Body mass index (BMI) and waist circumference (WC) were significantly associated with insulin resistance among both men (odds ratio [OR] 1.255, 95% confidence interval [CI] 1.195-1.318 for BMI; OR 1.095, 95% CI 1.076-1.115 for WC) and women (OR 1.220, 95% CI 1.182-1.260 for BMI; OR 1.084, 95% CI 1.064-1.105 for WC). There are gender differences in the relationship between major depression and insulin resistance among adults aged 20-39 years. No evidence was found to support the role of race/ethnicity in this relationship. Health care professionals should be aware of risk factors for insulin resistance and develop interventions to help prevent the progression of insulin resistance to type 2 diabetes mellitus. © 2013 Ruijin Hospital, Shanghai Jiaotong University School of Medicine and Wiley Publishing Asia Pty Ltd.

Perceived ethnic discrimination (PED) is positively associated with depressive symptoms in ethnic minority groups in Western countries. Psychosocial factors may buffer against the health impact of PED, but evidence is lacking from Europe. We assessed whether ethnic identity, religion, and ethnic social network act as buffers in different ethnic minority groups in Amsterdam, the Netherlands. Baseline data were used from the HEalthy Living In a Urban Setting study collected from January 2011 to June 2014. The random sample included 2501 South-Asian Surinamese, 2292 African Surinamese, 1877 Ghanaians, 2626 Turks, and 2484 Moroccans aged 18-70 years. Depressive symptoms were assessed using the Patient Health Questionnaire-9. PED was measured with the Everyday Discrimination Scale. Ethnic identity was assessed using the Psychological Acculturation Scale. Practicing religion was determined. Ethnic social network was assessed with the number of same-ethnic friends and amount of leisure time spent with same-ethnic people. PED was positively associated with depressive symptoms in all groups. The association was weaker among (a) those with strong ethnic identity in African Surinamese and Ghanaians, (b) those practicing religion among African Surinamese and Moroccans, (c) those with many same-ethnic friends in South-Asian Surinamese, Ghanaians, and Turks, and (d) those who spend leisure time with same-ethnic people among African Surinamese and Turks. Ethnic identity, religion, and ethnic social network weakened the association between PED and depressive symptoms, but the effects differed by ethnic minority group. These findings suggest that ethnic minority groups employ different resources to cope with PED.

Neighborhood Latino ethnic concentration, above and beyond or in combination with mothers' and fathers' ethnic socialization, may have beneficial implications for minority adolescents' ethnic attitude and identity development. These hypotheses, along with two competing hypotheses, were tested prospectively (from x¯age = 12.79-15.83 years) in a sample of 733 Mexican-origin adolescents. Neighborhood ethnic concentration had beneficial implications for ethnic identity processes (i.e., ethnic exploration and perceived peer discrimination) but not for ethnic attitudes. For Mexico-born adolescents, high maternal ethnic socialization compensated for living in neighborhoods low on ethnic concentration. Findings are discussed vis-à-vis the ways in which they address major gaps in the neighborhood effects literature and the ethnic and racial identity development literature. © 2017 The Authors.

Background To identify what types of activity contribute to overall physical activity in South Asian ethnic groups and how these vary according to sex and age. We used the White British ethnic group as a comparison. Methods Self-reported physical activity was measured in the Health Survey for England 1999 and 2004, a nationally representative, cross-sectional survey that boosted ethnic minority samples in these years. We merged the two survey years and analysed data from 19 476 adults. The proportions of total physical activity achieved through walking, housework, sports and DIY activity were calculated. We stratified by sex and age group and used analysis of variances to examine differences between ethnic groups, adjusted for the socioeconomic status. Results There was a significant difference between ethnic groups for the contributions of all physical activity domains for those aged below 55 years, with the exception of walking. In women aged 16–34 years, there was no significant difference in the contribution of walking to total physical activity (p=0.38). In the 35–54 age group, Bangladeshi males have the highest proportion of total activity from walking (30%). In those aged over 55 years, the proportion of activity from sports was the lowest in all South Asian ethnic groups for both sexes. Conclusions UK South Asians are more active in some ways that differ, by age and sex, from White British, but are similarly active in other ways. These results can be used to develop targeted population level interventions for increasing physical activity levels in adult UK South Asian populations. PMID:26677257

We examined prevalence of diagnosed autism spectrum disorder (ASD) and age at diagnosis according to child's race/ethnicity and primary household language. From the 2009-2010 National Survey of Children with Special Health Care Needs, we identified 2729 3-17-year-old US children whose parent reported a current ASD diagnosis. We compared ASD prevalence, mean diagnosis age, and percentage with later diagnoses (≥5 years) across racial/ethnic/primary household language groups: non-Hispanic-white, any language (NHW); non-Hispanic-black, any language (NHB); Hispanic-any-race, English (Hispanic-English); and Hispanic-any-race, other language (Hispanic-Other). We assessed findings by parent-reported ASD severity level and adjusted for family sociodemographics. ASD prevalence estimates were 15.3 (NHW), 10.4 (NHB), 14.1 (Hispanic-English), and 5.2 (Hispanic-Other) per 1000 children. Mean diagnosis age was comparable across racial/ethnic/language groups for 3-4-year-olds. For 5-17-year-olds, diagnosis age varied by race/ethnicity/language and also by ASD severity. In this group, NHW children with mild/moderate ASD had a significantly higher proportion (50.8 %) of later diagnoses than NHB (33.5 %) or Hispanic-Other children (18.0 %). However, NHW children with severe ASD had a comparable or lower (albeit non-significant) proportion (16.4 %) of later diagnoses than NHB (37.8 %), Hispanic-English (30.8 %), and Hispanic-Other children (12.0 %). While NHW children have comparable ASD prevalence and diagnosis age distributions as Hispanic-English children, they have both higher prevalence and proportion of later diagnoses than NHB and Hispanic-Other children. The diagnosis age findings were limited to mild/moderate cases only. Thus, the prevalence disparity might be primarily driven by under-representation (potentially under-identification) of older children with mild/moderate ASD in the two minority groups.

To examine the association of perceived racial/ethnic discrimination with smoking and alcohol consumption in adults participating in the Multi-Ethnic Study of Atherosclerosis. Data on 6680 black, Chinese, Hispanic and white adults aged 45 to 84 years of age recruited from Illinois, New York, Maryland, North Carolina, Minnesota and California during 2000 and 2002 were used for this analysis. Logistic regression was used to estimate the association of perceived racial/ethnic discrimination with smoking status and alcohol consumption for each racial/ethnic group separately. Blacks were more likely to experience racial/ethnic discrimination (43%) than Hispanics (19%), Chinese participants (10%) or whites (4%, P<0.0001). In the fully-adjusted model, blacks reporting racial/ethnic discrimination had 34% and 51% greater odds of reporting smoking and drinking, respectively, than blacks who did not report racial/ethnic discrimination. Hispanics reporting racial/ethnic discrimination had 62% greater odds of heavy drinking. Whites reporting racial/ethnic discrimination had 88% greater odds of reporting being current smokers than whites who did not report racial/ethnic discrimination. Our findings suggest that the experience of discrimination is associated with greater prevalence of unhealthy behaviors. Specifically, the use of smoking and alcohol may be patterned by experience of discrimination. Copyright © 2010 Elsevier Inc. All rights reserved.

Rates of fracture worldwide are changing. Using the Clinical Practice Research Datalink (CPRD), age, and gender, geographical, ethnic and socioeconomic trends in fracture rates across the United Kingdom were studied over a 24-year period 1988-2012. Previously observed patterns in fracture incidence by age and fracture site were evident. New data on the influence of geographic location, ethnic group and socioeconomic status were obtained. With secular changes in age- and sex-specific fracture incidence observed in many populations, and global shifts towards an elderly demography, it is vital for health care planners to have an accurate understanding of fracture incidence nationally. We aimed to present up to date fracture incidence data in the UK, stratified by age, sex, geographic location, ethnicity and socioeconomic status. The Clinical Practice Research Datalink (CPRD) contains anonymised electronic health records for approximately 6.9% of the UK population. Information comes from General Practitioners, and covers 11.3 million people from 674 practices across the UK, demonstrated to be representative of the national population. The study population consisted of all permanently registered individuals aged ≥18years. Validated data on fracture incidence were obtained from their medical records, as was information on socioeconomic deprivation, ethnicity and geographic location. Age- and sex-specific fracture incidence rates were calculated. Fracture incidence rates by age and sex were comparable to those documented in previous studies and demonstrated a bimodal distribution. Substantial geographic heterogeneity in age- and sex adjusted fracture incidence was observed, with rates in Scotland almost 50% greater than those in London and South East England. Lowest rates of fracture were observed in black individuals of both sexes; rates of fragility fracture in white women were 4.7 times greater than in black women. Strong associations between deprivation and fracture

Examine the ACA Medicaid expansion effects on Medicaid take-up and private coverage through 2015 and coverage disparities by age, race/ethnicity, and gender. 2011-2015 American Community Survey for 3,137,989 low-educated adults aged 19-64 years. Difference-in-differences regressions accounting for national coverage trends and state fixed effects. Expansion effects doubled in 2015 among low-educated adults, with a nearly 8 percentage-point increase in Medicaid take-up and 6 percentage-point decline in uninsured rate. Significant coverage gains were observed across virtually all examined groups by age, gender, and race/ethnicity. Take-up and insurance declines were strongest among younger adults and were generally close by gender and race/ethnicity. Despite the increased take-up however, coverage disparities remained sizeable, especially for young adults and Hispanics who had declining but still high uninsured rates in 2015. There was some evidence of private coverage crowd-out in certain subgroups, particularly among young adults aged 19-26 years and women, including in both individually purchased and employer-sponsored coverage. The ACA Medicaid expansions have continued to increase coverage in 2015 across the entire population of low-educated adults and have reduced age disparities in coverage. However, there is still a need for interventions that target eligible young and Hispanic adults. © Health Research and Educational Trust.

Background Insufficient data exist on population-based trends in morbidity and mortality to determine the success of prevention strategies and improvements in health care delivery in stroke. The aim of this study was to determine trends in incidence and outcome (1-year mortality, 28-day case-fatality) in relation to management and risk factors for stroke in the multi-ethnic population of Auckland, New Zealand (NZ) over 30-years. Methods Four stroke incidence population-based register studies were undertaken in adult residents (aged ≥15 years) of Auckland NZ in 1981–1982, 1991–1992, 2002–2003 and 2011–2012. All used standard World Health Organization (WHO) diagnostic criteria and multiple overlapping sources of case-ascertainment for hospitalised and non-hospitalised, fatal and non-fatal, new stroke events. Ethnicity was consistently self-identified into four major groups. Crude and age-adjusted (WHO world population standard) annual incidence and mortality with corresponding 95% confidence intervals (CI) were calculated per 100,000 people, assuming a Poisson distribution. Results 5400 new stroke patients were registered in four 12 month recruitment phases over the 30-year study period; 79% were NZ/European, 6% Māori, 8% Pacific people, and 7% were of Asian or other origin. Overall stroke incidence and 1-year mortality decreased by 23% (95% CI 5%-31%) and 62% (95% CI 36%-86%), respectively, from 1981 to 2012. Whilst stroke incidence and mortality declined across all groups in NZ from 1991, Māori and Pacific groups had the slowest rate of decline and continue to experience stroke at a significantly younger age (mean ages 60 and 62 years, respectively) compared with NZ/Europeans (mean age 75 years). There was also a decline in 28-day stroke case fatality (overall by 14%, 95% CI 11%-17%) across all ethnic groups from 1981 to 2012. However, there were significant increases in the frequencies of pre-morbid hypertension, myocardial infarction, and diabetes

To evaluate age, sex, and ethnic variations in inner and outer retinal and choroidal thickness and foveal pit, using spectral-domain optical coherence tomography (SD OCT). Single-center observational cross-sectional study. Ninety randomly selected, healthy individuals of white, black, and South Asian origin underwent SD OCT raster and enhanced depth imaging scan. Manual measurements of inner and outer retinal thickness and choroidal thickness up to 3 mm nasal and temporal to the fovea were performed. The age, sex, and ethnic differences in these parameters were analyzed. The mean inner retinal thickness was lower by approximately 12 μm in black subjects across the central retina compared to white subjects (P < .05). The central foveal thickness below the foveal pit was lower in eyes of blacks compared to South Asians (12 μm, P = .035) and white subjects (18 μm, P < .0001). The fovea was also significantly wider in eyes of black and South Asian subjects compared to white individuals. The inner retinal thickness decreased by 0.5 μm per year of age of subjects and was thinner by 6.1 μm (P < .02) in female compared to male subjects. The subfoveal choroidal thickness did not vary between ethnic groups but the temporal choroid was significantly thinner in black subjects (P < .05). The choroid showed an age-related decline in thickness of 2 μm per year of age of the subjects. Interethnic differences include wider fovea, lower central foveal thickness, and thinner inner retina in eyes of black subjects compared to their white and South Asian counterparts.

Background: African Americans are at increased risk of iron deficiency (ID) but also have higher serum ferritin (SF) concentrations than those of the general population. The Hemochromatosis and Iron Overload Screening (HEIRS) Study was a multicenter study of ethnically diverse participants that tested for the hemochromatosis ( HFE ) C282Y genotype and iron status. Objective: We sought to determine the prevalence and predictors of ID (SF concentration ≤15 μg/L) and elevated iron stores (SF concentration >300 μg/L) in HEIRS women of reproductive age (25-44 y). Design: The HEIRS Study was a cross-sectional study of iron status and HFE mutations in primary care patients at 5 centers in the United States and Canada. We analyzed data for women of reproductive age according to whether or not they were pregnant or breastfeeding at the time of the study. Results: ID was present in 12.5% of 20,080 nonpregnant and nonbreastfeeding women compared with 19.2% of 1962 pregnant or breastfeeding women ( P < 0.001). Asian American ethnicity (OR ≤0.9; P ≤ 0.049) and HFE C282Y (OR ≤0.84; P ≤ 0.060) were independently associated with a decreased risk of ID in nonpregnant and nonbreastfeeding women and in pregnant or breastfeeding women. Hispanic ethnicity (OR: 1.8; P < 0.001) and African American ethnicity (OR: 1.6; P < 0.001) were associated with an increased risk of ID in nonpregnant and nonbreastfeeding women. Elevated iron stores were shown in 1.7% of nonpregnant and nonbreastfeeding women compared with 0.7% of pregnant or breastfeeding women ( P = 0.001). HFE C282Y homozygosity had the most marked independent association with elevated iron stores in nonpregnant and nonbreastfeeding women and in pregnant or breastfeeding women (OR >49.0; P < 0.001), but African American ethnicity was also associated with increased iron stores in both groups of women (OR >2.0; P < 0.001). Asian American ethnicity (OR: 1.8; P = 0.001) and HFE C282Y heterozygosity (OR: 1.9; P = 0.003) were

Doctor-patient communication is a key driver of overall satisfaction with primary care. Patients from minority ethnic backgrounds consistently report more negative experiences of doctor-patient communication. However, it is currently unknown whether these ethnic differences are concentrated in one gender or in particular age groups. To determine how reported GP-patient communication varies between patients from different ethnic groups, stratified by age and gender. Analysis of data from the English GP Patient Survey from 2012-2013 and 2013-2014, including 1,599,801 responders. A composite score was created for doctor-patient communication from five survey items concerned with interpersonal aspects of care. Mixed-effect linear regression models were used to estimate age- and gender-specific differences between white British patients and patients of the same age and gender from each other ethnic group. There was strong evidence (P<0.001 for age by gender by ethnicity three-way interaction term) that the effect of ethnicity on reported GP-patient communication varied by both age and gender. The difference in scores between white British and other responders on doctor-patient communication items was largest for older, female Pakistani and Bangladeshi responders, and for younger responders who described their ethnicity as 'Any other white'. The identification of groups with particularly marked differences in experience of GP-patient communication--older, female, Asian patients and younger 'Any other white' patients--underlines the need for a renewed focus on quality of care for these groups. © British Journal of General Practice 2016.

Ethnic differences in lipid profiles exist in children and adolescents. This study assessed whether variations in lipid profiles present in overweight and obese youth were also observed in severely obese youth. Variations could explain the lower prevalence of the metabolic syndrome in certain ethnic groups at even severe levels of obesity. Data were obtained from the National Health and Nutrition Examination Survey for the years of 2001 through 2012. Subjects were divided into groups according to BMI classification. Normal weight was defined as a BMI less than the 85th percentile. Overweight was defined as a BMI between the 85th and 95th percentile. Class 1 obesity was defined as a BMI greater than the 95th percentile up to 120% of the 95th percentile. A BMI between 120% and 140% of the 95th percentile was defined as Class 2 obesity. Class 3 was defined as a BMI above 140% of the 95th percentile. Primary outcomes were mean total cholesterol, triglyceride, low-density lipoprotein, and high-density lipoprotein levels (HDL). The sample included 14,481 non-Hispanic black (NHB) (N = 4710), non-Hispanic white (N = 4910), and Mexican American (N = 4861) subjects. Across all BMI categories, the NHB group had significantly lower mean TG and higher mean HDL levels (p < 0.0001). Ethnic variations in lipid profiles were found in severely obese youth. These findings could explain the lower prevalence of the metabolic syndrome in NHB youth. Ethnic-specific guidelines are necessary for improved identification of those at risk at all levels of obesity.

To identify what types of activity contribute to overall physical activity in South Asian ethnic groups and how these vary according to sex and age. We used the White British ethnic group as a comparison. Self-reported physical activity was measured in the Health Survey for England 1999 and 2004, a nationally representative, cross-sectional survey that boosted ethnic minority samples in these years. We merged the two survey years and analysed data from 19 476 adults. The proportions of total physical activity achieved through walking, housework, sports and DIY activity were calculated. We stratified by sex and age group and used analysis of variances to examine differences between ethnic groups, adjusted for the socioeconomic status. There was a significant difference between ethnic groups for the contributions of all physical activity domains for those aged below 55 years, with the exception of walking. In women aged 16-34 years, there was no significant difference in the contribution of walking to total physical activity (p=0.38). In the 35-54 age group, Bangladeshi males have the highest proportion of total activity from walking (30%). In those aged over 55 years, the proportion of activity from sports was the lowest in all South Asian ethnic groups for both sexes. UK South Asians are more active in some ways that differ, by age and sex, from White British, but are similarly active in other ways. These results can be used to develop targeted population level interventions for increasing physical activity levels in adult UK South Asian populations.

Rates of cannabis use differ around the world; in Ontario, the rate of use has been stable since about 2005. Understanding which population groups are at greater risk for problematic cannabis use can help reduce long-term health effects and service expenses. The aim of this study was to explore differences in cannabis use among Canadian adults of different ethnic origins living in Ontario. Data are based on telephone interviews with 11,560 respondents and are derived from multiple cycles (2005-2011) of the Centre for Addiction and Mental Health's (CAMH) Monitor survey, an ongoing cross-sectional survey of adults in Ontario, Canada, aged 18 years and older. Data were analyzed using bivariate cross-tabulations and logistic regression. Problematic cannabis use was determined with a score of 8+ on the ASSIST-CIS to identify moderate/high problematic users. Lifetime, past year and problematic cannabis use (in the past 3 months) occurs among all ethnic groups: Canadian, East Asian, South East Asian, South Asian, Caribbean, African, East European, South European, North European, and Central West European. When compared to the Canadian group the odds of past year cannabis use was significantly lower for East Asians and South Asians, but higher for the Caribbean group. Significantly higher odds of problematic cannabis use were found for Caribbeans and Northern Europeans compared to Canadians. These results of this study provide an important basis for considering the possible impact of the impending legalization of cannabis in Canada among different ethnic groups.

The Ethnic Density hypothesis posits that living around others from similar ethnic backgrounds reduces the risk of adverse mental health outcomes such as depression. Contrary to this hypothesis, previous work has shown that Hispanic ethnic density is cross-sectionally associated with increased depressive symptom severity among patients hospitalized with an acute coronary syndrome (ACS; myocardial infarction or unstable angina pectoris). To date, no study has examined the prospective association of Hispanic ethnic density on long-term depressive symptom severity following an acute medical event. We prospectively assessed the impact of Hispanic ethnic density on depressive symptoms, 1-year following an ACS event, among Hispanic adult patients. We tested the non-linear association between ethnic density and depressive symptoms to account for inconsistent findings on the ethnic density hypothesis. At the time of an index ACS event (i.e., baseline, N = 326) and 1-year later (N = 252), Hispanic patients from the Prescription Usage, Lifestyle, and Stress Evaluation prospective cohort study completed the Beck Depression Inventory as a measure of depressive symptom severity. Hispanic ethnic density was defined by the percentage of Hispanic residents within each patient's census tract using data extracted from the American Community Survey Census (2010-2013). Covariates included baseline demographic factors (age, gender, English fluency, education, nativity status), cardiovascular factors (Charlson comorbidity index, left ventricular ejection fraction, Global Registry of Acute Coronary Events 6-month prognostic risk score), and neighborhood factors (residential density, income, and percentage of households receiving public assistance). In an adjusted multivariable linear regression analysis there was a significant curvilinear association between Hispanic ethnic density and depressive symptom severity at 1 year.

Stress and coping among gay men: age and ethnic differences.

PubMed

David, Steven; Knight, Bob G

2008-03-01

Previous studies suggest that perceived stigmatization of sexual minority status, ethnicity, and age are associated with negative mental health outcomes, and other studies suggest that coping styles may influence these outcomes. However, no studies have examined these relationships among gay men of varying ethnicities and age groups. Three hundred eighty-three Black and White, younger, middle-aged, and older adult gay men completed measures of perceived stigmatization, coping style, and mental health outcomes. Black older adult gay men reported significantly higher levels of perceived ageism than the older White group, significantly higher levels of perceived racism than the younger Black group, significantly higher levels of homonegativity than the younger Black and the White groups, and were more likely to use disengaged coping styles than White gay men. However, Black older adult gay men did not experience significantly higher levels of negative mental health outcomes. Results suggest that further research should examine how older Black gay men, who perceive higher levels of stigma while reporting greater use of less effective coping styles, do not appear to be experiencing more negative mental health outcomes as a result.

Ethnicity, gender and age of onset are reported to influence the expression and outcome of systemic lupus erythematosus. We studied a multi-ethnic cohort of 408 South Africans (91.2% females) comprising 237 (58.1%) Indians, 137 (33.6%) African Blacks, 17 (4.2%) Mixed ethnicity and 17 (4.2%) Whites. The most common manifestations were arthritis (80.6%), photosensitivity (67.2%), oral ulcers (50.0%), malar rash (49.0%) and renal (39.2%). The common laboratory findings were positive anti-nuclear factor (96.8%), haematological (74.8%) and anti-dsDNA antibodies (45.3%). Serositis ( p = 0.002), nephritis ( p = 0.039), leucopaenia ( p = 0.001), haemolytic anaemia ( p = 0.026), anti-dsDNA antibodies ( p = 0.028) and anti-Sm antibodies ( p = 0.050) were more common in African Blacks compared to Indians. Males had increased prevalence of discoid rash ( p = 0.006) and anti-Sm antibodies ( p = 0.016). Discoid rash ( p = 0.018), renal involvement ( p < 0.001), psychosis ( p = 0.028), seizures ( p = 0.020), anti-dsDNA antibodies ( p = 0.009), leucopaenia ( p = 0.006), haemolytic anaemia ( p = 0.017) and thrombocytopaenia ( p = 0.023) were more common with early-onset systemic lupus erythematosus. On multivariate analysis, the independent predictors of death were renal involvement, anti-dsDNA antibodies and seizures. There were 53 (13%) deaths and the five- and 10-year survival was 90.8% and 85.7% respectively, with no differences related to ethnicity or age of onset. In conclusion, we report on the spectrum and outcome of systemic lupus erythematosus in a large South African multi-ethnic cohort.

Background Survival rates in pediatric oncology have improved dramatically, in part due to high patient participation in clinical trials. Although racial/ethnic inequalities in clinical trial participation have been reported in adults, pediatric data and studies comparing participation rates by socio-demographic characteristics are scarce. The goal of this study was to assess differences in research protocol participation for childhood cancer by age, sex, race/ethnicity, parental language, cancer type and insurance status. Procedure Data on enrollment in any protocol, biospecimen, or therapeutic protocols were collected and analyzed for newly diagnosed pediatric patients with cancer from 2008–2012 at Rady Children’s Hospital. Results Among the 353 patients included in the analysis, 304 (86.1%) were enrolled in any protocol. Enrollment in biospecimen and therapeutic protocols was 84.2% (261/310) and 81.1% (206/254), respectively. Logistic regression analyses revealed significant enrollment underrepresentation in any protocol for Hispanics compared to Non-Hispanic whites (81% vs. 91%; Odds Ratio [OR], 0.43; 95% Confidence Interval [CI], 0.21–0.90; p=0.021) and among children of Spanish-speaking vs. English-speaking parents (78% vs. 89%; OR, 0.45; 95%CI, 0.23–0.87; p=0.016). Compared to patients aged 0–4 years, significant underrepresentation was also found among patients 15–21 years old (92% vs.72%; OR, 0.21; 95% CI, 0.09–0.48; p<0.001). Similar trends were observed when analyzing enrollment in biospecimen and therapeutic protocols separately. Conclusions There was significant underrepresentation in protocol participation for Hispanics, children of Spanish-speaking parents, and patients ages 15–21. Research is urgently needed to understand barriers to research participation among these groups underrepresented in pediatric oncology clinical trials. PMID:25755225

Ethnic group discrimination represents a notable risk factor that may contribute to mental health problems among ethnic minority college students. However, cultural resources (e.g., ethnic identity) may promote psychological adjustment in the context of group-based discriminatory experiences. In the current study, we examined the associations between perceptions of ethnic group discrimination and depressive symptoms, and explored dimensions of ethnic identity (i.e., exploration, resolution, and affirmation) as mediators of this process among 2,315 ethnic minority college students (age 18 to 30 years; 37% Black, 63% Latino). Results indicated that perceived ethnic group discrimination was associated positively with depressive symptoms among students from both ethnic groups. The relationship between perceived ethnic group discrimination and depressive symptoms was mediated by ethnic identity affirmation for Latino students, but not for Black students. Ethnic identity resolution was negatively and indirectly associated with depressive symptoms through ethnic identity affirmation for both Black and Latino students. Implications for promoting ethnic minority college students' mental health and directions for future research are discussed. (PsycINFO Database Record (c) 2015 APA, all rights reserved).

Objective To study the incidence of de novo multimorbidity across all ages in a geographically defined population with an emphasis on sex and ethnic differences. Design Historical cohort study. Setting All persons residing in Olmsted County, Minnesota, USA on 1 January 2000 who had granted permission for their records to be used for research (n=123 716). Participants We used the Rochester Epidemiology Project medical records-linkage system to identify all of the county residents. We identified and removed from the cohort all persons who had developed multimorbidity before 1 January 2000 (baseline date), and we followed the cohort over 14 years (1 January 2000 through 31 December 2013). Main outcome measures Incident multimorbidity was defined as the development of the second of 2 conditions (dyads) from among the 20 chronic conditions selected by the US Department of Health and Human Services. We also studied the incidence of the third of 3 conditions (triads) from among the 20 chronic conditions. Results The incidence of multimorbidity increased steeply with older age; however, the number of people with incident multimorbidity was substantially greater in people younger than 65 years compared to people age 65 years or older (28 378 vs 6214). The overall risk was similar in men and women; however, the combinations of conditions (dyads and triads) differed extensively by age and by sex. Compared to Whites, the incidence of multimorbidity was higher in Blacks and lower in Asians. Conclusions The risk of developing de novo multimorbidity increases steeply with older age, varies by ethnicity and is similar in men and women overall. However, as expected, the combinations of conditions vary extensively by age and sex. These data represent an important first step toward identifying the causes and the consequences of multimorbidity. PMID:25649210

2014-06-01

The present study examined the associations among family connectedness, ethnic identity, and ethnic engagement on changes in well-being over time for the understudied population of Ma̅ori (indigenous New Zealand) youth. Data were collected as part of a longitudinal study of youth connectedness in New Zealand using self-report measures at 3 measurement occasions separated by 1 year each. Participants in the current study were 431 self-identified Ma̅ori (ages 10-15 years at Time 1). As expected, the variables of family connectedness, ethnic identity, and well-being were all positively related to each other. Results of a latent growth curve model showed that, following normative trends for adolescents of this age, well-being diminished over time for Ma̅ori youth; however, high levels of family connectedness were found to mitigate this general decline in well-being over time. Furthermore, in a longitudinal path analysis, ethnic engagement was found to exert a positive indirect effect on residualized Time 3 well-being through Time 2 ethnic identity. These findings indicate that the quality of family relationships and affiliation with one's ethnic group are important predictors of positive adjustment for Ma̅ori youth over time. These results are discussed in the context of positive youth development for ethnic minority and indigenous youth. PsycINFO Database Record (c) 2014 APA, all rights reserved.

Quantitative estimates of the relative risk (RR) of listeriosis among higher-risk populations and a nuanced understanding of the age-specific risks are crucial for risk assessments, targeted interventions, and policy decisions. The RR of invasive listeriosis was evaluated by age, pregnancy status, and ethnicity using 2004-2009 data from the Foodborne Diseases Active Surveillance Network (FoodNet). Nonparametric logistic regression was used to characterize changes in risk with age and ethnicity. Adjusted RRs and 95% confidence intervals (CIs) were evaluated using negative binomial generalized linear models. Among non-pregnancy-associated cases, listeriosis incidence rates increased gradually with age (45-59 years: RR, 4.7; 95% CI, 3.3-6.8; >85 years: RR, 53.8; 95% CI, 37.3-78.9; reference: 15-44 years). The RR was significantly higher for Hispanics than for non-Hispanics (RR, 1.8; 95% CI, 1.3-2.5). Among women of reproductive age (15-44 years), pregnant women had a markedly higher listeriosis risk (RR, 114.6; 95% CI, 68.9-205.1) than nonpregnant women. The RR was higher for Hispanic than non-Hispanic women, regardless of pregnancy status, and this increased during the study period (2004-2006: RR, 1.9; 95% CI, 1.0-3.3; 2007-2009: RR, 4.8; 95% CI, 3.1-7.1). This study quantifies the increases in risk of listeriosis among older persons, pregnant women, and Hispanics in the United States. Additional research is needed to better describe the independent effects of age on risk while accounting for underlying conditions. These estimates are needed both to optimize risk assessment models and to inform targeted interventions and policy decisions.

Coronary heart disease (CHD) incidence has declined significantly in the US, as have levels of major coronary risk factors, including LDL-cholesterol, hypertension and smoking, but whether trends in subclinical atherosclerosis mirror these trends is not known. To describe recent secular trends in subclinical atherosclerosis as measured by serial evaluations of coronary artery calcification (CAC) prevalence in a population over 10 years, we measured CAC using computed tomography (CT) and CHD risk factors in five serial cross-sectional samples of men and women from four race/ethnic groups, aged 55-84 and without clinical cardiovascular disease, who were members of Multi-Ethnic Study of Atherosclerosis (MESA) cohort from 2000 to 2012. Sample sizes ranged from 1062 to 4837. After adjusting for age, gender, and CT scanner, the prevalence of CAC increased across exams among African Americans, whose prevalence of CAC was 52.4% in 2000-02, 50.4% in 2003-04, 60.0% is 2005-06, 57.4% in 2007-08, and 61.3% in 2010-12 (p for trend <0.001). The trend was strongest among African Americans aged 55-64 [prevalence ratio for 2010-12 vs. 2000-02, 1.59 (95% confidence interval 1.06, 2.39); p = 0.005 for trend across exams]. There were no consistent trends in any other ethnic group. Risk factors generally improved in the cohort, and adjustment for risk factors did not change trends in CAC prevalence. There was a significant secular trend towards increased prevalence of CAC over 10 years among African Americans and no change in three other ethnic groups. Trends did not reflect concurrent general improvement in risk factors. The trend towards a higher prevalence of CAC in African Americans suggests that CHD risk in this population is not improving relative to other groups.

We estimated the effect of the ACA expansion of dependents' coverage on health care expenditures and utilization for young adults by race/ethnicity. We used difference-in-difference models to estimate the impact of the ACA expansion on health care expenditures, out-of-pocket payments (OOP) as a share of total health care expenditure, and utilization among young adults aged 19 to 26 years by race/ethnicity (White, African American, Latino, and other racial/ethnic groups), with adults aged 27 to 30 years as the control group. In 2011 and 2012, White and African American young adults aged 19 to 26 years had significantly lower total health care spending compared with the 27 to 30 years cohort. OOP, as a share of health care expenditure, remained the same after the ACA expansion for all race/ethnicity groups. Changes in utilization following the ACA expansion among all racial/ethnic groups for those aged 19 to 26 years were not significant. Our study showed that the impact of the ACA expansion on health care expenditures differed by race/ethnicity.

Acculturation or development? Autonomy expectations among ethnic German immigrant adolescents and their native German age-mates.

2012-01-01

This longitudinal study compared immigrant and native adolescents' expectations concerning the timing of conventional socially acceptable and oppositional less socially acceptable forms of autonomy. Based on normative development and a collectivist background among immigrants, both developmental and acculturative change was expected. The sample consisted of 523 ethnic German immigrants from the former Soviet Union and 475 native German adolescents, both groups divided into an early (age 12.5years) and a late (age 16years) adolescent group. Results revealed more developmental than acculturative change, as immigrants and natives mostly showed a similar rate of change in autonomy expectations. Acculturative change was found only for oppositional autonomy among late adolescent immigrants, whose later expectations approached those of their native age-mates over time. © 2012 The Authors.

The average reported age of sexual debut for youth in the United States is 14.4 years, with approximately 7% reporting their sexual debut prior to age 13. While the research literature on sexual debut for youth addresses gender and ethnic differences (with males and African-American youth experiencing earlier sexual debut), there is limited data regarding factors associated with sexual debut for young men who have sex with men (YMSM). Early sexual debut poses potential health risks, such as contracting HIV with an increased risk of unprotected intercourse. Given current high HIV infection rates for racial/ethnic minority YMSM, learning more about their sexual debuts and associated risk factors of this population is of great importance. This study investigated risk behaviors and emotional distress, and their association with MSM sexual debut for a multisite cohort of racial/ethnic minority YMSM living with HIV. We hypothesized that a MSM sexual debut younger than age 16 would be associated with engagement in more high-risk sexual behaviors (unprotected sex and exchange sex), substance use, and emotional distress than a MSM sexual debut at age 16 or older. Results indicated that participants having a MSM sexual debut before the age of 16 reported more exchange sex; drug use (specifically marijuana); emotional/psychological problems related to substance use; and a history of suicide attempts, compared to participants with later MSM sexual debuts. Comprehensive interventions that are racially/ethnically sensitive, inquire about initial sexual experiences, and focus on sexual health and healthy relationships are needed to improve health outcomes for this population.

Objective To determine if the relationships of lifetime discrimination to ambulatory blood pressure (ABP) varied as a function of age in a sample of Black and Latino(a) adults ages 19 – 65. Methods Participants were 607 Black (n = 318) and Latino(a) (n = 289) adults (49% female) who completed the Perceived Ethnic Discrimination Questionnaire-Community Version (PEDQ-CV), which assesses lifetime exposure to racism/ethnic discrimination. They were outfitted with an ABP monitor to assess systolic and diastolic blood pressure (SBP, DBP) across a 24-hour period. Mixed-level modeling was conducted to examine potential interactive effects of lifetime discrimination and age to 24-hour, daytime, and nighttime ABP after adjustment for demographic, socioeconomic, personality and life stress characteristics, and substance consumption covariates (e.g., smoking, alcohol). Results There were significant interactions of Age × Lifetime Discrimination on 24-hour and daytime DBP (ps ≤ .04), and in particular significant interactions for the Social Exclusion component of Lifetime Discrimination. Post-hoc probing of the interactions revealed the effects of Lifetime Discrimination on DBP were seen for older, but not younger participants. Lifetime discrimination was significantly positively associated with nocturnal SBP, and these effects were not moderated by age. All associations of Lifetime Discrimination to ABP remained significant controlling for recent exposure to discrimination as well as all other covariates. Conclusions Exposure to racial/ethnic discrimination across the life course is associated with elevated ABP in middle to older aged Black and Latino(a) adults. Further research is needed to understand the mechanisms linking discrimination to ABP over the life course. PMID:27018724

Understanding how race/ethnicity and gender define age-trajectories of disability: an intersectionality approach.

Warner, David F; Brown, Tyson H

2011-04-01

A number of studies have demonstrated wide disparities in health among racial/ethnic groups and by gender, yet few have examined how race/ethnicity and gender intersect or combine to affect the health of older adults. The tendency of prior research to treat race/ethnicity and gender separately has potentially obscured important differences in how health is produced and maintained, undermining efforts to eliminate health disparities. The current study extends previous research by taking an intersectionality approach (Mullings & Schulz, 2006), grounded in life course theory, conceptualizing and modeling trajectories of functional limitations as dynamic life course processes that are jointly and simultaneously defined by race/ethnicity and gender. Data from the nationally representative 1994-2006 US Health and Retirement Study and growth curve models are utilized to examine racial/ethnic/gender differences in intra-individual change in functional limitations among White, Black and Mexican American Men and Women, and the extent to which differences in life course capital account for group disparities in initial health status and rates of change with age. Results support an intersectionality approach, with all demographic groups exhibiting worse functional limitation trajectories than White Men. Whereas White Men had the lowest disability levels at baseline, White Women and racial/ethnic minority Men had intermediate disability levels and Black and Hispanic Women had the highest disability levels. These health disparities remained stable with age-except among Black Women who experience a trajectory of accelerated disablement. Dissimilar early life social origins, adult socioeconomic status, marital status, and health behaviors explain the racial/ethnic disparities in functional limitations among Men but only partially explain the disparities among Women. Net of controls for life course capital, Women of all racial/ethnic groups have higher levels of functional

Large-scale representative surveys of 8th-, 10th-, and 12th-grade students in the United States show high self-esteem scores for all groups. African-American students score highest, Whites score slightly higher than Hispanics, and Asian Americans score lowest. Males score slightly higher than females. Multivariate controls for grades and college plans actually heighten these race/ethnic/gender differences. A truncated scoring method, designed to counter race/ethnic differences in extreme response style, reduced but did not eliminate the subgroup differences. Age differences in self-esteem are modest, with 12th graders reporting the highest scores. The findings are highly consistent across 18 annual surveys from 1991 through 2008, and self-esteem scores show little overall change during that period. PMID:22279425

Objectives. We estimated the effect of the ACA expansion of dependents’ coverage on health care expenditures and utilization for young adults by race/ethnicity. Methods. We used difference-in-difference models to estimate the impact of the ACA expansion on health care expenditures, out-of-pocket payments (OOP) as a share of total health care expenditure, and utilization among young adults aged 19 to 26 years by race/ethnicity (White, African American, Latino, and other racial/ethnic groups), with adults aged 27 to 30 years as the control group. Results. In 2011 and 2012, White and African American young adults aged 19 to 26 years had significantly lower total health care spending compared with the 27 to 30 years cohort. OOP, as a share of health care expenditure, remained the same after the ACA expansion for all race/ethnicity groups. Changes in utilization following the ACA expansion among all racial/ethnic groups for those aged 19 to 26 years were not significant. Conclusions. Our study showed that the impact of the ACA expansion on health care expenditures differed by race/ethnicity. PMID:25905850

Ethnic aged discrimination and disparities in health and social care: a question of social justice.

PubMed

Johnstone, Megan-Jane; Kanitsaki, Olga

2008-09-01

Older overseas-born Australians of diverse cultural and language backgrounds experience significant disparities in their health and social care needs and support systems. Despite being identified as a 'special needs' group, the ethnic aged in Australia are generally underserved by local health and social care services, experience unequal burdens of disease and encounter cultural and language barriers to accessing appropriate health and social care compared to the average Australian-born population. While a range of causes have been suggested to explain these disparities, rarely has the possibility of cultural racism been considered. In this article, it is suggested that cultural racism be named as a possible cause of ethnic aged disparities and disadvantage in health and social care. It is further suggested that unless cultural racism is named as a structural mechanism by which ethnic aged disparities in health and social care have been created and maintained, redressing them will remain difficult.

To investigate the role of body composition (body weight, fat distribution and weight change over time) in ethnic differences in the incidence of hypertension in an ethnic Dutch, South Asian Surinamese and African Surinamese background population living in the Netherlands. We included 361 participants without hypertension at baseline (147 ethnic Dutch, 82 South Asian Surinamese, 132 African Surinamese), aged 35-60 years, in whom anthropometric measurements and blood pressures were measured at baseline and after mean 9 years of follow-up. Data were analysed using logistic regression analyses, with hypertension at follow up as a dependent variable. Body weight, fat distribution and weight gain were positively associated with the risk of developing hypertension; these associations did not statistically significantly differ between ethnic groups [odds ratios (ORs), 95% confidence interval (95% CI) per SD: BMI 1.5 (1.2-2.0); waist circumference 1.5 (1.2-1.9); waist to hip ratio (WHR) 1.4 (1.1-1.9), weight gain of 1-2.9 kg/m 1.8 (0.9-3.8)]. As compared with Dutch, a higher incidence of hypertension was found among South Asian Surinamese [OR 2.6 (1.4-4.8)] and in particular among African Surinamese [OR 3.1 (1.76-5.30)]. Among South Asian Surinamese, adjustment for WHR attenuated the OR the most [OR 1.9 (1.0-3.7)]; among African Surinamese, the strongest effect was observed for adjustment by BMI and WHR simultaneously [OR 2.5 (1.4-4.4)]. The ethnic differences in the incidence of hypertension among a middle-aged group with a Dutch, South Asian Surinamese and African Surinamese background were partly explained by body composition. This suggests that other factors may be involved, including genetic factors or unidentified other determinants.

To determine whether the relationships of lifetime discrimination to ambulatory blood pressure (ABP) varied as a function of age in a sample of Black and Latino(a) adults ages 19 - 65. Participants were 607 Black (n = 318) and Latino(a) (n = 289) adults (49% female) who completed the Perceived Ethnic Discrimination Questionnaire-Community Version (PEDQ-CV), which assesses lifetime exposure to racism/ethnic discrimination. They were outfitted with an ABP monitor to assess systolic and diastolic blood pressure (SBP, DBP) across a 24-hr period. Mixed-level modeling was conducted to examine potential interactive effects of lifetime discrimination and age to 24-hr, daytime, and nighttime ABP after adjustment for demographic, socioeconomic, personality and life stress characteristics, and substance consumption covariates (e.g., smoking, alcohol). There were significant interactions of Age × Lifetime Discrimination on 24-hr and daytime DBP (ps ≤ .04), and in particular significant interactions for the Social Exclusion component of Lifetime Discrimination. Post hoc probing of the interactions revealed the effects of Lifetime Discrimination on DBP were seen for older, but not younger participants. Lifetime discrimination was significantly positively associated with nocturnal SBP, and these effects were not moderated by age. All associations of Lifetime Discrimination to ABP remained significant controlling for recent exposure to discrimination as well as all other covariates. Exposure to racial/ethnic discrimination across the life course is associated with elevated ABP in middle to older aged Black and Latino(a) adults. Further research is needed to understand the mechanisms linking discrimination to ABP over the life course. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

There is substantial evidence to suggest that Black and minority ethnic (BME) patients are disproportionately detained under the Mental Health Act (MHA). We examined ethnic differences in patients assessed for detention and explored the effect of ethnicity after controlling for confounders. A prospective study of all MHA assessments conducted in 1 year (April 2009-March 2010) within Birmingham and Solihull Mental Health Foundation Trust, UK. Proportion of assessments and detentions within denominator population of service users and regional populations were calculated. Multiple regression analysis was conducted to determine which variables were associated with the outcome of MHA assessment and the role of ethnicity. Of the 1115 assessments, 709 led to detentions (63.58 %). BME ethnic groups were statistically more likely to be assessed and detained under the MHA as compared to Whites, both in the service user and the ethnic population estimates in Birmingham, UK. MHA detention was predicted by having a serious mental illness, the presence of risk, older age and living alone. Ethnicity was not associated with detention under the MHA with age, diagnosis, risk and level of social support accounted for. The BME 'disproportionality' in detention rates seems to be due to higher rates of mental illness, greater risk and poorer levels of social support rather than ethnicity per se.

Vitamin D intakes of children differ by race/ethnicity, sex, age, and income in the United States, 2007 to 2010.

2014-06-01

The 2007-2010 National Health and Nutrition Examination Survey was used to estimate vitamin D intakes of children 1 to 18 years old in the United States by race/ethnicity, sex, age, and family using 24-hour dietary intake recalls and dietary supplement use questionnaires. We hypothesized that total, dietary, and supplemental vitamin D intakes of children would differ by race/ethnicity, sex, age, and income. Statistical analyses of weighted data were performed using Statistical Analysis Software (V 9.2) to estimate means ± SE. Race and ethnic intake differences controlling for poverty income ratio (PIR), sex, and age were assessed by analysis of covariance. Total (dietary and supplement) vitamin D intake was greater in the high (7.9 ± 0.3 μg/d) vs the medium (6.5 ± 0.3 μg/d) income group, but not the low (7.2 ± 0.2 μg/d) PIR group. Total vitamin D intake of non-Hispanic (NH) white children (8.1 ± 0.2 μg/d) was greater than Hispanic (7.0 ± 0.2 μg/d) and NH black (5.9 ± 0.2 μg/d) children. Total vitamin D intake declined with age, and intake by boys was higher than girls. Only 17.4% of the children consumed supplements containing vitamin D. Overall, mean intake of vitamin D by all children in each age and ethnic group was lower than the estimated average requirement for vitamin D. Public health efforts should encourage consumption of foods high in vitamin D, expand the number of foods fortified, and target health messages to parents to increase use of vitamin D supplements by children.

Is the Risk of Autism in Younger Siblings of Affected Children Moderated by Sex, Race/Ethnicity, or Gestational Age?

To evaluate the recurrence risk of autism spectrum disorders (ASD) in younger siblings of affected children and determine how it is modified by race/ethnicity and sex. Medical records of children born in a large health maintenance organization (Kaiser Permanent Southern California) hospitals from January 1, 2001, through December 31, 2010, and who remained in our system until 2 to 11 years of age were used to assess the risk of recurrence of ASD in younger siblings. Children born at <28 or >42 weeks gestation, multiple births, or those who were not active members for ≥3 months were excluded. ASD diagnosis was ascertained from DSM-IV codes, and the magnitude of the association was estimated using adjusted relative risks (aRRs). Among eligible younger siblings, 592 (1.11%) had the diagnosis of ASD. The ASD rates were 11.30% and 0.92% for younger siblings of older affected and unaffected siblings, respectively (aRR: 14.27; 95% confidence interval, 11.41-17.83). This association remained after adjusting for potential confounding factors. Race/ethnicity- and gestational age-specific analyses revealed a positive association of similar magnitude across groups. Risk remained higher in younger boys than girls regardless of the sex of affected older siblings. The findings of this study suggest that the risk of ASD in younger siblings is higher if the older sibling has ASD. The risk of ASD in younger siblings of older affected siblings was comparable across gestational age at birth and child's race/ethnicity groups. However, risk remains higher for boys. This study contributes to a better understanding of the influence of race/ethnicity, sex, and gestational age at birth in identifying children at higher risk of ASD.

To examine demographic differences in frequency of use of technologies and interest in receiving nutrition information via technology by low-income parents and caregivers. Descriptive, cross-sectional study. Head Start and state-funded child care programs. A total of 806 parents and caregivers from low-income families. A 20-item survey assessed frequency of use and interest in technologies (dependent variables) and collected participant age and ethnicity (independent variables). Multivariate ANOVA analysis investigated whether age, ethnicity, and their interactions were related to frequency of use and interest in technology types. Daily rates of usage for Internet, text messaging, and cell phone use were over 60%. However, Twitter and blogs were accessed daily by < 13% of respondents. The omnibus 2-way interaction of ethnicity and age was nonsignificant. However, main effects for ethnicity (Wilks' λ = .85; F = 3.13; P < .001) and age (Wilks' λ = .89; F = 2.29; P < .001) were observed. Facebook, e-mail, texting, and smartphone applications may be innovative modalities to engage with low-income parents and caregivers aged ≤ 45. However, some strategies may be ineffective for reaching Hispanic families as they reported less use of the Internet, Facebook, and e-mail as well as less interest in e-mail.

Understanding early-life risk factors for childhood death in cystic fibrosis (CF) is important for clinical care, including the identification of effective interventions. Data from the Epidemiologic Study of Cystic Fibrosis (ESCF) collected 1994-2005 were linked with the Cystic Fibrosis Foundation Patient Registry (CFFPR) demographic and mortality data from 2013. Inclusion criteria were ≥1 visit annually at age 3-5 years and ≥1 FEV 1 measurement at age 6-8 years. Demographic data, nutritional parameters, pulmonary signs and symptoms, microbiology, and FEV 1 were evaluated as risk factors for death before age 18 years. Multivariable Cox proportional hazards regression was used to model the simultaneous effects of risk factors associated with death before age 18 years. Among 5365 patients enrolled in ESCF who met inclusion criteria, 3880 (72%) were linked to the CFFPR. Among these, 191 (5.7%) died before age 18 years; median age at death was 13.4 ± 3.1 years. Multivariable regression showed clubbing, crackles, female sex, unknown CFTR genotype, minority race or ethnicity, Medicaid insurance (a proxy of low socioeconomic status), Pseudomonas aeruginosa on 2 or more cultures, and weight-for-age <50th percentile were significant risk factors for death regardless of inclusion of FEV 1 at age 6-8 years in the model. We identified multiple risk factors for childhood death of patients with CF, all of which remained important after incorporating FEV 1 at age 6-8 years. Among the factors identified were the presence of clubbing or crackles at age 3-5 years, signs which are not routinely collected in registries. © 2017 Wiley Periodicals, Inc.

To describe the burden of dysglycemia-abnormal glucose metabolism indicative of diabetes or high risk for diabetes-among U.S. women of childbearing age, focusing on differences by race/ethnicity. Using U.S. National Health and Nutrition Examination Survey data (1999-2008), we calculated the burden of dysglycemia (i.e., prediabetes or diabetes from measures of fasting glucose, A1C, and self-report) in nonpregnant women of childbearing age (15-49 years) by race/ethnicity status. We estimated prevalence risk ratios (PRRs) for dysglycemia in subpopulations stratified by BMI (measured as kilograms divided by the square of height in meters), using predicted marginal estimates and adjusting for age, waist circumference, C-reactive protein, and socioeconomic factors. Based on data from 7,162 nonpregnant women, representing>59,000,000 women nationwide, 19% (95% CI 17.2-20.9) had some level of dysglycemia, with higher crude prevalence among non-Hispanic blacks and Mexican Americans vs. non-Hispanic whites (26.3% [95% CI 22.3-30.8] and 23.8% [19.5-28.7] vs. 16.8% [14.4-19.6], respectively). In women with BMI<25 kg/m2, dysglycemia prevalence was roughly twice as high in both non-Hispanic blacks and Mexican Americans vs. non-Hispanic whites. This relative increase persisted in adjusted models (PRRadj 1.86 [1.16-2.98] and 2.23 [1.38-3.60] for non-Hispanic blacks and Mexican Americans, respectively). For women with BMI 25-29.99 kg/m2, only non-Hispanic blacks showed increased prevalence vs. non-Hispanic whites (PRRadj 1.55 [1.03-2.34] and 1.28 [0.73-2.26] for non-Hispanic blacks and Mexican Americans, respectively). In women with BMI>30 kg/m2, there was no significant increase in prevalence of dysglycemia by race/ethnicity category. Our findings show that dysglycemia affects a significant portion of U.S. women of childbearing age and that disparities by race/ethnicity are most prominent in the nonoverweight/nonobese.

A group of 317 healthy participants between 54 and 99 years of age performed a verbal fluency task. The participants included Chinese, Hispanic, and Vietnamese immigrants, as well as White and African American English speakers. They were given 1 min to name as many animals as possible in their native language. The results showed that more animal names were produced by younger people and those with more education. Language background was also an important factor: The Vietnamese produced the most animal names and the Spanish speakers produced the fewest. The exaggerated difference between these two groups is attributed to the fact that Vietnamese animal names are short (predominantly 1 syllable) while the Spanish animal names are longer than any other language in this study (2 and 3 syllables per word). Finally, although the ethnic groups named different animals, and appeared to vary in the variety of animal names they used, these factors did not affect overall verbal fluency performance.

Serum transthyretin levels in senile systemic amyloidosis: effects of age, gender and ethnicity

Serum transthyretin (TTR) levels are reduced in familial amyloidotic polyneuropathy (FAP). A single study of patients with senile systemic amyloidosis (SSA) in Sweden found that those individuals also had a significantly lower mean serum TTR concentration than age- and gender-matched controls. To determine if the same phenomenon prevailed in an ethnically more heterogeneous population, we compared the serum TTR levels, as determined by ELISA, in 45 documented SSA patients with congestive heart failure, 20 AL patients with congestive heart failure and population controls. Serum TTR concentrations in the controls were influenced in a statistically significant manner by age, gender and ethnicity. Although it is unlikely that such differences are clinically relevant, they must be considered when assessing the meaning of serum TTR concentrations in any clinically defined population. The serum concentrations in patients with SSA did not differ from age, gender and ethnically matched controls or from a group of AL patients with significant clinical cardiac involvement. We also compared TTR concentrations in 12 African-Americans carrying the TTR V122I allele with those in 826 African-Americans who were homozygous wild type at the TTR locus. The TTR V122I carriers had significantly lower serum TTR concentrations than appropriate controls even though the majority of such individuals had not reached the age of clinical or anatomic risk, i.e. over 60. Thus, as in carriers of other TTR mutations the serum TTR level is lower than normal, despite having a much later appearance of clinical disease. PMID:19065297

While young racial/ethnic groups are the fastest growing population in the United States, data about substance-related disorders among adolescents of various racial/ethnic backgrounds are lacking. To examine the magnitude of past-year DSM-IV substance-related disorders (alcohol, marijuana, cocaine, inhalants, hallucinogens, heroin, analgesic opioids, stimulants, sedatives, and tranquilizers) among adolescents of white, Hispanic, African American, Native American, Asian or Pacific Islander, and multiple race/ethnicity. The 2005 to 2008 National Survey on Drug Use and Health. Academic research. Noninstitutionalized household adolescents aged 12 to 17 years. Substance-related disorders were assessed by standardized survey questions administered using the audio computer-assisted self-interviewing method. Of 72 561 adolescents aged 12 to 17 years, 37.0% used alcohol or drugs in the past year; 7.9% met criteria for a substance-related disorder, with Native Americans having the highest prevalence of use (47.5%) and disorder (15.0%). Analgesic opioids were the second most commonly used illegal drugs, following marijuana, in all racial/ethnic groups; analgesic opioid use was comparatively prevalent among adolescents of Native American (9.7%) and multiple race/ethnicity (8.8%). Among 27 705 past-year alcohol or drug users, Native Americans (31.5%), adolescents of multiple race/ethnicity (25.2%), adolescents of white race/ethnicity (22.9%), and Hispanics (21.0%) had the highest rates of substance-related disorders. Adolescents used marijuana more frequently than alcohol or other drugs, and 25.9% of marijuana users met criteria for marijuana abuse or dependence. After controlling for adolescents' age, socioeconomic variables, population density of residence, self-rated health, and survey year, adjusted analyses of adolescent substance users indicated elevated odds of substance-related disorders among Native Americans, adolescents of multiple race/ethnicity, adolescents of

To report robust and contemporary estimates of permanent teeth emergence ages in children of Māori, Pasifika, Chinese, Indian and European ethnic origin in the Auckland region. A stratified, two-stage cross-sectional study. Strata were defined by school decile status. Schools defined the first-stage sampling unit, and students the second stage. Invitations and consent forms were distributed to eligible participants at school for completion at home. Participants were examined at school-based clinics or in a mobile clinic. PARTICIPANTS/MATERIALS, AND METHODS: Children aged between 5 and 13 years enrolled within the Auckland Regional Dental Service. Schools were randomly selected and then all students within selected schools were invited to participate. Eligible participants completing a consent form had an additional tooth assessment that complemented their routine dental examination. A generalised gamma failure-time model was employed to estimate permanent tooth eruption ages. Visually based assessment of permanent tooth emergence. Overall, 3,466 children participated. Differences in median permanent tooth emergence ages were seen among ethnic groups and sexes (P < or = 0.01). Pasifika children had earlier median eruption time than sex-matched Māori children, who (in turn) were more advanced than sex-matched European children. Median eruption age occurred earlier in girls than boys for all permanent teeth. Despite known demographic, geographic and ethnic differences, estimates of permanent teeth emergence timing widely used in New Zealand are based on historical overseas populations. The presented estimates provide new standards and may be more appropriate for dental therapists and dentists when assessing permanent teeth emergence in New Zealand children.

In 1983-1984, 4578 Perth primary and secondary schoolchildren were studied. The selected sample was broadly representative of the ethnic groups that make up the Perth population and of the different social ranks within that population. The age, sex, weight, height, country of birth of the child and the parents, and occupation of the father were recorded for each subject. Weight, height and body mass index (BMI) increased with age. Age and sex were the most important determinants of body size. However, children of lower social rank and those with a southern European background were over-represented among the overweight children (greater than the 90th centile for BMI), particularly in adolescence. Children with an Asian background who were 11 years of age and younger were over-represented among the underweight children (less than or equal to the 10th centile for BMI). Results from this study indicate a continuing, though small (1.5 cm to 1.6 cm), secular increase in height over the past 13 to 14 years.

Given the expected increase in the number of patients with osteoporosis and fragility fractures it is important to have concise information on trends in prescription rates of anti-osteoporosis drugs (AOD). We undertook a retrospective observational study using the UK Clinical Practice Research Datalink (CPRD) in the UK between 1990 and 2012 in subjects 50years or older, stratified by age, sex, geographic region and ethnicity. Yearly prescription incidence rates of any AOD and of each specific AOD were calculated as the number of patients first prescribed these AODs per 10,000person-years (py). In women, yearly rates of first prescription of any AOD increased from 1990 to 2006 (from 2.3 to 169.7 per 10,000py), followed by a plateau and a 12% decrease in the last three years. In men, a less steep increase from 1990 to 2007 (from 1.4 to 45.3 per 10,000py) was followed by a plateau from 2008 onwards. Yearly rates of first prescription of any AOD increased up to the age of 85-89years (248.9 per 10,000py in women and 119.3 in men). There were marked differences between ethnic groups and regions. Bisphosphonates were the most frequently prescribed AODs: etidronate till 2000, and then subsequently alendronate. We have demonstrated marked secular changes in rates of anti-osteoporosis drug prescription over the last two decades. The plateau (and decrease amongst women) in rates in recent years, set against an ever ageing population, is worrying, suggesting that the well-documented care gap in osteoporosis treatment persists. The differences in prescription rates by geographic location and ethnicity raise intriguing questions in relation to underlying fracture rates, provision of care and health behaviour. We studied the prescription incidence of anti-osteoporosis drugs (AOD) from 1990 to 2012 in the UK CPRD. Overall AOD prescription incidence showed a strong increase from 1990 to 2006, followed by a plateau in both sexes and a decrease amongst women in the last three years

Incidence and prevalence rates of multiple sclerosis (MS) are generally higher in White populations than in other ethnic groups. Relevant studies in the United Kingdom were conducted over 30 years ago. To provide updated ethnicity-specific MS prevalence rates in the United Kingdom. Electronic records from general practices (GPs) in four east London boroughs were queried for the number of people diagnosed with MS, grouped by ethnicity, into 5-year age bands. Compared against total registered GP patients in the area (c. 900,000), the age-standardised MS prevalence was calculated by ethnic group. The overall age-standardised prevalence of MS was 111 per 100,000 (152 for women and 70 for men), and 180, 74 and 29 for the White, Black and South Asian populations, respectively. The sex ratios (female:male) were 2.2:1, 2.1:1 and 2.8:1, respectively. MS prevalence was considerably lower among Black and South Asian populations, compared to the White population, by 59% and 84%, respectively. However, compared to available data in Africa and South Asia, MS is several times more prevalent among Black people and South Asians living in the United Kingdom than their territorial ancestry.

Age-specific incidence rates for breast cancer in low-risk and high-risk ethnic populations differ by age at which the incidence maximum is reached: around 50 years in low-risk populations and over 60 years in high-risk populations. The interpretation of these differences remains unsettled, one line primarily referring to biological differences, the second one to cohort effects of rapidly increasing rates in young populations, and the third one to incomplete registration of cancer in the elderly. The nationwide Family-Cancer Database was used to analyze standardized incidence ratios (SIRs) and age at diagnosis of breast cancer in female immigrants to Sweden by their region of origin compared with women native to Sweden matched on birth year and other relevant factors. We showed first that the SIRs for breast cancer were lower in many immigrant groups compared with natives of Sweden; women from Turkey had the lowest SIR of 0.45, followed by those from Chile (0.54) and Southeast Asia (0.57). Women from nine regions showed an earlier mean age at diagnosis than their matched Swedish controls, the largest differences being 5.5 years for women from Turkey, 5.1 years for those from Asian Arab and "Other African" countries, 4.3 years for those from Iran, and 4.0 years for those from Iraq. The results show that in many immigrant groups, the diagnostic age is earlier (<50 years) than in natives of Sweden (>50 years), suggesting that true biological factors underlie the differences. These factors may explain much of the international variation in breast cancer incidence. Identifying these factors should advance understanding of breast cancer etiology and prevention.

Risk for Maternal Harsh Parenting in High-Risk Families From Birth to Age Three: Does Ethnicity Matter?

Fisher, Philip A.; Kim, Hyoun K.

2017-01-01

Child maltreatment prevention programs typically identify at-risk families by screening for risk with limited consideration of how risk might vary by ethnicity. In this study, longitudinal data from mothers who participated in a randomized clinical trial of a home-visitation, child maltreatment prevention program (N=262) were examined to determine whether risk for harsh parenting differed among mothers who identified themselves as Spanish-speaking Latinas (n=64), English-speaking Latinas (n=102), or non-Latina Caucasians (n=96). The majority of the participants were first-time mothers (58.4%), and the average age of all participants was 23.55 years (SD=6.04). At the time of their infants’ births, the Spanish-speaking Latina mothers demonstrated higher SES risk, whereas the English-speaking Latina and non-Latina Caucasian mothers demonstrated higher psychosocial risk. Three years later, the English-speaking Latina and non-Latina Caucasian mothers reported harsher parenting behaviors than the Spanish-speaking Latina mothers. The need for prevention programs to consider how risk and protective factors differ by ethnic group membership when identifying at-risk mothers is discussed. PMID:21935658

Family meals may improve diet and weight outcomes in children; however, results from nationally representative samples suggest these relationships vary by race/ethnicity. Observing parent-child mealtime interactions may lend insight to why racial/ethnic differences exist. In this pilot study, a multi-ethnic sample of low-income families (n=30) with a preschool-age child were videotaped during a dinner in their home. A global coding scheme was used to assess the following: `Action' (behaviors that divert attention from eating), `Behavior Control' (behaviors intended to modify another person's behavior), and `Communication' (i.e., meal-oriented, interpersonal, and critical). All families spent a significant amount of time in `action' oriented behaviors that diverted their attention from eating. We also observed racial/ethnic differences in communication (i.e. critical) and behavior patterns (i.e. behavior control). This study demonstrated that this approach for observing parent-child mealtime interactions in a naturalistic setting among a diverse study sample was feasible; however, future studies should address how these patterns relate to dietary intake and weight status.

Data from National Health and Nutrition Examination Survey for the period 2011-2012 were used to determine normal reference ranges and percentile distributions for manganese (Mn) and selenium (Se) in blood by gender, age, race/ethnicity, socioeconomic status as determined by annual family income, and smoking status. The effect of gender, age, race/ethnicity, family income, and smoking status on the levels of Mn and Se was also determined by fitting regression models. Males had lower adjusted levels of Mn and higher adjusted levels of Se than females. Adjusted levels of Mn decreased with increase in age but adjusted levels of Se were lower in adolescents aged 12-19 years than adults aged 20-64 years. Non-Hispanic black (NHB) had the lowest levels of both Mn and Se and non-Hispanic Asians (NHAS) had the highest levels of both Mn and Se. Non-Hispanic white (NHW) and NHB had lower levels of Mn than Hispanics (HISP) and NHAS. NHB and HISP had lower levels of Se than NHW and NHAS. Low annual income (<$20,000) was associated with lower levels of Se than high annual income (≥$55,000). Smoking negatively affected the adjusted levels of Se among seniors aged ≥65 years but this was not observed in other age groups. Mn levels were not affected by smoking. Published by Elsevier GmbH.

We investigated the contribution of ethnicity, physical activity, body composition, and calcium intake to bone accrual across 7 years of growth. We assessed 80 Caucasian and 74 Asian boys and 81 Caucasian and 64 Asian girls at baseline and retained 155 children across all 7 years. Ethnicity, physical activity, and calcium intake were assessed by questionnaire; fat mass, lean mass, and bone mineral content (BMC) of the whole body (WB), lumbar spine (LS), total proximal femur (PF(TOT)), and femoral neck (FN) were measured using DXA (Hologic QDR 4500). We aligned children on peak height velocity and utilized multilevel modeling to assess bone mineral accrual. Height and lean mass accounted for 51.8% and 44.1% of BMC accrual in children. There was a significant difference in physical activity, calcium intake, and lean mass between Asians and Caucasian boys and girls at baseline and conclusion (p < 0.05). In boys, physical activity and ethnicity significantly predicted BMC accrual at the FN. In girls, Asians had significantly lower PF(TOT) and FN BMC. Calcium was a significant predictor of WB BMC accrual in boys and girls. In conclusion, our findings highlight the importance of accounting for ethnicity in pediatric studies. Physical activity, dietary calcium, and lean mass positively influence bone accrual and are lower in Asian compared to Caucasian children from a very young age.

This article highlights methods of ending life in different ethnic groups. This inference is drawn from analysis of data from suicidal cases from the University Malaya Medical Centre mortuary. This study also looked at sex, age, social, and employment factors. Kuala Lumpur has sizeable populations of Muslims, Chinese, Indians and Indonesian, etc. This study is based on 251 cases of suicide that were reported at the University Malaya Medical Centre from 2000 to 2004. Malaysia has a population of 22,662,365 people with 3 major ethnic groups: Malay (58%), Chinese (24%), and Indians (8%) with a minority of "others" (10%), which includes foreigners, Sabahan, and Sarawakian. This research found suicides of 164 male (65%) and 87 female (35%) victims. Their age ranged from 15 to 80 years. The age group from 21 to 30 had the highest total cases of suicide (83 of 251; 33.1%). Among ethnic groups highest rate of suicide was among Chinese with a total of 120 cases (120 of 251; 47.8%). As far as lone method of suicide is concerned, hangings accounted for the highest proportion of cases (108 of 251; 43%). Among ethnic groups, jumping from height was the commonest method used by Chinese (49 of 120; 41%), Malay (9 of 16; 56%), and others (15 of 28; 53.4%); whereas, hanging was the commonest method of committing suicide by Indians (49 of 87); Muslims showed the lowest cases of suicide (18 of 251; 7.2%). In poisoning group Indian was the highest ethnic group who used this method (20 of 37; 54.1%).

To investigate the prevalence rate of thalassemia among children of 0 - 7 years old, from six ethnic groups in Xishuangbanna and Dehong, Yunnan province. 4973 blood samples from children under 7 years old were automatically undergone blood cell count, red cell osmotic fragility and hemoglobin electrophoresis testings. The incidence rates of thalassaemia, β-thalassemia was 37.4%, and α-thalassaemia were 22.6% and 14.7% respectively. The thalassaemia incidence rates were significantly different among age groups but not in gender. The incidence of α-thalassaemia was decreasing along with the increase of age, while the incidence of β-thalassaemia was increasing along with the increase of age. Xishuangbanna had the higher incidence than in Dehong and the differences were significant between counties, The incidence of thalassemia of Mengla ranked the first (52.2%) in Xishuangbanna, The differences between different regions and different nationalities were significant, with β-thalassemia of Achang ranked the first (40.6%), The incidence of α-thalassemia among Han ranked the first as 45.5% while α-thalassaemia and β-thalassemia were different in regions. α-thalassaemia and β-thalassemia were significantly different between different ethnic people in the same regions. Multiple factor analysis showed that region seemed to be a risk factor and the mother's ethnicity was a protective factor and dependent variable on thalassaemia. The incidence of thalassaemia in Yunnan Xishuangbanna and Dehong was high among children under the age of 7 and were related to ethnic and regional differences in the areas. Specific genes were proliferated along with the extension of time. Our data provided valuable information on prevention and genetic studies on thalassaemia in the minorities of Xishuangbanna and Dehong in Yunnan province.

This study investigated age, sex, and race/ethnicity risk patterns for homicide based on 246 children (newborn to 14 years old) who were murdered in the city of Los Angeles 1980 through 1989. Rates of homicide are higher for newborn to 4-year-olds than for 5- to 14-year-olds. Boys and girls have similar rates of homicide at young ages; among 5- to 14-year-olds, however, boys have higher rates. Characteristics of the victim, suspect, and event were fairly consistent across victim race/ethnicity. Rates vary by the victim's race/ethnicity; paralleling patterns among adults, rates of homicide are lowest for non-Hispanic White, higher for Hispanic, and highest for Black children. PMID:8484456

The Multigroup Ethnic Identity Measure-Revised (MEIM-R), a brief instrument assessing affiliation with one’s ethnic group, is a promising advance in the ethnic identity literature. However, equivalency of its measurement properties across specific racial and ethnic groups should be confirmed before using it in diverse samples. We examined a) the psychometric properties of the MEIM-R including factor structure, measurement invariance, and internal consistency reliability, and b) levels of and differences in ethnic identity across multiple racial and ethnic groups and subgroups. Asian (n = 630), Black/African American (n = 58), Hispanic (n = 240), multiethnic (n = 160), and White (n = 375) women completed the MEIM-R as part of the “Gestational diabetes’ Effect on Moms” diabetes prevention trial in the Kaiser Permanente Northern California health care setting (N = 1,463; M age 32.5 years, SD = 4.9). Multiple-groups confirmatory factor analyses provided provisional evidence of measurement invariance, i.e., an equal, correlated two-factor structure, equal factor loadings, and equal item intercepts across racial and ethnic groups. Latent factor means for the two MEIM-R subscales, exploration and commitment, differed across groups; effect sizes ranging from small to large generally supported the notion of ethnic identity as more salient among people of color. Pending replication, good psychometric properties in this large and diverse sample of women support the future use of the MEIM-R. Preliminary evidence of measurement invariance suggests that the MEIM-R could be used to measure and compare ethnic identity across multiple racial and ethnic groups. PMID:24188656

Background Studies suggest that neighborhood ethnic diversity may be important when it comes to understanding ethnic inequalities in mental health. The primary aim of this study was to investigate whether neighborhood ethnic diversity moderated the association between the ethnic minority status and child behavioral and emotional problems. Methods We included 3076 preschoolers participating in the Generation R Study, a birth cohort study in Rotterdam, the Netherlands. At child age 3-years, parents completed the Child Behavior Checklist (CBCL/1,5-5). Individual-level data, assessed with questionnaires, was combined with neighborhood-level data. Multi-level logistic regression models predicted the Odds Ratios for the CBCL total problems score as a function of maternal ethnic background and neighborhood ethnic diversity, computed with the Racial Diversity Index and categorized into tertiles. Interaction on the additive scale was assessed using Relative Access Risk due to Interaction. Results Being from an ethnic minority was associated with child behavioral and emotional problems in unadjusted (OR 2.76, 95% CI 1.88–4.04) and adjusted models (OR 2.64, 95% CI 1.79–3.92). Residing in a high diversity neighborhood was associated with child behavioral and emotional problems in unadjusted (OR 2.03, 95% CI 1.13–3.64) but not in adjusted models (OR 0.89, 95% CI 0.51–1.57). When stratifying by the three levels of neighborhood ethnic diversity, ethnic inequalities in behavioral and emotional problems were greatest in low diversity neighborhoods (OR 5.24, 95%CI 2.47–11.14), smaller in high diversity neighborhoods (OR 3.15, 95% CI 1.66–5.99) and smallest in medium diversity neighborhoods (OR 1.59, 95% CI 0.90–2.82). Tests for interaction (when comparing medium to low diversity neighborhoods) trended towards negative on both the additive and multiplicative scale for the maternal-report (RERI: −3.22, 95% CI −0.70–0.59; Ratio of ORs: 0.30, 95% CI 0.12–0

A study was undertaken to examine temporal trends and ethnic differences in the asthma mortality rate in Singapore. Asthma mortality rates in Singapore were estimated from vital data for the years from 1976 to 1995. Trends in sex and age specific (5-14, 15-34, 35-59, 60+ years) rates were obtained for four periods (1976-80, 1981-85, 1986-90, 1991-95) and for Chinese, Malay, and Indian subjects for the years when these data were available (1989-95). An increase in asthma mortality was observed in children aged 5-14 years from 0.21 per 100,000 person years in 1976-80 to 0.72 per 100,000 person years in 1991-95. No increases were noted in the other age groups but a small decrease was observed in the 1991-95 period for the 35-59 year age group. Marked ethnic differences in mortality rates were observed. In the group aged 5-34 years the asthma mortality rates were 0.5 per 100,000 in Chinese subjects, 1.3 per 100,000 in Indians, and 2.5 per 100,000 in Malay subjects. Similar 2-4 fold differences were observed in all other age groups. Apart from genetic factors, environmental exposures and medical care factors which influence asthma prevalence and severity are most likely to be the causes of the observed temporal trends and ethnic differences in the asthma mortality rate in Singapore, but further studies are needed to elucidate these more fully.

Does the Breast Cancer Age at Diagnosis Differ by Ethnicity? A Study on Immigrants to Sweden

PubMed Central

Hemminki, Kari; Sundquist, Jan; Brandt, Andreas

2011-01-01

Background. Age-specific incidence rates for breast cancer in low-risk and high-risk ethnic populations differ by age at which the incidence maximum is reached: around 50 years in low-risk populations and over 60 years in high-risk populations. The interpretation of these differences remains unsettled, one line primarily referring to biological differences, the second one to cohort effects of rapidly increasing rates in young populations, and the third one to incomplete registration of cancer in the elderly. Methods. The nationwide Family-Cancer Database was used to analyze standardized incidence ratios (SIRs) and age at diagnosis of breast cancer in female immigrants to Sweden by their region of origin compared with women native to Sweden matched on birth year and other relevant factors. Results. We showed first that the SIRs for breast cancer were lower in many immigrant groups compared with natives of Sweden; women from Turkey had the lowest SIR of 0.45, followed by those from Chile (0.54) and Southeast Asia (0.57). Women from nine regions showed an earlier mean age at diagnosis than their matched Swedish controls, the largest differences being 5.5 years for women from Turkey, 5.1 years for those from Asian Arab and “Other African” countries, 4.3 years for those from Iran, and 4.0 years for those from Iraq. Conclusions. The results show that in many immigrant groups, the diagnostic age is earlier (<50 years) than in natives of Sweden (>50 years), suggesting that true biological factors underlie the differences. These factors may explain much of the international variation in breast cancer incidence. Identifying these factors should advance understanding of breast cancer etiology and prevention.

Background Invasive melanoma of the skin is the third most common cancer diagnosed among adolescents and young adults (aged 15-39 years) in the United States. Understanding the burden of melanoma in this age group is important to identifying areas for etiologic research and in developing effective prevention approaches aimed at reducing melanoma risk. Methods Melanoma incidence data reported from 38 National Program of Cancer Registries and/or Surveillance Epidemiology and End Results statewide cancer registries covering nearly 67.2% of the US population were used to estimate age-adjusted incidence rates for persons 15-39 years of age. Incidence rate ratios were calculated to compare rates between demographic groups. Results Melanoma incidence was higher among females (age-adjusted incidence rates = 9.74; 95% confidence interval 9.62-9.86) compared with males (age-adjusted incidence rates = 5.77; 95% confidence interval 5.68-5.86), increased with age, and was higher in non-Hispanic white compared with Hispanic white and black, American Indians/Alaskan Natives, and Asian and Pacific Islanders populations. Melanoma incidence rates increased with year of diagnosis in females but not males. The majority of melanomas were diagnosed on the trunk in all racial and ethnic groups among males but only in non-Hispanic whites among females. Most melanomas were diagnosed at localized stage, and among those melanomas with known histology, the majority were superficial spreading. Limitations Accuracy of melanoma cases reporting was limited because of some incompleteness (delayed reporting) or nonspecific reporting including large proportion of unspecified histology. Conclusions Differences in incidence rates by anatomic site, histology, and stage among adolescents and young adults by race, ethnicity, and sex suggest that both host characteristics and behaviors influence risk. These data suggest areas for etiologic research around gene-environment interactions and the need for

Racial/ethnic minorities bear a disproportionate burden of alcohol-related problems in the U.S. It is unknown whether this reflects harmful patterns of lifecourse heavy drinking. Prior research shows little support for the latter but has been limited to young samples. We examine racial/ethnic differences in heavy drinking trajectories from ages 21 to 51. Data on heavy drinking (6+ drinks/occasion) are from the 1979 National Longitudinal Survey of Youth (N=9468), collected between 1982 and 2012. Sex-stratified, generalized estimating equations (GEE) were used to model heavy drinking frequency trajectories as a function of age with a cubic curve, and interactions of race with age terms were tested to assess racial/ethnic differences. Models adjusted for time-varying socioeconomic status and marital and parenting status; predictors of trajectories were examined in race- and sex-specific models. White men and women had similarly steep declines in heavy drinking frequency throughout the 20s, contrasting with slower declines (and lower peaks) in Black and Hispanic men and women. During the 30s there was a Hispanic-White crossover in men's heavy drinking curves, and a Black-White female crossover among lifetime heavy drinkers; by age 51, racial/ethnic group trajectories converged in both sexes. Greater education was protective for all groups. Observed racial/ethnic crossovers in heavy drinking frequency following young adulthood might contribute to disparities in alcohol-related problems in middle adulthood, and suggest a need for targeted interventions during this period. Additionally, interventions that increase educational attainment may constitute an important strategy for reducing heavy drinking in all groups. Copyright © 2016 Elsevier Ireland Ltd.

Patterns and Trends in Elder Homicide Across Race and Ethnicity, 1985-2009

Feldmeyer, Ben; Steffensmeier, Darrell

2014-01-01

In this report, we assess total and race/ethnicity-disaggregated patterns and temporal trends in elderly homicide (age 55-74) compared with younger age groups for the 1985-to-2009 period. To do this, we use California arrest statistics that provide annual homicide figures by race and ethnicity (including a Hispanic identifier) and by age. Major aims of our analysis are to establish whether (a) elderly homicide rates are different/similar across race/ethnic comparisons; (b) the elderly share of homicide and age-homicide distributions more generally differ across race/ethnicity; and (c) elderly rates of homicide and the share of elderly homicide relative to younger age groups is similar or different now as compared with 20 to 30 years ago. Our analysis is important and timely because some commentators have suggested that elderly homicide levels have been rising over the past one to two decades and because there is a virtual absence of research of any sort on elderly homicide trends that involve comparisons by race and ethnicity. Key findings are that elderly shares of homicide offending relative to younger ages have not increased (or decreased), that elder homicides continue to account for a small fraction of all homicides, and that these patterns persist across race/ethnicity comparisons.

2008-01-01

An important question for the acculturation of adolescents from immigrant families is whether they retain ethnic labels that refer to their national origin (e.g., Mexican, Chinese) or adopt labels that are dominant in American society (e.g., Latino, Asian American, American). Approximately 380 adolescents from Asian and Latin American immigrant families selected ethnic labels during each of the 4 years of high school (age span = 14.87-17.82 years). Results indicated no normative trend either toward or away from identifying most closely with pan-ethnic or American ethnic labels. Significant numbers of adolescents changed their ethnic labels from year to year, however and these changes were associated with fluctuations in adolescents' ethnic affirmation and exploration and proficiency in their heritage languages.

Objectives Whether racial/ethnic differences in prevalence/reporting of sleep disorders exist in pregnant women/women of child-bearing age is unknown. Study objectives were to estimate prevalence of sleep disorders and to examine racial/ethnic differences in sleep disorders, reporting of sleep issues, and amount of sleep among women of child-bearing age (15-44 years) in the US. Methods Through a secondary analysis of the National Health and Nutrition Examination Survey 2005-2010 (3175 non-pregnant, 432 pregnant women in main analysis), prevalence of sleep disorders, reporting of sleep disorders to a physician/health professional, and amount of sleep were estimated overall, by pregnancy status, and by race/ethnicity stratified by pregnancy status. Racial/ethnic differences in reporting of trouble sleeping by pregnancy status were examined using univariate and multivariate logistic regression. Results Prevalence of diagnosed sleep disorders among women of childbearing age was 4.9 % [3.9 % pregnant; 5.1 % non-pregnant (p < 0.01)]. Significantly fewer pregnant and non-pregnant minority women reported adequate sleep (7-8 h) than non-Hispanic white (white) women (p < 0.05). Among non-pregnant women, odds of report of trouble sleeping were significantly higher for white compared to black (aOR 0.47 [95 % CI 0.36, 0.61]) or Mexican-American women (aOR 0.29 [95 % CI 0.21, 0.41]); non-pregnant minority women were also significantly less likely to report trouble sleeping than white women when controlling for amount of sleep. Among pregnant women, these same trends were found. Discussion Compared to white women, minority women, despite reporting less adequate sleep, are less likely to report trouble sleeping, providing evidence of an important health disparity.

Ethnic variations in parental ethnic socialization and adolescent ethnic identity: a longitudinal study.

PubMed

Else-Quest, Nicole M; Morse, Emily

2015-01-01

Achievement of a positive ethnic identity has been linked to positive outcomes for ethnic minority youth and is fostered by parental ethnic socialization practices. In light of findings of variability in developmental trajectories and outcomes, we examined ethnic group variations in parents' ethnic socialization practices and adolescents' ethnic identity. Within a sample of 370 adolescents who self-identified as White, African American, Latino/a, or Asian American, and their parents, parental ethnic socialization practices (including preparation for bias, promotion of mistrust, and cultural socialization) and adolescent ethnic identity development (including identity exploration and commitment) were assessed at 10th and 11th grades. Consistent with predictions, African American youth reported higher levels of ethnic identity exploration and commitment than youth from other ethnic groups, and parents of African American youth tended to report higher levels of ethnic socialization than other parents. Parental cultural socialization significantly predicted adolescent ethnic identity exploration and commitment 1 year later; ethnicity did not moderate this link. Findings are discussed in the context of the schools and urban community from which the sample was recruited, highlighting the importance of sociocultural context in development.

Attention-deficit/hyperactivity disorder (ADHD) is the most commonly diagnosed mental disorder among children in the United States. While overall ADHD prevalence continues to rise, few have examined difference by race/ethnicity. To examine trends in parent-reported ADHD prevalence between 2003 and 2011 across racial/ethnic groups and the role of sociodemographic factors in observed differences in ADHD. Data were from 3 waves of the National Survey of Children's Health (2003, 2007, and 2011), including 190,408 children aged 5-17 years. Independent variables included race/ethnicity (white non-Hispanic, black non-Hispanic, Hispanic, other non-Hispanic), gender, age, poverty level, primary language, insurance status, parental marital status, and neighborhood safety. Sociodemographic factors and year were compared among those diagnosed with ADHD and between racial/ethnic groups using χ(2) tests. Adjusted logistic regression models, stratified by race/ethnicity, were fit to examine the association between identified risk factors and ADHD across racial/ethnic groups. Parental report of an ADD or ADHD diagnosis for a child aged 5-17 years was the dependent variable. If the household included more than 1 child aged 5-17 years, 1 was selected at random. Increasing trends were observed over the past decade in the prevalence of parent-reported ADHD overall (43%, P < .001), among children aged 10-14 years (47%, P < .001), and adolescents aged 15-17 years (52%, P < .001). Although the ADHD prevalence was still highest among whites, increasing trends were observed for all racial/ethnic groups, most notably among Hispanics, increasing 83% from 2003 to 2011 (P < .001). A greater increase in ADHD was also observed among females (55%, P < .001) than among males (40%). Economics, family status, non-English language in the home, and neighborhood safety factors differentially impacted diagnosed ADHD across racial/ethnic groups. Although new insights into the role of economic, family

Srinivas, Nisha; Rose, Derek C; Bolme, David S

This paper examines the difficulty associated with performing machine-based automatic demographic prediction on a sub-population of Asian faces. We introduce the Wild East Asian Face dataset (WEAFD), a new and unique dataset to the research community. This dataset consists primarily of labeled face images of individuals from East Asian countries, including Vietnam, Burma, Thailand, China, Korea, Japan, Indonesia, and Malaysia. East Asian turk annotators were uniquely used to judge the age and fine grain ethnicity attributes to reduce the impact of the other race effect and improve quality of annotations. We focus on predicting age, gender and fine-grained ethnicity ofmore » an individual by providing baseline results with a convolutional neural network (CNN). Finegrained ethnicity prediction refers to predicting ethnicity of an individual by country or sub-region (Chinese, Japanese, Korean, etc.) of the East Asian continent. Performance for two CNN architectures is presented, highlighting the difficulty of these tasks and showcasing potential design considerations that ease network optimization by promoting region based feature extraction.« less

Ambulatory blood pressure (BP) measurements of 120 female teachers of Japanese-American or Caucasian ethnicity working in public schools located in Hilo, Hawaii, were recorded. BP was measured at 15-min intervals during waking hours and 30-min intervals during sleep over a 24-hr period that included a full work day. These measurements were averaged during three daily settings: at work, at home while awake ("home"), and during sleep. ANCOVAs using ethnicity as a predictor variable of BP, with age and the body mass index (BMI) as covariates, show a significant interaction effect between age and ethnicity in some daily settings. Among Japanese-Americans partial correlations between age and systolic BP controlling for the BMI are significant in these settings, while among Caucasians none of the correlations are significant. Menopausal status is not significantly related to BP when age is controlled in analyses. There was no significant ethnic difference in number of symptoms reported, including frequency of "hot flushes/flashes," within the past two weeks. Those who reported hot flushes had significantly elevated BP in waking settings but not during sleep. The greater increase in BP with age in Japanese-Americans may be related to their elevated risk for development of hypertension. The lack of a significant relationship between menopausal status and BP may be due to the high rate of usage of hormonal replacement therapy in this sample, as well as an unusually high rate of hysterectomy.

Routine Eye Examinations for Persons 20-64 Years of Age

PubMed Central

2006-01-01

Executive Summary Objective The objective of this analysis was to determine the strength of association between age, gender, ethnicity, family history of disease and refractive error and the risk of developing glaucoma or ARM? Clinical Need A routine eye exam serves a primary, secondary, and tertiary care role. In a primary care role, it allows contact with a doctor who can provide advice about eye care, which may reduce the incidence of eye disease and injury. In a secondary care role, it can via a case finding approach, diagnose persons with degenerative eye diseases such as glaucoma and or AMD, and lead to earlier treatment to slow the progression of the disease. Finally in a tertiary care role, it provides ongoing monitoring and treatment to those with diseases associated with vision loss. Glaucoma is a progressive degenerative disease of the optic nerve, which causes gradual loss of peripheral (side) vision, and in advanced disease states loss of central vision. Blindness may results if glaucoma is not diagnosed and managed. The prevalence of primary open angle glaucoma (POAG) ranges from 1.1% to 3.0% in Western populations, and from 4.2% to 8.8% in populations of African descent. It is estimated up to 50% of people with glaucoma are aware that they have the disease. In Canada, glaucoma disease is the second leading cause of blindness in people aged 50 years and older. Tonometry, inspection of the optic disc and perimetry are used concurrently by physicians and optometrists to make the diagnosis of glaucoma. In general, the evidence shows that treating people with increased IOP only, increased IOP and clinical signs of early glaucoma or with normal-tension glaucoma can reduce the progression of disease. Age-related maculopathy (ARM) is a degenerative disease of the macula, which is a part of the retina. Damage to the macula causes loss of central vision affecting the ability to read, recognize faces and to move about freely. ARM can be divided into an early

Objectives Our objective was to augment the limited evidence mainly from local, clinical studies of ethnic differences in gastrointestinal disorders. Our question was: are there ethnic variations in hospitalisation/death for lower gastrointestinal disorders in Scotland? Setting Scotland. Population This retrospective-cohort linked 4.65 (of 4.9) million people in the 2001 census of Scotland (providing data on ethnicity, country of birth and indicators of socioeconomic deprivation) to 9 years of National Health Service hospitalisation and death records. Primary and secondary outcome measures and analysis For appendicitis, we studied all ages; for irritable bowel syndrome, ulcerative colitis, Crohn's disease and diverticular disease, we included those ≥20 years. Using Poisson regression (robust variance) we calculated, by ethnic group and sex, first-hospitalisation/death age-adjusted rates per 100 000 person-years, and relative risks (RRs) with 95% CIs multiplied by 100, so the White Scottish reference population had an RR=100. Results There were ethnic variations; for example, for irritable bowel syndrome, RRs (95% CIs) were comparatively high in Other White British women (128.4 (111.0 to 148.6)), and low in Pakistani women (75.1 (60.6 to 93.1)). For appendicitis, RRs were high in men in Other White British (145.2 (127.8 to 164.9)), and low in most non-White groups, for example, Pakistanis (73.8 (56.9 to 95.6)). For ulcerative colitis, RRs were high in Indian (169.8 (109.7 to 262.7)) and Pakistani (160.8 (104.2 to 248.2)) men. For Crohn's disease, the RR was high in Pakistani men (209.2 (149.6 to 292.6)). For diverticular disease, RRs were high in Irish men (176.0 (156.9 to 197.5)), and any Mixed background women (144.6 (107.4 to 194.8)), and low in most non-White groups, for example, Chinese men (47.1 (31.0 to 71.6) and women (46.0 (30.4 to 69.8)). Conclusions Appendicitis and diverticular disease were comparatively low in most non-White groups, while

Race/ethnicity has been shown to modify the effects between obesity and cancer screening among women. The purpose of this article is to update the literature with recent data to examine how the association between different characteristics, including body mass index (BMI), and cancer screening compliance varies by race/ethnicity in a national sample of women. Three cycles of the Health Information National Trends Survey (HINTS) were combined for this cross-sectional study. Weighted descriptive statistics were evaluated using chi-square tests. Multivariable logistic regression evaluated associations between women with underweight or normal (<25), overweight (25-29.9), and obese (>30) BMIs and cancer screening concordant with guidelines (Papanicolaou [Pap] testing ≤3 years, ages 21+ years; mammography ≤2 years, ages 40+ years) in analyses stratified by race/ethnicity. We also assessed variance between racial/ethnic groups in how age, income, and insurance status were associated with cancer screening compliance. This study included 4992 women who were evaluated for Pap testing and 3773 for mammography. In analyses stratified by race/ethnicity, whites with a higher household income were more likely to report having a Pap test (adjusted prevalence ratio [aPR] 2.16, 95% confidence interval [95% CI] 1.38-3.40) and a mammogram (aPR 1.63, 95% CI 1.04-2.55) compared to lower income white women. Black women with BMIs between 25 and 30 were less likely to receive a Pap test (aPR 0.38, 95% CI 0.19-0.76) than black women with BMIs <25, while no association was observed among the other groups. Insurance was associated with increased likelihood of Pap testing among white and black women. Insurance coverage was positively associated with mammography only among white and Hispanic women. We found variations in adherence to cancer screening guidelines by age, insurance coverage, and income between racial/ethnic groups. Little evidence was observed for variations in screening by

Objective To describe national trends in discretionary calories from sugar sweetened beverage (SSB) and snacks by age-specific body weight categories and by age- and weight-specific race/ethnicity groups. Examining these sub-populations is important as population averages may mask important differences. Design and Methods We used 24-hour dietary recall data obtained from the National Health and Nutrition Examination Survey 2003–2010 among children aged 2 to 19 (N=14,092). Logistic and linear regression methods were used to adjust for multiple covariates and survey design. Results The number of calories from SSBs declined significantly for nearly all age-specific body weight groups. Among overweight or obese children, significant declines in the number of calories from SSBs were observed among Hispanic children aged 2 to 5 (117 kcal vs. 174 kcal) and white adolescents aged 12 to 19 (299 kcal vs. 365 kcal). Significant declines in the number of calories from salty snacks were observed among white children aged 2 to 5 (192 kcal to 134 kcal) and 6 to 11 (273 kcal vs. 200 kcal). Conclusions The decrease in SSB consumption and increase in snack consumption observed in prior research are not uniform when children are examined within sub-groups accounting for age, weight and race/ethnicity.

Wilson, Antoinette R; Leaper, Campbell

2016-08-01

The purpose of this study was to integrate and validate a multidimensional model of ethnic-racial identity and gender identity borrowing constructs and measures based on social identity and gender identity theories. Participants included 662 emerging adults (M age  = 19.86 years; 75 % female) who self-identified either as Asian American, Latino/a, or White European American. We assessed the following facets separately for ethnic-racial identity and gender identity: centrality, in-group affect, in-group ties, self-perceived typicality, and felt conformity pressure. Within each identity domain (gender or ethnicity/race), the five dimensions generally indicated small-to-moderate correlations with one another. Also, correlations between domains for each dimension (e.g., gender typicality and ethnic-racial typicality) were mostly moderate in magnitude. We also noted some group variations based on participants' ethnicity/race and gender in how strongly particular dimensions were associated with self-esteem. Finally, participants who scored positively on identity dimensions for both gender and ethnic-racial domains indicated higher self-esteem than those who scored high in only one domain or low in both domains. We recommend the application of multidimensional models to study social identities in multiple domains as they may relate to various outcomes during development.

Few studies have focused on the simultaneous measurement of the friction and electrical properties of skin. This work investigates the feasibility of using these measurements to differentiate between the effects of chemicals commonly applied to the skin. In addition, this study also compares the condition of the skin and its response to application of chemicals across gender, ethnicity, and age at the volar forearm. Friction and electrical tests were performed on 59 healthy volunteers with the UMT Series Micro-Tribometer (UMT). A 13-mm-diameter copper cylindrical friction/electrical probe was pressed onto the skin with a weight of 20 g and moved across the skin at a constant velocity of 0.4 mm/s. Each volunteer served as his or her own control. The friction and electrical impedance measurements were performed for polyvinylidene chloride occlusion and for the application of glycerin and petrolatum. No differences were found across age, gender, or ethnicity at the volar forearm. Polyvinylidene chloride (PVDC) occlusion showed a small increase in the friction and a small decrease in the electrical impedance; petrolatum increased the friction by a greater amount but its effect on the impedance was comparable to PVDC occlusion; glycerin increased the friction by an amount comparable to petrolatum, but it decreased the impedance to a much greater degree than petrolatum or the PVDC occlusion. An amplitude/mean measurement of the friction curves of glycerin and petrolatum showed that glycerin has a significantly higher amplitude/mean than petrolatum. The properties of the volar forearm appear to be independent of age, gender, and ethnicity. Also, the simultaneous measurement of friction and electrical impedance was useful in differentiating between compounds administered to the skin.

Understanding How Race/Ethnicity and Gender Define Age-Trajectories of Disability: An Intersectionality Approach

PubMed Central

Warner, David F.; Brown, Tyson H.

2011-01-01

A number of studies have demonstrated wide disparities in health among racial/ethnic groups and by gender, yet few have examined how race/ethnicity and gender intersect or combine to affect the health of older adults. The tendency of prior research to treat race/ethnicity and gender separately has potentially obscured important differences in how health is produced and maintained, undermining efforts to eliminate health disparities. The current study extends previous research by taking an intersectionality approach (Mullings & Schulz, 2006), grounded in life course theory, conceptualizing and modeling trajectories of functional limitations as dynamic life course processes that are jointly and simultaneously defined by race/ethnicity and gender. Data from the nationally representative 1994–2006 US Health and Retirement Study and growth curve models are utilized to examine racial/ethnic/gender differences in intra-individual change in functional limitations among White, Black and Mexican American Men and Women, and the extent to which differences in life course capital account for group disparities in initial health status and rates of change with age. Results support an intersectionality approach, with all demographic groups exhibiting worse functional limitation trajectories than White Men. Whereas White Men had the lowest disability levels at baseline, White Women and racial/ethnic minority Men had intermediate disability levels and Black and Hispanic Women had the highest disability levels. These health disparities remained stable with age—except among Black Women who experience a trajectory of accelerated disablement. Dissimilar early life social origins, adult socioeconomic status, marital status, and health behaviors explain the racial/ethnic disparities in functional limitations among Men but only partially explain the disparities among Women. Net of controls for life course capital, Women of all racial/ethnic groups have higher levels of functional

Measuring the effect of ethnic and non-ethnic discrimination on Europeans' self-rated health.

PubMed

Alvarez-Galvez, Javier

2016-04-01

The study of perceived discrimination based on race and ethnic traits belongs to a long-held tradition in this field, but recent studies have found that non-ethnic discrimination based on factors such as gender, disability or age is also a crucial predictor of health outcomes. Using data from the European Social Survey (2010), and applying Boolean Factor Analysis and Ordered Logistic Regression models, this study is aimed to compare how ethnic and non-ethnic types of discrimination might affect self-rated health in the European context. We found that non-ethnic types of discrimination produce stronger differences on health outcomes. This result indicates that the probabilities of presenting a poor state of health are significantly higher when individuals feel they are being discriminated against for social or demographic conditions (gender, age, sexuality or disability) rather than for ethnic reasons (nationality, race, ethnicity, language or religiosity). This study offers a clear comparison of health inequalities based on ethnic and non-ethnic types of discrimination in the European context, overcoming analytical based on binary indicators and simple measures of discrimination.

Ethnic discrimination and health: the relationship between experienced ethnic discrimination and multiple health domains in Norway's rural Sami population.

Self-reported ethnic discrimination has been associated with a range of health outcomes. This study builds on previous efforts to investigate the prevalence of self-reported ethnic discrimination in the indigenous (Sami) population, and how such discrimination may be associated with key health indicators. The study relies on data from the 2003/2004 (n=4,389) population-based study of adults (aged 36-79 years) in 24 rural municipalities of Central and North Norway (the SAMINOR study). Self-reported ethnic discrimination was measured using the question: "Have you ever experienced discrimination due to your ethnic background?" Health indicators included questions regarding cardiovascular disease, diabetes, chronic muscle pain, metabolic syndrome and obesity. Logistic regression was applied to examine the relationship between self-reported ethnic discrimination and health outcomes. The study finds that for Sami people living in minority areas, self-reported ethnic discrimination is associated with all the negative health indicators included in the study. We conclude that ethnic discrimination affects a wide range of health outcomes. Our findings highlight the importance of ensuring freedom from discrimination for the Sami people of Norway.

Objectives. We aim to develop robust estimates of disability-free life expectancy (DFLE) and healthy life expectancy (HLE) for ethnic groups in England and Wales in 2001 and to examine observed variations across ethnic groups. Design. DFLE and HLE by age and gender for five-year age groups were computed for 16 ethnic groups by combining the 2001 Census data on ethnicity, self-reported limiting long-term illness and self-rated health using mortality by ethnic group estimated by two methods: the Standardised Illness Ratio (SIR) method and the Geographically Weighted Method (GWM). Results. The SIR and GWM methods differed somewhat in their estimates of life expectancy (LE) at birth but produced very similar estimates of DFLE and HLE by ethnic group. For the more conservative method (GWM), the range in DFLE at birth was 10.5 years for men and 11.9 years for women, double that in LE. DFLE at birth was highest for Chinese men (64.7 years, 95% CI 64.0–65.3) and women (67.0 years, 95% CI 66.4–67.6). Over half of the ethnic minority groups (men: 10; women: 9) had significantly lower DFLE at birth than White British men (61.7 years, 95% CI 61.7–61.7) or women (64.1 years, 95% CI 64.1–64.2), mostly the Black, Asian and mixed ethnic groups. The lowest DFLE observed was for Bangladeshi men (54.3 years, 95% CI 53.7–54.8) and Pakistani women (55.1 years, 95% CI 54.8–55.4). Notable were Indian women whose LE was similar to White British women but who had 4.3 years less disability-free (95% CI 4.0–4.6). Conclusions. Inequalities in DFLE between ethnic groups are large and exceed those in LE. Moreover, certain ethnic groups have a larger burden of disability that does not seem to be associated with shorter LE. With the increasing population of the non-White British community, it is essential to be able to identify the ethnic groups at higher risk of disability, in order to target appropriate interventions.

Objectives. We examined sexual orientation status differences in alcohol use among youths aged 13 to 18 years or older, and whether differences were moderated by sex, age, or race/ethnicity. Methods. We pooled data from the 2005 and 2007 Youth Risk Behavior Surveys and conducted weighted analyses, adjusting for complex design effects. We operationalized sexual orientation status with items assessing sexual orientation identity, sexual behavior, sexual attraction, or combinations of these. Results. Compared with exclusively heterosexual youths, sexual-minority youths were more likely to report each of the primary study outcomes (i.e., lifetime and past-month alcohol use, past-month heavy episodic drinking, earlier onset of drinking, and more frequent past-month drinking). Alcohol-use disparities were larger and more robust for (1) bisexual youths than lesbian or gay youths, (2) girls than boys, and (3) younger than older youths. Few differences in outcomes were moderated by race/ethnicity. Conclusions. Bisexual youths, sexual-minority girls, and younger sexual-minority youths showed the largest alcohol-use disparities. Research is needed that focuses on identifying explanatory or mediating mechanisms, psychiatric or mental health comorbidities, and long-term consequences of early onset alcohol use, particularly frequent or heavy use, among sexual-minority youths.

Those sharing cross-cultural patterns (sexism, ageism) each combine societal status differences and intimate interdependence. For example, in stereotypes of sex and age, lower status groups-women and elders-gain stereotypic warmth (from their cooperative interdependence) but lose stereotypic competence (from their lower status); men and middle-aged adults show the opposite trade-off, stereotypically more competent than warm. Meta-analyses support these widespread ambivalent (mixed) stereotypes for gender and age across cultures. Social class stereotypes often share some similarities (cold but competent rich vs. warm but incompetent poor). These compensatory warmth versus competence stereotypes may function to manage common human dilemmas of interacting across societal and personal positions. However, other stereotypes are more variable and culture specific (ethnicity, race, religion). Case studies of specific race/ethnicities and religions reveal much more cultural variation in their stereotype content, supporting their being responses to particular cultural contexts, apparent accidents of history. To change stereotypes requires understanding their commonalities and differences, their origins and patterns across cultures.

We examined which specific foods contributed to the atherogenic potential of diet in population segments defined by age, sex, educational attainment, and race/ethnicity. Data from the 1989 New York State Healthy Heart Program baseline survey were analyzed. This telephone survey was conducted in eight communities (total population approximately 1.24 million people) in New York State. Response rate was 65.5% (N = 4,179); 3,606 subjects ages 20 to 64 years who reported their level of educational attainment with self-described ethnicity of white (N = 1,935), black (N = 1,035), or Hispanic (N = 636) were retained in the analysis. Diet was assessed using a 17-item food frequency questionnaire which focused on commonly eaten food high in saturated fat and cholesterol. Connor's cholesterol/saturated-fat index was used as a scale of the atherogenic potential of the diet. Eggs, whole milk, cheese, beef, and butter/margarine were the foods contributing most to the cholesterol/saturated-fat index score in all age-, sex-, and race/ethnicity-specific population segments examined, together contributing a total of 52 to 72% of the cholesterol/saturated-fat index score as measured by the 17-item diet questionnaire. The implication for public health campaigns directed at reducing the atherogenic potential of diet atherogenicity and for primary care practitioners seeking to influence the diet of patients with high blood cholesterol is that substitutions of less atherogenic food choices for these five foods would appear to be appropriate for most adults.

To explore ethnic inequalities in periodontal disease among British adults, and the role of socioeconomic position (SEP) in those inequalities. We analysed data on 1925 adults aged 16-65 years, from the East London Oral Health Inequality (ELOHI) Study, which included a random sample of adults living in an ethnically diverse and socially deprived area. Participants completed a questionnaire and were clinically examined for the number of teeth with periodontal pocket depth (PPD)≥4 mm and loss of attachment (LOA)≥4 mm. Ethnic inequalities in periodontal measures were assessed in negative binomial regression models before and after adjustment for demographic (gender and age groups) and SEP indicators (education and socioeconomic classification). Compared to White British, Pakistani, Indian, Bangladeshi and Asian Others had more teeth with PPD≥4 mm whereas White East European, Black African and Bangladeshi had more teeth with LOA≥4 mm, after adjustments for demographic and SEP measures. The association of ethnicity with periodontal disease was moderated by education, but not by socioeconomic classification. Stratified analysis showed that ethnic disparities in the two periodontal measures were limited to more educated groups. This study showed considerable ethnic disparities in periodontal disease between and within the major ethnic categories. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

growth is a remarkable index of health and can be influenced by genetic and environment conditions. The pattern of growth is unique for every nation and worldwide studies have demonstrated separate national standards. In the case of Iran, there is not enough information in this field. This study was undertaken on 7-12 years old children from Arak. The data for each individual such as age, height, weight and body mass index (BMI) were recorded. Differences in the data between two sexes were tested by means of the paired sample t- test and the mean BMI was compared with sex- and age-specific reference values from the National Center for Health Statistics of the Centers for Disease Control (CDC) 2000 growth chart using independent sample t-tests. Levels of P < 0.05, P < 0.01 and P < 0.001 were recorded as significant. In this study, males were significantly taller and heavier than females at the same age (P < or = 0.01) except for length at age 10 and weight at age 12. The BMI curves were between 50th and 25th percentiles of CDC. The present study shows the effect of socioeconomic background that had been also considered in other studies in Iran. There is a need for ethnic specific growth charts and BMI cut-off points for underweight, overweight and obesity in children of each ethnic subgroup of Iranian population.

Introduction Ethnic differences in the birth prevalence of congenital heart defects (CHDs) have been reported; however, studies of the contemporary UK population are lacking. We investigated ethnic variations in incidence of serious CHDs requiring cardiac intervention before 1 year of age. Methods All infants who had a cardiac intervention in England and Wales between 1 January 2005 and 31 December 2010 were identified in the national congenital heart disease surgical audit and matched with paediatric intensive care admission records to create linked individual child records. Agreement in reporting of ethnic group by each audit was evaluated. For infants born 1 January 2006 to 31 December 2009, we calculated incidence rate ratios (IRRs) for CHDs by ethnicity and investigated age at intervention, antenatal diagnosis and area deprivation. Results We identified 5350 infants (2940 (55.0%) boys). Overall CHD incidence was significantly higher in Asian and Black ethnic groups compared with the White reference population (incidence rate ratios (IRR) (95% CIs): Asian 1.5 (1.4 to 1.7); Black 1.4 (1.3 to 1.6)); incidence of specific CHDs varied by ethnicity. No significant differences in age at intervention or antenatal diagnosis rates were identified but affected children from non-White ethnic groups were more likely to be living in deprived areas than White children. Conclusions Significant ethnic variations exist in the incidence of CHDs, including for specific defects with high infant mortality. It is essential that healthcare provision mitigates ethnic disparity, including through timely identification of CHDs at screening, supporting parental choice and effective interventions. Future research should explore the factors underlying ethnic variation and impact on longer-term outcomes. PMID:27986699

Pancytopenia is a recognisable haematological problem with common categorises diagnosis but best possible diagnostic approach is still to be defined. The aim of this study was to determine the frequent causes and clinical presentation of pancytopenia in relation to age and sex in different ethnic groups of two national (Pakistani and Afghan) living in Baluchistan province. This is a cross sectional descriptive type of study was carried out on patients (n = 180) for two years (July 2009-June 2011). Cases were successively registered in 2 provincial government hospital and 2 private clinics in Quetta with diagnosis of pancytopenia. The most frequent causes of pancytopenia in both national ethnic groups were malaria (29.44%) fallowed by tuberculosis (17.22%), leukaemia (16.67%), aplastic anaemia (13.33%), hepatitis (12.22%), other diseases (7.22%) and iron deficiency anaemia (3.89%). Overall, 63.89% male subjects were observed pancytopenia as compared to 36.11% female patients. The results also showed that patients with age > 41 years were highly (50%) affected by pancytopenia followed by 21-40 years (30.66%) and < 20 years (19.44%). Moreover, leukaemia cases were observed significantly higher in Afghan subjects (> 41 years). The most common symptom of patients was (71.11%) fever followed by Pallor (42.22%), fatigue (38.33%), weight loss (26.11%) and dizziness (25.56%). Leukaemia and aplastic anaemia were found to be the most serious causes of pancytopenia in Afghan ethnic group. Malaria, tuberculosis, aplastic anaemia, and leukaemia were the leading causes of pancytopenia in Pakistani and Afghan ethnic groups. Severe pancytopenia has significant relation with the clinical conclusion and can be used as a prognostic marker.

The objective of this study is to examine longevity disparities in Hawai‘i by race/ethnicity and gender based on age-specific death rates in 2010. Abridged life tables for Chinese, Japanese, Filipino, Hawaiians, and Caucasians in Hawai‘i are presented for the age groups: <1, 1–4, every 5-year interval from 5–84, and 85+ years for the year of 2010. Death data were provided by the Hawai‘i Department of Health Office of Health Status Monitoring, and population data were based on 2010 Census modified based on ethnicity estimates from the Hawai‘i Health Survey. Life expectancy at birth in Hawai‘i has increased consistently from 69.5 years in 1950 to 82.4 years in 2010. Longevity disparities seen in past decades continue to persist between the longest-living groups, Japanese and Chinese, and the shortest-living group, Native Hawaiians, with a gap of approximately 10 years. In addition, females lived 6 years longer than males on average. Racial/ethnic disparities in longevity can be partially explained by differences in socioeconomic status, health behaviors, health care access, and racism. Native Hawaiians continue to have the shortest life expectancy of the ethnic groups examined, requiring expanded efforts to address Native Hawaiian health across the life course. Our findings also support more ethnic-specific research to understand the health care needs and utilization patterns of each group. PMID:28090398

Our objective was to describe racial and ethnic differences of amyotrophic lateral sclerosis (ALS) in distinct geographic locations around the United States (U.S.). ALS cases for the period 2009-2011 were identified using active case surveillance in three states and eight metropolitan areas. Of the 5883 unique ALS cases identified, 74.8% were white, 9.3% were African-American/black, 3.6% were Asian, 12.0% were an unknown race, and 0.3% were marked as some other race. For ethnicity, 77.5% were defined as non-Hispanic, 10.8% Hispanic, and 11.7% were of unknown ethnicity. The overall crude average annual incidence rate was 1.52 per 100,000 person-years and the rate differed by race and ethnicity. The overall age-adjusted average annual incidence rate was 1.44 per 100,000 person-years and the age-adjusted average incidence rates also differed by race and ethnicity. Racial differences were also found in payer type, time from symptom onset to diagnosis, reported El Escorial criteria, and age at diagnosis. In conclusion, calculated incidence rates demonstrate that ALS occurs less frequently in African-American/blacks and Asians compared to whites, and less frequently in Hispanics compared to non-Hispanics in the U.S. A more precise understanding of racial and ethnic variations in ALS may help to reveal candidates for further studies of disease etiology and disease progression.

Latin American women present more severe menopausal symptoms when compared to those from other regions of the world. Since this population is an ethnic blend of Caucasian and indigenous people, we sought to test the hypothesis that severe menopausal symptoms in Latin American women are associated with an indigenous origin. To assess menopausal symptoms among two specific indigenous Latin American populations. A total of 573 natural postmenopausal indigenous women aged 45-59 years (288 Quechua (Peru) and 285 Zenú (Colombia)) living in isolated communities were surveyed with a general questionnaire and the Menopause Rating Scale (MRS). The total MRS score was significantly higher among Quechua women as compared to Zenú ones (22.7 ± 5.7 vs. 14.7 ± 2.5, p < 0.0001); both figures were higher than those described for Hispanic or European populations. Quechua women presented more intense somatic and psychological symptoms as compared to Zenú (8.8 ± 2.3 vs. 5.3 ± 1.8; and 7.8 ± 2.4 vs. 3.2 ± 1.7, p < 0.0001); however, both indigenous groups presented similar intense urogenital symptoms (6.1 ± 1.6 vs. 6.2 ± 1.4, not significant). These differences persisted after adjusting for age, years since menopause onset and parity. The percentage of women presenting severe somatic and psychological symptoms significantly increased with aging among Quechua. This was not the case for Zenú women. More than 90% of indigenous women (Quechua and Zenú) at all age intervals presented severe urogenital scores, a percentage that is much higher than that described in the world literature. Severe menopausal symptoms found among Latin American women could be the result of their indigenous ethnic origin; the urogenital domain is the most affected.

Although nearly 112 million residents of the United States belong to a non-white ethnic group, the literature about differences in health indicators across ethnic groups is limited almost exclusively to Hispanics. Features of the social experience of many ethnic groups including immigration, discrimination, and acculturation may plausibly influence mortality risk. We explored life expectancy and age-adjusted mortality risk of Arab-Americans (AAs), relative to non-Arab and non-Hispanic Whites in Michigan, the state with the largest per capita population of AAs in the US. Data were collected about all deaths to AAs and non-Arab and non-Hispanic Whites in Michigan between 1990 and 2007, and year 2000 census data were collected for population denominators. We calculated life expectancy, age-adjusted all-cause, cause-specific, and age-specific mortality rates stratified by ethnicity and gender among AAs and non-Arab and non-Hispanic Whites. Among AAs, life expectancies among men and women were 2.0 and 1.4 years lower than among non-Arab and non-Hispanic White men and women, respectively. AA men had higher mortality than non-Arab and non-Hispanic White men due to infectious diseases, chronic diseases, and homicide. AA women had higher mortality than non-Arab and non-Hispanic White women due to chronic diseases. Despite better education and higher income, AAs have higher age-adjusted mortality risk than non-Arab and non-Hispanic Whites, particularly due to chronic diseases. Features specific to AA culture may explain some of these findings. © 2011 El-Sayed et al.

Objectives Biological modelling of routinely collected newborn screening data has emerged as a novel method for deriving postnatal gestational age estimates. Validation of published models has previously been limited to cohorts largely consisting of infants of white Caucasian ethnicity. In this study, we sought to determine the validity of a published gestational age estimation algorithm among recent immigrants to Canada, where maternal landed immigrant status was used as a surrogate measure of infant ethnicity. Design We conducted a retrospective validation study in infants born in Ontario between April 2009 and September 2011. Setting Provincial data from Ontario, Canada were obtained from the Institute for Clinical Evaluative Sciences. Participants The dataset included 230 034 infants born to non-landed immigrants and 70 098 infants born to immigrant mothers. The five most common countries of maternal origin were India (n=10 038), China (n=7468), Pakistan (n=5824), The Philippines (n=5441) and Vietnam (n=1408). Maternal country of origin was obtained from Citizenship and Immigration Canada’s Landed Immigrant Database. Primary and secondary outcome measures Performance of a postnatal gestational age algorithm was evaluated across non-immigrant and immigrant populations. Results Root mean squared error (RMSE) of 1.05 weeks was observed for infants born to non-immigrant mothers, whereas RMSE ranged from 0.98 to 1.15 weeks among infants born to immigrant mothers. Area under the receiver operating characteristic curve for distinguishing term versus preterm infants (≥37 vs <37 weeks gestational age or >34 vs ≤34 weeks gestational age) was 0.958 and 0.986, respectively, in the non-immigrant subgroup and ranged from 0.927 to 0.964 and 0.966 to 0.99 in the immigrant subgroups. Conclusions Algorithms for postnatal determination of gestational age may be further refined by development and validation of region or ethnicity-specific models. However, our

Understanding determinants of high consumption of sugar-sweetened beverages (SSBs), a highly prevalent obesogenic behavior, will help build effective customized public health interventions. Our aim was to identify child and parent lifestyle and household demographic factors predictive of high SSB consumption frequency in children from low-income, ethnically diverse communities that may help inform public health interventions. We used a cross-sectional telephone household survey. Participants were 717 boys and 686 girls aged 3 to 18 years old from the New Jersey Childhood Obesity Study living in five low-income cities (Camden, New Brunswick, Newark, Trenton, and Vineland). The adult most knowledgeable about household food shopping completed a questionnaire over the telephone inquiring about their and their child's dietary and physical activity habits, and household-, parent-, and child-level demographics. Child's SSB consumption frequency was measured. Multivariate ordered logit models were designed to investigate a variety of variables hypothesized to affect the frequency of SSB consumption. Exploratory stratified analyses by race, sex, and age were also conducted. Eight percent of our study participants never consumed SSBs, 45% consumed SSBs at least once per day, and 23% consumed twice or more per day. SSB consumption was higher among children 12 to 18 years vs 3 to 5 years (P<0.0001), of non-Hispanic black vs non-Hispanic white race/ethnicity (P=0.010), who were moderate fast food consumers vs never consumers (P=0.003), and those whose parents were high vs low SSB consumers (P<0.0001). Living in a non-English-speaking household (P=0.030), having a parent with a college or higher education vs less than high school (P=0.003), and having breakfast 6 to 7 days/wk vs never to 2 days/wk or less were associated with lower SSB consumption (P=0.001). We identified a number of household-, parent-, and child-level predictors of SSB consumption, which varied by race, sex

It is unclear whether cultural differences or material disadvantage explain the ethnic patterning of obesogenic behaviours. The aim of this study was to examine ethnicity as a predictor of obesity-related behaviours among children in England, and to assess whether the effects of ethnicity could be explained by deprivation. Five primary care trusts in England, 2010-2011. Parents of white, black and South Asian children aged 4-5 and 10-11 years participating in the National Child Measurement Programme (n=2773). Parent-reported measures of child behaviour: low level of physical activity, excessive screen time, unhealthy dietary behaviours and obesogenic lifestyle (combination of all three obesity-related behaviours). Associations between these behaviours and ethnicity were assessed using logistic regression analyses. South Asian ethnic groups made up 22% of the sample, black ethnic groups made up 8%. Compared with white children, higher proportions of Asian and black children were overweight or obese (21-27% vs16% of white children), lived in the most deprived areas (24-47% vs 14%) and reported obesity-related behaviours (38% with obesogenic lifestyle vs 16%). After adjusting for deprivation and other sociodemographic characteristics, black and Asian children were three times more likely to have an obesogenic lifestyle than white children (OR 3.0, 95% CI 2.1 to 4.2 for Asian children; OR 3.4, 95% CI 2.7 to 4.3 for black children). Children from Asian and black ethnic groups are more likely to have obesogenic lifestyles than their white peers. These differences are not explained by deprivation. Culturally specific lifestyle interventions may be required to reduce obesity-related health inequalities.

Age and ethnic differences in cold weather and contagion theories of colds and flu.

Sigelman, Carol K

2012-02-01

Age and ethnic group differences in cold weather and contagion or germ theories of infectious disease were explored in two studies. A cold weather theory was frequently invoked to explain colds and to a lesser extent flu but became less prominent with age as children gained command of a germ theory of disease. Explanations of how contact with other people causes disease were more causally sophisticated than explanations of how cold weather causes it. Finally, Mexican American and other minority children were more likely than European American children to subscribe to cold weather theories, a difference partially but not wholly attributable to ethnic group differences in parent education. Findings support the value of an intuitive or naïve theories perspective in understanding developmental and sociocultural differences in concepts of disease and in planning health education to help both children and their parents shed misconceptions so that they can focus on effective preventive actions.

The study used cross-sectional data of 462 girls and 372 boys of Russian ethnicity and 90 Kalmyk girls 12-17-year-olds. In both groups children were examined by the same researchers according to the same research protocol. All of the observations have been performed in agreement with bioethical procedures; protocols of consent were filled either by the subject (elder children) or by his/her parent(s). Standing height, weight, body circumferences and skinfolds thickness were taken on each individual according to the standard technique. Body mass index (BMI) was calculated. In Arkhangelsk city 114 boys and 172 girls among the total number of studied subjects filled in the questionnaires, and in Elista – 34 girls among 90. Data sets were divided according to sex, age, somatotypes and ethnicity. The results of the present study showed significant correlations between somatotypes of the subjects, their BMI and self-estimation of their physical appearance. In self-perception of one’s body, weight was the most important characteristics in girls, while in boys it was stature. No differences were found in most of self-evaluation scores between Russian girls of Arkhangelsk city and Kalmyk girls of Elista, apart from the fact that the latter had lower scores in the estimation of their body shape, possibly because they were fatter. The strategies chosen by the adolescents for modifications of their bodies in their quest for »ideal« figures were in favor of dieting versus physical activity, which puts the question of popularization of physical culture and sports on a nation-wide scale.

Objective Self-reported ethnic discrimination has been associated with a range of health outcomes. This study builds on previous efforts to investigate the prevalence of self-reported ethnic discrimination in the indigenous (Sami) population, and how such discrimination may be associated with key health indicators. Study design The study relies on data from the 2003/2004 (n=4,389) population-based study of adults (aged 36–79 years) in 24 rural municipalities of Central and North Norway (the SAMINOR study). Self-reported ethnic discrimination was measured using the question: “Have you ever experienced discrimination due to your ethnic background?” Health indicators included questions regarding cardiovascular disease, diabetes, chronic muscle pain, metabolic syndrome and obesity. Logistic regression was applied to examine the relationship between self-reported ethnic discrimination and health outcomes. Results The study finds that for Sami people living in minority areas, self-reported ethnic discrimination is associated with all the negative health indicators included in the study. Conclusion We conclude that ethnic discrimination affects a wide range of health outcomes. Our findings highlight the importance of ensuring freedom from discrimination for the Sami people of Norway.

Previous studies documented significant increase in overall survival for metastatic colorectal cancer (CRC) since the late 1990s coinciding with the introduction and dissemination of new treatments. We examined whether this survival increase differed across major racial/ethnic populations and age groups. We identified patients diagnosed with primary metastatic colorectal cancer during 1992-2009 from 13 population-based cancer registries of the National Cancer Institute's Surveillance, Epidemiology, and End Results Program, which cover about 14 % of the US population. The 5-year cause-specific survival rates were calculated using SEER*Stat software. From 1992-1997 to 2004-2009, 5-year cause-specific survival rates increased significantly from 9.8 % (95 % CI 9.2-10.4) to 15.7 % (95 % CI 14.7-16.6) in non-Hispanic whites and from 11.4 % (95 % CI 9.4-13.6) to 17.7 % (95 % CI 15.1-20.5) in non-Hispanic Asians, but not in non-Hispanic blacks [from 8.6 % (95 % CI 7.2-10.1) to 9.8 % (95 % CI 8.1-11.8)] or Hispanics [from 14.0 % (95 % CI 11.8-16.3) to 16.4 % (95 % CI 14.0-19.0)]. By age group, survival rates increased significantly for the 20-64-year age group and 65 years or older age group in non-Hispanic whites, although the improvement in the older non-Hispanic whites was substantially smaller. Rates also increased in non-Hispanic Asians for the 20-64-year age group although marginally nonsignificant. In contrast, survival rates did not show significant increases in both younger and older age groups in non-Hispanic blacks and Hispanics. Non-Hispanic blacks, Hispanics, and older patients diagnosed with metastatic CRC have not equally benefitted from the introduction and dissemination of new treatments.

Our objective was to augment the limited evidence mainly from local, clinical studies of ethnic differences in gastrointestinal disorders. Our question was: are there ethnic variations in hospitalisation/death for lower gastrointestinal disorders in Scotland? Scotland. This retrospective-cohort linked 4.65 (of 4.9) million people in the 2001 census of Scotland (providing data on ethnicity, country of birth and indicators of socioeconomic deprivation) to 9 years of National Health Service hospitalisation and death records. For appendicitis, we studied all ages; for irritable bowel syndrome, ulcerative colitis, Crohn's disease and diverticular disease, we included those ≥20 years. Using Poisson regression (robust variance) we calculated, by ethnic group and sex, first-hospitalisation/death age-adjusted rates per 100,000 person-years, and relative risks (RRs) with 95% CIs multiplied by 100, so the White Scottish reference population had an RR=100. There were ethnic variations; for example, for irritable bowel syndrome, RRs (95% CIs) were comparatively high in Other White British women (128.4 (111.0 to 148.6)), and low in Pakistani women (75.1 (60.6 to 93.1)). For appendicitis, RRs were high in men in Other White British (145.2 (127.8 to 164.9)), and low in most non-White groups, for example, Pakistanis (73.8 (56.9 to 95.6)). For ulcerative colitis, RRs were high in Indian (169.8 (109.7 to 262.7)) and Pakistani (160.8 (104.2 to 248.2)) men. For Crohn's disease, the RR was high in Pakistani men (209.2 (149.6 to 292.6)). For diverticular disease, RRs were high in Irish men (176.0 (156.9 to 197.5)), and any Mixed background women (144.6 (107.4 to 194.8)), and low in most non-White groups, for example, Chinese men (47.1 (31.0 to 71.6) and women (46.0 (30.4 to 69.8)). Appendicitis and diverticular disease were comparatively low in most non-White groups, while ulcerative colitis and Crohn's disease were mostly higher in South Asians.

Presurgical psychological screening is used to identify factors that may impact postoperative adherence and surgical outcomes in bariatric surgery candidates. Minnesota Multiphasic Personality Inventory - 2 Restructured Form (MMPI-2-RF) findings have demonstrated utility for this task. To explore whether there are clinically meaningful gender, ethnicity, or age differences in presurgical MMPI-2-RF scores and the validity of these scores in bariatric surgery candidates. The sample was composed of 872 men and 2337 women. Ethnicity/race groups included 2,204 Caucasian, 744 African American, and 96 Hispanic individuals. A sample of 165 were not included in the ethnicity/race analyses because they were of another descent. Ages groups included 18-35 year olds (n = 454), 36-49 year olds (n = 1154), 50-64 year olds, (n = 1246), and 65 years old or older (n = 355). Validity data, obtained via a retrospective chart review, were available for a subset patients (n = 1,268) who were similarly distributed. Step-down hierarchical regression analyses were conducted to assess for differential validity. Bariatric surgery candidates produced comparable MMPI-2-RF scores in all subsamples, indicating that the test norms generalize across demographic groups. Validity findings were also generally comparable, indicating that MMPI-2-RF scores have the same interpretive implications in demographically diverse subgroups of bariatric surgery candidates. The MMPI-2-RF can assist in presurgical psychological screening of demographically diverse bariatric surgery candidates. Copyright © 2015 American Society for Bariatric Surgery.

This study examined the role of ethnicity on the aerobic fitness, blood pressure, and selected blood chemistry values of women. One hundred twenty-four females (mean age 41.37 +/- 9.0) were medically Examined at the NASA/Johnson Space Center occupational health clinic. Ethnic groups consisted of 23 Black (B), 18 Hispanic (H) and 83 Non-minority (NM). Each woman had a maximum Bruce treadmill stress test (RER greater than or = 1.1) and a negative ECG. Indirect calorimetry, skinfolds, self-report physical activity (NASA activity scale), seated blood pressure, and blood chemistry panel determined VO2max, percent fat, level of physical activity, blood pressure and blood chemistry values. ANOVA revealed that the groups did not differ (p greater than 0.05) in age, VO2 max, weight, percent fat, level of physical activity, total cholesterol, or HDL-C. However, significant differences (p greater than 0.05) were noted in BMI, diastolic blood pressure, and blood chemistries. BMI was 3.17 higher in H than in NM; resting diastolic pressures were 5.69 and 8.05 mmHg. lower in NM and H than in B; triglycerides were 48.07 and 37.21 mg/dl higher in H than in B and NM; hemoglobin was .814 gm/dl higher in NM than B; fasting blood sugar was 15.41 mg/dl higher in H than NM; The results of this study showed that ethnic groups differed in blood pressure and blood chemistry values but not aerobic fitness or physical activity. There was an ethnic difference in BMI but not percent fat.

Ethnic differences in the birth prevalence of congenital heart defects (CHDs) have been reported; however, studies of the contemporary UK population are lacking. We investigated ethnic variations in incidence of serious CHDs requiring cardiac intervention before 1 year of age. All infants who had a cardiac intervention in England and Wales between 1 January 2005 and 31 December 2010 were identified in the national congenital heart disease surgical audit and matched with paediatric intensive care admission records to create linked individual child records. Agreement in reporting of ethnic group by each audit was evaluated. For infants born 1 January 2006 to 31 December 2009, we calculated incidence rate ratios (IRRs) for CHDs by ethnicity and investigated age at intervention, antenatal diagnosis and area deprivation. We identified 5350 infants (2940 (55.0%) boys). Overall CHD incidence was significantly higher in Asian and Black ethnic groups compared with the White reference population (incidence rate ratios (IRR) (95% CIs): Asian 1.5 (1.4 to 1.7); Black 1.4 (1.3 to 1.6)); incidence of specific CHDs varied by ethnicity. No significant differences in age at intervention or antenatal diagnosis rates were identified but affected children from non-White ethnic groups were more likely to be living in deprived areas than White children. Significant ethnic variations exist in the incidence of CHDs, including for specific defects with high infant mortality. It is essential that healthcare provision mitigates ethnic disparity, including through timely identification of CHDs at screening, supporting parental choice and effective interventions. Future research should explore the factors underlying ethnic variation and impact on longer-term outcomes. Published by the BMJ Publishing Group Limited.

Cancer of the lung is the most frequent cancer in the world, but with wide geographical variation in risk. It is most spread among males of all races worldwide, the only exception being its incidence among Chinese women aged 70 years and older. When comparing the different ethnic groups we have to consider that besides inhaling cigarette smoke actively or as a passive smoker the exposure to occupational carcinogens varies considerably according to different work places. In our study we compared 10 years of data from African-Americans in Howard University Hospital, Washington D.C. with 20 years of data from the white population in the University Hospital of Vienna, Austria. Ethnic patterns are generally consistent within each group in terms of both incidence and mortality. The difference in susceptibility between the sexes, the three major racial groups and already proven differences in genetic variations indicate the difference between individuals concerning the initiation and progression of lung cancer.

The cause of ethnic differences in cardiovascular disease remains a scientific challenge. Blood pressure tracks from late childhood to adulthood. We examined ethnic differences in changes in blood pressure between early and late adolescence in the United Kingdom. Longitudinal measures of blood pressure, height, weight, leg length, smoking, and socioeconomic circumstances were obtained from London, United Kingdom, schoolchildren of White British (n=692), Black Caribbean (n=670), Black African (n=772), Indian (n=384), and Pakistani and Bangladeshi (n=402) ethnicity at 11 to 13 years and 14 to 16 years. Predicted age- and ethnic-specific means of blood pressure, adjusted for anthropometry and social exposures, were derived using mixed models. Among boys, systolic blood pressure did not differ by ethnicity at 12 years, but the greater increase among Black Africans than Whites led to higher systolic blood pressure at 16 years (+2.9 mm Hg). Among girls, ethnic differences in mean systolic blood pressure were not significant at any age, but while systolic blood pressure hardly changed with age among White girls, it increased among Black Caribbeans and Black Africans. Ethnic differences in diastolic blood pressure were more marked than those for systolic blood pressure. Body mass index, height, and leg length were independent predictors of blood pressure, with few ethnic-specific effects. Socioeconomic disadvantage had a disproportionate effect on blood pressure for girls in minority groups. The findings suggest that ethnic divergences in blood pressure begin in adolescence and are particularly striking for boys. They signal the need for early prevention of adverse cardiovascular disease risks in later life.

This study investigates intergeneration transmission of ethnic identity as a resource for life satisfaction of Roma adolescents and their parents. Historically, Roma represent the largest ethnic minority in Europe. They have been exposed to severe discrimination, social exclusion, and poverty. Therefore, identifying resources for their life satisfaction is theoretically and practically important. The present study included 1093 participants, of which there were 171 Roma adolescents (age: M = 14.96 years, SD = 1.85), 155 mothers (age: M = 36.16 years, SD = 5.77) and 123 fathers (age: M = 39.68 years, SD = 6.06). Further, a comparison group of 248 mainstream adolescents with their mothers (n = 221) and fathers (n = 175) was also included in the study. Adolescents and their parents provided data on ethnic identity (MEIM; Phinney, 1992) and life satisfaction (SWLS; Diener, Emmons, Larsen, & Griffin, 1985). Results indicated that Roma youth were lower on endorsement of ethnic identity and average on life satisfaction compared to their mainstream peers. A structural equation model showed that ethnic identity was a positive predictor of life satisfaction for both adolescents and their Roma parents. Furthermore, parents' ethnic identity was a predictor of adolescent life satisfaction. We concluded that for Roma youth and their parents, ethnic identity represents a salient source for life satisfaction and an intergenerational continuity of identity and life satisfaction exists.

Rahman, Saleh M M; Dignan, Mark B; Shelton, Brent J

2003-01-01

To explore patterns of adherence to guidelines for screening mammography among participants in the Colorado Mammography Project (CMAP) surveillance database. An algorithm was developed to assess factors associated with adherence to mammography screening guidelines. Of the 27,778 women ranging from 40-90 years of age included in the analysis, 41.4% were adherent with mammography screening guidelines. According to the model tested in this study, race/ethnicity (Black vs White, OR=0.76, 95% CI=0.64-0.91); educational attainment (high school vs 55,000 dollars vs <15,000 dollars, OR 1.14, 95% CI=1.03-1.26) were statistically significant predictors of adherence to guidelines. A significant interaction between age and family history of breast cancer (BC) was also found. Younger females with a family history of BC were less likely to be adherent than their counterparts without a family history (OR=0.93, 95% CI=0.90-0.96). In general, elderly women were more likely to be adherent compared with the youngest group in this cohort (OR=1.21, 95% CI=1.11-1.33). Inclusion or exclusion of women aged 70 years and older did not change the outcome of the analysis. Adherence with screening mammography guidelines was found to be associated with women's personal characteristics including race/ethnicity, age, and family history of BC. In addition, socioeconomic status, as measured by educational level and community economic status, are important predictors of adherence. Efforts to increase adherence may need to be specific to race/ethnic group and age, but the effect of age is mediated by family history of BC and vice versa.

Deaths from Falls Among Persons Aged ≥65 Years - United States, 2007-2016.

Deaths from unintentional injuries are the seventh leading cause of death among older adults (1), and falls account for the largest percentage of those deaths. Approximately one in four U.S. residents aged ≥65 years (older adults) report falling each year (2), and fall-related emergency department visits are estimated at approximately 3 million per year.* In 2016, a total of 29,668 U.S. residents aged ≥65 years died as the result of a fall (age-adjusted rate †  = 61.6 per 100,000), compared with 18,334 deaths (47.0) in 2007. To evaluate this increase, CDC produced age-adjusted rates and trends for deaths from falls among persons aged ≥65 years, by selected characteristics (sex, age group, race/ethnicity, and urban/rural status) and state from 2007 to 2016. The rate of deaths from falls increased in the United States by an average of 3.0% per year during 2007-2016, and the rate increased in 30 states and the District of Columbia (DC) during that period. In eight states, the rate of deaths from falls increased for a portion of the study period. The rate increased in almost every demographic category included in the analysis, with the largest increase per year among persons aged ≥85 years. Health care providers should be aware that deaths from falls are increasing nationally among older adults but that falls are preventable. Falls and fall prevention should be discussed during annual wellness visits, when health care providers can assess fall risk, educate patients about falls, and select appropriate interventions.

Contextual influences on ethnic identity formation: a case study of second-generation Korean Americans Baby Boomers in midlife.

This paper details a study on ethnic identity in midlife, illuminating identity formation as a complex life course phenomenon. The study addresses the importance of ethnic identity in understanding the experiences of racial and ethnic Baby Boomers as both recipients of care and as caregivers to their aging parents (first generation immigrants). Using a case study of second-generation Korean American Baby Boomers, the primary aims of this study are: (a) to explore how the relationship between age and race/ethnicity influences identity formation, and (b) how contexts influence ethnic identity formation. Findings reveal that cumulative experiences over earlier developmental years resulted in resolutions to appreciate their ethnic identity at midlife. Increasing racial and ethnic diversity in the U.S., combined with the large number of aging Baby Boomers, necessitate recognition of the cultural and racial differences within the Baby Boomer generation.

Improvements in environmental conditions may result in an earlier onset of thelarche. However, its onset is not homogeneous among different population groups. To assess the relationship between nutritional status, ethnicity and age of thelarche. Cross-sectional study of girls in second through sixth grade, attending 165 schools located in Chile's Araucania region. Of these, 231 girls who presented thelarche (breast button) were selected. The girls' surnames were used to identify their ethnicity: indigenous had three or four last names of Mapuche indigenous origin (n =113), while non-indigenous were those who only had Chilean-Spanish last names (n =118). Weight, height, waist circumference and skinfold thicknesses were measured and socio-economic background information was collected through a home interview. The median age of thelarche was 10 years and 4 months, regardless of ethnic group. Multivariant models showed that an increase of one z score unit of body mass index (BMI) decreased the median age of thelarche by 5.6 months (CI: -7.24 to -3.90), controlling for the effect of different covariables. A decrease in one z score of height retards the median age of thelarche by 5.5 months (CI: 4.02 to 6.98). Ethnicity did not influence the age of thelarche. The age of thelarche found by us is similar to that reported in international studies, it comes earlier as weight increases, is delayed as height decreases and is not related to ethnicity.

The current longitudinal study examined Mexican-origin mothers' cultural characteristics and ethnic socialization efforts as predictors of their adolescent daughters' ethnic-racial identity (ERI) exploration, resolution, and affirmation. Participants were 193 Mexican-origin adolescent mothers (M age = 16.78 years; SD = .98) and their mothers (M age = 41.24 years; SD = 7.11). Findings indicated that mothers' familism values and ERI exploration were positively associated with mother-reported ethnic socialization efforts 1 year later. Furthermore, mothers' ERI affirmation was a significant positive predictor of adolescents' ERI affirmation 2 years later, accounting for adolescents' ERI affirmation 1 year earlier. Discussion emphasizes the significance of ERI development among adolescent mothers who are negotiating the normative development of ERI and faced with their new role as parents and cultural socializers of their young children.

To explore the impact of parental ethnicity on cochlear implantation in children in Norway with regard to incidence rates of cochlear implants (CIs), comorbidies, age at onset of profound deafness (AOD), age at first implantation, uni- or bilateral CI, and speech recognition. This retrospective cohort study included all children (N = 278) aged <18 years in Norway who received their first CI during the years 2004-2010. 86 children (30.9%) in our study sample had parents of non-Nordic ethnicity, of whom 46 were born in Nordic countries with two non-Nordic parents. Compared with the background population, children with non-Nordic parents were 1.9 times more likely to have received CI than Nordic children (i.e., born in Nordic countries with Nordic parents). When looking at AOD, uni-vs. bilateral CIs, and comorbidities, no significant differences were found between Nordic children and children with a non-Nordic ethnicity. Among children with AOD <1 year (n = 153), those born in non-Nordic countries with two non-Nordic parents (n = 6) and adopted non-Nordic children (n = 6) received their first CI on average 14.9 and 21.1 months later than Nordic children (n = 104), respectively (p = 0.006 and 0.005). Among children with AOD <1 year, those born in Nordic countries with two non-Nordic parents (n = 31) received their CI at an older age than Nordic children, but this difference was not significant after adjusting for calendar year of implantation and excluding comorbidity as a potential cause of delayed implantation. The mean age at implantation for children with AOD <1 year dropped 2.3 months/year over the study period. The mean monosyllable speech recognition score was 84.7% for Nordic children and 76.3% for children born in Norway with two non-Nordic parents (p = 0.002). The incidence of CI was significantly higher in children with a non-Nordic vs. a Nordic ethnicity, reflecting a higher incidence of profound deafness. Children born in Norway have equal

Bone Age Assessment (BAA) of children is a clinical procedure frequently performed in pediatric radiology to evaluate the stage of skeletal maturation based on the left hand x-ray radiograph. The current BAA standard in the US is using the Greulich & Pyle (G&P) Hand Atlas, which was developed fifty years ago and was only based on Caucasian population from the Midwest US. To bring the BAA procedure up-to-date with today's population, a Digital Hand Atlas (DHA) consisting of 1400 hand images of normal children of different ethnicities, age, and gender. Based on the DHA and to solve inter- and intra-observer reading discrepancies, an automatic computer-aided bone age assessment system has been developed and tested in clinical environments. The algorithm utilizes features extracted from three regions of interests: phalanges, carpal, and radius. The features are aggregated into a fuzzy logic system, which outputs the calculated bone age. The previous BAA system only uses features from phalanges and carpal, thus BAA result for children over age of 15 is less accurate. In this project, the new radius features are incorporated into the overall BAA system. The bone age results, calculated from the new fuzzy logic system, are compared against radiologists' readings based on G&P atlas, and exhibits an improvement in reading accuracy for older children.

It takes two: the role of partner ethnicity and age characteristics on condom negotiations of heterosexual Chinese and Filipina American college women.

To date, limited attention is paid to how partners influence the condom negotiation process. This study examined whether partner ethnicity and age were associated with condom negotiations (i.e., verbal-direct, verbal-indirect, nonverbal-direct, nonverbal-indirect) in heterosexual Chinese and Filipina American college women. Results from 181 women across four California universities indicated significant effects of partner ethnicity and age on condom negotiation strategies. Asian women with non-Asian partners were more likely to use nonverbal-direct strategies than those with Asian partners. Asian women with older partners were less likely to use verbal strategies (verbal-direct, verbal-indirect) than those with same-age partners. This study suggests that Asian women's safer sex communication varies by partner characteristics. Obtaining information such as partner ethnicity and age can help health educators provide more culturally appropriate sexual communication skills to clients.

An index that assesses the multidimensional components of the diet across the lifecycle is useful in describing diet quality. The purpose of this study was to use the Healthy Eating Index-2005, a measure of diet quality in terms of conformance to the 2005 Dietary Guidelines for Americans, to describe the diet quality of Americans by varying sociodemographic characteristics in order to provide insight as to where diets need to improve. The Healthy Eating Index-2005 scores were estimated using 1 day of dietary intake data provided by participants in the 2003-2004 National Health and Nutrition Examination Survey. Mean daily intakes of foods and nutrients, expressed per 1,000 kilocalories, were estimated using the population ratio method and compared with standards that reflect the 2005 Dietary Guidelines for Americans. Participants included 3,286 children (2 to 17 years), 3,690 young and middle-aged adults (18 to 64 years), and 1,296 older adults (65+ years). Results are reported as percentages of maximum scores and tested for significant differences (P ≤ 0.05) by age, sex, race/ethnicity, income, and education levels. Children and older adults had better-quality diets than younger and middle-aged adults; women had better-quality diets than men; Hispanics had better-quality diets than blacks and whites; and diet quality of adults, but not children, generally improved with income level, except for sodium. The diets of Americans, regardless of socioeconomic status, are far from optimal. Problematic dietary patterns were found among all sociodemographic groups. Major improvements in the nutritional health of the American public can be made by improving eating patterns. Published by Elsevier Inc.

Low intake of nutrients is associated with poor health outcomes. We examined the contribution of dietary supplementation to meeting recommended dietary intakes of calcium, magnesium, potassium, and vitamin C in participants of the Multi-Ethnic Study of Atherosclerosis, a cohort of white, African-American, Hispanic, and Chinese-American participants ages 45 to 84 years. We also assessed the prevalence of intakes above Tolerable Upper Intake Levels (ULs). At the baseline exam in 2000-2001, 2,938 men and 3,299 women completed food frequency questionnaires and provided information about dietary supplementation. We used relative risk regression to estimate the probability of meeting Recommended Dietary Allowances (RDAs) or Adequate Intakes (AIs) in supplement users vs nonusers and Fisher's exact tests to compare the proportion of those exceeding ULs between the two groups. RDAs, AIs, and ULs were defined by the National Academy of Sciences Food and Nutrition Board's Dietary Reference Intakes (DRIs). After adjustment for age and education, the relative risk of meeting RDAs or AIs in supplement-users vs nonusers ranged from 1.9 (1.6, 2.3) in white men to 5.7 (4.1, 8.0) in African-American women for calcium, from 2.5 (1.9, 3.3) in Hispanic men to 5.2 (2.4, 11.2) in Chinese men for magnesium, and from 1.4 (1.3, 1.5) in African-American women to 2.0 (1.7, 2.2) in Chinese men for vitamin C. The relative risks for meeting RDAs for calcium differed significantly by ethnicity (P<0.001) and sex (P<0.001), and by ethnicity for magnesium (P=0.01). The relative risk for each sex/ethnicity strata was close to 1 and did not reach statistical significance at alpha=.05 for potassium. For calcium, 15% of high-dose supplement users exceeded the UL compared with only 2.1% of nonusers. For vitamin C, the percentages were 6.6% and 0%, and for magnesium, 35.3% and 0% (P<0.001 for all). Although supplement use is associated with meeting DRI guidelines for calcium, vitamin C and magnesium, many

Anthropometric dimensions of the end users should be measured in order to create a basis for manufacturing of different products. This study was designed to measure some static anthropometric dimensions in Iranian high school students, considering ethnic differences. Nineteen static anthropometric dimensions of high school students were measured and compared among different Iranian ethnicities (Fars, Turk, Kurd, Lor, Baluch, and Arab) and different genders. In this study, 9,476 subjects (4,703 boys and 4,773 girls) ages 15 to 18 years in six ethnicities were assessed. The difference among ethnicities was statistically significant for all dimensions (p values < .001 for each dimension). This study showed statistically significant differences in 19 static anthropometric dimensions among high school students regarding gender, age, and ethnicity. © 2014, Human Factors and Ergonomics Society.

Most melanoma studies use data from the National Cancer Institute Surveillance, Epidemiology, and End Results Program or individual cancer registries. Small numbers of melanoma cases have limited in-depth analyses for all racial and ethnic groups. We sought to describe racial and ethnic variations in melanoma incidence and survival. Incidence for invasive melanoma and 5-year melanoma-specific survival were calculated for whites, blacks, American Indians/Alaskan Natives, Asians/Pacific Islanders (API), and Hispanics using data from 38 population-based cancer registries. Incidence rates of melanoma were significantly higher for females than males among whites and Hispanics under 50 years of age and APIs under 40 years of age. White and black patients were older (median age: 59-63 years) compared with Hispanics, American Indians/Alaskan Natives, and API (median age: 52-56 years). The most common histologic type was acral lentiginous melanoma among blacks and superficial spreading melanoma among all other racial and ethnic groups. Hispanics had the highest incidence rate of acral lentiginous melanoma, significantly higher than whites and API. Nonwhites were more likely to have advanced and thicker melanomas at diagnosis and lower melanoma-specific survival compared with whites. Over 50% of melanoma cases did not have specified histology. The numbers of nonwhite patients were still relatively small despite broad population coverage (67% of United States). Racial and ethnic differences in age at melanoma diagnosis, anatomic sites, and histologic types suggest variations in etiologic pathways. The high percentages of advanced and thicker melanomas among nonwhites highlight the need to improve melanoma awareness for all race and ethnicity in the United States.

We geocoded addresses of 9740 children younger than 15 years of age from 2000-2010 California shigellosis surveillance data and calculated incidence rate (IR) per 100,000 population by age group and race/ethnicity. We linked geocoded cases to 2006-2010 American Community Survey CT-level poverty data and used IR ratios to compare children in the most impoverished CTs with those in the least impoverished CTs. The contribution of socioeconomic inequalities to age-standardized racial and ethnic disparities was explored using Poisson regression. Per 100,000 population, shigellosis IR was highest among California children less than 5 years old (16.4) and of Hispanic ethnicity (15.2). The age-standardized IR was 22.3 per 100,000 person-years in CTs with more than 40% of the population below the poverty line and 4.1 per 100,000 person-years in CTs with less than 5% of the population below the poverty line, an IR ratio of 5.8 (95% confidence interval: 5.2, 6.5). Shigellosis rates among California children were highest among Hispanics and increased with CT poverty.

Limited population-based data exist on differences in the incidence of major pathological stroke types and ischaemic stroke subtypes across ethnic groups. We aimed to provide such data within the large multi-ethnic population of Auckland, New Zealand. All first-ever cases of stroke (n=1423) in a population-based register in 940 000 residents (aged 15 years) in Auckland, New Zealand, for a 12-month period in 2002-2003, were classified into ischaemic stroke, primary intracerebral haemorrhage (PICH), subarachnoid haemorrhage, and undetermined stroke, according to standard definitions and results of neuroimaging/necropsy (in over 90% of cases). Ischaemic stroke was further classified into five subtypes. Ethnicity was self-identified and grouped as New Zealand (NZ)/European, Maori/Pacific, and Asian/other. Incidence rates were standardised to the WHO world population by the direct method, and differences in rates between ethnic groups expressed as rate ratios (RRs), with NZ/European as the reference group. In NZ/European people, ischaemic stroke comprised 73%, PICH 11%, and subarachnoid haemorrhage 6%, but PICH was higher in Maori/Pacific people (17%) and in Asian/other people (22%). Compared with NZ/European people, age-adjusted RRs for PICH were 2.7 (95% CI 1.8-4.0) and 2.3 (95% CI 1.4-3.7) among Maori/Pacific and Asian/other people, respectively. The corresponding RR for ischaemic stroke was greater for Maori/Pacific people (1.7 [95% CI 1.4-2.0]), particularly embolic stroke, and for Asian/other people (1.3 [95% CI 1.0-1.7]). The onset of stroke in Maori/Pacific and Asian/other people began at significantly younger ages (62 years and 64 years, respectively) than in NZ/Europeans (75 years; p<0.0001). There were ethnic differences in the risk factor profiles (such as age, sex, hypertension, cardiac disease, diabetes, hypercholesterolaemia, smoking status, overweight) for the stroke types and subtypes. Compared to NZ/Europeans, Maori/Pacific and Asian/other people are

This study examines how benefits, costs, opportunities, and preferences affect ethnic differences in parent-child coresidence in Malaysia. The conceptual model is described in greater detail in a companion paper. Data were obtained from the senior sample of the Second Malaysian Family Life Survey of 1988-89. The nationally representative sample includes 1229 persons aged over 50 years living in private households. Retirement age in Malaysia is 45 years for women and 55 years for men. Ethnicity includes Malay, Chinese, and Indians. Adult children are aged 20 years and older. The analysis pertains to 802 married and 427 unmarried seniors. Chinese tended to live in the most expensive areas and urban areas. Malays tended to live in the least expensive areas and rural areas. Health perception ranged from good to fair to poor. About 20% of married seniors had wives aged under 50 years. Income refers to average monthly unearned income, excluding transfers from other households or public sources. The relative roles of ethnic differences in each explanatory variable are estimated. Findings indicate that the higher incidence of remarriage and lower housing costs for married Malays explain their lower coresidence rates. The poorer health of Indians and better health of Malays also explain coresidence differences for the married. The higher incidence of daughter-only families among Malays explains coresidence differences. The explanatory variables of remarriage, housing costs, health, and daughter-only families explain little for the unmarried. Among the unmarried and the married, older age was associated with greater coresidence for the Chinese only. Chinese and Malay coresidence declined with increased educational levels. Coresidence rates were lower for Malays and higher for Indians.

Pro-gastrin-releasing peptide (ProGRP) is a kind of tumor marker applied more and more commonly in recent years. This study was aimed at determining the age and gender-specific reference intervals (RIs) for ProGRP in healthy Han ethnic adults from Guangxi, China. A total of 2,045 apparently healthy males and 1,740 apparently healthy females aged from 21 to 90 years were included in this study. The serum ProGRP values were determined by electrochemiluminescence immunoassay (ECLIA). The one-sided upper 95th percentile of ProGRP concentrations were used to define the RIs. The reference limits in different age groups (21 - 40, 41 - 50, 51 - 60, 61 - 70, and > 70 years) were 37.3, 39.7, 45.7, 47.3, and 61.3 pg/mL for males, and 36.3, 38.1, 42.7, 53.5, and 60.1 pg/mL for females, respectively. There was no significant difference in the levels of ProGRP between males and females. The serum ProGRP levels were positively correlated with age. We established the age and gender-specific RIs for ProGRP in the adults from Guangxi, China. It will be valuable for future clinical and laboratory studies.

To investigate the effect of racism, own-group ethnic density, diversity and deprivation on adolescent trajectories in psychological well-being. Multilevel models were used in longitudinal analysis of psychological well-being (total difficulties score (TDS) from Goodman's Strengths and Difficulties Questionnaire, higher scores correspond to greater difficulties) for 4782 adolescents aged 11-16 years in 51 London (U.K.) schools. Individual level variables included ethnicity, racism, gender, age, migrant generation, socio-economic circumstances, family type and indicators of family interactions (shared activities, perceived parenting). Contextual variables were per cent eligible for free school-meals, neighbourhood deprivation, per cent own-group ethnic density, and ethnic diversity. Ethnic minorities were more likely to report racism than whites. Ethnic minority boys (except Indian boys) and Indian girls reported better psychological well-being throughout adolescence compared to their white peers. Notably, lowest mean TDS scores were observed for Nigerian/Ghanaian boys, among whom the reporting of racism increased with age. Adjusted for individual characteristics, psychological well-being improved with age across all ethnic groups. Racism was associated with poorer psychological well-being trajectories for all ethnic groups (p<0.001), reducing with age. For example, mean difference in TDS (95% confidence interval) between boys who experienced racism and those who did not at age 12 years=1.88 (+1.75 to +2.01); at 16 years = +1.19 (+1.07 to +1.31). Less racism was generally reported in schools and neighbourhoods with high than low own-group density. Own ethnic density and diversity were not consistently associated with TDS for any ethnic group. Living in more deprived neighbourhoods was associated with poorer psychological well-being for whites and black Caribbeans (p<0.05). Racism, but not ethnic density and deprivation in schools or neighbourhoods, was an important

Kawasaki disease (KD) primarily affects children <5 years of age (75%–80%) and is currently the leading cause of acquired heart disease in developed nations. Even when residing in the West, East Asian children are 10 to 20 times more likely to develop KD. We hypothesized cultural variations influencing pediatric mercury (Hg) exposure from seafood consumption may mediate ethnic KD risk among children in the United States. Hospitalization rates of KD in US children aged 0–4 years (n = 10,880) and blood Hg levels in US children aged 1–5 years (n = 713) were determined using separate US federal datasets. Our cohort primarily presented with blood Hg levels <0.1 micrograms (µg) per kg bodyweight (96.5%) that are considered normal and subtoxic. Increased ethnic KD risk was significantly associated with both increasing levels and detection rates of blood Hg or cadmium (Cd) in a linear dose-responsive manner between ethnic African, Asian, Caucasian, and Hispanic children in the US (p ≤ 0.05). Increasing low-dose exposure to Hg or Cd may induce KD or contribute to its later development in susceptible children. However, our preliminary results require further replication in other ethnic populations, in addition to more in-depth examination of metal exposure and toxicokinetics. PMID:26742052

Influenza is responsible for a large number of deaths which can only be estimated using modelling methods. Such methods have rarely been applied to describe the major socio-demographic characteristics of this disease burden. We used quasi Poisson regression models with weekly counts of deaths and isolates of influenza A, B and respiratory syncytial virus for the period 1994 to 2008. The estimated average mortality rate was 13.5 per 100,000 people which was 1.8% of all deaths in New Zealand. Influenza mortality differed markedly by age, sex, ethnicity and socioeconomic position. Relatively vulnerable groups were males aged 65-79 years (Rate ratio (RR) = 1.9, 95% CI: 1.9, 1.9 compared with females), Māori (RR = 3.6, 95% CI: 3.6, 3.7 compared with European/Others aged 65-79 years), Pacific (RR = 2.4, 95% CI: 2.4, 2.4 compared with European/Others aged 65-79 years) and those living in the most deprived areas (RR = 1.8, 95% CI: 1.3, 2.4) for New Zealand Deprivation (NZDep) 9&10 (the most deprived) compared with NZDep 1&2 (the least deprived). These results support targeting influenza vaccination and other interventions to the most vulnerable groups, in particular Māori and Pacific people and men aged 65-79 years and those living in the most deprived areas.

Biological modelling of routinely collected newborn screening data has emerged as a novel method for deriving postnatal gestational age estimates. Validation of published models has previously been limited to cohorts largely consisting of infants of white Caucasian ethnicity. In this study, we sought to determine the validity of a published gestational age estimation algorithm among recent immigrants to Canada, where maternal landed immigrant status was used as a surrogate measure of infant ethnicity. We conducted a retrospective validation study in infants born in Ontario between April 2009 and September 2011. Provincial data from Ontario, Canada were obtained from the Institute for Clinical Evaluative Sciences. The dataset included 230 034 infants born to non-landed immigrants and 70 098 infants born to immigrant mothers. The five most common countries of maternal origin were India (n=10 038), China (n=7468), Pakistan (n=5824), The Philippines (n=5441) and Vietnam (n=1408). Maternal country of origin was obtained from Citizenship and Immigration Canada's Landed Immigrant Database. Performance of a postnatal gestational age algorithm was evaluated across non-immigrant and immigrant populations. Root mean squared error (RMSE) of 1.05 weeks was observed for infants born to non-immigrant mothers, whereas RMSE ranged from 0.98 to 1.15 weeks among infants born to immigrant mothers. Area under the receiver operating characteristic curve for distinguishing term versus preterm infants (≥37 vs <37 weeks gestational age or >34 vs ≤34 weeks gestational age) was 0.958 and 0.986, respectively, in the non-immigrant subgroup and ranged from 0.927 to 0.964 and 0.966 to 0.99 in the immigrant subgroups. Algorithms for postnatal determination of gestational age may be further refined by development and validation of region or ethnicity-specific models. However, our results provide reassurance that an algorithm developed from Ontario-born infant cohorts performs well

Childhood lead poisoning is a serious public health problem with long-term adverse effects. Healthy People 2020's environmental health objective aims to reduce childhood blood lead levels; however, efforts may be hindered by potential racial/ethnic differences. Recent recommendations have lowered the blood lead reference level. This review examined racial/ethnic differences in blood lead levels among children under 6 years of age. We completed a search of PubMed, CINAHL, and PsycINFO databases for published works from 2002 to 2012. We identified studies that reported blood lead levels and the race/ethnicity of at least two groups. Ten studies met inclusion criteria for the review. Blood lead levels were most frequently reported for black, white, and Hispanic children. Six studies examined levels between blacks, whites, and Hispanics and two between blacks and whites. Studies reporting mean lead levels among black, whites, and Hispanics found that blacks had the highest mean blood lead level. Additionally, studies reporting blood lead ranges found that black children were more likely to have elevated levels. Studies suggest that black children have higher blood lead levels compared to other racial/ethnic groups. Future studies are warranted to obtain ample sample sizes for several racial/ethnic groups to further examine differences in lead levels.

Studies on adult racial/ethnic minority populations show that the increased concentration of racial/ethnic minorities in a neighbourhood-a so-called ethnic density effect-is associated with improved health of racial/ethnic minority residents when adjusting for area deprivation. However, this literature has focused mainly on adult populations, individual racial/ethnic groups, and single countries, with no studies focusing on children of different racial/ethnic groups or comparing across nations. This study aims to compare neighbourhood ethnic density effects on young children's cognitive and behavioural outcomes in the US and in England. We used data from two nationally representative birth cohort studies, the US Early Childhood Longitudinal Study-Birth Cohort and the UK Millennium Cohort Study, to estimate the association between own ethnic density and behavioural and cognitive development at 5 years of age. Findings show substantial heterogeneity in ethnic density effects on child outcomes within and between the two countries, suggesting that ethnic density effects may reflect the wider social and economic context. We argue that researchers should take area deprivation into account when estimating ethnic density effects and when developing policy initiatives targeted at strengthening and improving the health and development of racial and ethnic minority children.

Use of neuropsychological tests to identify HIV-associated neurocognitive dysfunction must involve normative standards that are well-suited to the population of interest. Norms should be based on a population of HIV-uninfected individuals as closely matched to the HIV-infected group as possible, and must include examination of the potential effects of demographic factors on test performance. This is the first study to determine the normal range of scores on measures of psychomotor speed and executive function among a large group of ethnically and educationally diverse HIV-uninfected, high risk women, as well as their HIV-infected counterparts. Participants (n = 1653) were administered the Trailmaking Test Parts A and B (Trails A and Trails B), the Symbol Digit Modalities Test (SDMT), and the Wide Range Achievement Test-3 (WRAT-3). Among HIV-uninfected women, race/ethnicity accounted for almost 5% of the variance in cognitive test performance. The proportion of variance in cognitive test performance accounted for by age (13.8%), years of school (4.1%) and WRAT-3 score (11.5%) were each significant, but did not completely account for the effect of race (3%). HIV-infected women obtained lower scores than HIV-uninfected women on time to complete Trails A and B, SDMT total correct, and SDMT incidental recall score, but after adjustment for age, years of education, racial/ethnic classification, and reading level, only the difference on SDMT total correct remained significant. Results highlight the need to adjust for demographic variables when diagnosing cognitive impairment in HIV-infected women. Advantages of demographically adjusted regression equations developed using data from HIV-uninfected women are discussed. PMID:21950512

The prevalence of obesity is increasing rapidly and abdominal obesity especially is known to be a risk factor for metabolic syndrome and other non-communicable diseases. Waist circumference percentile curves are useful tools which can help to identify abdominal obesity among the childhood and adolescent populations. To develop age- and sex-specific waist circumference (WC) percentile curves for multi-ethnic Malaysian children and adolescents aged 6.0-16.9 years. Subjects and methods. A total of 16,203 participants comprising 8,093 boys and 8,110 girls recruited from all regions of Malaysia were involved in this study. Height, weight, WC were measured and BMI calculated. Smoothed WC percentile curves and values for the 3rd, 5th, 10th, 25th, 50th, 75th, 90th, 95th and 97th percentiles were constructed using the LMS Method. WC was found to increase with age in both sexes, but boys had higher WC values at every age and percentile. Z-scores generated using the UK reference data shows that Chinese children had the highest WC compared to Malays, Indians and other ethnicities. Comparisons with other studies indicate that at the 50th percentile, Malaysian curves did not differ from the UK, Hong Kong and Turkish curves, but at the 90th percentile, Malaysian curves were higher compared with other countries, starting at 10 years of age. The 90th percentile was adopted as the cut-off point to indicate abdominal obesity in Malaysian children and adolescents. These curves represent the first WC percentiles reported for Malaysian children, and they can serve as a reference for future studies.

Two distinct ethnic groups live in Southern Israel: urban Jews and rural Bedouin Arabs. These groups differ in their socioeconomic status, culture and living environment, and are treated in a single regional tertiary care hospital. We hypothesized that these two ethnic groups have different patterns of sepsis-related intensive care admissions. The study included all adult patients admitted to the Soroka University Medical Center Intensive Care Units between January 2002 and December 2008, with a diagnosis of sepsis. Demographic data, medical history, and hospitalization and outcomes data were obtained. Primary outcome was all-cause mortality. Jewish patients admitted to the ICU (1343, 87%) were on average 17 years older than Bedouin Arabs (199, 13%). For the population <65 years, Bedouin Arabs had slightly higher age-adjusted prevalence of ICU sepsis admissions than Jewish patients (39.5 vs. 43.0, p=0.25), while for the population >65 years there was a reverse trend (21.8 vs. 19.8 p=0.49). There were no differences in the type of organ failure, sepsis severity or length of hospitalization between the two groups. Twenty eight days/in-hospital mortality was 33.9% in Bedouin Arabs vs. 45.5% in Jews, p=0.004. Following adjustment for comorbidities, age and severity of the disease, survival was unrelated to ethnicity, both at 28 days (odds ratio for Bedouin Arabs 0.86, 95% CI 0.66-1.24) and following hospital discharge (hazard ratio 0.86, 95% 0.67-1.09). Sepsis-related ICU admissions are more prevalent among Bedouin Arabs at younger age compared with the Jewish population. Adjusted for confounders, ethnicity does not influence prognosis.

Objectives. We examined the prevalence and associations between behavioral and identity dimensions of sexual orientation among adolescents in the United States, with consideration of differences associated with race/ethnicity, sex, and age. Methods. We used pooled data from 2005 and 2007 Youth Risk Behavior Surveys to estimate prevalence of sexual orientation variables within demographic sub-groups. We used multilevel logistic regression models to test differences in the association between sexual orientation identity and sexual behavior across groups. Results. There was substantial incongruence between behavioral and identity dimensions of sexual orientation, which varied across sex and race/ethnicity. Whereas girls were more likely to identify as bisexual, boys showed a stronger association between same-sex behavior and a bisexual identity. The pattern of association of age with sexual orientation differed between boys and girls. Conclusions. Our results highlight demographic differences between 2 sexual orientation dimensions, and their congruence, among 13- to 18-year-old adolescents. Future research is needed to better understand the implications of such differences, particularly in the realm of health and health disparities. PMID:24328662

Quantitative evaluation of variance in secondary dentition eruption among ethnic groups in Hawai'i.

PubMed

Greer, Mark H K; Loo, Kevin J

2003-03-01

Though little scientific evidence existed to support the belief among dentists who treat Pacific Islander populations that many children of the region erupt secondary teeth earlier and at an eruption rate which exceeds Caucasian children. Based upon a data set created in Hawai'i during the 1998-1999 school year, of 26,097 public school children, the opportunity presented itself to examine for variance in eruption timing and sequence. Hawai'i is an ethnic diverse community, with a majority population comprised of Asians and Pacific Islanders. Children, 5 through 9 years of age, were examined for gender and ethnic variance. In the aggregate, at all ages, girls erupted teeth earlier than boys, however, while generally true among individual tooth types, that variance was not always statistically significant. By ethnic group, African Americans exhibited earlier eruption by contrast with Caucasians, however, Caucasian children caught up by nine years of age. Native Hawaiian, Samoan and Tongan children exhibited earlier and high rates of secondary dentition eruption than Caucasian or African American children. Children of various Asian cohorts did not exhibit significant variance by contrast with Caucasians. Based upon these findings, the authors recommend that dietary fluoride supplementation of Native Hawaiian, Samoan and Tongan children begin at birth rather than 6 months of age and that these children be targeted for pit & fissure sealants as early as five years of age.

The present study examined whether the cross-sectional association between body dissatisfaction and low self-esteem varies across gender, age, body weight status, race/ethnicity, and socioeconomic status (SES). We also examined the association longitudinally. A school-based survey of eating, weight, and related attitudes was conducted with a diverse sample of adolescents aged 11-18 years (N = 4,746). Height and weight were measured in the schools at Time 1. Participants were resurveyed through mails 5 years later (Time, 2; N = 2,516). The relationship between body dissatisfaction and self-esteem was strong and significant in both boys and girls (all p values < .0001), and did not differ significantly between genders (p = .16), or between the middle school and high school cohorts in either boys (p = .79) or girls (p = .80). Among girls, the relationship between body dissatisfaction and self-esteem was strong, but did vary across weight status, race/ethnicity, and SES (all p values = .0001-.03). The relationship was nonsignificant in underweight girls (p = .36), and weaker but still significant among black, Asian, and low SES group girls (all p values < .0001) in comparison to white and high SES group girls. Among boys, the association did not differ significantly across demographic groups (all p values = .18-.79). In longitudinal analyses, the strength of the association did not change significantly as adolescents grew older. Findings indicate that body dissatisfaction and self-esteem are strongly related among nearly all groups of adolescents. This suggests the importance of addressing body image concerns with adolescents of all backgrounds and ages.

Purpose The present study examined whether the cross-sectional association between body dissatisfaction and low self-esteem varies across gender, age, body weight status, race/ethnicity, and SES. We also examined the association longitudinally. Methods A school-based survey of eating, weight, and related attitudes was conducted with a diverse sample of adolescents aged 11–18 years (N = 4,746). Height and weight were measured in the schools at Time 1. Participants was resurveyed by mail five years later (Time 2, N = 2,516). Results The body dissatisfaction/self-esteem association was strong and significant in both boys and girls (p’s<.0001), and did not differ significantly between genders (p =.16), nor between the middle school and high school cohorts in either boys (p=.79) or girls (p=.80). Among girls, the body dissatisfaction/self-esteem relationship was strong, but did vary across weight status, race/ethnicity, and SES (p’s .0001–.03). The relationship was non-significant in underweight girls (p=.36), and weaker but still significant among black, Asian, and low SES girls (all p’s <.0001) in comparison to white and high SES group girls. Among boys, the association did not differ significantly across demographic groups (p’s .18–.79). In longitudinal analyses, the strength of the association did not change significantly as adolescents grew older. Conclusions Findings indicate that body dissatisfaction and self-esteem are strongly related among nearly all groups of adolescents. This suggests the importance of addressing body image concerns with adolescents of all backgrounds and ages. PMID:20708569

The influence of ethnicity on pain complicating ultrasound-guided percutaneous liver biopsy (US-guided PLB) and its clinical impact has not been reported to date. Consecutive adults from a multiethnic background, undergoing an US-guided PLB, were independently assessed for pain up to 6 h after the procedure. Clinical and demographic parameters were analysed to determine independent predictors of significant pain after PLB. Willingness to undergo a repeat procedure was assessed 1 week after PLB. Data from 203 patients (median age 50 years; 43.9% female; ethnicity: Malay 41.5%, Chinese 40%, Indian 18%; median BMI 27.7 kg/m; median waist circumference 92.0 cm) were analysed. Pain after US-guided PLB was experienced in 133 (61.1%) patients, with severity grades as follows: none, n=81 (39.9%); mild, n=56 (27.6%); moderate, n=51 (25.1%); and severe, n=15 (7.4%). Analgesia requirements correlated well with severity of pain. Independent predictors of significant pain after PLB (moderate and severe categories) in patients included age less than 50 years [odds ratio (OR) 3.0], female sex (OR 3.7), Indian ethnicity (OR 2.9) and Malay ethnicity (OR 2.7), but not number of needle passes, BMI and educational levels. Patients who experienced moderate/severe pain were less willing to undergo a repeat PLB compared with those who experienced mild/no pain (60.9 vs. 82.8%, P=0.001). Ethnicity has an important role in the development of pain after US-guided PLB. This has a significant impact on willingness to repeat the procedure.

Background Osteoporosis is a significant health problem in the developing countries and its prevalence data are important for the estimation of health care burden and policy making. This study aimed to determine the age-related changes in bone health and the prevalence of osteoporosis in males and females aged 50 years or above living in Kuala Lumpur, Malaysia. Methods A cross-sectional study was conducted between December 2014 and December 2015. Subjects answered a demographic questionnaire and underwent body anthropometric and bone health measurement. Assessment of bone health was performed using a quantitative ultrasound device that generated speed of sound, broadband ultrasound attenuation, stiffness index, and T-score based on stiffness index value as bone health indices. Results The prevalence of osteoporosis was 10.6% in males and 8.0% in females. Significant age-related decline of bone health indices (speed of sound, broadband ultrasound attenuation, stiffness index, and T-score) and a concurrent increase in the prevalence of osteoporosis and osteopenia were observed in females (P<0.05) but not in males (P>0.05). Ethnic differences in bone health indices and prevalence of osteoporosis/osteopenia were not observed (P>0.05). Conclusion A significant proportion of males and females age 50 years or above have suboptimal bone health. Preventive measures such as early screening should be implemented to retard the progression of osteoporosis. PMID:27358558

The purpose of this study is to determine the past-year prevalence estimates of any nicotine/tobacco use, cigarette smoking, and DSM-5 tobacco use disorder based on sexual identity among U.S. adults, and to examine potential variations in these estimates by age, race/ethnicity, and sexual identity-attraction concordance/discordance. The 2012-2013 National Epidemiologic Survey on Alcohol and Related Conditions collected data via in-person interviews with a cross-sectional nationally representative sample of non-institutionalized adults (response rate=60.1%) and analyses for the present study were conducted in 2017. Any past-year nicotine/tobacco use, cigarette smoking, and DSM-5 tobacco use disorder were most prevalent among sexual minority-identified adults compared with heterosexual-identified adults, with notable variations based on sex, age, race/ethnicity, and sexual identity-attraction discordance. Elevated rates of any nicotine/tobacco use, cigarette smoking, and DSM-5 tobacco use disorder among sexual minorities were most prevalent among younger lesbian women and gay men, and all age groups of bisexual men and women. The odds of any nicotine/tobacco use, cigarette smoking, and DSM-5 tobacco use disorder were significantly greater among sexual identity-attraction discordant women and significantly lower among sexual identity-attraction discordant men. These findings provide valuable new information about sexual minority subgroups, such as self-identified bisexual older adults and sexual identity-attraction discordant women, that appear to be at higher risk for adverse smoking-related health consequences as a result of their elevated rates of cigarette smoking. Additional attention is warranted to examine these high-risk subpopulations prospectively and, if the results are replicated with larger samples, this information can be used to target smoking-cessation and lung cancer screening efforts.

Data on dementia prognosis among ethnic minority groups are limited in Europe. We assessed differences in short-term (1-year) and long-term (3-year) mortality and readmission risk after a first hospitalization or first ever referral to a day clinic for dementia between ethnic minority groups and the ethnic Dutch population in the NetherlandsMethods: Nationwide prospective cohorts of first hospitalized dementia patients (N = 55,827) from January 1, 2000 to December 31, 2010 were constructed. Differences in short-term and long-term mortality and readmission risk following hospitalization or referral to the day clinic between ethnic minority groups (Surinamese, Turkish, Antilleans, Indonesians) and the ethnic Dutch population were investigated using Cox proportional hazard regression models with adjustment for age, sex, and comorbidities. Age-sex-adjusted short-term and long-term risks of death following a first hospitalization with dementia were comparable between the ethnic minority groups and the ethnic Dutch. Age- and sex-adjusted risk of admission was higher only in Turkish compared with ethnic Dutch (HR 1.57, 95% CI,1.08-2.29). The difference between Turkish and the Dutch attenuated and was no longer statistically significant after further adjustment for comorbidities. There were no ethnic differences in short-term and long-term risk of death, and risk of readmission among day clinic patients. Compared with Dutch patients with a comparable comorbidity rate, ethnic minority patients with dementia did not have a worse prognosis. Given the poor prognosis of dementia, timely and targeted advance care planning is essential, particularly in ethnic minority groups who are mired by cultural barriers and where uptake of advance care planning is known to be low.

Background Each ethnic group has its own cultural values and practices that widen inequalities in child health and survival among ethnic groups. This study seeks to examine the mediatory effects of ethnicity and socioeconomic position on under-5 mortality in Nigeria. Methods Using multilevel logistic regression analysis of a nationally representative sample drawn from 7620 females age 15 to 49 years in the 2003 Nigeria Demographic and Health Survey, the risk of death in children younger than 5 years (under-5 deaths) was estimated using odds ratios with 95% confidence intervals for 6029 children nested within 2735 mothers who were in turn nested within 365 communities. Results The prevalence of under-5 death was highest among children of Hausa/Fulani/Kanuri mothers and lowest among children of Yoruba mothers. The risk of under-5 death was significantly lower among children of mothers from the Igbo and other ethnic groups, as compared with children of Hausa/Fulani/Kanuri mothers, after adjustment for individual- and community-level factors. Much of the disparity in under-5 mortality with respect to maternal ethnicity was explained by differences in physician-provided community prenatal care. Conclusions Ethnic differences in the risk of under-5 death were attributed to differences among ethnic groups in socioeconomic characteristics (maternal education and to differences in the maternal childbearing age and short birth-spacing practices. These findings emphasize the need for community-based initiatives aimed at increasing maternal education and maternal health care services within communities. PMID:20877142

Background Minority groups generally experience more disparities than whites in behavioral healthcare use. The population of racial/ethnic groups is growing faster than whites. Given increased concerns of cannabis use (CU) and its associations with health conditions, we examined national trends in cannabis use disorder (CUD) among adults aged ≥18 by race/ethnicity. Methods Data were from the 2005–2013 National Surveys on Drug Use and Health (N=340,456). We compared CU patterns and the conditional prevalence of CUD among cannabis users by race/ethnicity to understand racial/ethnic variations in CUD. Results Approximately 1.5 % of adults met criteria for a CUD in the past year. Regardless of survey year, cannabis dependence was more common than cannabis abuse, representing 66% of adults with a CUD. Across racial/ethnic groups, the prevalence of cannabis abuse and dependence remained stable during 2005–2013. In the total adult sample, the odds of weekly CU, monthly CU, and cannabis dependence were greater among blacks, native-Americans, and mixed-race adults than whites. Among cannabis users, the odds of cannabis abuse and dependence were greater among blacks, native-Americans, and Hispanics than whites. Logistic regression controlling for age, sex, education, and survey year indicated an increased trend in monthly CU and weekly CU in the total sample and among past-year cannabis users. Younger age, male sex, and low education were associated with increased odds of cannabis dependence. Conclusions The large sample provides robust information that indicates a need for research to monitor CUD and identify culturally appropriate interventions especially for targeting minority populations.

The association of general medical illness and mental health service use among older adults from racial-ethnic minority groups is an important area of study given the disparities in mental health and general medical services and the low use of mental health services in this population. The purpose of this report is to describe the impact of comorbid general medical illness on mental health service use and expenditures among older adults and to evaluate disparities in mental health service use and expenditures in a racially-ethnically diverse sample of older adults with and without comorbid general medical illness. Data were obtained from the Medical Expenditure Panel Survey (years 2004-2011). The sample included 1,563 whites, 519 African Americans, and 642 Latinos (N=2,724) age ≥65 with probable mental illness. Two-part generalized linear models were used to estimate and compare mental health service use among adults with and without a comorbid general medical illness. Mental health service use was more likely for older adults with comorbid general medical illness than for those without it. Once mental health services were accessed, no differences in mental health expenditures were found. Comorbid general medical illness increased the likelihood of mental health service use by older whites and Latinos. However, the presence of comorbidity did not affect racial-ethnic disparities in mental health service use. This study highlighted the important role of comorbid general medical illness as a potential contributor to using mental health services and suggests intervention strategies to enhance engagement in mental health services by older adults from racial-ethnic minority groups.

A few studies have examined the costs of breast cancer treatment in a Medicaid population at the state level. However, no study has estimated medical costs for breast cancer treatment at the national level for women aged 19-44 years enrolled in Medicaid. A sample of 5,542 younger women aged 19-44 years enrolled in fee-for-service Medicaid with diagnosis codes for breast cancer in 2007 were compared with 4.3 million women aged 19-44 years enrolled in fee-for-service Medicaid without breast cancer. Nonlinear regression methods estimated prevalent treatment costs for younger women with breast cancer compared with those without breast cancer. Individual medical costs were estimated by race/ethnicity and by type of services. Analyses were conducted in 2013 and all medical treatment costs were adjusted to 2012 U.S. dollars. The estimated monthly direct medical costs for breast cancer treatment among younger women enrolled in Medicaid was $5,711 (95% CI=$5,039, $6,383) per woman. The estimated monthly cost for outpatient services was $4,058 (95% CI=$3,575, $4,541), for inpatient services was $1,003 (95% CI=$708, $1,298), and for prescription drugs was $539 (95% CI=$431, $647). By race/ethnicity, non-Hispanic white women had the highest monthly total medical costs, followed by Hispanic women and non-Hispanic women of other race. Cost estimates demonstrate the substantial medical costs associated with breast cancer treatment for younger Medicaid beneficiaries. As the Medicaid program continues to evolve, the treatment cost estimates could serve as important inputs in decision making regarding planning for treatment of invasive breast cancer in this population.

The nature of differences in the timing of tooth formation between ethnic groups is important when estimating age. To calculate age of transition of the mandibular third (M3) molar tooth stages from archived dental radiographs from sub-Saharan Africa, Malaysia, Japan and two groups from London UK (Whites and Bangladeshi). The number of radiographs was 4555 (2028 males, 2527 females) with an age range 10-25 years. The left M3 was staged into Moorrees stages. A probit model was fitted to calculate mean ages for transitions between stages for males and females and each ethnic group separately. The estimated age distributions given each M3 stage was calculated. To assess differences in timing of M3 between ethnic groups, three models were proposed: a separate model for each ethnic group, a joint model and a third model combining some aspects across groups. The best model fit was tested using Bayesian and Akaikes information criteria (BIC and AIC) and log likelihood ratio test. Differences in mean ages of M3 root stages were found between ethnic groups, however all groups showed large standard deviation values. The AIC and log likelihood ratio test indicated that a separate model for each ethnic group was best. Small differences were also noted between timing of M3 between males and females, with the exception of the Malaysian group. These findings suggests that features of a reference data set (wide age range and uniform age distribution) and a Bayesian statistical approach are more important than population specific convenience samples to estimate age of an individual using M3. Some group differences were evident in M3 timing, however, this has some impact on the confidence interval of estimated age in females and little impact in males because of the large variation in age.

Data monitoring trends in stroke risk among different ethnic groups are lacking. Thus, we investigated trends in stroke incidence and modifiable stroke risk factors over a 10-year time period between different ethnic groups. Changes in stroke incidence were investigated with the South London Stroke Register (SLSR). The SLSR is a population-based stroke register, covering a multiethnic population of 271 817 inhabitants in South London with 63% white, 28% black, and 9% of other ethnic group (2001 Census). Between 1995 and 2004, 2874 patients with first-ever stroke of all age groups were included. Total stroke incidence decreased over the 10-year study period in men (incidence rate ratio 1995 to 1996 versus 2003 to 2004 [IRR] 0.82, 95% CI 0.69 to 0.97) and in women (IRR 0.76, 95% CI 0.64 to 0.90). A similar decline in total stroke incidence could be observed in whites for men and women (IRR 0.76, 95% CI 0.62 to 0.93 versus IRR 0.73, 95% CI 0.59 to 0.89, respectively); in blacks, total stroke incidence was reducing only in women (IRR 0.48, 95% CI 0.31 to 0.75). In whites, the prevalence of prior-to-stroke hypertension (P=0.0017), atrial fibrillation (P=0.0113), and smoking (P=0.0177) decreased; no statistically significant changes in prior-to-stroke risk factors were observed in blacks. Total stroke incidence was higher in blacks compared to whites (IRR 1.27, 95% CI 1.10 to 1.46 in men; IRR 1.29, 95% CI 1.11 to 1.50 in women), but the black-white gap reduced during the 10-year time period (IRR 1.43, 95% CI 1.13 to 1.82 in 1995 to 1996 to 1.18, 95% CI 0.93 to 1.49 in 2003 to 2004). Stroke incidence decreased over a 10-year time period. The greatest decline in incidence was observed in black women, but ethnic group disparities still exist, indicating a higher stroke risk in black people compared to white people. Advances in risk factor reduction observed in the white population were failed transferring to the black population.

Objectives Since sex hormone markers are metabolically linked, examining sex steroid hormones singly may account for inconsistent findings by age, race/ethnicity and body mass index (BMI) across studies. First, these markers were statistically combined into profiles to account for the metabolic relationship between markers. Then, the relationships between sex steroid hormone profiles and age, race/ethnicity and BMI were explored in multinomial logistic regression models. Design Cross-sectional survey. Setting The US Third National Health and Nutrition Examination Survey (NHANES III). Participants 1538 Men, >17 years. Primary outcome measure Sex hormone profiles. Results Cluster analysis was used to identify four statistically determined profiles with Blom-transformed T, E, sex hormone binding globulin (SHBG), and 3-α diol G. We used these four profiles with multinomial logistic regression models to examine differences by race/ethnicity, age and BMI. Mexican American men >50 years were associated with the profile that had lowest T, E and 3-α diol G levels compared to other profiles (p<0.05). Non-Hispanic Black, overweight (25–29.9 kg/m2) and obese (>30 kg/m2) men were most likely to be associated with the cluster with the lowest SHBG (p<0.05). Conclusion The associations of sex steroid hormone profiles by race/ethnicity are novel, while the findings by age and BMI groups are largely consistent with observations from single hormone studies. Future studies should validate these hormone profile groups and investigate these profiles in relation to chronic diseases and certain cancers. PMID:23043125

Hypertension is an important public health issue in China, but there are few studies examining hypertension in ethnic groups in Yunnan, China. This study, Yunnan Minority Eye Study (YMES), was initially designed to determine the prevalence and impact of eye diseases, including hypertension and diabetes mellitus. As a part of YMES, the prevalence, awareness, treatment, and control of hypertension and the associated risk factors among the Yi ethnic population in rural China are reported. A population-based survey was conducted in 2012 with adult participants over 50 from rural communities in Shilin Yi Autonomous County, Yunnan Province, located in southwest China. A random cluster sampling method was used to select a representative sample. The participants' blood pressure, height, weight, and waist circumference were measured. Hypertension was defined as mean systolic blood pressure ≥140 mmHg and/or diastolic blood pressure ≥90 mmHg, and/or current use of antihypertensive medications. A total of 2208 adults were assessed. The prevalence of hypertension was 38.5%, and the age- and gender-adjusted prevalence was 37.0%. The proportion of patients who were aware of their hypertension among those diagnosed with hypertension was 24.8%. Of those aware of having hypertension, 23.6% took antihypertensive drugs. Among all hypertensive patients, only 7.2% had controlled their hypertension (<140/90 mmHg). Risk factors for hypertension were older age, smoking, alcohol consumption, family history of high blood pressure, overweight, and obesity. Protective factors included being slim and higher education. Hypertension was highly prevalent among this population of the Yi ethnic group in China. The ratio of awareness, treatment, and control of hypertension were considerately low. Hypertension education and screening programs in rural China are recommended to improve the health status of this population.

The influence of the sociodemographic context of one's environment on cognitive ageing is not well understood. We examined differences in cognitive trajectories according to the racial/ethnic characteristics of the residential environment. On the basis of 63 996 person-years of data from a nationally representative cohort of 6150 adults over the age of 50 years from the Health and Retirement Study, we used multivariate linear mixed models to determine the effect of neighbourhood racial/ethnic composition and county-level segregation on cognitive function and cognitive decline over a 10-year period. In models adjusting for individual demographic and health characteristics, Hispanic composition had a significant positive association with cognitive function (standardised β=0.136, p<0.05) and moderate evidence of an association with greater cognitive decline (standardised β=-0.014, p=0.09). Greater Hispanic-white segregation was associated with statistically significant higher cognitive function at baseline (standardised β=0.099, p<0.001) and greater cognitive decline (standardised β=-0.011, p<0.01). For a 20 percentage-point increase in Hispanic composition and segregation, the observed associations implied 1 and 1.25 additional years of cognitive ageing over 10 years, respectively. These effects did not differ by individual race/ethnicity and were not explained by neighbourhood socioeconomic status or neighbourhood selection. Black composition and black-white segregation did not have a significant influence on cognitive ageing. This study demonstrates disparities in the progression of cognitive ageing according to racial/ethnic characteristics of the neighbourhood environment. Published by the BMJ Publishing Group Limited.

Recent years have seen a global trend of declining immunization rates of recommended vaccines that is more pronounced among school-age children. Ethnic disparities in child immunization rates have been reported in several countries. We investigated an effect of ethnicity on the vaccination rates of immunizations routinely administered within schools in Israel. Data were collected from the Ministry of Health database regarding immunization coverage for all registered Israeli schools (3736) in the years 2009-2011. Negative binomial regression was used to assess the association between school ethnicity and immunization coverage while controlling for school characteristics. The lowest immunization coverage was found in Bedouin schools (median values of 75.1%, 81.5% and 0% for the first, second and eighth grades, respectively) in 2011. During this year, vaccination coverage in the first and second grades in Jewish schools was 1.51 and 1.35 times higher, respectively, compared to Bedouin schools. In the years 2009 and 2010, no significant increase in risk for lower vaccination rate was observed in Bedouin schools, and children in Arab and Druze schools were more likely to have been vaccinated. The lower vaccination refusal rate found in Bedouin schools supports the hypothesis that difficulties related to accessibility constitute the main problem rather than noncompliance with the recommended vaccination protocol for school-age children, featuring higher socio-economic status groups. Our study emphasizes the importance of identifying, beyond the national-level data, subpopulation groups at risk for non-vaccination. This knowledge is essential to administrative-level policy-makers for the allocation of resources and the planning of intervention programs.

Design Population-based, cross-sectional study. Participants We included 5887 persons aged 45 to 84 years with gradable AMD. Methods Digital fundus photographs were used to measure AMD. Two years earlier, biomarkers of inflammation were measured and history of inflammatory disease and use of antiinflammatory agents obtained. Main Outcome Measure Prevalence of AMD. Results While controlling for age, gender, race/ethnicity, and study site, there were no associations between systemic inflammatory factors and AMD severity. Higher levels of high-sensitivity C-reactive protein (odds ratio [OR] per standard deviation [SD] increase in natural log [ln] units, 2.34; 95% confidence interval [CI], 1.33–4.13) and interleukin-6 (OR per SD in ln, 2.06; 95% CI, 1.21–3.49) were associated with geographic atrophy but not other AMD end points. History of periodontal disease (OR, 1.68; 95% CI, 1.14–2.47) was related to increased retinal pigment. A history of arthritis was associated with soft distinct drusen (OR, 1.24; 95% CI, 1.06–1.46). A history of oral steroid use was related to large drusen (OR, 2.13; 95% CI, 1.14–3.97) and soft distinct drusen (OR, 1.76; 95% CI, 1.00–3.10) and history of cyclooxygenase 2 inhibitor use were associated with large drusen (OR, 1.50; 95% CI, 1.10–2.04), soft indistinct drusen (OR, 1.84; 95% CI, 1.09–3.10), and large drusen area (OR, 1.66; 95% CI, 1.02–2.71). Whites, blacks, and Hispanics with CFH Y402H CC variant genotype had the highest frequency of early AMD compared with those with wild TT genotype. The frequency of CFH did explain some of the difference in AMD prevalence between Chinese and Hispanics compared with whites, but did not explain the difference in prevalence

We examined the contribution of socioeconomic disadvantage and traumatic life events to ethnic disparities in disability among Israeli adults. We used data from the Survey of Health, Aging and Retirement in Europe (SHARE-Israel), a sample of Israeli adults aged 50 or older (N = 1,546). Disability measures included functional limitations, limitations in activities of daily living (ADL), and limitations in instrumental activities of daily living (IADL). Arabs and immigrants from the Former Soviet Union (FSU) experienced higher rates of functional limitations and limitations in IADLs compared to veteran Jews. The rate of having limitations in ADLs was similar for Arabs and veteran Jews, but was higher for FSU immigrants compared to veteran Jews. Inclusion of education, income, and traumatic life events attenuated, but did not eliminate ethnic disparities in disability. Identifying factors driving ethnic health disparities in Israel is imperative if we hope to achieve health equity.

There is paucity of studies examining suicide rates in narrow five-year age-bands after the age of 60 years. This study examined suicide rates in eight five-year age-bands between the age of 60 and 99 years because this will allow more precise comparison between the young old (60-79 years) and the oldest old (80+ years) age groups. Data on the number of suicides (International Classification of Diseases - ICD-10 codes, X60-84) in each of the eight five-year age-bands between the age-bands 60-64 years and 95-99 years in both gender for as many years as possible from 2000 were ascertained from three sources: colleagues with access to national data, national statisics office websites and email contact with the national statistics offices. The population size for the corresponding years and age-bands was estimated for each country using data provided by the United Nations website. In men, suicide rates continued to increase for each of the seven five-year age-bands from 60-64 years to 90-94 years age-band, and then declined slightly for the 95-99 year age-band. In women, suicide rates continued to increase for each of the six five-year age-bands from 60-64 years to 85-89 years age-bands, and then declined slightly for the 90-94 years and 95-99 years age-bands. The overall global suicide rates for each of the eight five-year age-bands are sufficiently large for them to constitute a public health concern. This is especially important given the ongoing rise in the elderly population size and the paucity of data on risk and protective factors for suicide in the five-year age-bands after the age of 60 years.

Objective To report population-based prevalence of hearing impairment based on speech recognition in noise testing in a large and inclusive sample of UK adults aged 40 to 69 years. The present study is the first to report such data. Prevalence of tinnitus and use of hearing aids is also reported. Design The research was conducted using the UK Biobank resource. The better-ear unaided speech reception threshold was measured adaptively using the Digit Triplet Test (n = 164,770). Self-report data on tinnitus, hearing aid use, noise exposure as well as demographic variables were collected. Results Overall, 10.7% of adults (95%CI 10.5–10.9%) had significant hearing impairment. Prevalence of tinnitus was 16.9% (95%CI 16.6–17.1%) and hearing aid use was 2.0% (95%CI 1.9–2.1%). Odds of hearing impairment increased with age, with a history of work- and music-related noise exposure, for lower socioeconomic background and for ethnic minority backgrounds. Males were at no higher risk of hearing impairment than females. Conclusion Around 1 in 10 adults aged 40 to 69 years have substantial hearing impairment. The reasons for excess risk of hearing impairment particularly for those from low socioeconomic and ethnic minority backgrounds require identification, as this represents a serious health inequality. The underutilization of hearing aids has altered little since the 1980s, and is a major cause for concern. PMID:24518430

This study examined how adiposity influences racial/ethnic differences in diabetes incidence by exploring whether relations between anthropometric measures and incident diabetes vary by race/ethnicity. Data from the Multi-Ethnic Study of Atherosclerosis initiated in 2000 (n = 5,446 US men and women aged 45–84 years) were analyzed by using proportional hazards and Poisson regression. The diabetes incidence rate was 2/100 person-years (n = 479 cases). Interactions were present between race and anthropometry (P-interaction(race × body mass index) = 0.002). The slope of incident diabetes per anthropometric unit was greatest for Chinese, less for whites and Hispanics, and still less for blacks. For small waist, risk of incident diabetes was <1/100 person-years for all racial/ethnic groups. At intermediate waist levels, Chinese had the highest and whites the lowest rates of incident diabetes. At the respective 95th percentiles of waist circumference, risk of incident diabetes per 100 person-years was 3.9 for Chinese (104 cm), 3.5 for whites (121 cm), 5.0 for blacks (125 cm), and 5.3 for Hispanics (121 cm). Adiposity influenced relative diabetes occurrence across racial/ethnic groups, in that Chinese had a steeper diabetes risk per unit of adiposity. However, the generally low level of adiposity in Chinese led to a relatively low diabetes occurrence. PMID:20570825

Objectives. In this prospective cohort study, we examined the trajectory of general health during the first 4 years after new immigrants’ arrival in Canada. We focused on the change in self-rated health trajectories and their gender and ethnic disparities. Methods. Data were derived from the Longitudinal Survey of Immigrants to Canada and were collected between April 2001 and November 2005 by Statistics Canada. We used weighted samples of 3309 men and 3351 women aged between 20 and 59 years. Results. At arrival, only 3.5% of new immigrants rated their general health as poor. Significant and steady increases in poor health were revealed during the following 4 years, especially among ethnic minorities and women. Specifically, we found a higher risk of poor health among West Asian and Chinese men and among South Asian and Chinese women than among their European counterparts. Conclusions. Newly arrived immigrants are extremely healthy, but the health advantage dissipates rapidly during the initial years of settlement in Canada. Women and minority ethnic groups may be more vulnerable to social changes and postmigration settlement. PMID:23409893

To evaluate whether African American ethnicity is a risk factor for major respiratory complications following adenotonsillectomy (T&A). Retrospective cohort study. A Canadian tertiary care center. PATIENTS Children aged 0 to 18 years who underwent T&A at our institution from 2002 to 2006 with planned or unplanned postoperative admissions. We evaluated the association between ethnicity and our main outcome measure, major perioperative respiratory complications of T&A. Parental report of ethnicity was available for 23% of our cohort. At our institution, African American children undergo a routine preoperative sickle cell test (TestSC). Data on TestSC were included for all children. We established that having a TestSC was an accurate proxy for African American ethnicity (sensitivity, 96%; specificity, 93%; positive predictive value, 77%; negative predictive value, 99%). Seventy-four of 594 children experienced major respiratory complications (12.5%). Compared with children who did not have major respiratory complications, those who did had a TestSC (P = .01), were 2 years or younger (P < .001) and had lower weight-for-age z scores (P = .04), moderate to severe obstructive sleep apnea (P = .003), and comorbidities (P < .001). When controlling for these variables in a multivariate analysis, children of African American ethnicity (TestSC used as a proxy) were at higher risk of having major perioperative respiratory complications (adjusted odds ratio, 1.82 [95% CI 1.05-3.14]) (P = .003). Children of African American ethnicity (TestSC used as a proxy) are nearly twice as likely to experience major respiratory complications related to T&A. Ethnicity may be an additional independent risk factor for clinicians to consider when planning for T&A.

INTRODUCTION This study aimed to develop and validate a food frequency questionnaire (FFQ) to assess habitual diets of multi-ethnic Malaysian children aged 7–12 years. METHODS A total of 236 primary school children participated in the development of the FFQ and 209 subjects participated in the validation study, with a subsample of 30 subjects participating in the reproducibility study. The FFQ, consisting of 94 food items from 12 food groups, was compared with a three-day dietary record (3DR) as the reference method. The reproducibility of the FFQ was assessed through repeat administration (FFQ2), seven days after the first administration (FFQ1). RESULTS The results of the validation study demonstrated good acceptance of the FFQ. Mean intake of macronutrients in FFQ1 and 3DR correlated well, although the FFQ intake data tended to be higher. Cross-classification of nutrient intake between the two methods showed that < 7% of subjects were grossly misclassified. Moderate correlations noted between the two methods ranged from r = 0.310 (p < 0.001) for fat to r = 0.497 (p < 0.001) for energy. The reproducibility of the FFQ, as assessed by Cronbach’s alpha, ranged from 0.61 (protein) to 0.70 (energy, carbohydrates and fat). Spearman’s correlations between FFQ1 and FFQ2 ranged from rho = 0.333 (p = 0.072) for protein to rho = 0.479 (p < 0.01) for fat. CONCLUSION These findings indicate that the FFQ is valid and reliable for measuring the average intake of energy and macronutrients in a population of multi-ethnic children aged 7–12 years in Malaysia.

Gross and important inequities have historically existed in the oral health profiles of New Zealand children. Following the New Zealand Government's strategic oral health vision, launched in 2006, nationally collected information from 2004 to 2013 was used to analyze patterns in the prevalence of no obvious decay experience (caries-free) and mean decayed-missing-filled teeth indices over time and by community water fluoridation (CWF) and ethnic classifications in New Zealand children aged 5 years and in school year 8 (generally aged 12-13 years). National aggregated data collected from children's routine child oral health service dental examinations were retrieved, and combined with demographic information from Statistics New Zealand. Children's CWF status was defined by the public water supply status of their school. Crude and standardized population estimates of caries-free prevalence and mean decayed-missing-filled teeth indices over time were derived. Unweighted linear regression models of main effects and two-factor interactions were investigated by age group. Dental examination data were available from 417,318 children aged 5 years and 471,333 year 8 children; of whom 93,715 (22.5 %) and 94,001 (19.9 %), respectively, were Māori. Dental examination coverage of Māori children was significantly less than their non-Māori counterparts (approximately 11 % and 14 % for aged 5 and year 8 children, respectively). Regression analysis revealed that caries-free prevalence and mean decayed-missing-filled teeth indices significantly improved over the study period for both age groups. Significant and sustained differences were observed between Māori and non-Māori children, and between CWF and non-CWF exposed groups. However, a convergence of dental profiles between non-Māori children in CWF and non-CWF regions was observed. Significant and important gains in New Zealand children's oral health profiles appear to have been made over the last decade. Māori children

Associations of physical activity with all-cause mortality seem to be quite strong, but little is known about potential effect modifiers as sex, race/ethnicity, age, and obesity. Data of the Third National Health and Nutrition Examination Survey (NHANES III), conducted 1988-1994 with mortality follow-up until 2006, were used to compare mortality risk between different levels of leisure-time physical activity (LTPA) and occupational physical activity (OPA). Cox proportional hazards models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs). LTPA (n = 15,307) was inversely associated with all-cause mortality (HR 0.75, 95% CI 0.64-0.88 for regular vs. no LTPA). There was a statistically significant interaction with age (P = .03), with participants over 60 years of age benefitting more from regular or irregular LTPA. OPA was positively associated with all-cause mortality (HR 1.25, 95% CI 0.85-1.84 for high vs. low OPA), particularly among Mexican-Americans (HR 2.28, 95% CI 1.23-4.22); statistically significant interactions were observed for obesity and gender. LTPA clearly predicts all-cause mortality. However, associations between OPA and all-cause mortality are unclear and need further research with special regard to ethnic differences.

The aim of this study was to determine the association of anti-Sm antibodies with clinical manifestations, comorbidities, and disease damage in a large multi-ethnic SLE cohort. SLE patients (per American College of Rheumatology criteria), age ≥16 years, disease duration ≤10 years at enrollment, and defined ethnicity (African American, Hispanic or Caucasian), from a longitudinal US cohort were studied. Socioeconomic-demographic features, cumulative clinical manifestations, comorbidities, and disease damage (as per the Systemic Lupus International Collaborating Clinics Damage Index [SDI]) were determined. The association of anti-Sm antibodies with clinical features was examined using multivariable logistic regression analyses adjusting for age, gender, ethnicity, disease duration, level of education, health insurance, and smoking. A total of 2322 SLE patients were studied. The mean (standard deviation, SD) age at diagnosis was 34.4 (12.8) years and the mean (SD) disease duration was 9.0 (7.9) years; 2127 (91.6%) were women. Anti-Sm antibodies were present in 579 (24.9%) patients. In the multivariable analysis, anti-Sm antibodies were significantly associated with serositis, renal involvement, psychosis, vasculitis, Raynaud's phenomenon, hemolytic anemia, leukopenia, lymphopenia, and arterial hypertension. No significant association was found for damage accrual. In this cohort of SLE patients, anti-Sm antibodies were associated with several clinical features including serious manifestations such as renal, neurologic, and hematologic disorders as well as vasculitis.

There is evidence of racial/ethnic differences in the age at which young adults age out of heavy drinking. Some studies have found Black and Hispanic drinkers engage in more frequent heavy drinking than White people beyond adulthood. Yet, the alcohol-related disparities literature has produced contradictory findings on whether an age-crossover effect is evident among racial/ethnic groups; that is, whether racial/ethnic minorities' drinking levels or trajectories are lower than White people at young ages but later exceed (or crossover) those of White people. This study extends this scant literature by assessing whether racial/ethnic differences in heavy drinking have changed over time (possibly accounting for mixed findings from prior research); and tests for an age-crossover effect in heavy drinking using longitudinal data from 2 cohorts born 20 years apart. Data are from the 1979 (n = 10,963) and 1997 (n = 8,852) cohorts of the National Longitudinal Survey of Youth (NLSY). Generalized estimating equations were used to model trajectories of heavy drinking frequency from ages 17 to 31. Racial/ethnic differences were determined using sex-stratified models and 3-way interactions of race/ethnicity with age, age-squared, and cohort. Racial/ethnic differences in heavy drinking trajectories have changed over time in men and women. In the older NLSY cohort, Hispanic men and Black women surpassed White men's and women's heavy drinking frequency by age 31. This crossover was absent in the younger cohort, where trajectories of all racial-sex groups converged by age 31. Normative trajectories have changed in Hispanics and White people of both sexes, with a delay in age of peak frequency, and greater levels of heavy drinking in the younger cohort of women. Changes in heavy drinking trajectories over time suggest the need for targeted interventions during young adulthood. While disparities in young adult heavy drinking were no longer apparent in the more recent birth cohort

Approximately 25% of working-aged Americans with disabilities work full or part time, yet still face discrimination despite the passing of the American's with Disabilities Act (ADA) over 20 years ago. To determine if the proportion of allegations of ADA Title I workplace discrimination with merit closed at any year between 1993 and 2008 differs among Whites, African Americans, Hispanics, and Asians; to determine if there was a change over time from 1993 to 2008 in merit closure rate within each race/ethnicity group; and to determine whether changes over time between 1993 and 2008 in the merit closure rate differ among the race/ethnicity groups. Logistic regression was used for this cross-sectional panel study to model the merit closure rate for each ethnic group from 1993 to 2008 using 318,587 charging parties from the EEOC database. All ethnic groups exhibited significant changes over time in the merit closure rate. There were significant differences in the closure rates among the race/ethnicity groups specifically at closure years 1995-2000, 2002, 2003, and 2006. Finally, there was evidence that the trends in merit closure rates over time differed significantly among the race/ethnicity groups. There was significant evidence that the proportion of claims closed with merit was significantly different among the racial/ethnicity groups.

To describe the ethnic differences in central corneal thickness (CCT) in population-based samples of ethnic Bai, Yi and Han people living in rural China. 6504 adults (2119 ethnic Bai, 2202 ethnic Yi and 2183 ethnic Han) aged 50 years or older participated in the study. Each subject underwent standardized ocular examinations and interviewer-administered questionnaires for risk factor assessment. CCT was measured for both eyes using an ultrasound pachymeter. Regression and principal component analysis were performed to examine the relationship of ethnicity and other factors with CCT. The mean CCT readings were 536.4 ± 34.2 μm in ethnic Bai, 532.1 ± 32.1 μm in ethnic Yi and 529.6 ± 32.7 μm in ethnic Han adults (P<0.001), respectively. There was a decreasing trend of mean CCT with increasing age across all ethnic groups. In multivariate linear regression models, increasing CCT was associated with younger age (P<0.001), male gender (P<0.001), Bai (P<0.001) or Yi (P<0.001) ethnicity, greater body mass index (P<0.001), higher systolic blood pressure (P<0.001), greater corneal curvature (P<0.001), deeper anterior chamber (P < 0.001), and thicker lens (P<0.001). Ethnicity contributed significantly to presence of thin cornea (60%; P< 0.001) compared with other factors. CCT had similar impact on intraocular pressure readings across all ethnic groups. This study of more than 6500 multiethnic participants demonstrates significant ethnic variations in CCT, with Han ethnicity having the thinnest cornea compared with ethnic minorities. These data are essential to guide future multiethnic clinical trials on CCT-related ocular conditions such as glaucoma.

The ethnic and racial structuring of U.S. neighborhoods may have important implications for developmental competencies during adolescence, including the development of heritage and mainstream cultural orientations. In particular, living in highly concentrated Latino neighborhoods during early adolescence-which channels adolescents into related school environments-may promote retention of the ethnic or heritage culture, but it also may constrain adaptation to the mainstream U.S. culture. We tested these hypotheses longitudinally in a sample of 246 Mexican origin adolescents (50.8% girls) and their parents. Data were collected 4 times over 8 years, with adolescents averaging 12.5 (SD = .58) to 19.6 (SD = .66) years of age across the period of the study. Latino ethnic concentration in early adolescents' neighborhoods promoted the retention of Mexican cultural orientations; Latino ethnic concentration in middle schools undermined the development of mainstream U.S cultural orientations. Findings are discussed in terms of integrating cultural-developmental theory with mainstream neighborhood theory to improve understandings of neighborhood and school ethnic concentration effects on adolescent development.

Objective To assess developmental trends in physical activity and sedentary behaviour in British adolescents in relation to sex, ethnicity and socioeconomic status (SES). Design A 5‐year longitudinal study of a diverse cohort of students aged 11–12 years at baseline in 1999. Setting 36 London schools sampled using a stratified random sampling procedure. Participants A total of 5863 students categorised as white, black or Asian, and stratified for SES using the Townsend Index. Main outcome measures Number of days per week of vigorous activity leading to sweating and breathing hard. Hours of sedentary behaviour, including watching television and playing video games. Data were analysed using multilevel, linear, mixed models. Results Marked reductions in physical activity and increases in sedentary behaviour were noticed between ages 11–12 and 15–16 years. Boys were more active than girls, and the decline in physical activity was greater in girls (46% reduction) than in boys (23%). Asian students were less active than whites, and this was also true of black girls but not boys. Black students were more sedentary than white students. Levels of sedentary behaviour were greater in respondents from lower SES. Most differences between ethnic and SES groups were present at age 11 years, and did not evolve over the teenage years. Conclusions Physical activity declines and sedentary behaviour becomes more common during adolescence. Ethnic and SES differences are observed in physical activity and sedentary behaviour in British youth that anticipate adult variations in adiposity and cardiovascular disease risk. These are largely established by age 11–12 years, so reversing these patterns requires earlier intervention. PMID:17178773

To describe the methodology utilized to evaluate cognitive function in the Multi-Ethnic Study of Atherosclerosis (MESA) and to present preliminary results by age, sex, and race/ethnicity. Cross-sectional measurements of a prospective observational cohort. Residents of 6 U.S. communities free of cardiovascular disease at baseline (2000-02). 4,591 adults who completed the fifth MESA clinical examination in 2011-12; mean age 70.3 (SD: 9.5) years, 53.1% women, 40.7% non-Hispanic white, 26.4% non-Hispanic black, 21.4% Hispanic, and 11.5% Chinese. The cognitive battery consisted of the Cognitive Abilities Screening Instrument (version 2) to evaluate global cognition, the Digit Symbol Code for processing speed and Digit Spans Forward and Backward to assess memory. Demographic, socioeconomic, and cultural covariates were also collected for descriptive statistics and multivariate modeling. Associations between socioeconomic factors and cognition revealed that age, race/ethnicity, education, occupational status, household income, health insurance type, household size, place of birth, years and generation in U.S., and the presence of the ApoE4 allele were significantly associated with performance on the cognitive tests, although patterns varied by specific test, racial/ethnicity, and sociocultural factors. As many of the influencing cultural and socioeconomic factors measured here are complex, multifactorial, and may not be adequately quantified, caution has been recommended with regard to comparison and interpretation of racial/ethnic group performance differences from these cross-sectional models. These data provide a baseline for future exams and more comprehensive longitudinal analyses of the contributions of subclinical and clinical diseases to cognitive function and decline.

Participants 4,591 adults who completed the 5th MESA clinical examination in 2011-12, mean age 70.3 (SD 9.5) years, 53.1% women, and 40.7% Non-Hispanic White, 26.4% Non-Hispanic Black, 21.4% Hispanic, and 11.5% Chinese. Measurements The cognitive battery consisted of the Cognitive Abilities Screening Instrument (version 2) to evaluate global cognition, the Digit Symbol Code for processing speed and Digit Spans Forward and Backward to assess memory. Demographic, socioeconomic, and cultural covariates were also collected for descriptive statistics and multivariate modeling. Results Associations between socio-economic factors and cognition revealed that age, race/ethnicity, education, occupational status, household income, health insurance type, household size, place of birth, years and generation in U.S., and the presence of the APOE4 allele were significantly associated with performance on the cognitive tests although patterns varied by specific test, racial/ethnicity, and socio-cultural factors. Conclusions As many of the influencing cultural and socioeconomic factors measured here are complex, multifactorial, and may not be adequately quantified, caution has been recommended with regard to comparison and interpretation of racial/ethnic group performance differences from these cross-sectional models. These data provide a baseline for future exams and more comprehensive longitudinal analyses of the contributions of subclinical and clinical diseases to cognitive function and decline. PMID:25704999

To investigate the epidemiological status of glucose-6-phosphate dehydrogenase (G6PD) deficiency among children from Yunnan with unique ethnic origins. DNA samples from 11759 children were tested with fluorescent spot test, G6PD/6PGD quantitative ratio assay and hemoglobin electrophoresis. The detection rate of G6PD deficiency was 2.5%, for which boys were significantly greater than girls (3.5% vs. 1.4%, P<0.05). Significant differences were also detected among children from different ethnic groups and different regions. For ethnic Han Chinese, the detection rate was 0.7%, which was lower than the majority of ethnic minorities. By regression analysis, altitude of residence and family history both have significant influence on the calculated rate. Occurrence of G6PD deficiency seems to be influenced by gender. It also varies substantially between different ethnic groups as well as regions, e.g., more common in south. It also showed a declining trend after years of diagnosis and intervention. This survey may provide a valuable basis for counseling of G6PD deficiency in Yunnan.

The National Health and Nutrition Examination Survey (NHANES) is a nationally representative, population-based survey designed to assess the health and nutritional status of the civilian, non-institutionalized US population. Data were collected through a personal interview regarding health history and through physical examination. Earlier NHANES surveys were conducted on a periodic basis; however, in 1999, NHANES began collecting data on a continuing, annual basis. During NHANES I, which ran from 1971-1975, audiometric testing was conducted on adults aged 25-74 years. No subsequent testing of adults was conducted in the NHANES program until 1999, when NHANES began audiometric testing of adults aged 20-69 years. This report examines the hearing levels for adults in the United States and compares them with the hearing data from NHANES I. Hearing levels are grouped by age and are grouped by ethnicity and gender.

Various environmental factors have been associated with the timing of eruption of primary dentition, but the evidence to date comes from small studies with limited information on potential risk factors. We aimed to investigate associations between tooth emergence patterns and pre-conception, pregnancy and post-natal influences. Dentition patterns were recorded at ages one and two years in 2,915 children born to women in the Southampton Women’s Survey from whom information had been collected on maternal factors before conception and during pregnancy. In mutually adjusted regression models we found that: children were more dentally advanced at ages one and two years if their mothers had smoked during pregnancy or they were longer at birth; mothers of children whose dental development was advanced at age two years tended to have poorer socioeconomic circumstances, and to have reported a slower walking speed pre-pregnancy; and children of mothers of Asian ethnicity had later tooth development than those of white mothers. The findings add to the evidence of environmental impacts on the timing of the eruption of primary dentition in indicating that maternal smoking during pregnancy, socio-economic status and physical activity (assessed by reported walking speed) may influence the child’s primary dentition. Early life factors, including size at birth are also associated with dentition patterns, as is maternal ethnicity. PMID:25936832

There are huge regional disparities in under-five mortality in Nigeria. While a region within the country has as high as 222 under-five deaths per 1000 live births, the rate is as low as 89 per 1000 live births in another region. Nigeria is culturally diverse as there are more than 250 identifiable ethnic groups in the country; and various ethnic groups have different sociocultural values and practices which could influence child health outcome. Thus, the main objective of this study was to examine the ethnic differentials in under-five mortality in Nigeria. The study utilized 2008 Nigeria Demographic and Health Survey (NDHS) data. We analyzed data from a nationally representative sample drawn from 33,385 women aged 15-49 that had a total of 104,808 live births within 1993-2008. In order to examine ethnic differentials in under-five mortality over a sufficiently long period of time, our analysis considered live births within 15 years preceding the 2008 NDHS. The risks of death in children below age five were estimated using Cox proportional regression analysis. Results were presented as hazard ratios (HR) with 95% confidence intervals (CI). The study found substantial differentials in under-five mortality by ethnic affiliations. For instance, risks of death were significantly lower for children of the Yoruba tribes (HR: 0.39, CI: 0.37-0.42, p < 0.001), children of Igbo tribes (HR: 0.58, CI: 0.55-0.61, p < 0.001) and children of the minority ethnic groups (HR: 0.66, CI: 0.64-0.68, p < 0.001), compared to children of the Hausa/Fulani/Kanuri tribes. Besides, practices such as plural marriage, having higher-order births and too close births showed statistical significance for increased risks of under-five mortality (p < 0.05). The findings of this study stress the need to address the ethnic norms and practices that negatively impact on child health and survival among some ethnic groups in Nigeria.

Existing studies evaluating racial and ethnic disparities focus on describing differences in procedure type and the proportion of women who undergo reconstruction following mastectomy. This study seeks to examine racial and ethnic variations in clinical and patient-reported outcomes (PROs) following breast reconstruction. The Mastectomy Reconstruction Outcomes Consortium is an 11 center, prospective cohort study collecting clinical and PROs following autologous and implant-based breast reconstruction. Mixed-effects regression models, weighted to adjust for non-response, were performed to evaluate outcomes at one-year postoperatively. The cohort included 2703 women who underwent breast reconstruction. In multivariable models, Hispanic or Latina patients were less likely to experience any complications and major complications. Black or African-American women reported greater improvements in psychosocial and sexual well-being. Despite differences in pertinent clinical and socioeconomic variables, racial and ethnic minorities experienced equivalent or better outcomes. These findings provide reassurance in the context of numerous racial and ethnic health disparities and build upon our understanding of the delivery of surgical care to women with or at risk for developing breast cancer.

Fractures are common in childhood, and there is considerable variation in the reported incidence across European countries, but few data relating to ethnic and geographic differences within a single country. We therefore aimed to determine the incidence of childhood fractures in the United Kingdom (UK), and to describe age-, ethnicity- and region- specific variations. The Clinical Practice Research Datalink (CPRD) contains anonymised electronic health records for approximately 7% of the UK population. The occurrence of a fracture between 1988 and 2012 was determined from the CPRD for all individuals <18years of age, and used to calculate fracture incidence rates for age, sex and ethnicity. Regional fracture incidence rates were also calculated based on general practitioner location within 14 Strategic Health Authorities (SHA) within the UK. The overall fracture incidence rate was 137 per 10,000 person-years (py). This was higher in boys (169 per 10,000 py) than girls (103 per 10,000 py) and white children (150 per 10,000 py) compared to those of black (64 per 10,000 py) and South Asian (81 per 10,000 py) ethnicity. Marked geographic variation in incidence was observed. The highest fracture rates were observed in Wales, where boys and girls had 1.82 and 1.97 times greater incidence, respectively, than those residing in Greater London. In the period 1988-2012, there was marked geographic and ethnic variation in childhood fracture incidence across the UK. These findings also implicate lifestyle and socio-economic differences associated with location and ethnicity, and are relevant to policy makers in the UK and internationally.

In this study we aimed to determine the maximal isometric muscle strength of a healthy, normal-weight, pediatric population between 6 and 15 years of age using hand-held dynamometry to establish strength reference values. The secondary objective was determining the relationship between strength and anthropometric parameters. Four hundred normal-weight Chilean children, split into 10 age groups, separated by 1-year intervals, were evaluated. Each age group included between 35 and 55 children. The strength values increased with increasing age and weight, with a correlation of 0.83 for age and 0.82 for weight. The results were similar to those reported in previous studies regarding the relationships among strength, age, and anthropometric parameters, but the reported strength differed. These results provide normal strength parameters for healthy and normal-weight Chilean children between 6 and 15 years of age and highlight the relevance of ethnicity in defining reference values for muscle strength in a pediatric population.

Jain, Ram B

2016-07-01

Using data from National Health and Nutrition Examination Survey for the period 2003-2012, the objective of this study was to evaluate trends in blood lead levels (BLL) among adults aged 20-64 years (adults) and seniors aged ≥65 years (seniors). In addition, the contribution of other factors like gender, race/ethnicity, smoking, and exposure to secondhand smoke at home in explaining variability in BLL was also evaluated by fitting regression models with log10 transformed values of BLL as dependent variables. BLL decreased over 2003-2012 (p < 0.01). Irrespective of gender, race/ethnicity, and smoking status, seniors were found to have higher BLL than adults. Based on the magnitude of differences between the 5th and 95th percentiles, variability in the levels of blood lead was found to be substantially higher among seniors than among adults. Males had statistically significantly higher adjusted BLL than females (2.32 vs. 1.76 μg/dL for seniors, p < 0.01 and 1.66 vs. 1.13 μg/dL for adults, p < 0.01). Non-Hispanic whites had statistically significantly lower adjusted BLL than non-Hispanic blacks (1.99 vs. 2.42 μg/dL for seniors, p < 0.01 and 1.22 vs. 1.42 μg/dL for adults, p < 0.01). When compared with non-smokers, smokers had statistically significantly higher BLL (2.19 vs. 1.86 μg/dL for seniors, p < 0.01 and 1.54 vs. 1.22 μg/dL for adults, p < 0.01). Non-obese had statistically significantly higher BLL than obese individuals (2.11 vs. 1.93 μg/dL for seniors, p < 0.01 and 1.48 vs. 1.27 μg/dL for adults, p < 0.01). Exposure to secondhand smoke at home (SHS) was associated with statistically significantly higher BLL than when there was no exposure to SHS (β = 0.0683, p = 0.03 for seniors; β = 0.034, p = 0.034, p < 0.01 for adults).

Assess MDS-UPDRS items for gender-, age-, and race/ethnicity-based differential item functioning. Assessing differential item functioning is a core rating scale validation step. For the MDS-UPDRS, differential item functioning occurs if item-score probability among people with similar levels of parkinsonism differ according to selected covariates (gender, age, race/ethnicity). If the magnitude of differential item functioning is clinically relevant, item-score interpretation must consider influences by these covariates. Differential item functioning can be nonuniform (covariate variably influences an item-score across different levels of parkinsonism) or uniform (covariate influences an item-score consistently over all levels of parkinsonism). Using the MDS-UPDRS translation database of more than 5,000 PD patients from 14 languages, we tested gender-, age-, and race/ethnicity-based differential item functioning. To designate an item as having clinically relevant differential item functioning, we required statistical confirmation by 2 independent methods, along with a McFadden pseudo-R 2 magnitude statistic greater than "negligible." Most items showed no gender-, age- or race/ethnicity-based differential item functioning. When differential item functioning was identified, the magnitude statistic was always in the "negligible" range, and the scale-level impact was minimal. The absence of clinically relevant differential item functioning across all items and all parts of the MDS-UPDRS is strong evidence that the scale can be used confidently. As studies of Parkinson's disease increasingly involve multinational efforts and the MDS-UPDRS has several validated non-English translations, the findings support the scale's broad applicability in populations with varying gender, age, and race/ethnicity distributions. © 2016 International Parkinson and Movement Disorder Society. © 2016 International Parkinson and Movement Disorder Society.

The objective of this study was to understand the features of young suicide in order to contribute to suicide prevention efforts. In this article, the demographic, clinical, and suicide-related features of all cases of young suicide (aged 10-24 years) in Singapore for the years 2000-2004 are described. We also compared those who sought mental health services to those who did not. Overall, the suicide rate was 5.7 per 100, 000, with gender ratio of 1:1 and higher rates among ethnic Indians. Psychosocial stressors and suicide by jumping from height were common. Mental health service use was associated with unemployment, previous suicide attempts, family history of suicide, more use of lethal methods, lack of identifiable stressor, and less suicide notes. Suicide prevention efforts should promote awareness of suicide risks and access to mental health services.

To determine the sex- and ethnicity-specific prevalence of color vision deficiency (CVD) in black, Asian, Hispanic, and non-Hispanic white preschool children. Population-based, cross-sectional study. The Multi-Ethnic Pediatric Eye Disease Study is a population-based evaluation of the prevalence of vision disorders in children in Southern California. A total of 5960 subjects 30 to 72 months of age were recruited for the study, of whom 4177 were able to complete color vision testing (1265 black, 812 Asian, 1280 Hispanic, and 820 non-Hispanic white). Color vision testing was performed using Color Vision Testing Made Easy color plates (Home Vision Care, Gulf Breeze, FL), and diagnostic confirmatory testing was performed using the Waggoner HRR Diagnostic Test color plates (Home Vision Care). Testability of color vision in preschool children between 30 and 72 months of age and prevalence of CVD stratified by age, sex, and ethnicity. Testability was 17% in children younger than 37 months of age, increasing to 57% in children 37 to 48 months of age, 89% in children 49 to 60 months of age, and 98% in children 61 to 72 months of age. The prevalence of CVD among boys was 1.4% for black, 3.1% for Asian, 2.6% for Hispanic, and 5.6% for non-Hispanic white children; the prevalence in girls was 0.0% to 0.5% for all ethnicities. The ethnic difference in CVD was statistically significant between black and non-Hispanic white children (P = 0.0003) and between Hispanic and non-Hispanic white children (P = 0.02). In boys, most CVD cases were either deutan (51%) or protan (34%); 32% were classified as mild, 15% as moderate, and 41% as severe. Testability for CVD in preschool children is high by 4 years of age. The prevalence of CVD in preschool boys varies by ethnicity, with the highest prevalence in non-Hispanic white and lowest in black children. Copyright © 2014 American Academy of Ophthalmology.

The current study examined the longitudinal associations between family ethnic socialization and youths’ ethnic identity among a sample of Mexican-origin youth (N = 178, Mage = 18.17, SD = .46). Findings from multiple-group cross lagged panel models over a two year period indicated that for U.S.-born youth with immigrant parents, the process appeared to be family-driven: Youths’ perceptions of family ethnic socialization in late adolescence were associated with significantly greater ethnic identity exploration and resolution in emerging adulthood, while youths’ ethnic identity during late adolescence did not significantly predict youths’ future perceptions of family ethnic socialization. Conversely, for U.S.-born youth with U.S. born parents, youths’ ethnic identity significantly predicted their future perceptions of family ethnic socialization but perceptions of family ethnic socialization did not predict future levels of youths’ ethnic identity, suggesting a youth-driven process. Findings were consistent for males and females. PMID:23421841

This study explored ethnic inequalities in dental caries among adults and assessed the role of socioeconomic position (SEP) in explaining those inequalities. We analysed data on 2013 adults aged 16-65 years, from the East London Oral Health Inequality (ELOHI) Study, which included a random sample of adults and children living in East London in 2009-10. Participants completed a questionnaire and were clinically examined for dental caries at home. Dental caries was measured using the number of decayed, missing and filled teeth or DMFT index. Ethnic inequalities in dental caries were assessed in negative binomial regression models before and after adjustment for demographic (sex and age groups) and SEP measures (education and socioeconomic classification). White Eastern European and White Other had higher DMFT, whereas all Asian (Pakistani, Indian, Bangladeshi and Other) and all Black (African, Caribbean and Other) ethnic groups had lower DMFT than White British. Similar inequalities were found for the number of filled and missing teeth, but there were no differences in the number of decayed teeth between ethnic groups. This study showed considerable disparities in dental caries between and within the major ethnic categories, which were independent of demographics and SEP. © The Author 2015.

2013-11-01

In the run-up to the 2012 London Olympics, the sense of national identity was salient. We tested children (N = 401) aged 5-15 years living near the Olympic site on national (British) and ethnic identification, national ingroup and outgroup attitudes, and sport participation. It was found that the strength of British identification peaked at age 9 years, but the strength of ethnic identification remained stable with age. Both liking for, and stereotyping of, different national groups diverged from age 9 years, but whilst stereotyping remained diverged liking converged by 15 years. The in group was one of the most liked, but one of the least positively stereotyped groups. Sport participation declined with age and was higher among boys, whilst the lowest socio-economic group showed the greatest discrepancy between normal and recent reported participation. The strength of British identification was associated with liking for, and stereotyping of, the British as well as sport participation, but the degree of associations varied between different groups of children. © 2013 The British Psychological Society.

To determine whether the prevalence of diagnosed diabetes in the greater Auckland Region varies by General Electoral District (GED). Using encrypted National Health Identifiers and record linkage of routine health datasets, we identified a regional cohort of people with diagnosed diabetes in 2011 from inpatient records and medication dispensing. The geographical unit of a person's residence (meshblock) was used to determine the GED of residence. We calculated prevalence estimates and 95% confidence intervals and used binary logistic regression to map geographical variations in diabetes. An estimated 63,014 people had diagnosed diabetes in Auckland in 2011, a prevalence of 8.5% of the adult population ≥30 years of age. We found significant variation in diabetes prevalence by age, gender, ethnicity and GED. There was a more than five-fold difference in the unadjusted prevalence of diabetes by GED, ranging from 3.2% (3.1 to 3.4%) in the North Shore to 17.3% (16.8 to 17.7%) in Mangere. Such variations remained after binary logistic regression adjusting for socio-demographic variables. Compared to New Zealand Europeans, Indian people had the highest odds of having diabetes at 3.85 (3.73 to 3.97), while the odds of people living in the most deprived areas having diabetes was nearly twice that of those living in least deprived areas (OR 1.93, [1.87 to 1.99]). Geographic variations in diabetes remained after adjusting for socio-demographic circumstances: people living in GEDs in south-west Auckland were at least 60% more likely than people living in the North Shore GED to have diabetes. There is significant variation in the prevalence of diabetes by GED in Auckland that persists across strata of age group, gender and ethnicity, and persists after controlling for these same variables. These inequities should prompt action by politicians, policymakers, funders, health providers and communities for interventions aimed at reducing such inequities. Geography and its

The present study examined direct and interactive links between friendships and social, academic, and psychological adjustment problems (i.e., peer rejection as nominated by same-ethnic and cross-ethnic peers, teacher-reported academic engagement, and teacher-reported internalizing symptoms) among school-age children in multiethnic schools (n = 509, age: 9-10). The data, which included 2 time points with a 6-month interval, were drawn from a relatively large-sized, short-term longitudinal study. Results showed that cross-ethnic friendships (not same-ethnic friendships) were associated with greater academic engagement concurrently and predated decreased peer rejection and internalizing symptoms longitudinally, even after controlling for the availability of same-ethnic peers and classroom diversity. Furthermore, cross-ethnic friendships (not same-ethnic friendships) moderated the link between relational victimization and increased peer rejection and greater internalizing symptoms, such that this link was evidenced for children with fewer cross-ethnic friendships. However, the moderation effect was contingent upon the type of outcome variables and the ethnicity of the child. For example, the buffering effect against the negative contribution of relational victimization to internalizing symptoms was found particularly for African American children. The findings are discussed based on theories of normative development, ethnic socialization, and intergroup relations. (c) 2015 APA, all rights reserved).

All ethnic groups in Malaysia have contributed to this modern demographic transition but the rate of change has been most rapid for Chinese and Indians, Malay fertility having reached a plateau in the early 1980s. The effect of age structure, marital patterns and marital fertility (by parity) on the fertility declines for each ethnic community are analyzed. There has been a tendency, in each ethnic group, for the age distribution within the group of reproductive-age women to grow younger, reflecting the entry into the younger reproductive ages of the large birth cohorts of the 1950s and early 1960s. The effect of this on crude birth rates is hard to determine, because rising age at marriage and increasing use of contraception meant that fertility was increasingly concentrated in the more central reproductive ages. By the 1990s, the earlier declines in fertility will bring about a decline in the proportion of the total population made up of females in the main reproductive ages. After that point, further declines in fertility will be reflected in a sharper decline in the crude birth rate and hence the rate of population increase. Between 1947 and 1980, the age at marriage changed dramatically for females of all ethnic groups. The transition to higher age at marriage for Chinese was completed earlier, and since 1970 has risen by only a year. For Malays and Indians, the rise began later, proceeded faster and continued right up to 1980 when the medium ages at 1st marriage were Malays 22, Indians 23, Chinese 24 years. In 1980, Malay women on average were marrying 5 years later, and Indian women 6 years later than had their mothers' generation in 1947. The proportion never-married among Malay and Indian women aged 20-24 rose from 1/10 to 1/2 over this period; relatively greater changes are evident at ages 25-29. Other factors are the almost

The NHS faces a crisis in terms of staffing and recruitment. Many of the ethnic minority GPs in inner city areas throughout the UK are coming up to retirement age, and there is an insufficient supply of trainees to fill estimated vacancies. Over 2,000 nursing vacancies exist across the UK, and recruitment to the profession and retention within the profession are poor. Nurses have been recruited from overseas for the past 40 years, and are currently being recruited from Finland, Malaysia, and the West Indies, whilst doctors are being sought in India, Pakistan and Africa. Overseas recruitment is not a new phenomenon, and numerous studies have been carried out to examine equal opportunities and racial discrimination within the NHS. The aim of this paper was to examine ethnicity and equal opportunities within the Scottish NHS and record the levels of organisational awareness of ethnicity and equal opportunities' issues. The paper also examines the link between health service delivery to ethnic minorities and internal cultural attitudes to staff.

The racial/ethnic composition of a neighborhood may be related to residents’ depressive symptoms through differential levels of neighborhood social support and/or stressors. We used the Multi-Ethnic Study of Atherosclerosis to investigate cross-sectional associations of neighborhood racial/ethnic composition with the Center for Epidemiologic Studies-Depression (CES-D) scale in adults aged 45–84. The key exposure was a census-derived measure of the percentage of residents of the same racial/ethnic background in each participant’s census tract. Two-level multilevel models were used to estimate associations of neighborhood racial/ethnic composition with CES-D scores after controlling for age, income, marital status, education and nativity. We found that living in a neighborhood with a higher percentage of residents of the same race/ethnicity was associated with increased CES-D scores in African American men (p < 0.05), and decreased CES-D scores in Hispanic men and women and Chinese women, although these differences were not statistically significant. Models were further adjusted for neighborhood-level covariates (social cohesion, safety, problems, aesthetic quality and socioeconomic factors) derived from survey responses and census data. Adjusting for other neighborhood characteristics strengthened protective associations amongst Hispanics, but did not change the significant associations in African American men. These results demonstrate heterogeneity in the associations of race/ethnic composition with mental health and the need for further exploration of which aspects of neighborhood environments may contribute to these associations.

Drawing on a model of ethnic-racial socialization (E-RS; Pinderhughes, 2013), this study examined hypothesized relations among parents' role variables (family ethnic identity and acknowledgment of cultural and racial differences), cultural socialization (CS) behaviors, and children's self-perceptions (ethnic self-label and feelings about self-label). The sample comprised 44 U.S.-based parents and their daughters ages 6 to 9 who were adopted from China. Correlation analyses revealed that parents' role variables and CS behaviors were related, and children's ethnic self-label was related to family ethnic identity and CS behaviors. Qualitative analyses point to complexities in children's ethnic identity and between family and children's ethnic identities. Together, these findings provide support for the theoretical model and suggest that although ethnic identity among international transracial adoptees (ITRAs) has similarities to that of nonadopted ethnic minority children, their internal experiences are more complex. © 2015 Wiley Periodicals, Inc.

This 3-year prospective study aimed to identify baseline parameters that predicted the progression of carotid-femoral pulse wave velocity (cf-PWV), which was used to evaluate aortic stiffness, among Singapore's multi-ethnic Asians with type 2 diabetes (T2DM). The cf-PWV was measured by the gold-standard tonometry method in 994 T2DM subjects at baseline and follow-up. The annual rate of cf-PWV change was calculated, and individuals above the 90 th percentile with rate≥1.42 m/s per year were regarded as rapid progressors (n = 104). In a subgroup analysis of subjects with normal cf-PWV at 1 st visit (n = 611), incident aortic stiffness was defined as follow-up cf-PWV≥10 m/s (n = 188). The total cohort (mean age:57 ± 10 years; 53.4% Chinese, 20.4% Malay, 22.9% Indian, 3.2% 'Others') displayed a median annual cf-PWV progression rate of 0.2 m/s. Adjusted multivariate regression analyses showed that baseline age, cf-PWV and body mass index (BMI) constantly predicted follow-up cf-PWV, annual cf-PWV progression rate, rapid cf-PWV progression, and incident aortic stiffness. Paradoxically, lower baseline cf-PWV was associated with elevated annual cf-PWV progression rate and rapid progressors. This inverse relationship remained significant across ethnicities after ethnic stratification. Higher BMI independently predicted cf-PWV progression in Chinese and Indians, but not in Malay and 'Others' ethnic groups. Increased age was a significant predictor in Chinese and 'Others' ethnicities. We demonstrated that baseline BMI is a modifiable independent risk factor of cf-PWV progression and incident aortic stiffness. Therefore, better obesity management may impede aortic stiffness in Singapore's T2DM patients, especially in the Chinese and Indians. Copyright © 2017. Published by Elsevier B.V.

to determine differences in antenatal care use between the native population and different ethnic minority groups in the Netherlands. the Generation R Study is a multi-ethnic population-based prospective cohort study. seven midwife practices participating in the Generation R Study conducted in the city of Rotterdam. in total 2093 pregnant women with a Dutch, Moroccan, Turkish, Cape Verdean, Antillean, Surinamese-Creole and Surinamese-Hindustani background were included in this study. to assess adequate antenatal care use, we constructed an index, including two indicators; gestational age at first visit and total number of antenatal care visits. Logistic regression analysis was used to assess differences in adequate antenatal care use between different ethnic groups and a Dutch reference group, taking into account differences in maternal age, gravidity and parity. overall, the percentages of women making adequate use are higher in nulliparae than in multiparae, except in Dutch women where no differences are present. Except for the Surinamese-Hindustani, all women from ethnic minority groups make less adequate use as compared to the native Dutch women, especially because of late entry in antenatal care. When taking into account potential explanatory factors such as maternal age, gravidity and parity, differences remain significant, except for Cape-Verdian women. Dutch-Antillean, Moroccan and Surinamese-Creole women exhibit most inadequate use of antenatal care. this study shows that there are ethnic differences in the frequency of adequate use of antenatal care, which cannot be attributed to differences in maternal age, gravidity and parity. Future research is necessary to investigate whether these differences can be explained by socio-economic and cultural factors. clinicians should inform primiparous women, and especially those from ethnic minority groups, on the importance of timely antenatal care entry.

Risk of cardiovascular disease varies between ethnic groups and the aim of this study was to investigate differences in cardiovascular risk factors, and total cardiovascular risk between ethnic groups in Norway. Cross-sectional study using data from the Cohort of Norway (CONOR). A sample of 62,145 participants, 40-65 years of age, originating from 11 geographical regions, were included in our study. Self-reported variables, blood samples and physical measurements were used to estimate age- and time-adjusted mean values of cardiovascular risk factors for different ethnic groups. The 10-year risks of cardiovascular mortality and cardiovascular events were calculated using the Framingham and NORRISK risk models. We observed differences between ethnic groups for cardiovascular risk factors and both Framingham and NORRISK risk scores. NORRISK showed significant differences by ethnicity in women only. Immigrants from the Indian subcontinent had the lowest high-density lipoprotein (HDL) levels, the highest levels of blood glucose, triglycerides, total cholesterol/HDL ratio, waist hip ratio and diabetes prevalence. Immigrants from the former Yugoslavia had the highest Framingham scores, high blood pressure, high total cholesterol/HDL ratio, overweight measures and smoking. Low cardiovascular risk was observed among East Asian immigrants. The previously reported excess cardiovascular risk among immigrants from the Indian subcontinent was supported in this study. We also showed that immigrants from the former Yugoslavian countries had a higher total 10-year risk of cardiovascular events than other ethnic groups. This study adds information about ethnic groups in Norway which needs to be addressed in further research and targeted prevention strategies.

Background Previous research suggests neighborhood-level racial/ethnic residential segregation is linked to health, but it has not been studied prospectively in relation to cardiovascular disease (CVD). Methods and Results Participants were 1,595 non-Hispanic Black, 2,345 non-Hispanic White, and 1,289 Hispanic adults from the Multi-Ethnic Study of Atherosclerosis free of CVD at baseline (ages 45-84). Own-group racial/ethnic residential segregation was assessed using the Gi∗ statistic, a measure of how the neighborhood racial/ethnic composition deviates from surrounding counties’ racial/ethnic composition. Multivariable Cox proportional hazards modeling was used to estimate hazard ratios (HR) for incident CVD (first definite angina, probable angina followed by revascularization, myocardial infarction, resuscitated cardiac arrest, CHD death, stroke, or stroke death) over 10.2 median years of follow-up. Among Blacks, each standard deviation increase in Black segregation was associated with a 12% higher hazard of developing CVD after adjusting for demographics (95% Confidence Interval (CI): 1.02, 1.22). This association persisted after adjustment for neighborhood-level characteristics, individual socioeconomic position, and CVD risk factors (HR: 1.12; 95% CI: 1.02, 1.23). For Whites, higher White segregation was associated with lower CVD risk after adjusting for demographics (HR: 0.88; 95% CI: 0.81, 0.96), but not after further adjustment for neighborhood characteristics. Segregation was not associated with CVD risk among Hispanics. Similar results were obtained after adjusting for time-varying segregation and covariates. Conclusions The association of residential segregation with cardiovascular risk varies according to race/ethnicity. Further work is needed to better characterize the individual- and neighborhood-level pathways linking segregation to CVD risk. PMID:25447044

A large electronic database of histopathology reports was used to study the ethnic distribution of microscopic colitis in the United States. Miraca Life Sciences is a nation-wide pathology laboratory that receives biopsy specimens submitted by 1500 gastroenterologists distributed throughout the United States. In a case-control study, the prevalence of microscopic colitis in 4 ethnic groups (East Asians, Indians, Hispanics, and Jews) was compared with that of all other ethnic groups (composed of American Caucasians and African Americans), serving as reference group. A total of 11,706 patients with microscopic colitis were included in the analysis. In all ethnic groups alike, microscopic colitis was more common in women than men (78% versus 22%, odds ratio = 3.40, 95% confidence interval = 3.26-3.55). In all ethnic groups, the prevalence of microscopic colitis showed a continuous age-dependent rise. Hispanic patients with microscopic colitis were on average younger than the reference group (59.4 ± 16.2 years versus 64.2 ± 13.8 years, P < 0.001). Jewish patients with microscopic colitis were slightly older than the reference group (65.6 ± 13.4 years, P = 0.015). Compared with the reference group (prevalence = 1.20%), microscopic colitis was significantly less common among patients of Indian (prevalence = 0.28%, odds ratio = 0.32, 95% confidence interval = 0.13-0.65), East Asian (0.22%, 0.19, 0.14-0.26), or Hispanic decent (0.48%, 0.40, 0.36-0.45) and significantly more common among Jewish patients (1.30%, 1.10, 1.01-1.21). Microscopic colitis shows striking variations of its occurrence among different ethnic groups. Such variations could point at differences in the exposure to environmental risk factors.

Diabetes susceptibility in ethnic minority groups from Turkey, Vietnam, Sri Lanka and Pakistan compared with Norwegians - the association with adiposity is strongest for ethnic minority women

PubMed Central

2012-01-01

Background The difference in diabetes susceptibility by ethnic background is poorly understood. The aim of this study was to assess the association between adiposity and diabetes in four ethnic minority groups compared with Norwegians, and take into account confounding by socioeconomic position. Methods Data from questionnaires, physical examinations and serum samples were analysed for 30-to 60-year-olds from population-based cross-sectional surveys of Norwegians and four immigrant groups, comprising 4110 subjects born in Norway (n = 1871), Turkey (n = 387), Vietnam (n = 553), Sri Lanka (n = 879) and Pakistan (n = 420). Known and screening-detected diabetes cases were identified. The adiposity measures BMI, waist circumference and waist-hip ratio (WHR) were categorized into levels of adiposity. Gender-specific logistic regression models were applied to estimate the risk of diabetes for the ethnic minority groups adjusted for adiposity and income-generating work, years of education and body height used as a proxy for childhood socioeconomic position. Results The age standardized diabetes prevalence differed significantly between the ethnic groups (women/men): Pakistan: 26.4% (95% CI 20.1-32.7)/20.0% (14.9-25.2); Sri Lanka: 22.5% (18.1-26.9)/20.7% (17.3-24.2), Turkey: 11.9% (7.2-16.7)/12.0% (7.6-16.4), Vietnam: 8.1% (5.1-11.2)/10.4% (6.6-14.1) and Norway: 2.7% (1.8-3.7)/6.4% (4.6-8.1). The prevalence increased more in the minority groups than in Norwegians with increasing levels of BMI, WHR and waist circumference, and most for women. Highly significant ethnic differences in the age-standardized prevalence of diabetes were found for both genders in all categories of all adiposity measures (p < 0.001). The Odds Ratio (OR) for diabetes adjusted for age, WHR, body height, education and income-generating work with Norwegians as reference was 2.9 (1.30-6.36) for Turkish, 2.7 (1.29-5.76) for Vietnamese, 8.0 (4.19-15.14) for Sri Lankan and 8.3 (4.37-15.58) for Pakistani

Millennials (ages 18-35) are now the largest living generation in the US, making it important to understand and characterize the rising trend of colorectal cancer incidence in this population, as well as other younger generations of Americans. Data from the New Jersey State Cancer Registry (n = 181 909) and Surveillance, Epidemiology, and End Results program (n = 448 714) were used to analyze invasive CRC incidence trends from 1979 to 2014. Age, sex, race, ethnicity, subsite, and stage differences between younger adults (20-49) and screening age adults (≥50) in New Jersey (NJ) were examined using chi-square; and, we compared secular trends in NJ to the United States (US). Whites, men, and the youngest adults (ages 20-39) are experiencing greater APCs in rectal cancer incidence. Rates among younger black adults, overall, were consistently higher in both NJ and the US over time. When compared to older adults, younger adults with CRC in NJ were more likely to be: diagnosed at the late stage, diagnosed with rectal cancer, male, non-white, and Hispanic. Invasive CRC incidence trends among younger adults were found to vary by age, sex, race, ethnicity, and subsite. Large, case-level, studies are needed to understand the role of genetics, human papillomavirus (HPV), and cultural and behavioral factors in the rise of CRC among younger adults. Provider and public education about CRC risk factors will also be important for preventing and reversing the increasing CRC trend in younger adults. © 2018 The Authors.

Objective To describe the occurrence of Kawasaki syndrome (KS) among different racial/ethnic groups in Hawai‘i. Methods Retrospective analysis of children <18 years of age, with a focus on children <5 years of age, living in Hawai‘i who were hospitalized with KS using the 1996–2006 Hawai‘i State Inpatient Data. Results Children <5 years of age accounted for 84% of the 528 patients <18 years of age with KS. The average annual incidence among this age group was 50.4 per 100,000 children <5 years of age, ranging from 45.5 to 56.5. Asian and Pacific Islander children accounted for 92% of the children <5 years of age with KS during the study period; the average annual incidence was 62.9 per 100,000. Within this group, Japanese children had the highest incidence (210.5), followed by Native Hawaiian children (86.9), other Asian children (84.9), and Chinese children (83.2). The incidence for white children (13.7) was lower than for these racial/ethnic groups. The median age of KS admission for children <5 years of age was 21 months overall, 24 months for Japanese children, 14.5 months for Native Hawaiian children and 26.5 months for white children. Conclusions The high average annual KS incidence for children <5 years of age in Hawai‘i compared to the rest of the United States population reflects an increased KS incidence among Asian and Pacific Islander children, especially Japanese children. The incidence for white children was slightly higher than or similar to that generally reported nationwide. PMID:20845285

Comparison of dental maturity in children of different ethnic origins: international maturity curves for clinicians.

2005-09-01

Dental maturity was studied with 9577 dental panoramic tomograms of healthy subjects from 8 countries, aged between 2 and 25 years of age. Demirjian's method based on 7 teeth was used for determining dental maturity scores, establishing gender-specific tables of maturity scores and development graphs. The aim of this study was to give dental maturity standards when the ethnic origin is unknown and to compare the efficiency and applicability of this method to forensic sciences and dental clinicians. The second aim was to compare the dental maturity of these different populations. We noted an high efficiency for International Demirjian's method at 99% CI (0.85% of misclassified and a mean accuracy between 2 to 18 years +/- 2.15 years), which makes it useful for forensic purposes. Nevertheless, this international method is less accurate than Demirjian's method developed for a specific country, because of the inter-ethnic variability obtained by the addition of 8 countries in the dental database. There are inter-ethnic differences classified in three major groups. Australians have the fastest dental maturation and Koreans have the slowest.

The burden of breast cancer in Asia is escalating. We evaluated the impact of ethnicity on survival after breast cancer in the multi-ethnic region of South East Asia. Using the Singapore-Malaysia hospital-based breast cancer registry, we analyzed the association between ethnicity and mortality following breast cancer in 5,264 patients diagnosed between 1990 and 2007 (Chinese: 71.6%, Malay: 18.4%, Indian: 10.0%). We compared survival rates between ethnic groups and calculated adjusted hazard ratios (HR) to estimate the independent effect of ethnicity on survival. Malays (n = 968) presented at a significantly younger age, with larger tumors, and at later stages than the Chinese and Indians. Malays were also more likely to have axillary lymph node metastasis at similar tumor sizes and to have hormone receptor negative and poorly differentiated tumors. Five year overall survival was highest in the Chinese women (75.8%; 95%CI: 74.4%-77.3%) followed by Indians (68.0%; 95%CI: 63.8%-72.2%), and Malays (58.5%; 95%CI: 55.2%-61.7%). Compared to the Chinese, Malay ethnicity was associated with significantly higher risk of all-cause mortality (HR: 1.34; 95%CI: 1.19-1.51), independent of age, stage, tumor characteristics and treatment. Indian ethnicity was not significantly associated with risk of mortality after breast cancer compared to the Chinese (HR: 1.14; 95%CI: 0.98-1.34). In South East Asia, Malay ethnicity is independently associated with poorer survival after breast cancer. Research into underlying reasons, potentially including variations in tumor biology, psychosocial factors, treatment responsiveness and lifestyle after diagnosis, is warranted.

Diabetes is increasing worldwide, and information on risk factors to develop targeted interventions is limited. Therefore, we analyzed data of the Suriname Health Study to estimate the prevalence of prediabetes and diabetes. We also explored whether ethnic differences in prediabetes or diabetes risk could be explained by biological, demographic, lifestyle, anthropometric, and metabolic risk factors. The study was designed according to the WHO Steps guidelines. Fasting blood glucose levels were measured in 3393 respondents, aged 15-65 years, from an Amerindian, Creole, Hindustani, Javanese, Maroon or Mixed ethnic background. Prediabetes was defined by fasting blood glucose levels between 6.1 and 7.0 mmol/L and diabetes by fasting blood glucose levels ≥7.0 mmol/L or 'self-reported diabetes medication use.' For all ethnicities, we analyzed sex, age, marital status, educational level, income status, employment, smoking status, residence, physical activity, body mass index, waist circumference, hypertension, and the levels of triglyceride, total cholesterol, high-density lipoprotein-cholesterol and low-density lipoprotein-cholesterol. The prevalence of prediabetes was 7.4%, while that of diabetes was 13 0%. From these diabetes cases, 39.6% were not diagnosed previously. No ethnic differences were observed in the prevalence of prediabetes. For diabetes, Hindustanis (23.3%) had twice the prevalence compared to other ethnic groups (4.7-14.2%). The associations of the risk factors with prediabetes or diabetes varied among the ethnic groups. The differences in the associations of ethnic groups with prediabetes or diabetes were partly explained by these risk factors. The prevalence of diabetes in Suriname is high and most elevated in Hindustanis. The observed variations in risk factors among ethnic groups might explain the ethnic differences between these groups, but follow-up studies are needed to explore this in more depth.

NHS Direct, a leading telephone healthcare provider worldwide, provided 24/7 health care advice and information to the public in England and Wales (1998-2014). The fundamental aim of this service was to increase accessibility, however, research has suggested a disparity in the utilisation of this service related to ethnicity. This research presents the first national study to determine how the diverse population in England have engaged with this service. NHS Direct call data from the combined months of July, 2010 October, 2010, January 2011 and April, 2011 was analysed (N = 1,342, 245) for all 0845 4647 NHS Direct core service calls in England. Expected usage of NHS Direct was determined for each ethnic group of the population by age and gender and compared by actual usage using Chi-square analysis. A one-way analysis of variance (ANOVA) was used to determine variations of uptake by ethnic group and Index for Multiple Deprivation (IMD) 2010 rank. Results confirmed that all mixed ethnic groups (White and Black Caribbean, White and Black African, White and Asian) had a higher than expected uptake of NHS Direct which held consistent across all age groups. Lower than expected uptake was found for Black (African/Caribbean) and Asian (Bangladeshi/Indian/Chinese) ethnic group which held consistent by age and gender. For the Pakistani ethnic group usage was higher than expected in adults aged 40 years and older although was lower than expected in younger age groups (0-39). Findings support previous research suggesting a variation in usage of NHS Direct influenced by ethnicity, which is evidenced on a national level. Further research is now required to examine the underlying barriers that contribute to the ethnic variation in uptake of this service.

To date, there is no consensus regarding adult cutoffs of percentage of body fat or estimated cutoffs on the basis of nationally representative samples with rigorous body-composition measurements. We developed cutoffs of percentage of body fat on the basis of the relation between dual-energy x-ray absorptiometry-measured fat mass and BMI (in kg/m(2)) stratified by sex, age, and race-ethnicity by using 1999-2004 NHANES data. A simple regression (percentage of body fat = β(0) + β(1) × 1 ÷ BMI) was fit for each combination of sex (men and women), 3 age groups (18-29, 30-49, and 50-84 y of age), and 3 race-ethnicity groups (non-Hispanic whites, non-Hispanic blacks, and Mexican Americans). Model fitting included a consideration of complex survey design and multiple imputations. Cutoffs of percentage of body fat were computed that corresponded to BMI cutoffs of 18.5, 25, 30, 35, and 40 on the basis of estimated prediction equations. R(2) ranged from 0.54 to 0.72 for men (n = 6544) and 0.58 to 0.79 for women (n = 6362). In men, the percentage of body fat that corresponded to a BMI of 18.5, 25, 30, 35, and 40 across age and racial-ethnic groups ranged from 12.2% to 19.0%, 22.6% to 28.0%, 27.5% to 32.3%, 31.0% to 35.3%, and 33.6% to 37.6%, respectively; the corresponding ranges in women were from 24.6% to 32.3%, 35.0% to 40.2%, 39.9% to 44.1%, 43.4% to 47.1%, and 46.1% to 49.4%, respectively. The oldest age group had the highest cutoffs of percentage of body fat. Non-Hispanic blacks had the lowest cutoffs of percentage of body fat. Cutoffs of percentage of body fat were higher in women than in men. Cutoffs of percentage of body fat that correspond to the current US BMI cutoffs are a function of sex, age, and race-ethnicity. These factors should be taken into account when considering the appropriateness of levels of percentage of body fat.

Internationally, ethnic inequalities in mortality within countries are increasingly recognized as a public health concern. But few countries have data to monitor such inequalities. We aimed to provide a detailed description of ethnic inequalities (Māori [indigenous], Pacific, and European/Other) in mortality for a country with high quality ethnicity data, using both standard and novel visualization methods. Cohort studies of the entire New Zealand population were conducted, using probabilistically-linked Census and mortality data from 1981 to 2011 (68.9 million person years). Absolute (standardized rate difference) and relative (standardized rate ratio) inequalities were calculated, in 1-74-year-olds, for Māori and Pacific peoples in comparison to European/Other. All-cause mortality rates were highest for Māori, followed by Pacific peoples then European/Other, and declined in all three ethnic groups over time. Pacific peoples experienced the slowest annual percentage fall in mortality rates, then Māori, with European/Other having the highest percentage falls - resulting in widening relative inequalities. Absolute inequalities, however, for both Māori and Pacific males compared to European/Other have been falling since 1996. But for females, only Māori absolute inequalities (compared with European/Other) have been falling. Regarding cause of death, cancer is becoming a more important contributor than cardiovascular disease (CVD) to absolute inequalities, especially for Māori females. We found declines in all-cause mortality rates, over time, for each ethnic group of interest. Ethnic mortality inequalities are generally stable or even falling in absolute terms, but have increased on a relative scale. The drivers of these inequalities in mortality are transitioning over time, away from CVD to cancer and diabetes; such transitions are likely in other countries, and warrant further research. To address these inequalities, policymakers need to enhance prevention

Schizophrenia is a disabling clinical syndrome found across the world. While the incidence and clinical expression of this illness are strongly influenced by ethnic factors, it is unclear whether patients from different ethnicities show distinct brain deficits. In this multicentre study, we used structural Magnetic Resonance Imaging to investigate neuroanatomy in 126 patients with first episode schizophrenia who came from 4 ethnically distinct cohorts (White Caucasians, African-Caribbeans, Japanese, and Chinese). Each patient was individually matched with a healthy control of the same ethnicity, gender, and age (±1 year). We report a reduction in the gray matter volume of the right anterior insula in patients relative to controls (P < .05 corrected); this reduction was detected in all 4 ethnic groups despite differences in psychopathology, exposure to antipsychotic medication and image acquisition sequence. This finding provides evidence for a neuroanatomical signature of schizophrenia expressed above and beyond ethnic variations in incidence and clinical expression. In light of the existing literature, implicating the right anterior insula in bipolar disorder, depression, addiction, obsessive-compulsive disorder, and anxiety, we speculate that the neuroanatomical deficit reported here may represent a transdiagnostic feature of Axis I disorders. © The Author 2015.

Disparities in infertility and access to infertility treatments, such as assisted reproductive technology (ART), by race/ethnicity, have been reported. However, identifying disparities in ART usage may have been hampered by missing race/ethnicity information in ART surveillance. We review infertility prevalence and treatment disparities, use recent data to examine ART use in the United States by race/ethnicity and residency in states with mandated insurance coverage for in vitro fertilization (IVF), and discuss approaches for reducing disparities. We used 2014 National ART Surveillance System (NASS) data to calculate rates of ART procedures per million women 15-44 years of age, a proxy measure of ART utilization, for Census-defined racial/ethnic groups in the United States; rates were further stratified by the presence of insurance mandates for IVF treatment. Missing race/ethnicity data (35.6% of cycles) were imputed. Asian/Pacific Islander (A/PI) women had the highest rates of ART utilization at 5883 ART procedures per million women 15-44 years of age in 2014, whereas American Indian/Alaska Native non-Hispanic women had the lowest rates at 807 per million, compared with other racial/ethnic groups. In each racial/ethnic category, ART utilization rates were higher for women in states with an insurance mandate for IVF treatment versus those without. In 2014, A/PI women had the highest rates of ART utilization. ART utilization for all racial/ethnic groups was higher in states with insurance mandates for IVF than those without, although disparities were still evident. Although mandates may increase access to infertility treatments, they are not sufficient to eliminate these disparities.

The current study examined whether Anglo culture orientation modified the association between adolescents’ perceived ethnic discrimination and ethnic identity affirmation over time in a sample of Mexican-origin adolescent mothers (N = 205, M age = 16.24 years). Results indicated that perceived ethnic discrimination was significantly associated with decreases in ethnic identity affirmation over time for adolescents reporting high Anglo culture orientation, but no relation existed for adolescents reporting low Anglo culture orientation. Findings suggest that a person-environment mismatch (i.e., between adolescents’ perceptions of their connection to Anglo culture and the messages they receive from others regarding that connection in terms of perceived ethnic discrimination) may be detrimental to adolescents’ development of positive feelings about their ethnicity.

This study investigates the emergence, development and structure of ethnic identity during childhood. Forty Roma children living in Greece aged between 2.8 and 11.9 years answered questions about their awareness/recognition of four aspects of their ethnic identity-namely place of habitation, traditional costumes, the Roma language, and early betrothal of children-their identity and their sense of stability and constancy. The study also investigates how the children feel about the abandonment of those four aspects. The evidence from the current data supports the hypothesis that awareness of ethnic identity emerges before the age of 4. Moreover, this study offers direct empirical evidence of the multidimensionality of ethnic identity. A model of three concentric rings is proposed, extending from a core containing the most highly valued aspects of ethnic identity to the outer annulus that comprises the nonpermanent and nonstable aspects of ethnic identity. The aspects in each annulus differ in terms of the development of the sense of stability and constancy and the feelings associated with loss of the aspects in question. Even the youngest participants considered the aspects in the core to be stable and constant as well as emotionally charged; and even the 11-year-olds did not consider the aspects contained in the outer, more fluid annulus as stable and constant aspects of their ethnic identity. The development of an aspect is determined by what the majority of adults in a society, at a particular time in history, consider to be most important.
