Objective California children’s exposures to polybrominated diphenyl ether flame retardants (PBDEs) are among the highest measured worldwide. We previously reported associations for prenatal and childhood PBDE exposures with decrements in attention, processing speed, fine motor coordination, and cognition in children at ages 5 and 7 years. Here, we investigate associations of PBDEs with attention and executive function at ages 9 to 12 years in the expanded CHAMACOS cohort. Methods We measured PBDEs in prenatal and child age 9 year serum samples for families enrolled in the study since pregnancy (“CHAM1”, N=321). In a subsequent cohort for which families were enrolled at child age 9 (“CHAM2”, N=301), we measured PBDEs in maternal and child samples collected at child age 9, and used predictive modeling to estimate prenatal exposure levels. We examined associations of measured and estimated PBDE concentrations on children’s attention and executive functioning at ages 9, 10½, and 12 years. Results Geometric means for prenatal and childhood ΣPBDE levels (sum of PBDE−47,−99,−100,−153) for the expanded CHAMACOS cohort were 26.3 and 63.2 ng/g lipid, respectively, and did not differ significantly between CHAM1 and CHAM2 families. We found consistent associations of prenatal exposure to PBDEs with poorer attention and executive function, measured with parent report and direct neuropsychological testing of the child. For example, using GEE models of repeated outcome measures at age 9 and 12, a 10-fold increase in prenatal ΣPBDE was associated with poorer response consistency on the Conners’ Continuous Performance Test II (β=2.9; 95% CI: 0.9, 4.8) and poorer working memory on the Behavioral Rating Inventory of Executive Function (β=2.5; 95% CI: 0.5, 4.4). Child age 9 ΣPBDE levels were associated with poorer parent-reported attention and executive function for girls but not boys. Conclusions Our results suggest that the prefrontal cortex may be a

Background. Children <2 years of age are at high risk of influenza-related mortality and morbidity. However, the appropriate dose of oseltamivir for children <2 years of age is unknown. Methods. The National Institute of Allergy and Infectious Diseases Collaborative Antiviral Study Group evaluated oseltamivir in infants aged <2 years in an age–de-escalation, adaptive design with a targeted systemic exposure. Results. From 2006 to 2010, 87 subjects enrolled. An oseltamivir dose of 3.0 mg/kg produced drug exposures within the target range in subjects 0–8 months of age, although there was a greater degree of variability in infants <3 months of age. In subjects 9–11 months of age, a dose of 3.5 mg/kg produced drug exposures within the target range. Six of 10 subjects aged 12–23 months receiving the Food and Drug Administration–approved unit dose for this age group (ie, 30 mg) had oseltamivir carboxylate exposures below the target range. Virus from 3 subjects developed oseltamivir resistance during antiviral treatment. Conclusions. The appropriate twice-daily oral oseltamivir dose for infants ≤8 months of age is 3.0 mg/kg, while the dose for infants 9–11 months old is 3.5 mg/kg.

Blood polyunsaturated fatty acids (PUFA) are involved in allergy development, but the etiological role of n-6 and n-3 PUFA is still controversial. A European multicenter study of children (IDEFICS) provided the opportunity to explore the cross-sectional association between fatty acids (FA) and allergy. Blood FA levels were measured in 2600 children aged 2-9 years and were recorded as the percentage of weight of all FA detected. Logistic regression of allergy status on FA components was adjusted for age, sex, country, body mass index, family history of allergic disease, breast-feeding, and number of siblings. The results were given as odds ratios (OR) for current vs no allergy ever and an increase in FA by 1 s.d. Overall, higher proportions of n-6 PUFA were associated with higher odds of allergy (OR=1.21 (1.05, 1.40)). Monounsaturated FA (MUFA) were associated with reduced risk for allergy (OR=0.75 (0.65, 0.87)), whereas saturated FA did not differ by allergy status. The strongest associations were observed in children <4 years old, with ORs of allergy given as 1.62 (1.15, 2.29) for n-3 PUFA and 0.63 (0.42, 0.95) for MUFA. With regard to individual FA, these associations were independently observed for docosapentaenoic acid (22:5 n-3) and oleic acid (18:1 n-9). Both PUFA subtypes were positively associated with allergy in an age-dependent manner, whereas MUFA was associated with less allergy. The observation of high proportions of n-3 PUFA in allergic children younger than 4 years might help to understand the nature of early onset of atopic disease.

We examined trends of physical activity and screen time among nationally representative samples of children aged 9-13 years to explore whether children overall are becoming less physically active and less likely to be in compliance with screen time recommendations. We analyzed Youth Media Campaign Longitudinal Survey data for trends and demographic patterns of free time and organized physical activity, and hours and minutes of watching television and playing video or computer games. Child-parent dyads for 2002 (N = 3114), 2004 (N = 5177), and 2006 (N = 1200) were analyzed. On the day before the interview, and for free time physical activity in the past week, children reported a significant increase in physical activity from 2002-2006. Screen time levels were stable overall; 76.4% of children met the recommendations of 2 hours or less of daily screen time. Levels of physical activity among U.S. children aged 9-13 years were stable, or levels slightly improved from 2002-2006. Except for some subgroup differences, trends for compliance with screen time recommendations were also stable from 2002-2006 for U.S. children aged 9-13 years.

Background: Regular milk consumption during childhood and adolescence is recommended for bone health. However, milk consumption increases circulating insulin-like growth factor I concentrations, and may also accelerate puberty. Objective: We prospectively investigated the association between milk consumption and age at menarche in the Growing Up Today Study. Methods: Study participants were 5583 US girls who were premenarcheal and ages 9–14 y in 1996. Girls were followed through 2001, at which time 97% of noncensored participants had reported menarche. Frequency of milk and meat consumption was calculated with the use of annual youth/adolescent food frequency questionnaires from 1996–1998. Intake of related nutrients was also measured. Age at menarche was self-reported annually through 2001. Results: During follow-up, 5227 girls attained menarche over 10,555 accrued person-years. In models adjusted for dietary and sociodemographic predictors of menarche, frequency of milk consumption did not predict age at onset of menarche (for >3 glasses of milk/d vs. 1.1–4 glasses/wk, HR: 0.93; 95% CI: 0.83, 1.04). After additional adjustment for body size, premenarcheal girls consuming >3 glasses of milk daily were 13% less likely (95% CI: −3%, −23%; P-trend: <0.01) to attain menarche in the next month relative to those consuming 1.1–4 glasses/wk. Neither total meat nor red meat consumption was associated with age at menarche. Conclusions: Our findings suggest that regular consumption of milk in girls aged ≥9 y is unlikely to substantially affect age at onset of menarche. Studies assessing associations between diet in early childhood and pubertal timing may be more illuminating. PMID:26136590

Immunogenicity and safety of the human papillomavirus (HPV)-16/18 AS04-adjuvanted vaccine were evaluated in healthy Chinese females aged 9-45 years in 2 phase IIIB, randomized, controlled trials. Girls aged 9-17 years (ClinicalTrials.gov, NCT00996125) received vaccine (n = 374) or control (n = 376) and women aged 26-45 years (NCT01277042) received vaccine (n = 606) or control (n = 606) at months 0, 1, and 6. The primary objective was to show non-inferiority of anti-HPV-16 and -18 immune responses in initially seronegative subjects at month 7, compared with Chinese women aged 18-25 years enrolled in a separate phase II/III trial (NCT00779766). Secondary objectives were to describe the anti-HPV-16 and -18 immune response, reactogenicity and safety. At month 7, immune responses were non-inferior for girls (9-17 years) vs. young women (18-25 years): the upper limit of the 95% confidence interval (CI) for the geometric mean titer (GMT) ratio (women/girls) was below the limit of 2 for both anti-HPV-16 (0.37 [95% CI: 0.32, 0.43]) and anti-HPV-18 (0.42 [0.36, 0.49]). Immune responses at month 7 were also non-inferior for 26-45 year-old women vs. 18-25 year-old women: the upper limit of the 95% CI for the difference in seroconversion (18-25 minus 26-45) was below the limit of 5% for both anti-HPV-16 (0.00% [-1.53, 1.10]) and anti-HPV-18 (0.21% [-1.36, 1.68]). GMTs were 2- to 3-fold higher in girls (9-17 years) as compared with young women (18-25 years). The HPV-16/18 AS04-adjuvanted vaccine had an acceptable safety profile when administered to healthy Chinese females aged 9-45 years.

We conducted three experiments to study the role of instrumental (e.g. knife-bread) and categorical (e.g. cake-bread) relations in the development of conceptual organization with a priming paradigm, by varying the nature of the task (naming--Experiment 1--or categorical decision--Experiments 2 and 3). The participants were 5-, 7- and 9-year-old children and adults. The results showed that on both types of task, adults and 9-year-old children presented instrumental and categorical priming effects, whereas 5-year-old children presented mainly instrumental priming effects, with categorical effects remaining marginal. Moreover, the magnitude of the instrumental priming effects decreased with age. Finally, the priming effects observed for 7-year-old children depended on the task, especially for the categorical effects. The theoretical implications of these results for our understanding of conceptual reorganization from 5 to 9 years of age are discussed.

Here we report the first evaluation of T-cell responses upon a second acellular pertussis booster vaccination in Dutch children at 9 years of age, 5 years after a preschool booster vaccination. Blood samples of children 9 years of age were studied longitudinally until 1 year after the second aP booster and compared with those after the first aP booster in children 4 and 6 years of age from a cross-sectional study. After stimulation with pertussis-vaccine antigens, Th1, Th2 and Th17 cytokine responses were measured and effector memory cells (CCR7-CD45RA-) were characterized by 8-colour FACS analysis. The second aP booster vaccination at pre-adolescent age in wP primed individuals did increase pertussis-specific Th1 and Th2 cytokine responses. Noticeably, almost all T-cell responses had increased with age and were already high before the booster vaccination at 9 years of age. The enhancement of T-cell immunity during the 5 year following the booster at 4 years of age is probably caused by natural boosting due to the a high circulation of pertussis. However, the incidence of pertussis is high in adolescents and adults who have only received the Dutch wP vaccine during infancy and no booster at 4 years of age. Therefore, an aP booster vaccination at adolescence or later in these populations might improve long-term immunity against pertussis and reduce the transmission to the vulnerable newborns.

OBJECTIVE: To determine the prevalence of vitamin A deficiency in children aged 6-9 years in northern Ethiopia. METHODS: A cross-sectional study was carried out and the data were analysed for 824 (61.5%) of 1339 eligible children for whom there was complete information on biochemical vitamin A status, dietary vitamin A intake, ocular examination for xerophthalmia, and anthropometry. FINDINGS: The prevalence of xerophthalmia was 5.8%; serum retinol levels were below 0.35 mumol/l and between 0.35 and 0.70 mumol/l in 8.4% and 51.1% of the children respectively. The liver vitamin A reserve (modified relative dose response ratio > or = 0.06) was low in 41.0% of the children. CONCLUSION: The high prevalence of severe vitamin A deficiency in children aged 6-9 years indicates the need to reevaluate the practice of targeting vitamin A supplementation programmes on children under 6 years of age in areas where vitamin A deficiency is endemic.

Background. Given the high infant measles mortality rate, there is interest in whether a measles immunization regimen beginning at <12 months of age provides lasting immunity. Methods. Measles-specific immune responses were evaluated in 70 children aged 5–10 years after primary measles vaccine administered at 6, 9, or 12 months. Results. At 5–10 years of age, the stimulation index for measles T-cell proliferation was 11.4 (SE, 1.3), 10.9 (SE, 1.5), and 14.4 (SE 2.1) when the first measles dose was given at 6, 9, or 12 months, respectively. Neutralizing antibody concentration (geometric mean titer [GMT]) in those immunized at 6 months of age was 125 mIU/mL (95% confidence interval [CI], 42–377) in the presence of passive antibodies (PAs) and 335 mIU/mL (95% CI, 211–531) in those without PAs; in those immunized at 9 months, GMTs were 186 mIU/mL (95% CI, 103–335) and 1080 mIU/mL (95% CI, 642–1827) in the presence and absence of PAs, respectively. The GMT was 707 mIU/mL (95% CI, 456–1095) when vaccine was administered at 12 months (P ≤ .04). Conclusions. Measles-specific T-cell responses were sustained at 5–10 years of age regardless of age at time of primary measles immunization. Neutralizing antibody concentrations were lower in cohorts given the first vaccine dose at 6 months of age and in the presence of PAs; however, responses could be boosted by subsequent doses. Starting measles vaccination at <12 months of age may be beneficial during measles outbreaks or in endemic areas. PMID:23300162

U.S. estimates of seasonal influenza (flu) vaccine uptake in 2014-2015 were 62% for 5-12year olds, dropping to 47% for 13-17year olds. The Healthy People 2020 goal for these age groups is 80%. It is important to understand factors associated with influenza vaccination, especially for those ages where rates begin to decline. The objective of this study was to identify factors associated with influenza vaccination acceptance in 9-13year old children. An online U.S. survey of mothers of children aged 9-13 assessed children's influenza vaccine uptake in the previous season, healthcare utilization, sociodemographics, and vaccine attitudes. Multivariable logistic regression identified independent predictors of influenza vaccine status. There were 2363 respondents (Mean age=38years old). Referent children were 57% female and 66% non-minority race/ethnicity with a mean age of 10.6years. By maternal report, 59% of children had received an influenza vaccine in the previous season. Predictors of influenza vaccine uptake included a recommendation or strong recommendation from a health care provider, seeing a health care provider in the past year, positive attitudes regarding the influenza vaccine, and being a minority race. Child gender, age, insurance coverage, and whether the child had a regular healthcare provider were not associated with influenza vaccine uptake (p=n.s.). This sample reported overall rates of influenza vaccine uptake similar to national surveillance data, but still lower than national goals. Provider recommendations along with health attitudes and seeing a health care provider were associated with vaccine uptake. Promising interventions may include more directive physician messaging for influenza vaccine uptake in youth, encouraging more regular well-child visits during the adolescent years, and promoting influenza vaccination at alternative sites.

This study was to investigate parental acceptability of HPV vaccination for their sons and daughters aged 9-13 years under different cost scenarios, and factors associated with parental acceptability at market price. Participants were: (1) Chinese speaking parents aged 18-60 years with a Hong Kong ID card; (2) had a son or a daughter aged 9-13 years at the date of the survey; (3) the child had the right to abode in Hong Kong. Random telephone numbers were selected from up-to-date telephone directories of Hong Kong. A total of 300 eligible parents (boys' parents: 162; girls' parents: 138, response rate: 68.9% & 69%) provided verbal informed consent and completed the anonymous telephone interview during March to October 2016. Using parental acceptability of HPV vaccination at market price as the dependent variable, univariate and multiple logistic regression models were fitted. The prevalence of HPV vaccination was very low among boys and girls (0.6% vs. 2.2%, p = 0.242). Among those whose children had not taken up HPV vaccination, the prevalence of parental acceptability of HPV vaccination for the index son and daughter were: 14.9% and 27.4% (market price), and 51.6% and 63.0% (free vaccination). Adjusted for sociodemographic variables, attitudinal variables based on the Health Belief Model were associated with parental acceptability of HPV vaccination for their sons (perception that it was not worthy, perceived cue to action from mass media and perceived self-efficacy) and for their daughters (perceived susceptibility and perceived severity of HPV infection among females, perceived benefit of HPV vaccination and perceived self-efficacy). Coverage of HPV vaccination among children aged 9-13 years was very low. Instead of waiting for the free universal vaccination to become available, promotion of self-paid HPV vaccination targeting parents is urgently needed. Different strategies should be applied to boys' and girls' parents. Copyright © 2018 Elsevier

The prevalence of neurological disorders in resource-poor settings, although likely to be high, is largely unexplored. The prevalence and risk factors for neurological disorders, including epilepsy and intellectual, motor, vision, and hearing deficits, in children aged 9 to 15 years in the community were investigated. A new instrument was developed, validated, and used in a 2-stage community survey for neurological disorders in Lucknow, India. Screen-positives and random proportion of screen-negatives were validated using predefined criteria. Prevalence of different neurological disorders was calculated by weighted proportions. Of 6431 children screened, 221 were positive. A total of 214 screen-positives and 251 screen-negatives were validated. Prevalence of neurological disorders was 31.3 per 1000 children of this age group (weighted 95% confidence interval = 16.5, 46.4). The final model for risk factors included age, mud house, delayed cry at birth, and previous head injury. The prevalence of neurological disorders is high in this region. Predictors of neurological disorders are largely modifiable. © The Author(s) 2015.

The lower limbs of children aged 3-9 years present varying knock-knee deformities that have a direct impact on the diversification of the load-bearing axis of the valgus limb and on the modification of gait kinematics. The purpose of our study was to establish the reference values of knee alignment in a Greek population and whether this is linked to a change in the physical activity of children depending on the severity of the genu valgum. Using a clinical method, we measured both the tibiofemoral (TF) angle and the intermalleolar (IM) distance of the lower extremities of normal children. Subsequently, forms of the Netherlands Physical Activity Questionnaire (NPAQ) for young children and the Baecke questionnaire on habitual physical activity, modified especially for children, were completed by the parents. We examined both the development of the TF angle and the IM distance in relation to age and the degree of restriction of physical activity in relation to the severity of the genu valgum. We analysed 316 unaffected lower extremities in children aged 3-9 years. The average value of the TF angle starts around 7° at the age of 3 years and gradually decreases to 4° at the age of 7-8 years. The average value of the IM distance ranges over 3.5 cm at the age of 3 years and progressively decreases to 2 cm at the age of 7-8 years. Physical activity appears to be influenced by sex and the severity of the genu valgum. We provide age-specific values for limb alignment and joint orientation of the lower extremity in children aged 3-9 years. A statistical correlation between all indexes (sport, leisure time and total) of the Baecke and the NPAQs and measurements of genu valgum was noted depending on the severity of the valgus deformity.

The aims of this study were (1) to determine minutes of moderate-to-vigorous physical activity (PA) and vigorous PA accrued in youth sport football (also internationally referred to as soccer), and the contribution toward daily weekend moderate-to-vigorous PA and vigorous PA for males aged 9-16 years, and (2) to investigate variability in these outcomes related to age and playing position. One hundred and nine male grassroots footballers (Mean age = 11.98 ± 1.75 years) wore a GT3× accelerometer for 7 days. Weekend youth sport football participation and playing position were recorded. Youth sport football moderate-to-vigorous PA (M = 51.51 ± 17.99) and vigorous PA (M = 27.78 ± 14.55) contributed 60.27% and 70.68% toward daily weekend moderate-to-vigorous PA and vigorous PA, respectively. Overall, 36.70% of participants accumulated ≥60 min moderate-to-vigorous PA and 69.70% accrued ≥ 20 min of vigorous PA during youth sport. For participants aged 13 to16 years, youth sport football moderate-to-vigorous PA and vigorous PA were significantly higher, and contributed a greater amount toward daily weekend moderate-to-vigorous PA and vigorous PA than for participants aged 9-12 years (p = <.01). Youth sport football is an important source of moderate-to-vigorous PA and vigorous PA at the weekend for male youth, and particularly for adolescents. Participation may offer opportunity for weekend engagement in vigorous PA toward health enhancing levels.

Objective To investigate the prevalence of acquired undescended testis (UDT) in Dutch schoolboys. Design and participants As a part of routine school medical examinations, during a 2‐year period (2001–3), testis position was determined in 6‐year, 9‐year and 13‐year‐old schoolboys. Before the examination, a parent questionnaire was sent inquiring both about the position of the testes and whether the child had been admitted earlier to hospital for orchidopexy. In 6‐year and 13‐year olds, a physical examination was performed by the school medical officer; in 9‐year olds, a school nurse interview was held. Each boy for whom there was any doubt of the scrotal position was referred to the hospital for examination of both testes. Setting Institution for Youth Health Care “Noordkennemerland” and Medical Centre Alkmaar, Alkmaar, the Netherlands. Results Testis position was determined in 2042 boys aged 6, 1038 aged 9 and 353 aged 13. Of these, 47, 53 and 8 boys, respectively, were referred to the hospital and seen for further evaluation. The diagnosis of acquired UDT was made in 25 boys aged 6, 23 aged 9 and four aged 13. In 33 boys, a congenital UDT was diagnosed; 32 (97%) had already been diagnosed and treated at an early age. Conclusions The prevalence of acquired UDT for 6‐year, 9‐year and 13‐year olds was, respectively, 1.2% (25/2042), 2.2% (23/1038) and 1.1% (4/353). In addition, congenital UDT is treated during the early years of life and, in contrast with popular belief, screening programmes for detecting UDT in the early years are successful. PMID:16905567

Corymbia (a eucalypt) is an important forestry genus and a potential lignocellulosic bioenergy feedstock. The composition of the lignocellulosic cell wall significantly impacts pretreatment efficiency and conversion to biofuel but is variable and changes with age. In this study, we estimated Klason lignin content, composition, and monosaccharide (glucose and xylose) release after enzymatic saccharification of untreated and hydrothermally pretreated biomass from Corymbia parental species Corymbia torelliana (CT), Corymbia citriodora subsp. variegata (spotted gum; CCV), and interspecific F1 hybrids (CT x CCV) at ages 9 and 12 years from planting. Analysis of lignin composition derived from syringyl/guaiacyl monolignols (S/G) found significantmore » differences among taxa, with CT S/G ratios (2.2 and 2.0) being significantly lower than CCV (2.6 and 2.3) or hybrids (2.5 and 2.3) at ages 9 and 12 respectively. In general, enzymatic saccharification yields from untreated biomass were significantly different among taxa, with CT (113 and 75 mg g -1) and hybrids (108 and 81 mg g -1) yielding significantly higher glucose from untreated biomass than CCV (82 and 56 mg g -1) at ages 9 and 12 respectively. Comparison of traits within taxa between ages 9 and 12 found S/G ratios and glucose yields from untreated biomass were significantly lower in CT, CCV and hybrid taxa. As a result, the formation of lignocellulosic cell walls is complex, influenced by genetics and age of material, requiring optimization of rotation age for biofuel production and other industrial processes.« less

INTRODUCTION Neurofibromatosis 1 is one of the most common heritable genetic disorders in humans. It is characterized by formation of neurofibromas, with marked variability in expression. Half the cases are due to autosomal dominant inheritance; the rest arise from de novo mutations. Prevalence varies by population, and prevalence in Cuba is unknown. OBJECTIVE Determine the prevalence of neurofibromatosis 1 in a population of Cuban children aged 9-11 years old in Pinar del Río Province, Cuba. METHODS A descriptive cross-sectional study was carried out in Pinar del Río Province in 2004, in which 19,392 children were assessed for neurofibromatosis 1. The study was conducted in two phases: the first, a survey of the entire population aged 9-11 years by genetic counselors in the province's schools; the second, assessment by clinical geneticists of children who met criteria for referral to the Provincial Medical Genetics Center. Neurofibromatosis 1 cases and first-degree relatives were examined to identify the origin of the mutation (de novo or inherited). Neurofibromatosis 1 prevalence was calculated, as well as history of a first-degree relative with the disease and frequency of several principal clinical signs-café au lait spots, freckles in places unexposed to sunlight, presence of neurofibromas, Lisch nodules and characteristic bone lesions. RESULTS Of the eligible population, 99.3% was screened (10,034 boys and 9358 girls). Active case finding resulted in referral of 200 children to medical geneticists and the disease was confirmed in 17, for a prevalence of one case per 1141 children aged 9-11 years old. Café au lait spots were the most frequent sign (100%), followed by freckles in areas unexposed to sunlight (82.4%) and characteristic bone lesions (41.2%). Only 4 of the 17 cases were previously being treated for the disease. CONCLUSIONS Neurofibromatosis 1 has high prevalence in the group studied in Pinar del Rio Province and most cases are not detected in

In order to understand the risk of polybrominated diphenyl ethers (PBDEs) existing in sediment for years, the accumulation of PBDEs in sediment aged for 2 years to fish was investigated. Simulated aquatic system microcosms were conducted with PBDE contaminated sediment aged for 2 years and carps were cultured in the microcosms for 20 days. PBDE concentrations in carp tissues were analyzed to estimate the bioavailability of aged PBDEs in carps. The main spiked PBDE congeners were detected in sediment even though the contaminated sediment was aged for 2 years. Similarly, the five PBDE (BDE-28, 47, 100, 153 and 154) congeners which probably were bioaccumulated by carp were detected in fish tissues, indicating that PBDEs could be bioaccumulated after aging for 2 years. The PBDEs distribution revealed that the concentrations of polybrominated diphenyl ethers in tissues of Cyprinus carpio is in this order of magnitude: gut > liver > gill > fillet. The PBDEs concentrations in fillet were as high as 67.9 ng/g dry wt, in which BDE-47 contributed almost 50% in profile.

Capsular contracture (CC) is a major complication of breast surgery with smooth and textured implants. Polyurethane (PU) foam-coated breast implants were developed to decrease the incidence of CC. The authors determined the incidence of CC following 2-stage breast reconstruction using PU foam-covered implants, with and without radiation therapy. The records of 92 patients who received 115 PU implants were retrospectively reviewed. The rates of CC over time were compared for irradiated and nonirradiated groups with a Kaplan-Meier analysis and log-rank test. CC rates also were analyzed with respect to age. The median follow-up time for patients was 103.3 months. Nine patients experienced unilateral Baker grade III or IV fibrous CC, including 6 patients from the irradiated group and 3 patients from the nonirradiated group. The overall cumulative incidence of CC at 9 years was 8.1%. In the irradiated and nonirradiated groups, the 9-year cumulative incidence was 10.7% and 5.5%, respectively. CC occurred within 3 years in the irradiated group and within 7 years in the nonirradiated group. The incidence of CC appeared to be higher among younger patients. Radiation therapy increases the risk of high-grade CC with textured or smooth implants. PU implants are associated with a much lower cumulative incidence of CC following 2-stage breast reconstruction, even when radiotherapy is performed.

Background Generating percentile values is helpful for the identification of children with specific fitness characteristics (i.e., low or high fitness level) to set appropriate fitness goals (i.e., fitness/health promotion and/or long-term youth athlete development). Thus, the aim of this longitudinal study was to assess physical fitness development in healthy children aged 9–12 years and to compute sex- and age-specific percentile values. Methods Two-hundred and forty children (88 girls, 152 boys) participated in this study and were tested for their physical fitness. Physical fitness was assessed using the 50-m sprint test (i.e., speed), the 1-kg ball push test, the triple hop test (i.e., upper- and lower- extremity muscular power), the stand-and-reach test (i.e., flexibility), the star run test (i.e., agility), and the 9-min run test (i.e., endurance). Age- and sex-specific percentile values (i.e., P10 to P90) were generated using the Lambda, Mu, and Sigma method. Adjusted (for change in body weight, height, and baseline performance) age- and sex-differences as well as the interactions thereof were expressed by calculating effect sizes (Cohen’s d). Results Significant main effects of Age were detected for all physical fitness tests (d = 0.40–1.34), whereas significant main effects of Sex were found for upper-extremity muscular power (d = 0.55), flexibility (d = 0.81), agility (d = 0.44), and endurance (d = 0.32) only. Further, significant Sex by Age interactions were observed for upper-extremity muscular power (d = 0.36), flexibility (d = 0.61), and agility (d = 0.27) in favor of girls. Both, linear and curvilinear shaped curves were found for percentile values across the fitness tests. Accelerated (curvilinear) improvements were observed for upper-extremity muscular power (boys: 10–11 yrs; girls: 9–11 yrs), agility (boys: 9–10 yrs; girls: 9–11 yrs), and endurance (boys: 9–10 yrs; girls: 9–10 yrs). Tabulated percentiles for the 9-min run test

the study, we administered 18 780 doses of LAIV-T to 11 096 children. A total of 4529, 7036, and 7215 doses of LAIV-T were administered to children who were 18 months to 4 years, 5 to 9 years, and 10 to 18 years of age, respectively. In vaccination years 1, 2, 3, and 4, we identified 10, 15, 11, and 6 SAEs, respectively. None of the SAEs was attributed to LAIV-T. In vaccination years 1, 2, 3, and 4, we identified 3, 2, 1, and 0 pregnancies, respectively, among adolescents. All delivered healthy infants. The RR for MAARI from 0 to 14 and 15 to 42 days after LAIV-T was assessed in vaccinees during the 4 vaccine years. Compared with the prevaccination period, there was no significant increase in risk in health care utilization attributed to MAARI from 0 to 14 and 15 to 42 days after vaccination in children who were 18 months to 4 years, 5 to 9 years, and 10 to 18 years of age in the 4 vaccine years. In children who were 18 months to 4 years of age, there was no significant increase in the risk in health care utilization for MAARI, MAARI subcategories (otitis media/sinusitis, upper respiratory tract illness, and lower respiratory tract illness), and asthma during the 0 to 14 days after vaccination compared with the prevaccination period. No significant increase in the risk in health care utilization for MAARI, MAARI subcategories, and asthma was detected when the risk period was extended to 15 to 42 days after vaccination, except for asthma events in vaccine year 1. A RR of 2.85 (95% confidence interval [CI]: 1.01–8.03) for asthma events was detected in children who were 18 months to 4 years of age but was not significantly increased for the other 3 vaccine years (vaccine year 2, RR: 1.42 [95% CI: 0.59–3.42]; vaccine year 3, RR: 0.47 [95% CI: 0.12–1.83]; vaccine year 4, RR: 0.20 [95% CI: 0.03–1.54]). No significant increase in the risk in health care utilization for MAARI or asthma was observed in children who were 18 months to 18 years of age and received 1, 2, 3

Bullying and being exposed to bullying among children is prevalent, especially among children with psychiatric symptoms, and constitutes a major concern worldwide. Whether childhood bullying or exposure to bullying in the absence of childhood psychiatric symptoms is associated with psychiatric outcomes in adulthood remains unclear. To study the associations between bullying behavior at 8 years of age and adult psychiatric outcomes by 29 years of age. Nationwide birth cohort study of 5034 Finnish children with complete information about childhood bullying behavior was followed up from 8 to 29 years of age. Follow-up was completed on December 31, 2009, and data were analyzed from January 15, 2013, to February 15, 2015. Information about bullying, exposure to bullying, and psychiatric symptoms were obtained from parents, teachers, and child self-reports when children were 8 years of age. Use of specialized services for psychiatric disorders from 16 to 29 years of age was obtained from a nationwide hospital register, including outpatient and inpatient treatment. Among the 5034 study participants, 4540 (90.2%) did not engage in bullying behavior; of these, 520 (11.5%) had received a psychiatric diagnosis at follow-up; 33 of 166 (19.9%) who engaged in frequent bullying, 58 of 251 (23.1%) frequently exposed to bullying, and 24 of 77 (31.2%) who both frequently engaged in and were frequently exposed to bullying had received psychiatric diagnoses at follow-up. When analyses were adjusted by sex, family factors, and child psychiatric symptoms at 8 years of age, we found independent associations of treatment of any psychiatric disorder with frequent exposure to bullying (hazard ratio [HR], 1.9; 95% CI, 1.4-2.5) and being a bully and exposed to bullying (HR, 2.1; 95% CI, 1.3-3.4). Exposure to bullying was specifically associated with depression (HR, 1.9; 95% CI, 1.2-2.9). Bullying was associated with psychiatric outcomes only in the presence of psychiatric problems at 8 years

Objective: To explore the prevalence of physical activity time <1 hour and related factors in students aged 9-22 years in China. Methods: A total of 220 159 students (110 039 boys and 110 120 girls) aged 9-22 years who completed the questionnaire of physical activity and lifestyle behaviors were selected from " 2014 National Physical Fitness and Health Surveillance" for the current study. All the participants were divided into 2 groups, i.e. physical activity time <1 hour and physical activity time ≥1 hour according the suggestion of Central Government, stratified by age and gender. χ (2) tests were used to compare the difference in the prevalence of physical activity time <1 hour between boys and girls in every age groups. Univariate and multivariate log-binomial regression models were used to explore the factors that influenced the prevalence of physical activity time <1 hour. Results: The boy's prevalence of physical activity time <1 hour was 73.3%, with the lowest (57.0%) in 9-years-old group, and highest (82.5%) in 18 years old group. The girl's prevalence of physical activity time <1 hour was 79.1%, with the lowest (60.1%) in 9-years-old group, and highest (89.8%) in 21 years old group. Overall, The prevalence of physical activity time <1 hour was significantly higher in girls than in boys ( P <0.001), and the prevalence were significantly higher in girls than in boys in all the age groups ( P <0.001), and it was observed that the prevalence of physical activity <1 hour increased with age in both boys and girls ( P <0.001). Multivariate log-binomial regression model found that being girl ( PR =1.05, 95 %CI : 1.05-1.06), parents' disliking children to participate physical activity ( PR =1.08, 95 % CI : 1.07-1.09), heavy homework ( PR =1.13, 95 % CI : 1.12-1.14), long homework time ( PR =1.08, 95 %CI : 1.07-1.08), long time spending on electronic screen watching ( PR =1.01, 95 %CI : 1.00-1.01) and disliking physical class ( PR =1.11, 95 %CI : 1

To determine if time spent in objectively measured sedentary behavior is associated with a change in body mass index (BMI) between ages 9 and 15 years, adjusting for moderate-to-vigorous physical activity (MVPA). Prospective observational study of children at ages 9 (2000), 11 (2002), 12 (2003) and 15 years (2006). Longitudinal quantile regression was used to model the influence of predictors on changes at the 10th, 25th, 50th, 75th and 90th BMI percentiles over time. Participants were enrolled in the National Institute of Child Health and Human Development (NICHD) Study of Early Child Care and Youth Development and include both boys and girls (n=789). Objectively measured BMI (kg m(-2)) was the outcome variable and objectively measured sedentary behavior was the main predictor. Adjustment was also made for MVPA, gender, race, maternal education, hours of sleep and healthy eating index. Increases in BMI were observed at all percentiles, with the greatest increase observed at the 90th BMI percentile. Spending more time in sedentary behavior (h per day) was associated with additional increases in BMI at the 90th, 75th and 50th BMI percentiles, independent of MVPA and the other covariates (90th percentile=0.59, 95% confidence interval (95% CI): 0.19-0.98 kg m(-2); 75th percentile=0.48, 95% CI: 0.25-0.72 kg m(-2); and 50th percentile=0.19, 95% CI: 0.05-0.33 kg m(-2)). No associations were observed between sedentary behavior and changes at the 25th and 10th BMI percentiles. Sedentary behavior was associated with greater increases in BMI at the 90th, 75th and 50th BMI percentiles between ages 9 and 15 years, independent of MVPA. Preventing an increase in sedentary behavior from childhood to adolescence may contribute to reducing the number of children classified as obese.

To correlate different methods of body composition assessment in overweight or obese schoolchildren, using deuterium oxide (D2O) dilution as a reference. Percentage of total body water (%TBW), fat free mass (%FFM), and body fat (%BF) were assessed by D2O and tetrapolar electrical bioimpedance analysis (BIA) in 54 obese and overweight students aged 6-9 years. Skinfold thickness (ST), body mass index (BMI), conicity index (CI), waist circumference (WC), waist-to-height ratio (WHtR), and waist-to-hip (WHR) ratio were also used. Mean values for body composition were 38.4%±8.4% BF, 44.9%±6.1% TBW and 61.6%±8.4% FFM. There was no significant difference in body weight, body fat mass (FM), TBW, and FFM between genders. Regarding D2O, ST underestimated %BF, and overestimated %FFM in both genders (p<0.05). BIA overestimated %TBW in the group as a whole and in males (p<0.05). The only positive and strong correlations occurred in females regarding the WC (σ=0.679), CI (r=0.634), and WHtR (r=0.666). In this sample of obese and overweight children, there were strong correlations between body composition measured by D2O and some indices and anthropometric indicators in females, but there was no positive and strong correlation of fat tissue with the indices/indicators at all ages and in both genders.

The aim of this study was to examine siblings' experiences of their brother's or sister's cancer death and if these experiences influenced levels of anxiety 2-9 years later. This nationwide survey was conducted in Sweden in 2009. All siblings who had a brother/sister who was diagnosed with cancer before the age of 17 years and who died before the age of 25 years during 2000-2007 were invited. Of those, 174 siblings participated (participation rate: 73%). Mixed data from the survey about the siblings' experiences of death were included as well as data from the Hospital Anxiety and Depression Scale. To examine the experiences, descriptive statistics and content analysis were used. Mann-Whitney U-test was conducted to investigate if the experiences influenced anxiety 2-9 years later. The siblings reported poor knowledge and experienced a lack of communication about their brother's/sister's death, for example, about the time frame, bodily changes near death, and about their own experiences. Siblings who reported that no one talked with them about what to expect when their brother/sister was going to die reported higher levels of anxiety 2-9 years after the loss. Seventy percent reported that they witnessed their brother/sister suffering in the last hours in life. Many of those who were not present during the illness period and at the time of death expressed regret. It is important to prepare siblings for their brother's/sister's illness and death as it may decrease anxiety and regrets later on. Copyright © 2015 John Wiley & Sons, Ltd.

Historical decreases in sleep duration in children have been documented worldwide; however, there is sparse information on sleep duration in differing cultural regions. We assess sleep duration and its trends for children in Spain from 1987 to 2011 and associated sociodemographic characteristics. Data from eight Spanish National Health Surveys, from 1987 to 2011, were collected on parent-reported sleep duration and associated socio-demographic characteristics including age, sex, parental level of education, child body mass index (BMI), and physical activity. A total of 24,867 children aged 2-14 years were included in the final sample. Overall, short sleep duration increased to 44.7% from 29.8% in 1987. Decreasing sleep duration trends were found in all demographic groups, decreasing by around 20 minutes in 24 hours from 1987 to 2011; decreasing to 10 hours 16 minutes in 2- to 5-year olds, 9 hours 31 minutes in 6- to 9-year-olds, and 8 hours 52 minutes in 10- to 14-year-olds. No difference in sleep duration was found between girls and boys. Sleep duration was associated with year of survey, age, level of parental education, obesity, and exercise. Almost 45% of children in Spain are not sleeping the recommended amount. Regional differences in sleep attitudes and duration alongside a lack of consistency in cut-offs for age-appropriate ideal sleep in literature is a barrier for international comparison and highlights the need for research in physiological sleep requirements. With the association of short sleep duration with many different health outcomes, sleep should be considered as a modifiable lifestyle factor and a public health issue. Copyright © 2016 Elsevier B.V.

Trajectories of children's externalizing behavior were examined using multilevel growth curve modeling of data from the NICHD Study of Early Child Care and Youth Development. According to ratings by both mothers and caregivers/teachers when children were 2, 3, 4, 7, and 9 years old, externalizing behavior declined with age. However, mothers rated children as higher in externalizing behavior than did caregivers and teachers. Higher levels of age 9 externalizing behavior were predicted by the following factors: child male gender (for caregiver/teacher reports only), infant difficult temperament (for children with harsh mothers only), harsher maternal attitude toward discipline, higher level of maternal depression (for maternal reports only), and lower level of maternal sensitivity (especially for boys). Caregivers and teachers reported higher levels of externalizing behavior in African American children than in European American children, increasingly so over time; mothers' ratings revealed the reverse. The declining slope of externalizing behavior was predicted by infant difficult temperament for mother reports only. Additional analyses suggested that the association between parenting and externalizing behavior was bidirectional. (PsycINFO Database Record (c) 2008 APA, all rights reserved).

The Stability of Genetic Determination from Age 2 to Age 9: A Longitudinal Twin Study.

It is important to understand whether type 2 diabetes mellitus (T2DM) is increasing in childhood for health-care planning and clinical management. The aim of this study is to examine the incidence of T2DM in New Zealand children, aged <15 years from a paediatric diabetes centre, Auckland, New Zealand. Retrospective analysis of prospectively collected data from a population-based referral cohort from 1995 to 2015. Hundred and four children presented with T2DM over the 21-year period. The female:male ratio was 1.8:1, at mean (standard deviation) age 12.9 (1.9) years, body mass index standard deviation score +2.3 (0.5), blood sugar 15.3 (8.5) mmol/L, HbA1c 76 (28) mmol/mol. At diagnosis, 90% had acanthosis nigricans and 48% were symptomatic. In all, 33% were Maori, 46% Pacific Island, 15% Asian/Middle Eastern and 6% European. There was a progressive secular increase of 5% year on year in incidence. The overall annual incidence of T2DM <15 years of age was 1.5/100 000 (1.2-1.9) (95% confidence interval), with higher rates in Pacific Island (5.9/100 000) and Maori (4.1/100 000). The incidence of T2DM in children <15 years of age in New Zealand has increased progressively at 5%/year over the last 21 years. The risk was disproportionately associated with girls and children from high-risk ethnic groups. © 2018 Paediatrics and Child Health Division (The Royal Australasian College of Physicians).

The present study aimed to analyse the nutritional quality of childrens' breakfasts using data collected during a cross-sectional observational study on the prevalence of urinary osmolality in 529 French children aged 9-11 years. Total nutrient intake, mean adequacy ratio (MAR), energy density and solid energy density were calculated from breakfast food and fluid nutritional composition. To identify the main qualitative breakfast patterns, each breakfast item was categorised into 15 solid and liquid food categories and a principal component analysis followed by a cluster analysis was performed. Only 9.8% included skipped breakfast. Breakfast provided, on average, 22.9% of the recommended daily energy intake and 24.7% of the mean adequacy ratio of 23 key nutrients. Four breakfast patterns were identified: 'Sweets breakfast' (40.0% of children), 'Traditional French breakfast' (27.2%), 'Ready-to-eat cereal (RTEC) + milk' (18.1%) and 'Dairy and juice breakfast' (9.5%). Nutritionally, the 'RTEC + milk' pattern was the most advantageous. Flavoured milk was the most frequently consumed food (50.5%) and the major component of the 'Traditional French breakfast'. Although breakfast provided a substantial contribution to a range of nutrients, opportunity for improvement, particularly to less nutrient breakfast patterns, should not be overlooked. © 2016 The British Dietetic Association Ltd.

Perform calculation of the economical effectiveness of realization of a program of vaccination of children aged 2 years against chickenpox (CP) in the Russian Federation. Data of Federal service on customers rights protection and human well-being surveillance on evaluation of morbidity and losses caused by CP in the Russian Federation in 2008 - 2010 were used. A cohort of children (1 760 000) aged 2 years subject to vaccination against CP in 2011, evaluation of cost of 1 case of the infection, the amount of losses per vaccination of 1 child were approximately determined; analysis of prevented losses by implementation ofvaccination program by using mathematical modeling methods was performed. Without vaccination program in the Russian Federation the cost of losses per 1 case of CP related to hospitalization and outpatient visits as well as temporary disability of one of the parent in various age groups was: for children aged 1 - 2 years--8 333 RUB (Russian rubles), 3 - 6 years--21 171 RUB, 7 - 14 years--21 295 RUB. The cost of vaccination against CP of 1 child including 2 doses of vaccines with physician examination and vaccination procedure would be 1600 RUB. In the case of realization of vaccination program against CP in 2011 of children aged 2 years its cost would be 2 488.9 million RUB. Cost prevention already exceeds the cost of vaccination in 1 age cohort of children at year 2 and in 5 years the amount of prevented losses would exceed 15 billion RUB per 1 vaccinated cohort and would continue to increase steadily. The performed calculations show that vaccination against CP in the Russian Federation is a highly efficient investment. Self-sufficiency of a program implemented in 2011 may be obtained already at the start of year 2 after the realization and by 2016 the net economical benefit would be around 8 milliards RUB.

Rapid growth, possibly occurring in critical periods in early life, may be important for the development of obesity. It is unknown whether this is influenced by postnatal exposures such as age-relevant sources of stress. Frequent house moves may be one such stressor. We aimed to examine if there is a period of growth in early life critical for the development of child obesity by age 9 years and assess the role of house moves in modifying any relationships between early life growth and obesity at age 9 years. Prospective Australian birth cohort study. In all, 392 children with serial body size measurements from birth to age 9 years. Standardized body mass index (z-BMI) was available for six time points (spanning birth to 3½ years), and the total number of house moves between birth and 3½ years. The outcomes considered were z-BMI and % body fat (%BF) at age 9 years. Linear regression models were used to estimate the effects of serial measurements of z-BMI and number of house moves on the outcomes. Life-course plots showed that z-BMI at 3½ years was a statistically significant predictor of z-BMI at 9 years (β=0.80; standard error (s.e.), 0.04), whereas z-BMI at 9 months (β=-1.13; s.e., 0.40) and 3½ years (β=4.82; s.e., 0.42) were significant predictors of %BF at age 9 years. There were statistically significant interactions between the number of house moves and change in z-BMI between 9 and 12 months, such that ≥ 3 house moves in early life amplified the detrimental effects of earlier rapid growth on both body size and composition at age 9 years. In the absence of evidence for a single critical period, efforts to prevent overweight and obesity are required throughout childhood. In addition, modifiable postnatal stressors may exacerbate effects of early growth on obesity in later childhood.

Dietary sugar intake, particularly added sugar and sugar-sweetened beverages, has received worldwide attention recently. Investigation of dietary behaviors may facilitate understanding of dietary sugar intakes of children and adolescents. However, the relationship between dietary sugar intake and dietary behaviors in the Korean population has not been investigated. Thus, this study aimed to estimate dietary sugar intake and food sources according to sex as well as examine the relationship of dietary sugar intake with frequent snacking and dietary patterns among Korean children and adolescents. We pooled data from five studies involving Korean children and adolescents conducted from 2002 to 2011. A total of 2,599 subjects aged 9-14 years were included in this study. Each subject completed more than 3 days of dietary records. Mean daily total sugar intake was 46.6 g for boys and 54.3 g for girls. Compared with boys, girls showed higher sugar intakes from fruits (7.5 g for boys and 8.8 g for girls; P = 0.0081) and processed foods (27.9 g for boys and 34.9 g for girls; P < 0.0001). On average, 95.4% of boys and 98.8% of girls consumed snacks during the study period, and total sugar intake showed a significantly increasing trend with increasing energy intake from snacks ( P < 0.0001 for both sexes). Two dietary patterns were identified by cluster analysis: Traditional and Westernized patterns. Total sugar intake was higher in the Westernized pattern (56.2 g for boys and 57.2 g for girls) than in the Traditional pattern (46.5 g for boys and 46.3 g for girls). These results suggest that multilateral and practical development of a nutrition education and intervention program that considers dietary behaviors as well as absolute sugar intake is required to prevent excessive sugar intake in Korean children and adolescents.

Few studies have investigated differences in age- and gender-specific educational gradients in tobacco smoking among the whole range of adult age groups. We examined educational inequality in smoking among Japanese adults aged 25-94 years. Using a large nationally representative sample (167,925 men and 186,588 women) in 2010, prevalence of current smoking and heavy smoking among daily smokers and their inequalities attributable to educational attainment were analyzed according to sex and age groups. Among men aged 25-34 years, junior high school graduates had the highest current smoking prevalence at 68.4% (95% confidence interval [CI], 66.0%-70.6%), and graduate school graduates had the lowest at 19.4% (95% CI, 17.2%-21.9%). High school graduates had the second highest current smoking prevalence (e.g., 55.9%; 95% CI, 54.9%-56.8% in men aged 25-34 years). Among men aged 75-94 years, the difference in current smoking across educational categories was small. A similar but steeper educational gradient in current smoking was observed among women. Among women aged 25-34 years, junior high school graduates had the highest current smoking prevalence at 49.3% (95% CI, 46.3%-52.3%), and graduate school graduates had the lowest at 4.8% (95% CI, 2.9%-7.4%). Compared with older age groups, such as 65-94 years, younger age groups, such as 25-54 years, had higher estimates of inequality indicators for educational inequality in both current and heavy smoking in both sexes. Educational inequalities in current and heavy smoking were apparent and large in the young population compared with older generations. The current study provides basic data on educational inequalities in smoking among Japanese adults. Copyright © 2016 The Authors. Production and hosting by Elsevier B.V. All rights reserved.

A longitudinal, multilevel analysis of homicide against children aged 0-9 years using state-level characteristics: 1979-2007.

Annually, over a thousand children are the victims of homicide in the United States Homicide among younger children, 0-9 years of age, is usually perpetrated by parents and caregivers. Researchers neither have tracked changes in the homicide rate among young children over time nor have they used theory to understand what factors may drive these changes. In this analysis of state-level data, we used longitudinal growth modeling and ecological theory to examine changes in homicide rate against children aged 0-9 years from 1979 to 2007. Our results indicate that states are relatively consistent, over time, in their homicide rates. Furthermore, a cultural context of criminal and risky behavior is positively associated with homicide against children. We discuss implications for future research and prevention.

To describe demographic, therapeutic and follow-up data of four cases of renal cell carcinoma with Xp11.2 translocation in adults older than 50 years of age. Between January 2008 and December 2011, 170 patients underwent surgery for renal cell carcinoma in our center. Systematic histopathologic analysis of specimen removed was performed. Complementary immunohistochemical analysis was performed only in cases with uncertain diagnosis or in patients younger than 40 years of age. Among these 170 patients with a median age of 59years old (21-89), immunohistochemistry helped find a TFE3 translocation in four cases (2.4%). There were three women and one man of 53, 71, 75 and 86years old respectively. One patient was metastatic at diagnosis. Radical nephrectomy was first performed in all cases. TNM staging was T3aN2R0, T3bN0R0, T2N2R0 and T3aN2R2, with a Furhman grade of 4. Two patients progressed with metastasis 5 and 7months after surgery, and two with lymphatic invasion 2 and 9months after nephrectomy. One patient died during follow-up. Xp11.2 translocation renal cell carcinoma was uncommon after 50years of age in our series, but probably under estimated. It seemed to be associated with a poor prognosis. Larger studies must be performed to optimize its specific treatment. Copyright © 2012 Elsevier Masson SAS. All rights reserved.

Abstract Background. We previously reported the noninferiority 1 month after the last dose of 2-dose human papillomavirus 16/18 AS04-adjuvanted (AS04-HPV-16/18) vaccine schedules at months 0 and 6 (2D_M0,6) and months 0 and 12 (2D_M0,12) in girls aged 9–14 years compared with a 3-dose schedule at months 0, 1, and 6 (3D_M0,1,6) in women aged 15–25 years. Here, we report the results at study end (month 36 [M36]). Methods. Girls were randomized 1:1 and received 2 vaccine doses either 6 months (2D_M0,6) or 12 months apart (2D_M0,12); women received 3 doses at months 0, 1, and 6 (3D_M0,1,6). Endpoints included noninferiority of HPV-16/18 antibodies for 2D_M0,6 versus 3D_M0,1,6; 2D_M0,12 versus 3D_M0,1,6; and 2D_M0,12 versus 2D_M0,6; and assessment of neutralizing antibodies, T cells, B cells, and safety. Results. At M36, the 2D_M0,6 and 2D_M0,12 schedules remained noninferior to the 3D_M0,1,6 schedule in terms of seroconversion rates and 3D/2D geometric mean titers for anti-HPV-16 and anti-HPV-18. All schedules elicited sustained immune responses up to M36. Conclusions. Both 2-dose schedules in young girls remained noninferior to the 3-dose schedule in women up to study conclusion at M36. The AS04-HPV-16/18 vaccine administered as a 2-dose schedule was immunogenic and well tolerated in young girls. PMID:28591778

Influencing the parents of children aged 9-13 years: findings from the VERB campaign.

The CDC's VERB campaign was designed to increase physical activity among children aged 9-13 years (tweens). As part of the strategy to surround tweens with support to be physically active, VERB developed messages for parents, the secondary target audience, to encourage them to support their tween's physical activity. Multiple regression analyses were conducted to determine whether parent awareness of VERB was a significant predictor of seven factors that related to parental attitudes, beliefs, and supportive behaviors for tweens' physical activity using the Youth Media Campaign Longitudinal Survey (YMCLS). Parents (N=1946) of U.S. children aged 9-13 years. Advertising directed at tweens through paid television, radio, print, Internet, and schools was the primary VERB intervention; tween advertising could have been also seen by parents. Messages directed at parents encouraging their support of tweens' physical activity were delivered in English through mainly print and radio. In-language messages for Latino and Asian audiences were delivered through print, radio, television, and at events. Parents' awareness of VERB; parents' attitudes, beliefs, and support for their tweens' physical activities. Awareness increased each year of the campaign; more than 50% of parents were aware of VERB by the third year of the campaign. Parents reported that their main source of awareness was television, the main channel used to reach tweens. Awareness of VERB was predictive of positive attitudes about physical activity for all children, belief in the importance of physical activity for their own child, and the number of days parents were physically active with their child. Parents' awareness of VERB was associated with positive attitudes, beliefs, and behavior. Parents' awareness probably resulted from a combination of messages directed to parents and tweens. To maximize audience reach, social marketers who are developing health messages should consider the potential value of

Age has been suggested as a negative prognostic factor for hip arthroscopy. The purpose of this study was to compare patient characteristics and outcomes after hip arthroscopy in patients aged 50 years or older with a matched control group of patients aged 30 years or younger at a minimum postoperative follow-up of 2 years. Between September 2008 and March 2010, data were prospectively collected on all patients aged 50 years or older undergoing primary hip arthroscopy. Fifty-two patients met our inclusion and matching criteria, of whom all 52 (100%) were available for follow-up at a minimum of 2 years. This cohort was compared with a matched-pair control group of patients aged 30 years or younger who underwent similar procedures. The mean age of the study group was 54.8 years (range, 50 to 69 years), and that of the control group was 20.3 years (range, 13 to 30 years). The groups were matched at a 1:1 ratio, including 18 male patients (34.6%) and 34 female patients (65.4%) in each group, with a mean follow-up period of 32 months (range, 24 to 54 months). In the younger control group, the score improvement from preoperatively to 2 years' follow-up was 62.9 to 84.2 for the modified Harris Hip Score, 60.5 to 84.2 for the Non-Arthritic Hip Score, 63.1 to 86.5 for the Hip Outcome Score-Activities of Daily Living, and 42.2 to 72.7 for the Hip Outcome Score-Sport-Specific Subscale. In the older study group, the score improvement from preoperatively to 2 years' follow-up was 61.2 to 82.2 for the modified Harris Hip Score, 59.9 to 80.4 for the Non-Arthritic Hip Score, 63.9 to 83 for the Hip Outcome Score-Activities of Daily Living, and 41.2 to 64.6 for the Hip Outcome Score-Sport-Specific Subscale. All improvements in both groups were statistically significant at the 2-year postoperative follow-up (P < .001). There was no significant difference for all patient-reported outcome (PRO) scores at final follow-up between both groups. When we compared the change in PRO scores (�

Head impact exposure in youth football has not been well-documented, despite children under the age of 14 accounting for 70% of all football players in the United States. The objective of this study was to quantify the head impact exposure of youth football players, age 9-12, for all practices and games over the course of single season. A total of 50 players (age = 11.0 ± 1.1 years) on three teams were equipped with helmet mounted accelerometer arrays, which monitored each impact players sustained during practices and games. During the season, 11,978 impacts were recorded for this age group. Players averaged 240 ± 147 impacts for the season with linear and rotational 95th percentile magnitudes of 43 ± 7 g and 2034 ± 361 rad/s(2). Overall, practice and game sessions involved similar impact frequencies and magnitudes. One of the three teams however, had substantially fewer impacts per practice and lower 95th percentile magnitudes in practices due to a concerted effort to limit contact in practices. The same team also participated in fewer practices, further reducing the number of impacts each player experienced in practice. Head impact exposures in games showed no statistical difference. While the acceleration magnitudes among 9-12 year old players tended to be lower than those reported for older players, some recorded high magnitude impacts were similar to those seen at the high school and college level. Head impact exposure in youth football may be appreciably reduced by limiting contact in practices. Further research is required to assess whether such a reduction in head impact exposure will result in a reduction in concussion incidence.

The purpose of this study was to investigate the efficacy of intravitreal aflibercept for neovascular age-related macular degeneration (nAMD) in very elderly patients aged 90 years or older at 2 years after treatment initiation. In this multicentre retrospective data analysis from electronic medical record, consecutive treatment-naive patients with nAMD treated with aflibercept with at least 2 years follow-up were stratified into those aged < 90 years (Group I) and an older cohort aged 90 and over (Group II). We compared the visual acuity (EDTRS letters) outcomes at 4 weekly intervals between the two groups over a 2-year period. The mean visual acuity of Group I at presentation was 56.3 ETDRS letters versus 52.8 letters in Group II. Maximal visual acuity was achieved in both the groups by 6 months after initiating treatment (4.7 vs. 4.0 letters gain). By 2 years, the mean visual acuity of the older cohort fell marginally below their baseline visual acuity (0.8 letter loss), while Group I presented +2.1 letters gain. The number of injections given and the retention rate of the older cohort were no different to the rest of the patients. Very old patients with nAMD benefited from aflibercept, but not to the same degree as the younger patients. The study showed that, on an average, the very elderly patients were able to adhere to the intensive anti-VEGF treatment regimens.

Level-2 perspectives computed quickly and spontaneously: Evidence from eight- to 9.5-year-old children.

It has been widely assumed that computing how a scene looks from another perspective (level-2 perspective taking, PT) is an effortful process, as opposed to the automatic capacity of tracking visual access to objects (level-1 PT). Recently, adults have been found to compute both forms of visual perspectives in a quick but context-sensitive way, indicating that the two functions share more features than previously assumed. However, the developmental literature still shows the dissociation between automatic level-1 and effortful level-2 PT. In the current paper, we report an experiment showing that in a minimally social situation, participating in a number verification task with an adult confederate, eight- to 9.5-year-old children demonstrate similar online level-2 PT capacities as adults. Future studies need to address whether online PT shows selectivity in children as well and develop paradigms that are adequate to test preschoolers' online level-2 PT abilities. Statement of Contribution What is already known on this subject? Adults can access how objects appear to others (level-2 perspective) spontaneously and online Online level-1, but not level-2 perspective taking (PT) has been documented in school-aged children What the present study adds? Eight- to 9.5-year-olds performed a number verification task with a confederate who had the same task Children showed similar perspective interference as adults, indicating spontaneous level-2 PT Not only agent-object relations but also object appearances are computed online by eight- to 9.5-year-olds. © 2017 The British Psychological Society.

BACKGROUND/OBJECTIVES Dietary sugar intake, particularly added sugar and sugar-sweetened beverages, has received worldwide attention recently. Investigation of dietary behaviors may facilitate understanding of dietary sugar intakes of children and adolescents. However, the relationship between dietary sugar intake and dietary behaviors in the Korean population has not been investigated. Thus, this study aimed to estimate dietary sugar intake and food sources according to sex as well as examine the relationship of dietary sugar intake with frequent snacking and dietary patterns among Korean children and adolescents. SUBJECTS/METHODS We pooled data from five studies involving Korean children and adolescents conducted from 2002 to 2011. A total of 2,599 subjects aged 9-14 years were included in this study. Each subject completed more than 3 days of dietary records. RESULTS Mean daily total sugar intake was 46.6 g for boys and 54.3 g for girls. Compared with boys, girls showed higher sugar intakes from fruits (7.5 g for boys and 8.8 g for girls; P = 0.0081) and processed foods (27.9 g for boys and 34.9 g for girls; P < 0.0001). On average, 95.4% of boys and 98.8% of girls consumed snacks during the study period, and total sugar intake showed a significantly increasing trend with increasing energy intake from snacks (P < 0.0001 for both sexes). Two dietary patterns were identified by cluster analysis: Traditional and Westernized patterns. Total sugar intake was higher in the Westernized pattern (56.2 g for boys and 57.2 g for girls) than in the Traditional pattern (46.5 g for boys and 46.3 g for girls). CONCLUSIONS These results suggest that multilateral and practical development of a nutrition education and intervention program that considers dietary behaviors as well as absolute sugar intake is required to prevent excessive sugar intake in Korean children and adolescents.

In-utero exposure to endocrine-disrupting compounds, including dichlorodiphenyltrichloroethane (DDT) and its metabolite dichlorodiphenylethylene (DDE), has been hypothesized to increase the risk of obesity later in life. We examined the associations of maternal serum concentrations of DDT and DDE during pregnancy with body mass index, obesity, waist circumference, and percentage of body fat in 9-year-old children (n = 261) in the Center for the Health Assessment of Mothers and Children of Salinas (CHAMACOS) Study, a longitudinal birth cohort study in the Salinas Valley, California (2000–2010). We found associations between prenatal exposure to DDT and DDE and several measures of obesity at 9 years of age in boys but not in girls. For example, among boys, 10-fold increases in prenatal DDT and DDE concentrations were associated with increased odds of becoming overweight or obese (for o,p′-DDT, adjusted odds ratio (OR) = 2.5, 95% confidence interval (CI): 1.0, 6.3; for p,p′-DDT, adjusted OR = 2.1, 95% CI: 1.0, 4.5; and for p,p′-DDE, adjusted OR = 1.97, 95% CI: 0.94, 4.13). The odds ratios for girls were nonsignificant. Results were similar for body mass index z score, waist circumference z score, and odds of increased waist circumference but were less consistent for percentage of body fat. The difference by sex persisted after considering pubertal status. These results provide support for the chemical obesogen hypothesis. PMID:24722999

To assess the level of HPV knowledge among low income, minority mothers with a child between the ages of 9-17 y. Women who sought care at a university-based clinic and had at least 1 child aged 9 to 17 years were approached. A total of 638 mothers were recruited. Only those who had heard of HPV were included in the correlation analyses (n = 468). HPV knowledge was assessed utilizing a self-administered questionnaire consisting of 20 questions. There were differences between those who had heard of HPV and those who had not. More of those who had not heard of HPV were Hispanic (63%), low-income (89%), and did not graduate high school (59%). Of those who had heard of HPV, the majority did not answer 50% of questions correctly. Few knew the vaccine could prevent genital warts (19.7%). Factors independently associated with HPV knowledge included age, personal history of HPV, cervical dysplasia or cervical cancer, acquiring knowledge from ≥ 2 sources, having known someone with HPV or cervical cancer, having seen a brochure on the vaccine, and having seen an advertisement for the vaccine. Knowledge regarding HPV is low among low-income women with children in the target age range for HPV vaccination. Increased awareness should focus on genital warts and other cancers, since this population has virtually no knowledge of other health outcomes related to HPV infection. Educational programs tailored to this population need to be developed to increase vaccination. Copyright © 2015 North American Society for Pediatric and Adolescent Gynecology.

Pertussis vaccination with 4-5 doses of acellular vaccines is recommended in Spain to all children at 2 months to 6 years of age. The effectiveness of the acellular pertussis vaccination was assessed in this study by comparing the incidence of secondary pertussis in vaccinated (4-5 doses) and unvaccinated or partially vaccinated (0-3 doses) household contacts 1-9 years old of confirmed cases of pertussis in Spain in 2012-13. Eighty-five percent of contacts had been vaccinated with 4-5 doses of acellular pertussis vaccines. During the 2-year study period, 64 cases of secondary pertussis were detected among 405 household contacts 1-9 years old: 47 among vaccinated and 17 among unvaccinated or partially vaccinated contacts. The effectiveness for preventing secondary pertussis, calculated as 1 minus the relative risk (RR) of secondary pertussis in vaccinated vs. unvaccinated/partially vaccinated contacts, was 50 % [95 % confidence interval (CI): 19-69 %, p < 0.01] when household contacts were vaccinated using DTaP, Tdap, hexavalent or heptavalent vaccines, and it was 51.3 % (95 % CI: 21-70 %, p < 0.01) when they were vaccinated using DTaP or TdaP vaccines. The effectiveness adjusted for age, sex, pertussis chemotherapy and type of household contact was 58.6 % (95 % CI: 17-79 %, p < 0.05) when contacts were vaccinated using available acellular vaccines, and it was 59.6 % (95 % CI: 18-80 %, p < 0.01) when they were vaccinated using DTaP vaccines. Acellular pertussis vaccination during childhood was effective for preventing secondary pertussis in household contacts 1-9 years old of pertussis cases in Catalonia and Navarra, Spain.

Objective: To evaluate the accuracy of simple anthropometric parameters in diagnosing obesity in children in Guangzhou. Methods: A cross-sectional study, including 465 children aged 6-9 years, was carried out in Guangzhou. Their body height and weight, waist circumference (WC) and hip circumference were measured according to standard procedure. Body mass index (BMI), waist to hip ratio (WHR) and waist-to-height ratio (WHtR) were calculated. Body fat percentage (BF%) was determined by dual-energy X-ray absorptiometry. Multiple regression analysis was applied to evaluate the correlations between age-adjusted physical indicators and BF%, after the adjustment for age. Obesity was defined by BF%. Receiver operating characteristic (ROC) curve analyses were performed to assess the diagnostic accuracy of the indicators for childhood obesity. Area under-ROC curves (AUCs) were calculated and the best cut-off point that maximizing 'sensitivity + specificity-1' was determined. Results: BMI showed the strongest association with BF% through multiple regression analysis. For 'per-standard deviation increase' of BMI, BF% increased by 5.3% ( t =23.1, P <0.01) in boys and 4.6% ( t =17.5, P <0.01) in girls, respectively. The ROC curve analysis indicated that BMI exhibited the largest AUC in both boys (AUC=0.908) and girls (AUC=0.895). The sensitivity was 80.8% in boys and 81.8% in girls, and the specificity was 88.2% in boys and 87.1% in girls. Both the AUCs for WHtR and WC were less than 0.8 in boys and girls. WHR had the smallest AUCs (<0.8) in both boys and girls. Conclusion: BMI appeared to be a good predicator for BF% in children aged 6-9 years in Guangzhou.

QuickStats: Percentage* of Adults Aged ≥18 Years Who Cannot or Find It Very Difficult to Stand or Be on Their Feet for About 2 Hours Without Using Special Equipment,† by Age Group and Sex - National Health Interview Survey,§ United States, 2015.

2016-12-02

A reported 10.2% of adults aged ≥18 years cannot, or find it very difficult to, stand or be on their feet for about 2 hours without using special equipment. The percentage of adults who reported this difficulty increased with age: 2.9% of those aged 18-44 years, 11.8% of those aged 45-64 years, 19.1% of those 65-74 years, and 33.2% of those aged ≥75 years. Overall, women were more likely (11.9%) than men (8.3%) to report this difficulty, and higher percentages were noted for women within each age group.

There is a limited understanding about the relative importance of perceived and actual competence on emergent physical activity levels in children and whether there is a difference in their development and strength between boys and girls. This study used a single-cohort, multiple age group design to monitor physical activity, actual motor competence (AMC) and perceived competence (PC) on four occasions over 18 months in 6-to 9-year-old boys and girls (N = 201). Physical activity was measured by 7-day daily step counts (pedometer) and activity diary. AMC was assessed by mastery of skill criteria for 4 motor skills; run, overhand throw, standing broad jump, and line walk. PC was measured with the Self Description Questionnaire-I. Linear Mixed Model analysis revealed that AMC, Gender and School significantly impacted physical activity levels longitudinally in these children. AMC made a greater contribution (9-30%) to physical activity levels than PC (0-5%), and at an earlier age in boys (7 years) than girls (9 years). The need to acknowledge these developing distinctions in considering emergent physical activity levels has important implications for childhood learning environments and physical activity interventions.

As the intrauterine environment can effect children's growth and development, this study aimed to explore the relationship between birth high-risk and physique situation of 9 to 15-year-old children by cross-sectional investigation, and to provide clues for the monitoring, prevention, and treatment of growth deviation in children. This study recruited 7,194 students aged 9 to 15 years in primary and junior schools. Their parents were asked to complete the birth situation questionnaire. Measurements included height, weight, and body mass index (BMI). Birth high-risk infant was defined according to the gestational age and birth weight. Growth deviation was classified as underweight, short stature, overweight, and obesity. The prevalence of all kinds of growth deviations in preterm, full-term, and post-term birth groups were similar, the same as the physique situation at school age among both sexes. The incidence of small for gestational age (SGA) was 6.23%, when at school age, part of SGA had catch-up growth. However, the prevalence of underweight and short stature for SGA was highest in three groups. The weight and height at school age in SGA group was less than that in appropriate for gestational age (AGA) and large for gestational age (LGA) groups. The prevalence of overweight and obesity for LGA and macrosomia were highest in three groups. At school age, the weight in macrosomia and LGA groups was higher than that in the other groups. Longitudinal height and weight development and growth of children with birth high-risk are different from normal children. In order to improve healthy situation, more attention should be paid to height and weight development of those children with birth high-risk at school age, even in pre-school age. Prevention may already begin during pregnancy.

There is little information regarding age-related reference intervals (RIs) of carotid-femoral pulse wave velocity (cfPWV) for large healthy populations in South America. The aims of this study were to determine cfPWV RIs and percentiles in a cohort of healthy children, adolescents, and adults and to generate year-to-year percentile curves and body-height percentile curves for children and adolescents. cfPWV was measured in 1722 healthy participants with no cardiovascular risk factors (9-87 years, 60% men). First, RIs were evaluated for males and females through correlation and covariate analysis. Then, mean and standard deviation age-related equations were obtained for cfPWV using parametric regression methods based on fractional polynomials and age-specific (year-to-year) percentile curves that were defined using the standard normal distribution. Age-specific first, 2.5th, 5th, 10th, 25th, 50th, 75th, 90th, 95th, 97.5th, and 99th percentile curves were calculated. Finally, height-related cfPWV percentile curves for children and adolescents (<21 years) were established. After adjusting for age and blood pressure differences with respect to females, males showed higher cfPWV levels (6.60 vs 6.45 m/s; P < .01). Thus, specific RIs for males and females were reported. The study provides the largest database to date concerning cfPWV in healthy people from Argentina. Specific RIs and percentiles of cfPWV are now available according to age and sex. Specific percentiles of cfPWV according to body height were reported for people younger than 21 years. ©2018 Wiley Periodicals, Inc.

To report successful therapy for anisometropic and strabismic amblyopia initiated after age 7 years. A consecutive series of 36 compliant children older than 7 years (range, 7.0 to 10.3 years; mean, 8.2 years) at initiation of amblyopia therapy for anisometropic (19 patients; mean age, 8.3 years), strabismic (9 patients; mean age, 8.0 years), or anisometropic and strabismic (8 patients; mean age, 8.0 years) amblyopia was studied. Initial (worst) visual acuities were between 20/50 and 20/400 (log geometric mean, -0.83 [antilog, 20/134] for all patients; -0.88 [antilog, 20/151] for anisometropic patients; -0.70 [antilog, 20/100] for strabismic patients; and -0.88 [antilog, 20/151] for anisometropic and strabismic patients). Initial (worst) binocularity was absent or reduced in all cases. Therapy consisted of (1) full-time standard occlusion (21 patients; mean age, 8.0 years), (2) total penalization (7 patients; mean age, 7.8 years), or (3) full-time occlusive contact lenses (8 patients; mean age, 8.8 years). Final (best) visual acuities were between 20/20 and 20/30 for all 36 patients. Final (best) binocularity was maintained or improved for 22 (61%) of 36 patients, including 16 anisometropic patients (84%), 2 strabismic patients (22%), and 4 anisometropic and strabismic patients (50%). Given compliance, therapy for anisometropic and strabismic amblyopia can be successful even if initiated after age 7 years. Arch Ophthalmol. 2000;118:1535-1541

Objectives To identify ages when adolescents were in sexual maturity stages 2 through 5; to explain the relations between breast (girls), genital (boys), and pubic hair (girls and boys) development between ages 9½ and 15½ years; and to evaluate synchrony of pubertal development across characteristics. Design Annual pubertal assessments. Setting Ten locations in the United States. Participants A total of 859 adolescents (427 boys [49.7%] and 432 girls [50.3%]; 737 white [85.8%] and 122 black [14.2%]). Main Outcome Measures Changes in the 5 stages of breast, genital, and pubic hair development. Results Girls were in breast maturity stages 2 and 3 earlier than comparable pubic hair stages. Although breast development in girls started earlier than pubic hair development, girls completed breast and pubic hair development at approximately the same age. Black girls were in all stages of breast and pubic hair development earlier than white girls. Boys were in stages 2, 3, 4, and 5 of genital development before the comparable pubic hair stage. In boys, genital development started earlier than pubic hair development, but pubic hair development was completed in less time. Black boys were in genital and pubic hair development about 7 months earlier than white boys. Black and white boys completed genital development in approximately 4½ years, but black boys took approximately 6 months longer than white boys to complete pubic hair development. At stage 2, for 66.2% of girls, breast development preceded their pubic hair development; for 91.1% of boys, genital development preceded their pubic hair development. Conclusions The results of this study are useful in understanding normative variation in the timing and change in the development of secondary sexual characteristics at puberty. They will help identify adolescents with atypical changes in sexual maturation and unusual progression of sexual maturation and growth disorders. PMID:20124146

The genetic and environmental etiology of individual differences was examined in initial level and change in psychopathic personality from ages 9 to 18 years. A piecewise growth curve model, in which the first change score (G1) influenced all ages (9-10, 11-13, 14-15, and 16-18 years) and the second change score (G2) only influenced ages 14-15 and 16-18 years, fit the data better did than the standard single slope model, suggesting a turning point from childhood to adolescence. The results indicated that variations in levels and both change scores were mainly due to genetic (A) and nonshared environmental (E) influences (i.e., AE structure for G0, G1, and G2). No sex differences were found except on the mean values of level and change scores. Based on caregiver ratings, about 81% of variance in G0, 89% of variance in G1, and 94% of variance in G2 were explained by genetic factors, whereas for youth self-reports, these three proportions were 94%, 71%, and 66%, respectively. The larger contribution of genetic variance and covariance in caregiver ratings than in youth self-reports may suggest that caregivers considered the changes in their children to be more similar as compared to how the children viewed themselves.

To analyse the maternal identification of different stages of dental caries in children aged 1-3 years. A cross-sectional study was conducted with 274 children and their mothers. The mothers answered a questionnaire on the occurrence of dental caries in their children and completed questions addressing their demographic/socio-economic status. The oral examination of the children was performed using the International Caries Detection and Assessment System. Descriptive, Chi square test and Poisson regression statistical analyses were performed. The prevalence of initial and established/severe dental caries lesions by age were: 1 year (23.2 and 24.2%), 2 years (17.9 and 55.7%) and 3 years (23.3 and 60.3%) respectively. Significant associations between clinical examinations and the mothers' reports were observed among children aged 1 year old who had initial stage caries lesions (p = 0.006) and in children aged 1, 2 and 3 years old who had established/severe stage caries lesions (p < 0.001). After adjustment for confounding variables it was found that mothers were more able to identify dental caries both at initial (PR 4.01, 95% CI 1.35-11.94) and established/severe stages (PR 9.14, 95% CI 2.49-33.56) in children aged 1 year old. In children aged 2 and 3 years, this identification was more evident in the established/severe stage (2 years, PR 2.98, 95% CI 1.42-6.26; 3 years, PR 2.75, 95% CI 1.09-6.93). Mothers of children aged 1 year old identified dental caries at initial and established/severe stages. Mothers of children aged 2 and 3 years identified dental caries only at established/severe stages.

The present study investigated the relationship between age and one type of environmental factor, namely, type of school (i.e., private vs. public), and the development of mental planning ability, as measured by the Tower of London (TOL) test. Methods Participants comprised 197 public and 174 private school students, ranging in age from 4 years and 9 months to 8 years and 6 months. Besides the TOL test, students were administered Raven's Colored Matrices. Results Results confirmed the findings of previous studies that both age and school type are important predictors of mental planning. Furthermore, results also suggest that the relationship between type of school and mental planning ability cannot be accounted for by differences in students' fluid intelligence. Conclusion In the present study, the TOL test continued to differentiate public from private school students, even after we controlled for the effect of differences on the Raven test. PMID:29213536

Very preterm (VPT) children, with a birth weight below 1500 g or delivered before 32 weeks of gestational age, are at increased risk of poorer long-term health outcomes and higher rates of hospitalization in childhood. However, considerable variation exists in the need for in-hospital care within this population. We assessed the utilization and distribution of hospital-based care from ages 1 through 9 years for a nationwide population. This was a population-based cohort of VPT children born in the period 2001-2009. We evaluated their utilization of hospital care in 2008-2010, when aged 1-9 years old. Outcomes were the incidence of hospital admissions and outpatient visits. We used Poisson regression models with multiple imputation of missing data. Children born VPT had more hospital admissions compared with the general population of children aged 1-9 years. The rates of hospital admissions and outpatient visits were strongly related to clinical characteristics of the child at birth and age at admission/outpatient visit but to only a variable and minor degree to characteristics pertaining to maternal health, the sociodemographic factors, and geographical proximity to hospital services. Prior to this study, hospital utilization during the period 5-9 years old has been poorly documented. We found that excess utilization of hospital resources on average declines with increasing age. We also noted substantial differences in the use of hospital care across age groups and clinical factors for VPT children. The added information from the health status of mothers, social background, and geographic measures of access was limited.

Low levels of physical activity in childhood are associated with clustering of cardiovascular risk factors (CVRF) as predisposition for atherosclerosis. We assessed the association between sports engagement and age at first myocardial infarction (MI) in a cohort of men under 55 years of age. The Bern percutaneous coronary intervention Registry (NCT 02241291) was analyzed from March 2009 until January 2012. Male patients with first MI, age 18 to 54 years and body mass index ≤25kg/m2 were included. Patients were stratified into two groups based on their starting age with organized sports ≥1 h/week outside school (EARLY: <18, CONTROL: ≥18 years or never). We assessed age at time of first MI, CVRF, and volume of sports training. Of 4,394 consecutive patients, 123 fulfilled the inclusion criteria (EARLY n = 81, CONTROL n = 42). Age at the time of first MI was 3 years younger in the EARLY compared to the CONTROL group (46.8±6.0 vs. 49.8±4.6 years, p = 0.006). Total lifetime training hours, and average yearly training hours, both, before and after age 18, were significantly greater in the EARLY group. Years of training <18 years were weakly inversely correlated with age at first MI (r2 = 0.075, p = 0.002). The proportion of sports-related MI was not different between EARLY and CONTROL (13.6% vs. 11.9%). Patients in the EARLY group had fewer CVRF (2 vs. 3; p = 0.001). Prevalence of smoking was equally high in both groups (63.0% and 64.3%). In our patients aged 54 and younger, the first MI occurred 3 years earlier in those who started regular sports activity before age 18, despite a more active lifestyle and favorable CVRF profile.

Recently, an increasing number of patients with brain metastases, even patients over 80 years of age, have been treated with stereotactic radiosurgery (SRS). However, there is little information on SRS treatment results for patients with brain metastases 80 years of age and older. The authors undertook this study to reappraise whether SRS treatment results for patients 80 years of age or older differ from those of patients who are 65-79 years old. This was an institutional review board-approved, retrospective cohort study. Among 2552 consecutive brain metastasis patients who underwent SRS during the 1998-2011 period, we studied 165 who were 80 years of age or older (Group A) and 1181 who were age 65-79 years old (Group B). Because of the remarkable disproportion in patient numbers between the 2 groups and considerable differences in pre-SRS clinical factors, the authors conducted a case-matched study using the propensity score matching method. Ultimately, 330 patients (165 from each group, A and B) were selected. For time-to-event outcomes, the Kaplan-Meier method was used to estimate overall survival and competing risk analysis was used to estimate other study end points, as appropriate. Although the case-matched study showed that post-SRS median survival time (MST, months) was shorter in Group A patients (5.3 months, 95% CI 3.9-7.0 months) than in Group B patients (6.9 months, 95% CI 5.0-8.1 months), this difference was not statistically significant (HR 1.147, 95% CI 0.921-1.429, p = 0.22). Incidences of neurological death and deterioration were slightly lower in Group A than in Group B patients (6.3% vs 11.8% and 8.5% vs 13.9%), but these differences did not reach statistical significance (p = 0.11 and p = 0.16). Furthermore, competing risk analyses showed that the 2 groups did not differ significantly in cumulative incidence of local recurrence (HR 0.830, 95% CI 0.268-2.573, p = 0.75), rates of repeat SRS (HR 0.738, 95% CI 0.438-1.242, p = 0.25), or incidence

Our study aimed to evaluate the effect of various risk indicators for dental caries on primary teeth of Nicaraguan children (from Leon, Nicaragua) ages 6 to 9, using the negative binomial regression model. A cross-sectional study was carried out to collect clinical, demographic, socioeconomic, and behavioral data from 794 schoolchildren ages 6 to 9 years, randomly selected from 25 schools in the city of León, Nicaragua. Clinical examinations for dental caries (dmft index) were performed by 2 trained and standardized examiners. Socio-demographic, socioeconomic, and behavioral data were self-reported using questionnaires. Multivariate negative binomial regression (NBR) analysis was used. Mean age was 7.49 ± 1.12 years. Boys accounted for 50.1% of the sample. Mean dmft was 3.54 ± 3.13 and caries prevalence (dmft >0) was 77.6%. In the NBR multivariate model (p<0.05), for each year of age, the expected mean dmft decreased by 7.5%. Brushing teeth at least once a day and having received preventive dental care in the last year before data collection were associated with declines in the expected mean dmft by 19.5% and 69.6%, respectively. Presence of dental plaque increased the expected mean dmft by 395.5%. The proportion of students with caries in this sample was high. We found associations between dental caries in the primary dentition and dental plaque, brushing teeth at least once a day, and having received preventive dental care. To improve oral health, school programs and/or age-appropriate interventions need to be developed based on the specific profile of caries experience and the associated risk indicators.

Trachoma is the leading cause of preventable blindness worldwide. It is common in areas where people are socioeconomically deprived. Globally, approximately 1.2 billion people live in trachoma-endemic areas, in which, 40.6 million individuals have active trachoma and 8.2 million have trichiasis. According to the World Health Organization's 2007 report, globally close to 1.3 million people are blind due to trachoma, while approximately 84 million suffer from active trachoma. The National Survey (2007) of Ethiopia showed a prevalence of 40.1% active trachoma among children aged 1-9 years. Trachoma is still endemic in most parts of Ethiopia. To assess prevalence of trachoma and factors associated with it among children aged 1-9 years in Zala district, Gamo Gofa Zone, Southern Nations, Nationalities, and Peoples' Region. A community-based cross-sectional study was conducted in Zala district from February 28 to March 26, 2014. A total of 611 children were examined for trachoma based on the simplified World Health Organization 1983 classification. A multistage stratified sampling technique with a systematic random sampling technique was used to select study participants. Data were collected by using a semistructured pretested questionnaire and clinical eye examination. The data were entered using EpiData version 3.1 and analyzed using SPSS version 16. Multivariable logistic regression analysis was used to identify independently associated factors. The overall prevalence of active trachoma cases was 224 (36.7%) consisting of 207 (92.4%) trachomatous follicles, eight (3.6%) trachomatous intense, and nine (4.0%) combination of trachomatous follicle and trachomatous intense.

Quadrivalent live attenuated influenza vaccine (Q/LAIV) was licensed in 2012 and replaced trivalent live attenuated influenza vaccine in the United States during the 2013-2014 influenza season. This study assessed the safety of Q/LAIV in children and adults aged 2-49years. This was a prospective observational cohort study using data collected from Kaiser Permanente Northern California. Post-vaccination events of interest were any hospitalization, hospitalization for lower respiratory tract infection, and the following medically attended events: hypersensitivity, seizures/convulsions, lower respiratory tract infection, wheezing, Guillain-Barré syndrome, Bell's palsy, encephalitis, neuritis, vasculitis, and narcolepsy/cataplexy. The rates of these events during the risk interval post-vaccination were compared with rates observed during reference periods later in the follow-up (within-cohort analysis) and with rates observed in frequency-matched unvaccinated controls and inactivated influenza vaccine (IIV) recipients. A total of 62,040 eligible Q/LAIV recipients were identified during the 2013-2014 influenza season. Within-cohort comparisons of all Q/LAIV recipients as well as comparisons between Q/LAIV recipients and unvaccinated controls or IIV recipients did not show any significantly higher risk of hospitalizations or medically attended events following administration of Q/LAIV. Additional analyses by setting (clinic visits, emergency department visits, and hospital admissions) and age group (2-4, 5-8, 9-17, and 18-49years) also did not reveal clinically consistent findings that suggested any increased risk after administration of Q/LAIV. In this large population study of individuals aged 2-49years, no safety signals associated with the administration of Q/LAIV were observed. A much larger study population would be needed to confidently reject any association between Q/LAIV and very rare events, specifically those with an incidence of <1 event/10,000 person-years

A terrorist attack is an adverse event characterized by both an event-specific stressor and concern about future threats. Little is known about age differences in responses to terrorism. This longitudinal study examined generalized distress, posttraumatic stress responses, and fear of future attacks following the September 11, 2001 (9/11) terrorist attacks among a large U.S. national sample of adults (N = 2,240) aged 18-101 years. Individuals completed Web-based surveys up to 6 times over 3 years post 9/11. Multilevel models revealed different age-related patterns for distress, posttraumatic stress, and ongoing fear of future attacks. Specifically, older age was associated with lower overall levels of general distress, a steeper decline in posttraumatic stress over time, and less change in fear of future terrorist attacks over the 3 years. Understanding age differences in response to the stress of terrorism adds to the growing body of work on age differences in reactions to adversity.

The genetic and environmental etiology of individual differences was examined in initial level and change in psychopathic personality from ages 9 to 18 years. A piecewise growth curve model, in which the first change score (G1) influenced all ages (9–10, 11–13, 14–15, and 16–18 years) and the second change score (G2) only influenced ages 14–15 and 16–18 years, fit the data better did than the standard single slope model, suggesting a turning point from childhood to adolescence. The results indicated that variations in levels and both change scores were mainly due to genetic (A) and nonshared environmental (E) influences (i.e., AE structure for G0, G1, and G2). No sex differences were found except on the mean values of level and change scores. Based on caregiver ratings, about 81% of variance in G0, 89% of variance in G1, and 94% of variance in G2 were explained by genetic factors, whereas for youth self-reports, these three proportions were 94%, 71%, and 66%, respectively. The larger contribution of genetic variance and covariance in caregiver ratings than in youth self-reports may suggest that caregivers considered the changes in their children to be more similar as compared to how the children viewed themselves.

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.

The World Health Organization recommends administration of measles vaccine (MV) at age 9 months in low-income countries. We tested the measles virus antibody response at 4.5, 9, 18, and 24 months of age for children randomly assigned to receive standard-titer Edmonston-Zagreb MV at 4.5 and 9 months, at 9 months, or at 9 and 18 months of age. At 4.5 months of age, 75% had nonprotective measles virus antibody levels. Following receipt of MV at 4.5 months of age, 77% (316/408) had protective antibody levels at 9 months of age; after a second dose at 9 months of age, 97% (326/337) had protective levels at 24 months of age. In addition, the response at both 9 and 24 months of age was inversely correlated with the antibody level at receipt of the first dose of MV, and the second dose of MV, received at 9 months of age, provided a significant boost in antibody level to children who had low antibody levels. In the group of 318 children who received MV at 9 months of age, with or without a second dose at 18 months of age, 99% (314) had protective levels at 24 months of age. The geometric mean titer at 24 months of age was significantly lower in the group that received MV at 4.5 and 9 months of age than in the group that received MV at 9 months of age (P = .0001). In conclusion, an early 2-dose MV schedule was associated with protective measles virus antibody levels at 24 months of age in nearly all children.

Understanding risk factors that may vary culturally can help improve preventive strategies for obesity. This is the first cross-sectional study aimed to determine the risk factors for overweight/obesity in children aged 2-6 years in a central Anatolian city in Turkey. A total of 1582 children (1351 healthy, 231 overweight/obese) aged 2-6 years were included from the Anthropometry of Turkish Children aged 0-6 years database. Age, gender, birth weight, birth order, mother's age, mother's body mass index (BMI), weight gain of mothers during pregnancy, presence of gestational diabetes, breastfeeding duration, history of formula feeding, mother's and father's education, mother's job, monthly income, smoking at home and physical activity, sleep duration and duration of television (TV) watching of the children were evaluated as independent risk factors. Logistic regression analyses were performed to investigate risk factors for overweight/obesity. Having a high family income compared to bad [odds ratio (OR)=1.96; 95% confidence interval (CI): 1.237-3.106], increased the time of watching TV during the weekend (OR=1.094; 95% CI: 1.032-1.159), and similar physical activity level according to their peers compared to less (OR=2.957; 95% CI: 1.056-8.282) were found to be significantly associated with a higher risk of overweight/obesity in children aged 2-6 years old. The early childhood period seems to be important in the establishment of healthy behavioral patterns, especially limitation of TV watching and encouragement of physical activity. Obesogenic environment in families with high incomes need to be revealed.

Background Treatment decisions for older patients with type 2 diabetes mellitus must balance glycemic control and adverse event risk. The objective of this study was to evaluate the long-term safety and tolerability of saxagliptin 5 mg as add-on therapy to common antihyperglycemic drugs in patients aged ≥65 years and <65 years. Methods Pooled adverse event data from three placebo-controlled trials of 76–206 weeks’ duration in older (≥65 years) and younger (<65 years) patients receiving saxagliptin 5 mg or matching placebo added to metformin, glyburide, or a thiazolidinedione were analyzed. Measurements were calculated from day of first dose to specified event or last dose and included time at risk for adverse events, treatment-related adverse events, serious adverse events, adverse events leading to discontinuation, and events of special interest. Weighted incidence rates (number of events/total time) and incidence rate ratios (saxagliptin/placebo) with 95% confidence intervals were calculated (Mantel-Haenszel test). Results A total of 205 older (mean age 69 years; saxagliptin, n=99; placebo, n=106) and 1,055 younger (mean age 52 years; saxagliptin, n=531; placebo, n=524) patients were assessed. Regardless of age category, the adverse event incidence rates were generally similar between treatments, with confidence intervals for incidence rate ratios bridging 1. Treatment-related adverse events occurred in 36 older patients receiving saxagliptin versus 32 receiving placebo (incidence rate 34.1 versus 27.1 per 100 person-years) and in 150 younger patients in both treatment groups (incidence rate 24.0 versus 27.8 per 100 person-years). With saxagliptin versus placebo, serious adverse events occurred in eight versus 14 older (incidence rate 5.7 versus 9.9 per 100 person-years) and 49 versus 44 younger patients (incidence rate 6.5 versus 6.6 per 100 person-years). There were two deaths (one patient ≥65 years) with saxagliptin and six (none aged ≥65 years

The epidemiology of type 1 diabetes mellitus may provide insights into the pathogenesis of the disease. The aim of this work was to characterize the trend of the incidence of type 1 diabetes mellitus in Romanian children aged from 0 to 17 years over a 10-year interval. Data regarding new cases were obtained from two sources: (1) The Romanian Childhood Diabetes Registry and (2) Records of the Medical Center "Cristian Serban", Buzias. The demographic data were retrieved from the National Institute for Statistics. The incidence was calculated for the age groups 0-4, 5-9, 10-14, and 15-17 years. A total of 3196 new cases, aged below 18 years, were found by both the sources. There were significant differences between the groups (p=0.012), the mean incidence being highest in the age group 10-14 years (9.6/100,000/year, 95% CI 9-10.1) and lowest in children aged from 0 to 4 years (4.8/100,000/year, 95% CI 4.4-5.3). Boys were slightly more frequently affected than girls (p=0.038). The age and gender adjusted incidence of type 1 diabetes mellitus increased significantly (p<0.001) from 6.2/100,000/year (95% CI 5.5-6.9) in 2002 to 9.3/100,000/year (95% CI 8.4-10.3) in 2011. The raise in incidence was noticed in all age groups except for 15-17 years. Romania is a country with an intermediate incidence of type 1 diabetes mellitus in children, which is slightly higher in boys than in girls. The incidence of type 1 diabetes mellitus increased continuously during the 10-year survey, with the exception of the oldest teens.

In an era where around one in four children in the United Kingdom, the United States, and Australia are overweight or obese, the development of obesity in early life needs to be better understood. We aimed to identify groups of children with distinct trajectories of growth in infancy and early childhood, to examine any association between these trajectories and body size at age 9, and to assess the relative influence of antenatal and postnatal exposures on growth trajectories. Prospective Australian birth cohort study. In total, 557 children with serial height and weight measurements from birth to 9 years were included in the study. Latent class growth models were used to derive distinct groups of growth trajectories from birth to age 3½ years. Multivariable logistic regression models were used to explore antenatal and postnatal predictors of growth trajectory groups, and multivariable linear and logistic regression models were used to examine the relationships between growth trajectory groups and body size at age 9 years. We identified four discrete growth trajectories from birth to age 3½ years, characterised as low, intermediate, high, or accelerating growth. Relative to the intermediate growth group, the low group had reduced z-body mass index (BMI) (-0.75 s.d.; 95% confidence interval (CI) -1.02, -0.47), and the high and accelerating groups were associated with increased body size at age 9 years (high: z-BMI 0.70 s.d.; 95% CI 0.49, 0.62; accelerating: z-BMI 1.64 s.d.; 95% CI 1.16, 2.11). Of the antenatal and postnatal exposures considered, the most important differentiating factor was maternal obesity in early pregnancy, associated with a near quadrupling of risk of membership of the accelerating growth trajectory group compared with the intermediate growth group (odds ratio (OR) 3.72; 95% CI 1.15, 12.05). Efforts to prevent childhood obesity may need to be embedded within population-wide strategies that also pay attention to healthy weight for women in

Objective: The aim of the present study was to describe the intake of sugar-sweetened beverages and to examine of associated factors among schoolchildren from Bogotá, Colombia. Methods: From a total of 8,136 schoolchildren and adolescents (age 9-17.9 years) taking part in the FUPRECOL Study. Sugar-sweetened beverages intake was based on intake from “regular soda”, “drink tea” and/or “concentrated juices”. Body weigth, heigth, body mass index (BMI), waist circumference, and percentage body fat by electrical bioimpedance analysis were measured such as adiposity markers. Associated factors (sex, age, abdominal obesity, BMI classification, mothers’ and fathers’ educational level and nutritional status by “Krece plus” questionnaire), were collected by structured questionnaire. Associations were established through a binary logistic regression. Results: Of the subjects, 58.4% were women. According to sex, boys response highest intake of “regular soda” daily/weekly frequency of the 70.9% and 21.0%, respectively, followed by “concentrated juices” (64.4% weekly vs.11.3% daily). In both gender, the prevalence of abdominal obesity was higher in schoolchildren that responded to intake “regular soda” (23.3%), “concentrated juices” (13.2%) and “drink tea” daily (9.7%). Age [OR 1.15 (95%CI 1.03 to 1.28)], mothers’ [OR 1.30 (95%CI 1.03 to 1.65)], and fathers’ [OR 1.34 (95%CI 1.01 to 1.79) low educational level and nutritional status [OR 2.60 (95%CI 2.09 to 3.25)], were associated with daily intake of “regular soda”. Conclusion: Age, parental education level and dietary patterns were associated with sugar-sweetened beverages in schoolchildren in Bogotá, Colombia. We recommended comprehensive interventions which are involved nutritional and educational component among children and adolescents from Bogotá, Colombia.

Eating disorders pose risks to health and wellbeing in young adolescents, but prospective studies of risk factors are scarce and this has impeded prevention efforts. This longitudinal study aimed to examine risk factors for eating disorder symptoms in a population-based birth cohort of young adolescents at 12 years. Participants from the Gateshead Millennium Study birth cohort (n = 516; 262 girls and 254 boys) completed self-report questionnaire measures of eating disorder symptoms and putative risk factors at age 7 years, 9 years and 12 years, including dietary restraint, depressive symptoms and body dissatisfaction. Body mass index (BMI) was also measured at each age. Within-time correlates of eating disorder symptoms at 12 years of age were greater body dissatisfaction for both sexes and, for girls only, higher depressive symptoms. For both sexes, higher eating disorder symptoms at 9 years old significantly predicted higher eating disorder symptoms at 12 years old. Dietary restraint at 7 years old predicted boys' eating disorder symptoms at age 12, but not girls'. Factors that did not predict eating disorder symptoms at 12 years of age were BMI (any age), girls' dietary restraint at 7 years and body dissatisfaction at 7 and 9 years of age for both sexes. In this population-based study, different patterns of predictors and correlates of eating disorder symptoms were found for girls and boys. Body dissatisfaction, a purported risk factor for eating disorder symptoms in young adolescents, developed concurrently with eating disorder symptoms rather than preceding them. However, restraint at age 7 and eating disorder symptoms at age 9 years did predict 12-year eating disorder symptoms. Overall, our findings suggest that efforts to prevent disordered eating might beneficially focus on preadolescent populations. Copyright © 2016 The Authors. Published by Elsevier Ltd..

Background Our study aimed to evaluate the effect of various risk indicators for dental caries on primary teeth of Nicaraguan children (from Leon, Nicaragua) ages 6 to 9, using the negative binomial regression model. Material/Methods A cross-sectional study was carried out to collect clinical, demographic, socioeconomic, and behavioral data from 794 schoolchildren ages 6 to 9 years, randomly selected from 25 schools in the city of León, Nicaragua. Clinical examinations for dental caries (dmft index) were performed by 2 trained and standardized examiners. Socio-demographic, socioeconomic, and behavioral data were self-reported using questionnaires. Multivariate negative binomial regression (NBR) analysis was used. Results Mean age was 7.49±1.12 years. Boys accounted for 50.1% of the sample. Mean dmft was 3.54±3.13 and caries prevalence (dmft >0) was 77.6%. In the NBR multivariate model (p<0.05), for each year of age, the expected mean dmft decreased by 7.5%. Brushing teeth at least once a day and having received preventive dental care in the last year before data collection were associated with declines in the expected mean dmft by 19.5% and 69.6%, respectively. Presence of dental plaque increased the expected mean dmft by 395.5%. Conclusions The proportion of students with caries in this sample was high. We found associations between dental caries in the primary dentition and dental plaque, brushing teeth at least once a day, and having received preventive dental care. To improve oral health, school programs and/or age-appropriate interventions need to be developed based on the specific profile of caries experience and the associated risk indicators. PMID:24247119

The aim of this study was to analyze sexual behaviors and attitudes of children 9-14 years old in Spain. In this article we present data from 470 children of which 52% are boys and 48% girls. In order to evaluate the sample, Information, Attitudes and Behaviors related to Health Questionnaire (CIACS-II) was used. Results evidence that boys 9 years old already show behaviors that evidence their interest towards sexuality. 8% have sometimes masturbated and 9% have used pornography for becoming excited. 14% of children 11-12 years old have already had sexual relations and 38% state to have sexual fantasies. Girls start to masturbate and to have sexual relations later than boys and show a prevalence of sexual fantasies and use of pornography very lower. It is necessary sexual education programs to be implanted since early ages in schools.

Objective Our aim was to determine the effects of fetal exposure to propoxur and pyrethroids, on child neurodevelopment at 2 years of age. Patients and Methods Mothers were prospectively recruited during mid-pregnancy in Bulacan, Philippines where multiple pesticides including propoxur, cyfluthrin, chlorpyrifos, cypermethrin, pretilachlor, bioallethrin, malathion, diazinon and transfluthrin are used. To detect prenatal exposure to these pesticides, maternal hair and blood, infant’s hair, cord blood, and meconium were analyzed for the pesticides by gas chromatography/mass spectrometry. Infants were examined at 2 years of age with 95.1% follow up rate and their neurodevelopment outcome was assessed by the Griffiths Mental Developmental Scale (N=754). Results Meconium analysis was the most sensitive method to detect fetal exposure to pesticides and exposure was highest for propoxur (21.3%) and the grouped pyrethroids (2.5% - bioallethrin, transfluthrin, cyfluthrin and cypermethrin). Path analysis modeling was performed to determine the effects of fetal exposure to propoxur and pyrethroids on the child’s neurodevelopment at 24 months of age while controlling for confounders. Only singletons and those with complete data for the path analysis were included (N=696). Using a path analysis model, there was a significant negative (β= −0.14, p<0.001) relationship between prenatal pesticide exposure to propoxur and motor development at 2 years of age after controlling for confounders, e.g., infant gender, socioeconomic status, maternal intelligence, home stimulation (HOME), postnatal exposure to propoxur and blood lead level at 2 years of age. Conclusion At 2 years of age, prenatal exposure to propoxur was associated with poorer motor development in children. PMID:22155319

In the context of reduced transmission of malaria, it is essential to examine the association between exposure to malaria and haemoglobin level. This study measured the Haemoglobin level of children 2-9 years of age and examined its association with malariometric indices. A cross sectional study was conducted, during June 2016, on 763 children 2-9 years old, recruited from ten sites representing different malaria transmission settings in Ethiopia. Haemoglobin concentration was determined using HemoCue analyzer. Malariometric indices (splenomegaly rate, parasite rate and serological marker) were measured. The overall prevalence of anaemia was 17.3% (95% CI: 14.6-19.9) in the study population. Mild, moderate and severe anaemia accounted for 7.3%, 7.2% and 2.8% respectively. Of the children with anaemia (132), only 7 (5.3%) had malaria parasitaemia. The prevalence of malaria parasitaemia was 3.6% (2/56), 9.1% (5/55) and 0.0% (0/21) among children with mild, moderate and severe anaemia, respectively. Malaria reactive antibody and anaemia co-occurred in 3.13% (21/672) of the samples. Seroprevalence and parasitaemia did not have significant association with anaemia (p>0.05). However, splenomegaly was significantly associated with increased risk of anaemia (AOR=14.93; p=0.001). Anaemia was significantly higher among children 2-4 years old (22.2%), and children living in households without any insecticide treated bed net (34.0%). The prevalence of anaemia was lower by 55.0% among children living in households with at least one net (AOR=0.45, 95% CI: 0.21-0.96). Repeated exposure to malaria infections (seropositive) and parasitaemia was less likely to contribute to development of anaemia among children 2-9 years in this study setting. Thus, in low malaria endemic settings, anaemia prevention and control program required to reconsider the historical evidence that suggests malaria is one of the major risk factor for anaemia.

To identify ages when adolescents were in sexual maturity stages 2 through 5; to explain the relations between breast (girls), genital (boys), and pubic hair (girls and boys) development between ages 9(1/2) and 15(1/2) years; and to evaluate synchrony of pubertal development across characteristics. Annual pubertal assessments. Ten locations in the United States. A total of 859 adolescents (427 boys [49.7%] and 432 girls [50.3%]; 737 white [85.8%] and 122 black [14.2%]). Changes in the 5 stages of breast, genital, and pubic hair development. Girls were in breast maturity stages 2 and 3 earlier than comparable pubic hair stages. Although breast development in girls started earlier than pubic hair development, girls completed breast and pubic hair development at approximately the same age. Black girls were in all stages of breast and pubic hair development earlier than white girls. Boys were in stages 2, 3, 4, and 5 of genital development before the comparable pubic hair stage. In boys, genital development started earlier than pubic hair development, but pubic hair development was completed in less time. Black boys were in genital and pubic hair development about 7 months earlier than white boys. Black and white boys completed genital development in approximately 4(1/2) years, but black boys took approximately 6 months longer than white boys to complete pubic hair development. At stage 2, for 66.2% of girls, breast development preceded their pubic hair development; for 91.1% of boys, genital development preceded their pubic hair development. The results of this study are useful in understanding normative variation in the timing and change in the development of secondary sexual characteristics at puberty. They will help identify adolescents with atypical changes in sexual maturation and unusual progression of sexual maturation and growth disorders.

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

The aim of this study was to examine the association between maternal gestational diabetes mellitus (GDM) and childhood obesity at age 9-11 years in 12 countries around the world. A multinational cross-sectional study of 4740 children aged 9-11 years was conducted. Maternal GDM was diagnosed according to the ADA or WHO criteria. Height and waist circumference were measured using standardised methods. Weight and body fat were measured using a portable Tanita SC-240 Body Composition Analyzer. Multilevel modelling was used to account for the nested nature of the data. The prevalence of reported maternal GDM was 4.3%. The overall prevalence of childhood obesity, central obesity and high body fat were 12.3%, 9.9% and 8.1%, respectively. The multivariable-adjusted (maternal age at delivery, education, infant feeding mode, gestational age, number of younger siblings, child unhealthy diet pattern scores, moderate-to-vigorous physical activity, sleeping time, sedentary time, sex and birthweight) odds ratios among children of GDM mothers compared with children of non-GDM mothers were 1.53 (95% CI 1.03, 2.27) for obesity, 1.73 (95% CI 1.14, 2.62) for central obesity and 1.42 (95% CI 0.90, 2.26) for high body fat. The positive association was still statistically significant for central obesity after additional adjustment for current maternal BMI but was no longer significant for obesity and high body fat. Maternal GDM was associated with increased odds of childhood obesity at 9-11 years old but this association was not fully independent of maternal BMI.

Studies about changes in the prevalence of emotional and behaviour problems across time are lacking, especially among younger children. To determine if the level of parent-reported emotional and behaviour problems and competencies in young Norwegian school children had changed across a 16-year time interval. We compared parent reports obtained by the Child Behavior Checklist in two samples of children aged 7-9 years from the general population assessed in 1991 and 2007. The results demonstrated overall stability or slight decreases of emotional and behaviour problems and a significant increase in competencies, mainly due to increased activity and social competence scores in the 2007 sample. Boys obtained higher scores than girls in Total Problems, Externalizing and Attention problems at both time points and there was a high stability of the rank order of items. The findings suggest stability in child emotional and behaviour problems, and an increase of competencies across the period.

Data on visuomotor performance in combat training and the effects of combat training on visuomotor performance are limited. This study aimed to investigate the effects of a specially designed combat sports (CS) training program on the visuomotor performance levels of children. A pre-post comparative design was implemented. A total of 26 students aged 9-12 years underwent 40-min CS training sessions twice a week for 8 weeks during their physical education classes. The CS training program was designed by a karate coach and a motor control specialist. The other 30 students continued their regular activities and were considered as a control group. Each student's eye movement was monitored using an eye tracker, whereas the motor performance was measured using a target hitting system with a program-controlled microprocessor. The measurements were taken 8 weeks before (baseline), 1 day before (pretest), and 1 week after (posttest) the designated training program. The task used for evaluating these students was hitting or tracking random illuminated targets as rapidly as possible. A two-way analysis of variance [group(2) × time(3)] with repeated measures of time was performed for statistical analysis. For the children who received combat training, although the eye response improvement was not significant, both the primary and secondary saccade onset latencies were significantly earlier compared to the children without combat training. Both groups of students exhibited improvement in their hit response times during the target hitting tasks. The current finding supported the notion that sports training efforts essentially enhance visuomotor function in children aged 9-12 years, and combat training facilitates an earlier secondary saccade onset.

The reliability and construct validity of three age-adapted-intensity Yo-Yo tests were evaluated in untrained (n = 67) vs. soccer-trained (n = 65) 9- to 16-year-old schoolgirls. Tests were performed 7 days apart for reliability (9- to 11-year-old: Yo-Yo intermittent recovery level 1 children's test; 12- to 13-yearold: Yo-Yo intermittent endurance level 1; and 14- to 16-year-old: Yo-Yo intermittent endurance level 2). Yo-Yo distance covered was 40% (776 ± 324 vs. 556 ± 156 m), 85% (1252 ± 484 vs. 675 ± 252 m) and 138% (674 ± 336 vs. 283 ± 66 m) greater (p ≤ .010) for the soccer-trained than for the untrained girls aged 9-11, 12-13 and 14-16 years, respectively. Typical errors of measurement for Yo-Yo distance covered, expressed as a percentage of the coefficient of variation (confidence limits), were 10.1% (8.1-13.7%), 11.0% (8.6-15.4%) and 11.6% (9.2-16.1%) for soccer players, and 11.5% (9.1-15.8%), 14.1% (11.0-19.8%) and 10.6% (8.5-14.2%) for untrained girls, aged 9-11, 12-13 and 14-16, respectively. Intraclass correlation coefficient values for test-retest were excellent (0.795-0.973) in both groups. No significant differences were observed in relative exercise peak heart rate (%HRpeak) between groups during test and retest. The Yo-Yo tests are reliable for determining intermittent-exercise capacity and %HRpeak for soccer players and untrained 9- to 16-year-old girls. They also possess construct validity with better performances for soccer players compared with untrained age-matched girls, despite similar %HRpeak.

To determine decision limits for total cholesterol, LDL-cholesterol, non-HDL cholesterol, HDL-cholesterol, and triglycerides in healthy children and adolescents from Cuiabá, Brazil. This was a cross-sectional study of 1866 healthy children and adolescents randomly selected from daycare centers and public schools in Cuiabá. The desirable levels of serum lipids were defined using the classic criteria, i.e., total cholesterol, LDL-cholesterol, non-HDL cholesterol, and triglycerides levels below the P75 percentile, and HDL-c above the P10 percentile. For CT, P75 was: 160mg/dL for the age range of 1 to <3 years, 170mg/dL for ≥3 to <9 years, and 176mg/dL for ≥9 to <13 years. For non-HDL cholesterol, it was 122mg/dL for the age range of 1 to <13 years. For LDL-c, it was 104mg/dL at the age range of 1 to <9 years and 106mg/dL from ≥9 to <13 years. For TG, it was 127mg/dL from 1 to <2 years; 98mg/dL from ≥2 to <6 years; and 92mg/dL from ≥6 to <13 years. As for HDL-cholesterol, P10 was 24mg/dL, 28mg/dL, 32mg/dL, and 36mg/dL, for the age ranges of 1 to <2 years, ≥2 to <3 years, ≥3 to <4 years, and ≥4 to <13 years, respectively. The decision limits for the serum lipid levels defined in this study differed from those observed in the current Brazilian and North-American guidelines, especially because it differentiates between the age ranges. Using these decision limits in clinical practice will certainly contribute to improve the diagnostic accuracy for dyslipidemia in this population group.

Most of the published papers on Rheumatic Fever (RF) have not included the younger population. We selected 211 cases of children with RF younger than 6 years of age from 9,471 clinical files from 1944 to 1982. These were followed retrospectively to identify the presence of rheumatic activity, subsequent attacks and penicillin profilaxis. From de 211 cases, 209 had carditis; 57% of them were girls and 43% boys. There were no previous infections of the upper respiratory tract in 36% of the patients. The number of cases with RF increased abruptly after 3 years of age and continued increasing until 5 years of age when 70.5% of the population had there first clinically recognized attack. Lesions were present in the mitral valve in 80% of the cases, in the aortic valve in 12%, in the tricuspid in 5% and in the pulmonary valve in 3%. The death rate during the first attack was 20% being refractory heart failure the main cause of death. Thirteen cases suffered rheumatic pneumonia, 9 of whom died (69.2%). 1) The incidence of acute rheumatic fever in children under 6 years of age has decreased with time. 2) The death rate as well as the valvular damage decreased with the parents cooperation with the treatment. 3) The changes in the clinical picture and the severity of valve sequelea may be due to penicillin profilaxis and the better understanding of the disease.

Performance assessment has become an invaluable component of monitoring player development and within talent identification programs in soccer, yet limited performance data are available for female soccer players across a wide age range. The aim of this study was to describe the physical performance characteristics of female soccer players ranging in age from 12 to 21 years. High-level female soccer players (n=414) were evaluated on linear sprinting (36.6 m with 9.1 m splits), countermovement jump (CMJ), and two agility tests. Separate one-way ANOVAs were used to compare performance characteristics between (1) each year of chronological age and (2) three age groups: 12-13 years, n=78, 14-17 years, n=223, and 18-21 years, n=113. Mean linear sprint speed over 9.1 m was similar across all chronological ages, however sprint speed over the final 9.1 m, CMJ height and agility scores improved until approximately 15-16 years. Outcomes from the group data indicated better performance on all tests for the 14-17-year-old group compared with the 12-13-year-old group. Additionally, sprint speed on the second and fourth 9.1 m splits and 36.6 m sprint speed as well as performance on the Illinois agility test was better in the 18-21-year-old group compared with the 14-17-year-old group. The findings from this study indicate that marked improvements of high intensity short duration work occur up until 15-16 years. Smaller gains in performance were observed beyond 16 years of age as evidenced by better performance on 36.6 m sprint speed, several sprint splits and the Illinois agility test in the college aged players (i.e., 18-21-year-old group). © 2010 John Wiley & Sons A/S.

drugs acting on the central nervous system (CNS) increase falls risk. Most data on CNS drugs and falls are in women/mixed-sex populations. This study assessed the relationship between CNS drugs and falls in men aged 60-75 years. a questionnaire was sent to randomly selected Danish men aged 60-75 years. Cross-sectional data on CNS drugs and falls in the previous year were available for 4,696 men. Logistic regression investigated the relationship between falls and CNS drugs. the median age was 66.3 (IQR = 63.1-70.0) years; 21.7% were fallers. The following were associated with fallers (OR; 95% CI): opiates (2.4; 1.5-3.7), other analgesics (1.7; 1.4-2.1), antiepileptics (2.8; 1.5-5.1), antidepressants (2.8; 1.9-4.1) and anxiolytics/hypnotics (1.5; 0.9-2.6). Effects of opiates interacted strongly and significantly with age, with a marked association with falls in the older half of the subjects only. No significant associations were found between antipsychotics and fallers. Selective serotonin reuptake inhibitors and tricyclics were significantly associated with fallers (3.1; 2.0-5.0 and 2.2; 1.0-4.7, respectively). several CNS drug classes are associated with an approximately 2-3-fold increase risk of falls in men aged 60-75 years randomly selected from the population. Further longitudinal data are now required to confirm and further investigate the role of CNS drugs in falls causation in men.

This study aimed to assess the prevalence of diabetes and unrecognized diabetes in hypertensive patients aged 40 to 79 years in Southwest China. From September 2013 to March 2014, a cross-sectional survey was conducted in 4021 hypertensive patients aged 40 to 79 years living in Chengdu and Chongqing, China. Fasting plasma glucose (FPG) and 2h plasma glucose (2-hPG) in an oral glucose-tolerance test (OGTT) were used for assessments. Whether the patients previously had diabetes (DM) was determined by their own reports. The survey was carried out by the same questionnaire for all respondents. DM prevalence was 32.0% in hypertensive patients aged 40 to 79 years in Southwest China, with the rates of 29.6% and 33.5% in men and women, respectively (P<0.001). DM prevalence increased with age age and body-mass index. DM prevalence rates were 16.9%, 24.7%, 38.2% and 41.9% in hypertensive patients aged 40–49, 50–59, 60–69 and over 70, respectively. DM prevalence were 30.6%, 27.9%, 37.1%, and 37.4%, for BMI<18.5, 18.5–24.9, 25.0–29.9, and ≥30, respectively. Prevalence of unrecognized DM were 20.8% in hypertensive patients aged 40 to 79 years in Southwest China. Using only fasting blood glucose testing without OGTT would have resulted in 65.0% of missed DM diagnosis in these newly diagnosed patients. The prevalence of DM and unrecognized DM were high in hypertensive patients aged 40 to 79 years in Southwest China.These findings indicate that hypertensive patients aged 40 to 79 years should regularly submit to community-based OGTT screening for timely DM diagnosis.

The sequelae of increasing childhood obesity are of major concern. We assessed the association of BMI in late adolescence with diabetes mortality in midlife. The BMI values of 2,294,139 Israeli adolescents (age 17.4 ± 0.3 years), measured between 1967 and 2010, were grouped by U.S. Centers for Disease Control and Prevention age/sex percentiles and by ordinary BMI values. The outcome, obtained by linkage with official national records, was death attributed to diabetes mellitus (DM) as the underlying cause. Cox proportional hazards models were applied. During 42,297,007 person-years of follow-up (median, 18.4 years; range <1-44 years) there were 481 deaths from DM (mean age at death, 50.6 ± 6.6 years). There was a graded increase in DM mortality evident from the 25th to the 49th BMI percentile group onward and from a BMI of 20.0-22.4 kg/m 2 onward. Overweight (85th to 94th percentiles) and obesity (the 95th percentile or higher), compared with the 5th to 24th percentiles, were associated with hazard ratios (HRs) of 8.0 (95% CI 5.7-11.3) and 17.2 (11.9-24.8) for DM mortality, respectively, after adjusting for sex, age, birth year, height, and sociodemographic variables. The HR for the 50th through 74th percentiles was 1.6 (95% CI 1.1-2.3). Findings persisted in a series of sensitivity analyses. The estimated population-attributable fraction for DM mortality, 31.2% (95% CI 26.6-36.1%) for the 1967-1977 prevalence of overweight and obesity at age 17, rose to a projected 52.1% (95% CI 46.4-57.4%) for the 2012-2014 prevalence. Adolescent BMI, including values within the currently accepted "normal" range, strongly predicts DM mortality up to the seventh decade. The increasing prevalence of childhood and adolescent overweight and obesity points to a substantially increased future adult DM burden. © 2016 by the American Diabetes Association.

To document the prevalence of overweight, obesity and thinness in 9-10 year old children in Mauritius. 412 boys and 429 girls aged 9-10 years from 23 primary schools were selected using stratified cluster random sampling. All data was cross-sectional and collected via anthropometry and self-administered questionnaire. Outcome measures were BMI (kg/m2), prevalence of overweight, obesity (International Obesity Task Force definitions) and thinness (low BMI for age). Linear and logistic regression analyses, accounting for clustering at the school level, were used to assess associations between gender, ethnicity, school location, and school's academic performance (average) to each outcome measure. The distribution of BMI was marginally skewed with a more pronounced positive tail in the girls. Median BMI was 15.6 kg/m2 in boys and 15.4 kg/m2 in girls, respectively. In boys, prevalence of overweight was 15.8% (95% CI: 12.6, 19.6), prevalence of obesity 4.9% (95% CI: 3.2, 7.4) and prevalence of thinness 12.4% (95% CI: 9.5, 15.9). Among girls, 18.9% (95% CI: 15.5, 22.9) were overweight, 5.1% (95% CI: 3.4, 7.7) were obese and 13.1% (95% CI: 10.2, 16.6) were thin. Urban children had a slightly higher mean BMI than rural children (0.5 kg/m2, 95% CI: 0.01, 1.00) and were nearly twice as likely to be obese (6.7% vs. 4.0%; adjusted odds ratio 1.6; 95% CI: 0.9, 3.5). Creole children were less likely to be classified as thin compared to Indian children (adjusted odds ratio 0.3, 95% CI: 0.2, 0.6). Mauritius is currently in the midst of nutritional transition with both a high prevalence of overweight and thinness in children aged 9-10 years. The coexistence of children representing opposite sides of the energy balance equation presents a unique challenge for policy and interventions. Further exploration is needed to understand the specific causes of the double burden of malnutrition and to make appropriate policy recommendations.

In typically developing children, drawing development occurs in stages from uncontrolled strokes to complex drawing. In this study, we examined drawing development in children with neurodevelopmental delay (NDD). In order to do so, we observed the influence of age, intraventricular hemorrhage (IVH) and gender on the development of drawing skills. The sample consisted of 52 children with NDD, aged 2 years and 6 months to 5 years. All children were hospitalized for multidisciplinary team monitoring and developmental support. The evaluation of drawing development was administered by giving each child a blank A4 paper and the instruction to draw anything they wanted. All of the drawings were scored satisfactory or unsatisfactory. Descriptive statistics was employed on all relevant data to show results in frequencies and percentages. In order to determine differences between groups, the χ2-test was administered. The results showed greatest difference in drawing in children aged from 3 years to 3 years and 11 months. Children with lower IVH had better drawing scores than children with higher IVH levels. According to gender dissimilarities, a difference was found showing girls to have better drawing skills than boys. All study results pointed to the importance of early rehabilitation and continuous structured work with children with NDD.

Teens who give birth at age 15-17 years are at increased risk for adverse medical and social outcomes of teen pregnancy. To examine trends in the rate and proportion of births to teens aged 15-19 years that were to teens aged 15-17 years, CDC analyzed 1991-2012 National Vital Statistics System data. National Survey of Family Growth (NSFG) data from 2006-2010 were used to examine sexual experience, contraceptive use, and receipt of prevention opportunities among female teens aged 15-17 years. During 1991-2012, the rate of births per 1,000 teens declined from 17.9 to 5.4 for teens aged 15 years, 36.9 to 12.9 for those aged 16 years, and 60.6 to 23.7 for those aged 17 years. In 2012, the birth rate per 1,000 teens aged 15-17 years was higher for Hispanics (25.5), non-Hispanic blacks (21.9), and American Indians/Alaska Natives (17.0) compared with non-Hispanic whites (8.4) and Asians/Pacific Islanders (4.1). The rate also varied by state, ranging from 6.2 per 1,000 teens aged 15-17 years in New Hampshire to 29.0 in the District of Columbia. In 2012, there were 86,423 births to teens aged 15-17 years, accounting for 28% of all births to teens aged 15-19 years. This percentage declined from 36% in 1991 to 28% in 2012 (p<0.001). NSFG data for 2006-2010 indicate that although 91% of female teens aged 15-17 years received formal sex education on birth control or how to say no to sex, 24% had not spoken with parents about either topic; among sexually experienced female teens, 83% reported no formal sex education before first sex. Among currently sexually active female teens (those who had sex within 3 months of the survey) aged 15-17 years, 58% used clinical birth control services in the past 12 months, and 92% used contraception at last sex; however, only 1% used the most effective reversible contraceptive methods. Births to teens aged 15-17 years have declined but still account for approximately one quarter of births to teens aged 15-19 years. These data highlight

Because conducting population-based oral health screening is resource intensive, oral health data at small-area levels (e.g., county-level) are not commonly available. We applied the multilevel logistic regression and poststratification method to estimate county-level prevalence of untreated dental caries among children aged 6-9years in the United States using data from the National Health and Nutrition Examination Survey (NHANES) 2005-2010 linked with various area-level data at census tract, county and state levels. We validated model-based national estimates against direct estimates from NHANES. We also compared model-based estimates with direct estimates from select State Oral Health Surveys (SOHS) at state and county levels. The model with individual-level covariates only and the model with individual-, census tract- and county-level covariates explained 7.2% and 96.3% respectively of overall county-level variation in untreated caries. Model-based county-level prevalence estimates ranged from 4.9% to 65.2% with median of 22.1%. The model-based national estimate (19.9%) matched the NHANES direct estimate (19.8%). We found significantly positive correlations between model-based estimates for 8-year-olds and direct estimates from the third-grade State Oral Health Surveys (SOHS) at state level for 34 states (Pearson coefficient: 0.54, P=0.001) and SOHS estimates at county level for 53 New York counties (Pearson coefficient: 0.38, P=0.006). This methodology could be a useful tool to characterize county-level disparities in untreated dental caries among children aged 6-9years and complement oral health surveillance to inform public health programs especially when local-level data are not available although the lack of external validation due to data unavailability should be acknowledged.

We use ASAD2, the new version of ASAD (Analyzer of Spectra for Age Determination), to obtain the age and reddening of 27 Large Magellanic Cloud (LMC) clusters from full fitting of integrated spectra using different statistical methods [χ2 and Kolmogorov-Smirnov (KS) test] and a set of stellar population models including GALAXEV and MILES. We show that our results are in good agreement with the colour-magnitude diagram (CMD) ages for both models, and that metallicity does not affect the age determination for the full spectrum fitting method regardless of the model used for ages with log (age/year) < 9. We discuss the results obtained by the two statistical results for both GALAXEV and MILES versus three factors: age, signal-to-noise ratio and resolution (full width at half maximum). The predicted reddening values when using the χ2 minimization method are within the range found in the literature for resolved clusters (I.e. <0.35); however the KS test can predict E(B - V) higher values. The sharp spectrum transition originated at ages around the supergiants contribution, at either side of the AGB peak around log (age/year) 9.0 and log (age/year) 7.8 are limiting our ability to provide values in agreement with the CMD estimates and as a result the reddening determination is not accurate. We provide the detailed results of four clusters spanning a wide range of ages.

Seasonal influenza in healthy working-age adults accounts for a substantial part of the socioeconomic burden of this disease. Intanza® 9 μg (sanofi pasteur) is a microneedle-delivered intradermal trivalent inactivated influenza vaccine approved in 2009 for the prevention of seasonal influenza in adults 18 to 59 y of age. The microneedle system reliably and reproducibly delivers the vaccine to the dermis. Clinical studies show that Intanza 9 μg is as immunogenic and as well tolerated in working-age adults as a reference intramuscular trivalent inactivated vaccine. Local reactions to Intanza 9 μg, mainly erythema, are transient, mostly mild or moderate, and do not affect acceptability. Intanza 9 μg is considered satisfactory by at least 95% of both vaccinees and prescribers, especially because of the short needle and rapid administration. Because Intanza® 9 μg offers an alternative to intramuscular vaccines, it might help increase influenza vaccine coverage rates. PMID:23442585

The current study tested a set of interrelated theoretical propositions based on a dual-systems model of self-control. Data were collected from 2135 children aged 3 to 9 years. The results suggest that (a) there was positive growth in good self-control, whereas poor control remained relatively stable; and (b) girls performed better than boys on tests of good self-control. The results are discussed in terms of their implications for a dual-systems model of self-control theory and future empirical work. PMID:25501669

Morphine is widely used to treat severe pain in neonatal intensive care unit patients. Animal studies suggest adverse long-term side effects of neonatal morphine, but a follow-up study of 5-year-old children who participated in a morphine-placebo controlled trial as newborns found no such effects on the child's general functioning. This study indicated that morphine may negatively affect response inhibition, a domain of executive functions. Therefore, we performed a second follow-up study in the same population at the age of 8 to 9 years, focused on the child's general functioning in terms of intelligence, visual motor integration, and behavior and on executive functions. Children in the morphine group showed significantly less externalizing problems according to the parents but more internalizing behavior according to the teachers, but only after adjustment for intelligence quotient (IQ), potential confounders using a propensity score, and additional open-label morphine. Morphine-treated children showed significantly fewer problems with executive functions in daily life as rated by parents for the subscales inhibition and organization of materials and for planning/organizing as rated by the teachers. After adjustment for IQ and the propensity score, executive functioning as rated by the parents remained statistically significantly better in the morphine-treated group. The influence of the additional morphine given was not of a significant influence for any of the outcome variables. Overall, the present study demonstrates that continuous morphine infusion of 10 μg/kg/h during the neonatal period does not harm general functioning and may even have a positive influence on executive functions at 8 to 9 years.

Previous research investigating outcomes after pediatric intracerebral hemorrhage (ICH) has generally been limited to global and sensorimotor outcomes. This study examined cognitive outcomes after spontaneous ICH in school-aged children with serial assessments over 2 years after stroke. Seven children (age range 6-16y, median 13; six males, one female; 57% white, 43% black) presenting with spontaneous ICH (six arteriovenous malformations) were assessed at 3 months, 12 months, and 24 months after stroke. The Pediatric Stroke Outcome Measure (PSOM) quantified neurological outcome and Wechsler Intelligence Scales measured cognitive outcomes: verbal comprehension, perceptual reasoning, working memory, and processing speed. PSOM scales showed improved neurological function over the first 12 months, with mild to no sensorimotor deficits and moderate overall deficits at 1- and 2-year follow-ups (median 2-year sensorimotor PSOM=0.5, total PSOM=1.5). Changes in cognitive function indicated a different trajectory; verbal comprehension and perceptual reasoning improved over 24 months; low performance was sustained in processing speed and working memory. Age-normed centile scores decreased between 1- and 2-year follow-ups for working memory, suggesting emerging deficits compared with peers. Early and serial cognitive testing in children with ICH is needed to assess cognitive functioning and support children in school as they age and cognitive deficits become more apparent and important for function. In children with intracerebral hemorrhage (ICH), motor function improved between 3 months and 24 months. Improvements in cognitive function were variable between 3 months and 24 months. Working memory centiles declined, suggesting emerging deficits compared with peers. Processing speed improved but remained significantly below the 50th centile. Cognitive impact of ICH may increase with age in children. © 2017 Mac Keith Press.

Background Trachoma is the leading cause of preventable blindness worldwide. It is common in areas where people are socioeconomically deprived. Globally, approximately 1.2 billion people live in trachoma-endemic areas, in which, 40.6 million individuals have active trachoma and 8.2 million have trichiasis. According to the World Health Organization’s 2007 report, globally close to 1.3 million people are blind due to trachoma, while approximately 84 million suffer from active trachoma. The National Survey (2007) of Ethiopia showed a prevalence of 40.1% active trachoma among children aged 1–9 years. Trachoma is still endemic in most parts of Ethiopia. Objective To assess prevalence of trachoma and factors associated with it among children aged 1–9 years in Zala district, Gamo Gofa Zone, Southern Nations, Nationalities, and Peoples’ Region. Methods A community-based cross-sectional study was conducted in Zala district from February 28 to March 26, 2014. A total of 611 children were examined for trachoma based on the simplified World Health Organization 1983 classification. A multistage stratified sampling technique with a systematic random sampling technique was used to select study participants. Data were collected by using a semistructured pretested questionnaire and clinical eye examination. The data were entered using EpiData version 3.1 and analyzed using SPSS version 16. Multivariable logistic regression analysis was used to identify independently associated factors. Results The overall prevalence of active trachoma cases was 224 (36.7%) consisting of 207 (92.4%) trachomatous follicles, eight (3.6%) trachomatous intense, and nine (4.0%) combination of trachomatous follicle and trachomatous intense. Inadequate knowledge of family head about trachoma (adjusted odds ratio [AOR] =2.8 [95% CI: 1.9, 4.2]); ≤10 m latrine distance (AOR =1.6 [95% confidence interval {CI}: 1.09, 2.4]); presence of above two preschool children (AOR =2.2 [95% CI: 1.3, 3.7]), flies

ABSTRACT The introduction of pertussis vaccination in the United States (US) in the 1940s has greatly reduced its burden. However, the incidence of pertussis is difficult to quantify, as many cases are not laboratory-confirmed or reported, particularly in adults. This study estimated pertussis incidence in a commercially insured US population aged <50 years. Data were extracted from IMS' PharMetrics Plus claims database for patients with a diagnosis of pertussis or cough illness using International Classification of Diseases (ICD-9) codes, a commercial outpatient laboratory database for patients with a pertussis laboratory test, and the Centers for Disease Control influenza surveillance database. US national pertussis incidence was projected using 3 methods: (1) diagnosed pertussis, defined as a claim for pertussis (ICD-9 033.0, 033.9, 484.3) during 2008–2013; (2) based on proxy pertussis predictive logistic regression models; (3) using the fraction of cough illness (ICD-9 033.0, 033.9, 484.3, 786.2, 466.0, 466.1, 487.1) attributed to laboratory-confirmed pertussis, estimated by time series linear regression models. Method 1 gave a projected annual incidence of diagnosed pertussis of 9/100,000, which was highest in those aged <1 year. Method 2 gave an average annual projected incidence of 21/100,000. Method 3 gave an overall regression-estimated weighted annual incidence of pertussis of 649/100,000, approximately 58–93 times higher than method 1 depending on the year. These estimations, which are consistent with considerable underreporting of pertussis in people aged <50 years and provide further evidence that the majority of cases go undetected, especially with increasing age, may aid in the development of public health programs to reduce pertussis burden.

Obesity is increasing in developing countries. This study aimed to identify the association between rapid infancy weight gain and obesity risk among early school-age children. A total of 581 singletons (349 boys, 232 girls) whose mothers participated in an antenatal multiple micronutrient supplement trial in rural western China were followed from birth to between 7 and 9 years of age. Height and weight were measured at birth, 1.5 years, and between 7 and 9 years. At the 7- to 9-year time point, body composition was determined using bioelectrical impedance analysis. Multilevel mixed analysis was used to test the associations between rapid weight gain in infancy (from birth to age 1.5 years) and body size and composition or overweight/obesity among early school-age children. Overall, 31.2% (181 of 581) of the infants showed a weight-for-age Z score gain greater than 0.67 between birth and 1.5 years, indicating rapid weight gain. Approximately 5.7% (33 of 579) of the subjects were overweight (BMI-for-age Z scores [BAZ] >1 and ≤2) or obese (BAZ >2). Rapid infancy weight gain was associated with a higher BAZ (P < 0.001), mid-upper arm circumferences (P < 0.001), percentage body fat (P < 0.001), and fat mass index (P < 0.001) at 7 to 9 years of age after adjusting for biological and social economic factors, genetic factors, and perinatal and postnatal factors. These associations appeared to be independent of gender, economic status at early school age, and maternal nutritional status at enrollment. Rapid growers may have approximately 3 times the risk of being overweight/obese during the early school-age years (odds ratio = 2.94, 95% CI: 1.17-7.43, P = 0.022). Rapid infancy weight gain is a risk factor for being overweight/obesity among early school-age children in rural western China. We propose that social and biological determinants, such as economic status, physical activity, and feeding practice, should be targeted to prevent obesity.

In 1964, The Melbourne Asthma Study was established to describe the spectrum and natural history of childhood asthma. To describe the clinical and lung function outcome of childhood asthma to the age of 50 years. Subjects were invited to complete an interviewer-administered questionnaire, skin prick testing, and measurement of lung function from the age of 7 years to the age of 50 years at 7-year intervals. Of 458 survivors (from the original 484 subjects at recruitment), 346 subjects (76%) participated, of whom, 197 completed lung function measurement. Asthma remission at the age of 50 years was 64% in those with wheezy bronchitis, 47% for those with persistent asthma, and 15% for those with severe asthma in childhood. Multivariable analysis identified severe asthma in childhood (odds ratio [OR] 11.9 [95% CI, 3.4-41.8]), female sex (OR 2.0 [95% CI, 1.1-3.6]), and childhood hay fever (OR 2.0 [95% CI, 1.0-4.0]) as risk factors for "current asthma" at age 50 years. There was no evidence of a difference in the rate of decline in FEV1 (mL/y, 95% CI) between the severe asthma group (15 mL/y [95% CI, 9-22 mL/y]) and all the other recruitment groups: control (16 mL/y [95% CI, 12-20 mL/y]), mild wheezy bronchitis (14 mL/y [95% CI, 8-19 mL/y]), wheezy bronchitis (16 mL/y [95% CI, 11-20 mL/y]), and persistent asthma (19 mL/y [95% CI, 13-24 mL/y]). The clinical and lung function outcome in adult life is strongly determined by asthma severity in childhood. The reduced lung function seen in adults is established in childhood and does not appear to decline more rapidly in adult years despite continuing symptoms.

Moderate and late preterm (MLPT) births comprise most preterm infants. Therefore, long-term developmental concerns in this population potentially have a large public health influence. While there are increasing reports of developmental problems in MLPT children, detail is lacking on the precise domains that are affected. To compare neurodevelopment and social-emotional development between MLPT infants and term-born control infants at age 2 years. This investigation was a prospective longitudinal cohort study at a single tertiary hospital. Participants were MLPT infants (32-36 weeks' completed gestation) and healthy full-term controls (≥37 weeks' gestation) recruited at birth. During a 3-year period between December 7, 2009, and November 7, 2012, MLPT infants were recruited at birth from the neonatal unit and postnatal wards of the Royal Women's Hospital, Melbourne, Australia. The term control recruitment extended to March 26, 2014. The dates of the data developmental assessments were February 23, 2012, to April 8, 2016. Moderate and late preterm birth. Cerebral palsy, blindness, and deafness assessed by a pediatrician; cognitive, language, and motor development assessed using the Bayley Scales of Infant Development-Third Edition (developmental delay was defined as less than -1 SD relative to the mean in controls in any domain of the scales); and social-emotional and behavioral problems assessed by a parent questionnaire (Infant Toddler Social Emotional Assessment). Outcomes were compared between birth groups using linear and logistic regression, adjusted for social risk. In total, 198 MLPT infants (98.5% of 201 recruited) and 183 term-born controls (91.0% of 201 recruited) were assessed at 2 years' corrected age. Compared with controls, MLPT children had worse cognitive, language, and motor development at age 2 years, with adjusted composite score mean differences of -5.3 (95% CI, -8.2 to -2.4) for cognitive development, -11.4 (95% CI, -15.3 to -7.5) for language

Obesity is considered the second most common health problem in pet cats in developed countries. This study used prospective data from a longitudinal study of pet cats ('C.L.A.W.S.', www.bristol.ac.uk/vetscience/claws) to identify early-life risk factors for feline overweight/obesity occurring at around two years of age. Data were collected via five owner-completed questionnaires (for cats aged two-six months, six months, 12 months, 18 months and two years respectively) completed between May 2011 and April 2015. Owner-reported body condition scores (BCS) of cats at age two years, assessed using images from the 9-point BCS system (Laflamme, 1997), were categorised into a dichotomous variable: overweight/obese (BCS 6-9) and not overweight (BCS 1-5) and used as the dependent variable. Of the 375 cats with owner-reported BCS, 25.3% were overweight or obese at two years of age. Multivariable logistic regression models were built using stepwise forward-selection. To account for potential hierarchical clustering due to multi-cat households two-level random intercept models were considered but clustering had no impact on the analysis. Models were compared using Wald tests. Six factors were significantly associated with overweight/obesity at two years of age: being overweight or obese at one year of age (OR=10.6, 95%CI 4.4-25.3); owner belief that BCS 7 was the ideal weight (OR=33.2, 95%CI 8.5-129.4), or that BCS represented overweight cats but they would not be concerned if their cat were classified in this category (OR=2.7, 95%CI 1.2-6.2), at questionnaire five completion; vets advising owners that the cat should lose weight, or making no comment on their weight, between one and two years of age (OR=12.1, 95%CI 3.2-44.9 and OR=3.9, 95%CI 1.5-10.3 respectively); owners giving their cat treats when they "felt happy" with them at 18 months of age (OR=2.7, 95%CI 1.0 - 7.3); feeding ≥250g wet food daily between two and six months of age (OR=2.7, 95%CI 1.2-5.9), and feeding

To report complications and 2-year valve survival following Ahmed valve implantation during the first 2 years of life. Retrospective institutional case series. Forty-two eyes of 36 patients with Ahmed valve implantation (without prior drainage device surgery) during the first 2 years of life and 2 years' postsurgical follow-up were identified. Most eyes had primary congenital glaucoma (28/42, 66.7%), aphakic glaucoma (5/42, 11.9%) or Peters anomaly (5/42, 11.9%). All but three eyes had prior ocular surgery. Surgery was at a mean age of 11.83 months (m) (SD 5.63). The most common significant postoperative complications were tube malpositioning requiring intervention (11/42, 26.2%), endophthalmitis (3/42, 7.1%; one with tube exposure) and retinal detachment (3/42, 7.1%). Thirty-six eyes (85.8%) required resumption of antiglaucoma medications to maintain intraocular pressure (IOP) < or =22 mm Hg a mean of 7.2 m (SD 6.8) postoperatively. Cumulative probabilities of valve survival (IOP< or =22 mm Hg with or without medication) by Kaplan-Meier analysis were 73.8% and 63.3% at 12 months and 24 months, respectively. Postoperative tube malpositioning that required surgical revision was common in this age group. Infectious endophthalmitis and retinal detachment are known potential complications following any incisional surgery for advanced buphthalmos; however, tube exposure is a unique potential problem following aqueous shunt implantation that can lead to intraocular infection. Cumulative valve survival 2 years following implantation was 63.3%.

To examine the relative importance of antenatal and perinatal variables on short- and long-term outcome of preterm growth restricted fetuses with umbilical artery (UA) Doppler abnormalities. This was a cohort study of 180 neonates with birth weight < 10(th) percentile, gestational age at delivery < 34 weeks and abnormal Doppler ultrasound examination of the UA. Various antenatal and perinatal variables were studied in relation to short- and long-term outcome. Neonatal and overall mortality (up to 2 years of age) were predicted by low gestational age at delivery. Neonatal mortality was additionally predicted by absent or reversed UA end-diastolic flow, while the presence of severe neonatal complications and placental villitis were additional predictors of both infant (between 28 days and 1 year of postnatal life) and overall mortality. Placental villitis was found to be the only predictor of necrotizing enterocolitis. Low gestational age at delivery, male sex, abnormal cardiotocography, absent or reversed UA end-diastolic flow and the HELLP syndrome predicted respiratory distress syndrome. Abnormal neurodevelopmental outcome at 2 years was predicted by low birth weight (< 2.3(rd) percentile), fetal acidosis (UA pH < 7.00), and placental villitis. Less advanced gestation at delivery remains an important predictor of short-term outcome in growth-restricted fetuses. In addition, the presence of placental villitis may aid neonatologists in the early identification of infants at increased risk of necrotizing enterocolitis, death and abnormal neurodevelopment at 2 years of age. Abnormal neurodevelopment was related to low weight and acidosis at birth, indicating that the severity of malnutrition and fetal acidosis affect long-term outcome.

Aims/hypothesis The aim of this study was to examine the association between maternal gestational diabetes mellitus (GDM) and childhood obesity at age 9–11 years in 12 countries around the world. Methods A multinational cross-sectional study of 4,740 children aged 9–11 years was conducted. Maternal GDM was diagnosed according to the ADA or WHO criteria. Height and waist circumference were measured using standardised methods. Weight and body fat were measured using a portable Tanita SC-240 Body Composition Analyzer. Multilevel modelling was used to account for the nested nature of the data. Results The prevalence of reported maternal GDM was 4.3%. The overall prevalence of childhood obesity, central obesity and high body fat were 12.3%, 9.9% and 8.1%, respectively. The multivariable-adjusted (maternal age at delivery, education, infant feeding mode, gestational age, number of younger siblings, child unhealthy diet pattern scores, moderate-to-vigorous physical activity, sleeping time, sedentary time, sex and birthweight) odds ratios among children of GDM mothers compared with children of non-GDM mothers were 1.53 (95% CI 1.03, 2.27) for obesity, 1.73 (95% CI 1.14, 2.62) for central obesity and 1.42 (95% CI 0.90, 2.26) for high body fat. The positive association was still statistically significant for central obesity after additional adjustment for current maternal BMI but was no longer significant for obesity and high body fat. Conclusions/interpretation Maternal GDM was associated with increased odds of childhood obesity at 9–11 years old but this association was not fully independent of maternal BMI. PMID:27510911

Mycosis fungoides and Sézary syndrome (MF/SS) are rare in children and young adults, and thus the incidence and outcomes in this patient population are not well studied. To assess the incidence and outcomes of MF/SS in patients diagnosed before 30 years of age. Retrospective study of 2 population-based cancer registries-the California Cancer Registry (n = 204) and 9 US cancer registries of the Surveillance, Epidemiology, and End Results program (SEER 9; n = 195)-for patients diagnosed with MF/SS before 30 years of age. Overall survival was calculated by the Kaplan-Meier method. The risk of a second cancer was assessed by calculating the standard incidence ratio (SIR) comparing observed cancer incidence in patients with MF/SS with the expected incidence in the age-, sex-, and race-standardized general population. The incidence of MF/SS is rare before 30 years of age, with an incidence rate of 0.05 per 100,000 persons per year before age 20 years and 0.12 per 100,000 persons per year between ages 20 and 29 years in the California Cancer Registry. At 10 years, patients with MF/SS had an overall survival of 94.3% (95% CI, 89.6%-97.2%) in the California Cancer Registry and 88.9% (95% CI, 82.4%-93.2%) in SEER 9. In SEER 9, there was a significant excess risk of all types of second cancers combined (SIR, 3.40; 95% CI, 1.55-6.45), particularly lymphoma (SIR, 12.86; 95% CI, 2.65-37.59) and melanoma (SIR, 9.31; 95% CI, 8.75-33.62). In the California Cancer Registry, the SIR for risk of all types of second cancers was similar to that in SEER 9 (SIR, 3.45; 95% CI, 0.94-8.83), although not statistically significant. Young patients with MF/SS have a favorable outcome, despite a strong suggestion of an increased risk of second primary cancers. Prolonged follow-up is warranted to definitively assess their risk of developing second cancers in a lifetime.

Infliximab (IFX) is efficacious for induction and maintenance of remission in pediatric patients with moderate-to-severe inflammatory bowel disease (IBD). It has, however, not been studied in patients 7 years old and younger. Our aim was to characterize efficacy and safety of IFX therapy in this cohort. This was a retrospective study of patients with IBD ages 7 years and younger, treated with IFX between 1999 and 2011. Medical records were reviewed for age of diagnosis, disease phenotype, therapy, surgery, IFX infusion dates, dose, and intervals. Outcome measures included physician global assessment, corticosteroid requirement, and adverse events. Thirty-three children (ages 2.4-7 years) were included. Twenty patients had Crohn disease, 4 had ulcerative colitis, and 9 had indeterminate colitis. Maintenance of IFX therapy at 1, 2, and 3 years was 36%, 18%, and 12%, respectively. Patients of age 5 years and younger had the lowest rates of maintenance of therapy at 25% at year 1, and 10% at years 2 and 3 combined. Nine percent of all of the patients demonstrated response measured by the physician global assessment and were steroid free at 1 year. There were 8 infusion reactions. There were no malignancies, serious infections, or deaths. IFX demonstrated a modest response rate and a low steroid-sparing effect in patients with IBD 7 years old and younger. Although this is a limited study, there appears to be a trend for decreased sustained efficacy with IFX in this age group, particularly in children 5 years old and younger, when compared with the previously published literature in older children.

The age of dense interstellar cloud cores, where stars and planets form, is a crucial parameter in star formation and difficult to measure. Some models predict rapid collapse, whereas others predict timescales of more than one million years (ref. 3). One possible approach to determining the age is through chemical changes as cloud contraction occurs, in particular through indirect measurements of the ratio of the two spin isomers (ortho/para) of molecular hydrogen, H2, which decreases monotonically with age. This has been done for the dense cloud core L183, for which the deuterium fractionation of diazenylium (N2H(+)) was used as a chemical clock to infer that the core has contracted rapidly (on a timescale of less than 700,000 years). Among astronomically observable molecules, the spin isomers of the deuterated trihydrogen cation, ortho-H2D(+) and para-H2D(+), have the most direct chemical connections to H2 (refs 8, 9, 10, 11, 12) and their abundance ratio provides a chemical clock that is sensitive to greater cloud core ages. So far this ratio has not been determined because para-H2D(+) is very difficult to observe. The detection of its rotational ground-state line has only now become possible thanks to accurate measurements of its transition frequency in the laboratory, and recent progress in instrumentation technology. Here we report observations of ortho- and para-H2D(+) emission and absorption, respectively, from the dense cloud core hosting IRAS 16293-2422 A/B, a group of nascent solar-type stars (with ages of less than 100,000 years). Using the ortho/para ratio in conjunction with chemical models, we find that the dense core has been chemically processed for at least one million years. The apparent discrepancy with the earlier N2H(+) work arises because that chemical clock turns off sooner than the H2D(+) clock, but both results imply that star-forming dense cores have ages of about one million years, rather than 100,000 years.

The objective of the study was to evaluate preteen insulin and metabolic syndrome (MS) as independent predictors of impaired fasting glucose (IFG) and type 2 diabetes mellitus (T2DM) in black and white females by mean age of 24 years. This was a prospective cohort study. There were 8 measures of fasting glucose and insulin from mean age of 10 years through mean age of 24 years, and insulin also at mean age of 25 years. Childhood MS was defined by at least 3 abnormal values among waist circumference, triglyceride, high-density lipoprotein cholesterol, blood pressure, and glucose. Hyperinsulinemia was defined by insulin greater than or equal to race-specific 75th percentile. Patients with type 1 diabetes mellitus were excluded. The study was held in schools and in an outpatient clinical center. Participants were schoolgirls (260 white, 296 black). There was no intervention. The outcome measures were IFG (fasting glucose of at least 100 to 125 mg/dL) and T2DM (fasting glucose of at least 126 mg/dL). By the age of 24 years, there were 11 cases of T2DM (2%) and 108 cases of IFG (19%). By the age of 24 years, IFG + T2DM was present in 18% of women (73/412) who had normal insulin-no MS at the age of 10 years vs 28% (34/122) of those with high insulin-no MS at the age of 10 years (P = .014) and 67% (10/15) of those with high insulin + MS at the age of 10 years (P < .0001). By stepwise logistic regression, significant, independent, positive predictors of IFG + T2DM were first insulin measure in childhood, age at last sampling, childhood MS, change in body mass index over 15 years, and, separately, initial glucose of at least 100 mg/dL and average of all insulin quartile ranks over 15 years. The correlation between childhood insulin z score and insulin z score 15 years later was r = .30, P < .0001. Insulin and MS at a mean age of 10 years plus change in body mass index over 15 years, and 15-year average insulin rank independently predict IFG + T2DM by mean age of 24 years

As part of a risk-management approach, sound epidemiological data are needed to develop prevention programs. A recent review on soccer injuries of players younger than 19 years concluded that prospective data concerning children are lacking. To analyze the incidence and characteristics of soccer injuries in children aged 7 to 12 years. Descriptive epidemiological study. The present survey was a prospective descriptive epidemiological study on soccer injuries over 2 seasons in the Czech Republic and Switzerland. Exposure of players during training and match play (in hours) and injury data were reported by coaches via an Internet-based registration system. Location, type, and severity of injuries were classified according to an established consensus. Injury characteristics are presented as absolute numbers and injury incidence rates (injuries per 1000 hours of soccer exposure). An injury was defined as any physical complaint sustained during a scheduled training session or match play resulting in at least 1 of the following: (1) inability to complete the current match or training session, (2) absence from subsequent training sessions or matches, and (3) injury requiring medical attention. In total, 6038 player-seasons with 395,295 hours of soccer exposure were recorded. The mean (±SD) age of the players was 9.5 ± 2.0 years, and 3.9% of the participants were girls. A total of 417 injuries were reported. Most (76.3%) injuries were located in the lower limbs, with 15.6% located in the upper limbs. Joint and ligament injuries comprised 30.5%, contusions 22.5%, muscle and tendon injuries 18.5%, and fractures and bone injuries 15.4% of all injuries; 23.7% of injuries led to more than 28 days of absence from sport participation. The overall injury incidence was 0.61 (95% CI, 0.53-0.69) injuries per 1000 hours of soccer exposure during training sessions and 4.57 (95% CI, 4.00-5.23) during match play. Injury incidence rates increased with increasing age. The observed injury

Abstract This study characterized guaifenesin pharmacokinetics in children aged 2 to 17 years (n = 40) who received a single oral dose of guaifenesin (age‐based doses of 100‐400 mg) 2 hours after breakfast. Plasma samples were obtained before and for 8 hours after dosing and analyzed for guaifenesin using liquid chromatography‐tandem mass spectrometry. Pharmacokinetic parameters were estimated using noncompartmental methods, relationships with age were assessed using linear regression, and dose proportionality was assessed on 95% confidence intervals. Based on the upper dose recommended in the monograph (for both children and adolescents), area under the curve from time zero to infinity and maximum plasma concentration both increased with age. However, when comparing the upper dose for children aged 2 to 11 years with the lower dose for adolescents aged 12 to 17 years, similar systemic exposure was observed. As expected due to increasing body size, oral clearance (CLo) and terminal volume of distribution (Vz/F) increased with age. Due to a larger increase in Vz/F than CLo, an increase in terminal exponential half‐life was also observed. Allometric scaling indicated no maturation‐related changes in CLo and Vz/F. PMID:26632082

Background & Aims Childhood obesity is increasing and is associated with adult obesity. Antibiotics have been used to promote weight gain in livestock for several decades. Antibiotics are commonly prescribed for children, but it is not clear how exposure to antibiotics early in life affects risk for obesity. We performed a population-based cohort study to assess the association between antibiotic exposure before age 2 years and obesity at age 4 years. Methods We performed a retrospective cohort study of 21,714 children in The Health Improvement Network —a population-representative dataset of more than 10 million individuals derived from electronic medical records from 1995 through 2013 in the United Kingdom. Eligible subjects were registered within 3 months of birth with complete follow-up and height and weight were recorded within 12 months of their 4th birthday. Antibiotic exposure was assessed before age 2 years, and classified based on anti-anaerobic activity. The primary outcome was obesity at age 4 years. We performed logistic regression analyses, adjusting for maternal and sibling obesity, maternal diabetes, mode of delivery, socioeconomic status, year and country of birth, and urban dwelling. Results In the cohort, 1306 of the children (6.4%) were obese at 4 years of age. Antibiotic exposure was associated with an increased risk of obesity at 4 years (odds ratio [OR]=1.21; 95% confidence interval [CI], 1.07–1.38). Odds ratios increased with repeated exposures: for 1–2 prescriptions, OR=1.07 (95% CI, 0.91–1.23); for 3–5 prescriptions, OR=1.41 (95% CI, 1.20–1.65); for 6 or more prescriptions, OR=1.47 (95% CI, 1.19–1.82). Antifungal agents were not associated with obesity (OR=0.81; 95% CI, 0.59–1.11). Conclusions Administration of 3 or more courses of antibiotics before children reach an age of 2 years is associated with an increased risk of early childhood obesity. PMID:27003602

We performed a population-based cohort study to assess the association between antibiotic exposure before age 2 years and obesity at age 4 years. We performed a retrospective cohort study of 21,714 children in The Health Improvement Network-a population-representative dataset of >10 million individuals derived from electronic medical records from 1995 through 2013 in the United Kingdom.

The aim of this study was to assess direct health costs in children with pertussis aged 0-9 years who were vaccinated, partially vaccinated, and unvaccinated during childhood, and to assess the association between pertussis costs and pertussis vaccination in Catalonia (Spain) in 2012-2013. Direct healthcare costs included pertussis treatment, pertussis detection, and preventive chemotherapy of contacts. Pertussis patients were considered vaccinated when they had received 4-5 doses, and unvaccinated or partially vaccinated when they had received 0-3 doses of vaccine. The Chi square test and the odds ratios were used to compare percentages and the t test was used to compare mean pertussis costs in different groups, considering a p < 0.05 as statistically significant. The correlation between pertussis costs and study variables was assessed using the Spearman's ρ, with a p < 0.05 as statistically significant. Multiple linear regression analysis (IBM-SPSS program) was used to quantify the association of pertussis vaccination and other study variables with pertussis costs. Vaccinated children with pertussis aged 0-9 years had significantly lower odds ratios of hospitalizations (OR 0.02, p < 0.001), laboratory confirmation (OR 0.21, p < 0.001), and severe disease (OR 0.02, p < 0.001) than unvaccinated or partially vaccinated children with pertussis of the same age. Mean direct healthcare costs were significantly lower (p < 0.001) in vaccinated patients (€190.6) than in unvaccinated patients (€3550.8), partially vaccinated patients (€1116.9), and unvaccinated/partially vaccinated patients (€2330). Multivariable linear regression analysis showed that pertussis vaccination with 4-5 doses was associated with a non-significant reduction of pertussis costs of €107.9 per case after taking into account the effect of other study variables, and €200 per case after taking into account pertussis severity. Direct healthcare costs were lower in

To assess adolescent and young adult determinants of visceral adipose tissue (VAT) at ages 26-28 years. Prospective study (ages 9-28 years) of cardiometabolic measures, menarche age, menses irregularities, metabolic syndrome, impaired fasting glucose-type 2 diabetes mellitus, and VAT in 400 girls (248 black, 152 white). Adolescent (age 14-19) independent variables for greater VAT at ages 26-28 included larger mean waist circumference (partial R(2) = 30.8%), earlier age at menarche (0.9%), and white race (1.8%). Young adult (ages 20-28 years) independent variables for greater VAT included larger mean waist circumference (partial R(2) = 61.7%), greater triglyceride levels (3.3%), lower high-density lipoprotein cholesterol (1.0%), and greater insulin resistance (homeostasis model assessment-estimated insulin resistance; 0.4%). Independent variables for greater VAT when both adolescent and young adult variables were used included waist (tertile rank change from adolescence to young adulthood, partial R(2) = 58.3%), greater young adult triglyceride levels (4.4%), white race (1.8%), greater young adult homeostasis model assessment-estimated insulin resistance (age 20-28, 2.4%), and earlier menarche age (0.7%). Menses irregularities were not independently associated with young adult VAT. Adolescent girls with early menarche and larger waist circumference should be targets for primary prevention of accretion of VAT. In young adulthood, VAT is associated with dysregulated cardiometabolic profiles, which is greater for those with waist circumference increases from adolescence to adulthood. Waist circumference during young adulthood, and to a lesser degree during adolescence, is an inexpensive surrogate for VAT at ages 26-28 years. Copyright © 2015 Elsevier Inc. All rights reserved.

Age-specific and sex-specific morbidity and mortality from avian influenza A(H7N9).

We used data on age and sex for 136 laboratory confirmed human A(H7N9) cases reported as of 11 August 2013 to compare age-specific and sex-specific patterns of morbidity and mortality from the avian influenza A(H7N9) virus with those of the avian influenza A(H5N1) virus. Human A(H7N9) cases exhibit high degrees of age and sex bias: mortality is heavily biased toward males >50 years, no deaths have been reported among individuals <25 years old, and relatively few cases documented among children or adolescents. The proportion of fatal cases (PFC) for human A(H7N9) cases as of 11 August 2013 was 32%, compared to a cumulative PFC for A(H5N1) of 83% in Indonesia and 36% in Egypt. Approximately 75% of cases of all A(H7N9) cases occurred among individuals >45 years old. Morbidity and mortality from A(H7N9) are lowest among individuals between 10 and 29 years, the age group which exhibits the highest cumulative morbidity and case fatality rates from A(H5N1). Although individuals <20 years old comprise nearly 50% of all human A(H5N1) cases, only 7% of all reported A(H7N9) cases and no deaths have been reported among individuals in this age group. Only 4% of A(H7N9) cases occurred among children<5 years old, and only one case from the 10 to 20 year age group. Age- and sex-related differences in morbidity and mortality from emerging zoonotic diseases can provide insights into ecological, economic, and cultural factors that may contribute to the emergence and proliferation of novel zoonotic diseases in human populations.

Higher pulse wave velocity (PWV) reflects increased arterial stiffness and is an established cardiovascular risk marker associated with lower long-chain n-3 polyunsaturated fatty acid intake in adults. Experimentally, maternal fatty acid intake in pregnancy has lasting effects on offspring arterial stiffness. To examine the association between maternal consumption of oily fish, a source of long-chain n-3 polyunsaturated fatty acids, in pregnancy and child's aortic stiffness age 9 years. In a mother-offspring study (Southampton Women's Survey), the child's descending aorta PWV was measured at the age of 9 years using velocity-encoded phase-contrast MRI and related to maternal oily fish consumption assessed prospectively during pregnancy. Higher oily fish consumption in late pregnancy was associated with lower childhood aortic PWV (sex-adjusted β=-0.084 m/s per portion per week; 95% confidence interval, -0.137 to -0.031; P=0.002; n=226). Mother's educational attainment was independently associated with child's PWV. PWV was not associated with the child's current oily fish consumption. Level of maternal oily fish consumption in pregnancy may influence child's large artery development, with potential long-term consequences for later cardiovascular risk. © 2015 American Heart Association, Inc.

OBJECTIVES To examine the associations of cumulative physical activity (PA) and its changes over 3-year with changes over 9 years of follow-up in physical performance in older adults. DESIGN Longitudinal. SETTING Community-based. PARTICIPANTS Men and women, aged 65 years and older, from the InCHIANTI study (N=782). MEASUREMENTS Physical performance was assessed at baseline and at 3-, 6- and 9-year follow-up with the Short Physical Performance Battery (SPPB). PA was assessed through an interviewer-administered questionnaire at baseline and at 3-year follow-up. Analyses were adjusted for education, body mass index, smoking, alcohol intake, coronary heart disease, stroke, peripheral arterial disease, cancer, lung disease, lower extremity osteoarthritis, depression, and Mini-mental state examination. RESULTS Over 3-year of follow-up, the prevalence of participants inactive, minimally active and active was 27.8%, 52.2% and 20.0%, respectively. The prevalence of participants who decreased, no change or increased PA over 3-year of follow-up was 37.2%, 50.1% and 12.7%, respectively. Compared with participants who spent most of the time inactive and after adjustment for potential covariates (−2.60 score, 95%CI: −2.92, −2.27), being mostly active (−1.08 score, 95%CI: −1.43, −0.73) and even minimally active (−1.33 score, 95%CI: −1.53, −1.12) over 3 years of follow-up was associated with lower declines in the SPPB score. When analyzing changes, increasing PA (−0.57 score, 95%CI: −1.01, −0.12) was associated with lower declines in the SPPB score over 9 years as compared with those who decreased PA (−2.16 score, 95%CI: −2.42, −1.89). CONCLUSION Maintaining or increasing PA levels may attenuate age-associated physical performance decline. PMID:28248412

Maternal obesity, excessive gestational weight gain (EGWG), gestational diabetes mellitus (GDM) and breastfeeding are four important factors associated with childhood obesity. The objective of the study was to assess the interplay among these four factors and their independent contributions to childhood overweight in a cohort with standard clinical care. The cohort included 15 710 mother-offspring pairs delivered in 2011. Logistic regression was used to assess associations between maternal exposures and childhood overweight (body mass index >85th percentile) at age 2 years. Mothers with pre-pregnancy obesity or overweight were more likely to have EGWG, GDM and less likely to breastfeed ≥6 months. Mothers with GDM had 40-49% lower EGWG rates and similar breastfeeding rates compared with mothers without GDM. Analysis adjusted for exposures and covariates revealed an adjusted odds ratio (95% confidence interval) associated with childhood overweight at age 2 years of 2.34 (2.09-2.62), 1.50 (1.34-1.68), 1.23 (1.12-1.35), 0.95 (0.83-1.10) and 0.76 (0.69-0.83) for maternal obesity, overweight, EGWG, GDM and breastfeeding ≥6 months vs. <6 months, respectively. In this large clinical cohort, GDM was not associated with, but maternal pre-pregnancy obesity or overweight and EGWG were independently associated with an increased risk, and breastfeeding ≥6 months was associated with a decreased risk of childhood overweight at age 2 years. © 2016 World Obesity Federation.

Background The impact of improved nutritional status on health-related quality of life (HRQOL) is unknown for children with cystic fibrosis (CF). Methods Associations between nutritional status and HRQOL were examined over 2 years in 95 children, aged 9–19 years, who were followed in the Wisconsin Newborn Screening Project. HRQOL was assessed using the Cystic Fibrosis Questionnaire (CFQ). Associations between height z-score (HtZ), BMI z-score (BMIZ) and seven CFQ dimensions were evaluated. Results Mean values of at least 80 were observed for all CFQ dimensions except respiratory symptoms and treatment burden. Treatment burden was significantly worse in patients with meconium ileus (57) compared to pancreatic insufficient (65) and sufficient (78) subjects, p<0.0001. HtZ and BMIZ were positively associated with physical functioning and body image (p<0.05). Conclusions Better nutritional status was associated with increased HRQOL scores. Early diagnosis through newborn screening and improved nutrition provides an opportunity to enhance quality of life and body image perception. PMID:23410621

Prevalence of overweight, obesity and thinness in 9–10 year old children in Mauritius

2012-01-01

Objective To document the prevalence of overweight, obesity and thinness in 9–10 year old children in Mauritius. Methods 412 boys and 429 girls aged 9–10 years from 23 primary schools were selected using stratified cluster random sampling. All data was cross-sectional and collected via anthropometry and self-administered questionnaire. Outcome measures were BMI (kg/m2), prevalence of overweight, obesity (International Obesity Task Force definitions) and thinness (low BMI for age). Linear and logistic regression analyses, accounting for clustering at the school level, were used to assess associations between gender, ethnicity, school location, and school's academic performance (average) to each outcome measure. Results The distribution of BMI was marginally skewed with a more pronounced positive tail in the girls. Median BMI was 15.6 kg/m2 in boys and 15.4 kg/m2 in girls, respectively. In boys, prevalence of overweight was 15.8% (95% CI: 12.6, 19.6), prevalence of obesity 4.9% (95% CI: 3.2, 7.4) and prevalence of thinness 12.4% (95% CI: 9.5, 15.9). Among girls, 18.9% (95% CI: 15.5, 22.9) were overweight, 5.1% (95% CI: 3.4, 7.7) were obese and 13.1% (95% CI: 10.2, 16.6) were thin. Urban children had a slightly higher mean BMI than rural children (0.5 kg/m2, 95% CI: 0.01, 1.00) and were nearly twice as likely to be obese (6.7% vs. 4.0%; adjusted odds ratio 1.6; 95% CI: 0.9, 3.5). Creole children were less likely to be classified as thin compared to Indian children (adjusted odds ratio 0.3, 95% CI: 0.2, 0.6). Conclusion Mauritius is currently in the midst of nutritional transition with both a high prevalence of overweight and thinness in children aged 9–10 years. The coexistence of children representing opposite sides of the energy balance equation presents a unique challenge for policy and interventions. Further exploration is needed to understand the specific causes of the double burden of malnutrition and to make appropriate policy recommendations

The objective was to determine the frequency of headache subtypes, according to International Headache Society (IHS) criteria, in a population of children below 6 years visiting a Center for Diagnosis and Treatment of Headache in Youth. Medical records of the children below 6 years at their first visit, admitted for headache between 1997 and 2003, were studied. Headache was classified according to the IHS criteria 2004. Children with less than three headache attacks or less than 15 days of daily headache were excluded. We found 1598 medical records of children who visited our Headache Center in the study period. One hundred and five (6.5%) were children younger than 6 years. The mean age at the first medical control was 4.8+/-1.3 years (range 17-71 months). There were 59 males (56.1%) and 46 females (43.9%). The mean age at onset of headaches was 4.3 years (range 14-69 months). According to the IHS criteria we found 37 cases (35.2%) with migraine, 19 cases (18%) with episodic tension headache, 5 cases (4.8%) with chronic daily headache, 13 cases (12.4%) with primary stabbing headache, 18 cases (17.1%) with post-traumatic headache, 7 cases (6.6%) with other non-dangerous secondary headaches (otorhinolaryngological diseases, post-infectious headaches), 3 cases (2.85%) with dangerous headaches (Arnold-Chiari type 1 malformation, brain tumour) and 9 cases (8.6%) with unclassifiable headaches. Six children (5.7%) reported more than one headache subtype. The prevalence of dangerous headaches was higher than those in school age (chi(2)=4.70, p<0.05). Our study shows some differences in headaches in this population vs. school children. In fact at this age migraine is the most common headache, but we also found an increase of secondary causes among the chronic/recurrent and daily headaches, especially posttraumatic disorders and potentially dangerous headaches. Finally our study shows the highest prevalence of the idiopathic stabbing headache in pre-school children in

Suprasegmental Characteristics of Spontaneous Speech Produced in Good and Challenging Communicative Conditions by Talkers Aged 9-14 Years.

This study investigated the acoustic characteristics of spontaneous speech by talkers aged 9-14 years and their ability to adapt these characteristics to maintain effective communication when intelligibility was artificially degraded for their interlocutor. Recordings were made for 96 children (50 female participants, 46 male participants) engaged in a problem-solving task with a same-sex friend; recordings for 20 adults were used as reference. The task was carried out in good listening conditions (normal transmission) and in degraded transmission conditions. Articulation rate, median fundamental frequency (f0), f0 range, and relative energy in the 1- to 3-kHz range were analyzed. With increasing age, children significantly reduced their median f0 and f0 range, became faster talkers, and reduced their mid-frequency energy in spontaneous speech. Children produced similar clear speech adaptations (in degraded transmission conditions) as adults, but only children aged 11-14 years increased their f0 range, an unhelpful strategy not transmitted via the vocoder. Changes made by children were consistent with a general increase in vocal effort. Further developments in speech production take place during later childhood. Children use clear speech strategies to benefit an interlocutor facing intelligibility problems but may not be able to attune these strategies to the same degree as adults.

To report the prevalence and trend of overweight and obesity among students aged 7-22 years in Jiangsu, 2010 to 2013. This cross-sectional study was carried out as part of students physical fitness and health survey in Jiangsu province. A total of 255,581 subjects (50.03% males and 49.97% females) enrolled in 82 school and 10 universities in Jiangsu. Weights and heights were obtained for each subject and its body mass index (BMI) was calculated using the Chinese Working Group on Obesity in China (CWGO). Anthropometric measurement including bodyweight, height, BMI and bust were significantly different between males in urban compared to females living rural areas (P<0.001). The total prevalence of overweight and obesity was 12.4% and 5.7%. Males had a significantly higher rate than in female's student. The prevalence of overweight and obesity by age groups was (14.5%, 10.3%) at age 7-11 years, (11.2%, 6.8%) at age 12-14 years, (11.7%, 3.1%) at age 15-17 years, and (11.4%, 2.3%) at age 18-22 years. By regions; the highest prevalence of overweight obesity reported in Taizhou (10%, 14.2%), Xuzhou (9.4%, 12.5%), and Nanjing (9.2%, 15.6%), respectively. The finding declares that overweight and obesity are important health problems among students in Jiangsu Province. Early intervention programme are needed to address this problems.

preservation of cognitive abilities is required to have a good quality of life. The predictive value of cognitive functioning at 65 years old on successful ageing 6 years later is not established. nine hundred and seventy-six questionnaires were sent by mail to a sample of healthy and voluntary French pensioners. Successful ageing was defined through health status and well-being. Cognitive abilities had been assessed 6 years earlier according to an objective method (Free and Cued Selective Recall Reminding Test (FCSRT), the Benton visual retention test and the similarities subtest of the Wechsler Adult Intelligence Scale-Revised) and a subjective one (Goldberg's anxiety scale, Mac Nair's scale and a Visual Analogue Scale to evaluate memory abilities change in the last 5 years). six hundred and eighty-six questionnaires could be analysed. The mean age was 72.9 ± 1.2 years old with 59% of women and 99% lived at home. Well-being was negatively correlated with the FCSRT (r = -0.08, P = 0.0318) but positively related with the Benton (r = 0.09, P = 0.0125) and the similarities tests (r = 0.09, P = 0.0118). There is a negative correlation between anxious and cognitive complaints measured at baseline, and successful ageing indicators 6 years later. preservation of cognitive abilities at the age of retirement can predict a successful ageing 6 years later.

The Canadian Society for Exercise Physiology (CSEP), with assistance from multiple partners, stakeholders, and researchers, developed the first Canadian Sedentary Behaviour Guidelines for the Early Years (aged 0-4 years). These national guidelines are in response to a call from health and health care professionals, child care providers, and fitness practitioners for guidance on sedentary behaviour in the early years. The guideline development process followed the Appraisal of Guidelines for Research Evaluation (AGREE) II framework. The recommendations are informed by evidence from a systematic review that examined the relationships between sedentary behaviour (predominantly screen time) and health indicators (healthy body weight, bone and skeletal health, motor skill development, psychosocial health, cognitive development, and cardio-metabolic disease risk factors) for three age groups (infants aged <1 year; toddlers aged 1-2 years; preschoolers aged 3-4 years). Evidence from the review was assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system. The new guidelines include a preamble to provide context, followed by the specific recommendations. The final guidelines benefitted from extensive on-line consultations with input from >900 domestic and international stakeholders, end-users, and key informants. The final guidelines state: for healthy growth and development, caregivers should minimize the time infants (aged <1 year), toddlers (aged 1-2 years), and preschoolers (aged 3-4 years) spend being sedentary during waking hours. This includes prolonged sitting or being restrained (e.g., stroller, high chair) for more than 1 h at a time. For those under 2 years, screen time (e.g., TV, computer, electronic games) is not recommended. For children 2-4 years, screen time should be limited to under 1 h per day; less is better.

In Singapore, 2 rotavirus vaccines were licensed in October 2005 and July 2007, respectively, for vaccinating infants aged ≥ 6 weeks against rotavirus gastroenteritis. These vaccines are optional and are not included in the National Childhood Immunization Program. This study aimed to determine the incidence of rotavirus gastroenteritis-associated hospitalizations among children <5 years of age. Children <5 years, who were hospitalized for acute gastro enteritis, were enrolled between September 2005 and April 2008. Stool samples were tested for the presence and serotyping of rotavirus. Incidence and proportion of gastroenteritis and rotavirus gastroenteritis cases were calculated with 95% confidence intervals. Among 1976 children included in the according-to-protocol cohort, 781 were rotavirus positive with a median age of 24 months (range: 0-59 months). The overall incidence of rotavirus gastroenteritis hospitalizations during the entire study period in children <5 years of age was 4.6 (95% confidence interval: 4.3-4.9) per 1000 person-years with the highest number of cases observed in children 13-24 months of age (26.5%). G1P[8] (18.3%) and G9P[8] (9.9%) were the most common rotavirus types. Rotavirus gastroenteritis hospitalizations peaked between January and March. Rotavirus infection was the primary cause of acute gastro enteritis hospitalizations among children <5 years of age, constituting nearly one-third of gastroenteritis hospitalizations in Singapore. The predominant strain observed in Singapore was G1P[8]. Results of this study suggest the need for implementation of rotavirus vaccination into National Childhood Immunization Program in Singapore.

The MacArthur–Bates Communicative Development Inventories (CDI; Dale, 1996; Fenson et al., 1994), parent reports about language skills, are being used increasingly in studies of theoretical and public health importance. This study (N = 113) correlated scores on the CDI at ages 2 and 3 years with scores at age 3 years on tests of cognition and receptive language and measures from parent–child conversation. Associations indicated reasonable concurrent and predictive validity. The findings suggest that satisfactory vocabulary scores at age 2 are likely to predict normal language skills at age 3, although some children with limited skills at age 3 will have had satisfactory scores at age 2. Many children with poor vocabulary scores at 2 will have normal skills at 3. PMID:16026501

Inadequate vitamin D status is associated with secondary hyperparathyroidism and increased bone turnover and bone loss, which in turn increases fracture risk. The objective of this study is to assess the prevalence of inadequate vitamin D status in European women aged over 80 years. Assessments of serum 25-hydroxyvitamin D levels (25(OH)D) were performed on 8532 European women with osteoporosis or osteopenia of which 1984 were aged over 80 years. European countries included in the study were: France, Belgium, Denmark, Italy, Poland, Hungary, United Kingdom, Spain and Germany. Two cut-offs of 25(OH)D inadequacy were fixed: <75 nmol/L (30 ng/ml) and <50 nmol/L (20 ng/ml). Mean (SD) age of the patients was 83.4 (2.9) years, body mass index was 25.0 (4.0) kg/m(2) and level of 25(OH)D was 53.3 (26.7) nmol/L (21.4 [10.7] ng/ml). There was a highly significant difference of 25(OH)D level across European countries (p<0.0001). In these women aged over 80 years, the prevalence of 25(OH)D inadequacy was 80.9% and 44.5% when considering cut-offs of 75 and 50 nmol/L, respectively. In the 397 (20.0%) patients taking supplemental vitamin D with or without supplemental calcium, the mean serum 25(OH)D level was significantly higher than in the other patients (65.2 (29.2) nmol/L vs. 50.3 (25.2) nmol/L; P<0.001). This study indicates a high prevalence of vitamin D (25(OH)D) inadequacy in old European women. The prevalence could be even higher in some particular countries.

To determine the prevalence of dementia in Thai people with age 45 years and above. This project used a cross sectional research design to study the prevalence of dementia in Chiang Mai. Door-to-door technique was assigned in condition with multi-stage probability random sampling to obtain subjects representing the population of Chiang Mai between Oct 2004 and Sep 2005. The researchers collected the data from the subjects aged 45 years and above. All subjects were located from every Amphurs of Chiang Mai. They were first screened with Thai Mini Mental State Examination (TMSE) and Thai Beck Depression Inventory (BDI). The subjects whose TMSE was less than 24 were assessed and diagnosed by a neurologist. Subjects who were determined as having dementia might be laboratory analyzed and classified based on DSM-IV and NINDS-AIREN criteria. The authors enrolled 2,311 people and screened them with Batteries test. One thousand four hundred ninety two people qualified with 610 males and 882 females, whose mean age was 59.7 +/- 10.4 years. The authors found that among the 35 people with dementia, the mean age was 67.9 +/- 8.9 years (45-88 years). The prevalence of dementia among the study participants was 2.35%. In the present study, Alzheimer's disease was the most common type of dementia diagnosed (75.0%) and vascular dementia was the second most commonly diagnosed (12.5%). The prevalence of dementia in Chiang Mai was 2.35%, which does not differ from the previous study Alzheimer's disease was the most common type of dementia diagnosed.

Obesity is widespread in the world including developing countries. However malnutrition in poor areas is still a serious problem. Few investigations, especially in a large sample, have been performed in Western area of China. This study aimed to evaluate the nutritional status of school children aged 9-15 years in large Southwest city of China, and identify the differential impact of aberrant birth categories and family history of obesity related disease on childhood overweight and obesity development. A multistage random cluster sampling was performed to evaluate the prevalence of thinness, overweight and obesity, which were defined by the new age-, sex-, specific BMI reference developed by World Health Organization (WHO) (2007). And then a frequency matched case-control study was performed to identify the risk factors of overweight and obesity. 7,194 children (3,494 boys, 3,700 girls) were recruited, and 1,282 (17.8%) had excess bodyweight (14.5% overweight, 3.3% obesity). The combined prevalence gradually decreased with age, and were more prevalent among boys than girls (P <0.05). Meanwhile 6.3% were found thinness and there were little differences in genders (P >0.05). Preterm large for gestational age (OR = 2.746), maternal history of obesity related disease (OR = 1.713), paternal history of obesity related disease (OR = 1.583), preterm appropriate for gestational age (OR = 1.564), full term small for gestational age (OR = 1.454) and full term large for gestational age (OR = 1.418) were recognized as significant risk factors in the multivariate regression analysis (P <0.05). While overweight and obesity was dramatically spreading, malnutrition still remained a serious problem. This unmatched nutritional status should be emphasized in backward cities of China. Children born of both preterm and LGA, whose parents particularly mothers had a history of obesity related disease, should be emphatically intervened as early as possible.

The clinical severity of phenylalanine hydroxylase deficiency is usually defined by either pre-treatment phenylalanine (Phe) concentration or Phe tolerance at 5 years of age. So far, little is known about the course of Phe tolerance or the ability of both pre-treatment Phe and Phe tolerance at early age to predict Phe tolerance at later age. This study was conducted to investigate the course of the individual Phe tolerance and to assess the predictive value of both the pre-treatment Phe concentration and Phe tolerance at 1 and 6 months and 1, 2, 3 and 5 years for Phe tolerance at 10 years of age. Data on blood Phe concentration, prescribed Phe intake and weight of 213 early and continuously treated Dutch PKU patients up to 10 years of age were collected. Data acquired under good metabolic control were used in the study. Tolerance was expressed in mg/day and mg/kg per day. Data at 1 and 6 months and at 1, 2, 3 and 5 years of 61, 58, 59, 57, 56 and 59 patients were included for comparison with the Phe tolerance at 10 years. Phe tolerances (mg/kg per day) at 2, 3 and 5 years showed a clear correlation with the tolerance at 10 years of age (r = 0.608, r = 0.725 and r = 0.661). Results for tolerance expressed as mg/day were comparable. Pre-treatment Phe concentrations did not correlate significantly with the tolerance. Pre-treatment Phe is unreliable but Phe tolerance is a reliable predictor of the tolerance at 10 years of age, starting at 2 years of age.

Preventing child mental health problems and child obesity have been recognized as public health priorities. The aim of the present study was to examine whether being breastfed (at all or exclusively) in infancy was a predictor of mental well-being and protective against risk of obesity at age 9. Cross-sectional data from a large, nationally representative cohort study in the Republic of Ireland was used (n = 8357). Data on breastfeeding were retrospectively recalled. Child mental well-being was assessed using a parent-completed Strengths and Difficulties Questionnaire (SDQ). Child's height and weight were measured using scientifically calibrated instruments. Logistic regression analyses indicated that, after controlling for a wide range of potential confounding variables, being breastfed in infancy was associated with a 26% (P < 0.05) reduction in the risk of an abnormal SDQ score at 9 years. Being breastfed remained a significant predictor of child mental well-being when child obesity was controlled for, indicating that being breastfed, independent of child obesity, is a predictor of child mental well-being. The results of a second logistic regression indicated that, after controlling for a wide range of potential confounding variables, being breastfed for between 11 and 25 weeks was associated with a 36% (P < 0.05) reduction in the risk of obesity at 9 years, while being breastfed for 26 weeks or longer was associated with a 48% (P < 0.01) reduction in the risk of obesity at 9 years. Breastfeeding in infancy may protect against both poor mental well-being and obesity in childhood. © 2013 John Wiley & Sons Ltd.

The diagnostic performance of histidine-rich protein 2 (HRP-2)–based malaria rapid diagnostic test (RDT) was evaluated in a mesoendemic area for malaria, Kaduna, Nigeria. We compared RDT results with expert microscopy results of blood samples from 295 febrile children under 5 years. Overall, 11.9% (35/295) tested positive with RDT compared with 10.5% (31/295) by microscopy: sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were 100%, 98.5%, 88.6%, and 100%, respectively. The RDT sensitivity was not affected by transmission season, parasite density, and age. Specificity and positive PV decreased slightly during the high-transmission season (97.5% and 83.3%). The RDT test positivity rates in the low- and high-transmission seasons were 9.4% and 13.5%, respectively. Overall, the test performance of this RDT was satisfactory. The findings of a low proportion of RDT false positives, no invalid and no false-negative results should validate the performance of RDTs in this context. PMID:25711608

There are limited objective measures of the severity of lung disease before children are able to routinely perform spirometry, generally at age 6 years. Identifying risk factors for reduced lung function at age 6 provides opportunities to intervene and slow the progression of cystic fibrosis (CF) lung disease. To evaluate early childhood predictors of lung function at age 6-7 in a large U.S. CF cohort in the current era of widespread early eradication therapy for Pseudomonas aeruginosa (P. aeruginosa). Participants were children with CF enrolled before age 4 in the Early Pseudomonas Infection Control (EPIC) Observational Study, a multicenter, longitudinal study that enrolled P. aeruginosa-negative children not exceeding 12 years of age. Linear regression was used to estimate the association between potential early childhood risk factors and the best FEV1% predicted at age 6-7 years. Four hundred and eighty-four children (of 1,797 enrolled in the EPIC Observational Study) met the eligibility criteria for this analysis. Mean (SD) age at enrollment was 2.0 (1.3) years. In a multivariable model adjusted for age at enrollment, the following risk factors were significantly associated with lower mean (95% confidence interval) FEV1% predicted at age 6-7: weight percentile less than 10% during the year of enrollment (-5.3 [-9.1, -1.5]), P. aeruginosa positive during the year of enrollment (-2.8 [-5.7, 0.0]), crackles or wheeze during the year of enrollment (-5.7 [-9.4, -1.9]), mother's education of high school or less (-4.2 [-7.3, -1.2]), and mother smoked during pregnancy (-4.4 [-8.8, 0.1]). In this large U.S. cohort, we identified several early childhood risk factors for lower FEV1 at age 6-7 years, most of which are modifiable.

Objective Poor nutrition is thought to predispose to externalizing behavior problems, but to date there appear to have been no prospective longitudinal studies testing this hypothesis. This study assessed whether 1) poor nutrition at age 3 years predisposes to antisocial behavior at ages 8, 11, and 17 years, 2) such relationships are independent of psychosocial adversity, and 3) IQ mediates the relationship between nutrition and externalizing behavior problems. Method The participants were drawn from a birth cohort (N=1,795) in whom signs of malnutrition were assessed at age 3 years, cognitive measures were assessed at ages 3 and 11 years, and antisocial, aggressive, and hyperactive behavior was assessed at ages 8, 11, and 17 years. Results In relation to comparison subjects (N=1,206), the children with malnutrition signs at age 3 years (N=353) were more aggressive or hyperactive at age 8 years, had more externalizing problems at age 11, and had greater conduct disorder and excessive motor activity at age 17. The results were independent of psychosocial adversity and were not moderated by gender. There was a dose-response relationship between degree of malnutrition and degree of externalizing behavior at ages 8 and 17. Low IQ mediated the link between malnutrition and externalizing behavior at ages 8 and 11. Conclusions These results indicate that malnutrition predisposes to neurocognitive deficits, which in turn predispose to persistent externalizing behavior problems throughout childhood and adolescence. The findings suggest that reducing early malnutrition may help reduce later antisocial and aggressive behavior. PMID:15514400

Altered brain volumes and associations between volumes and developmental outcomes have been reported in prematurely born children. To assess which regional brain volumes are different in very low birth weight (VLBW) children without neurodevelopmental impairments ([NDI] cerebral palsy, hearing loss, blindness and significantly delayed cognitive performance) compared with VLBW children with NDI, and to evaluate the association between regional brain volumes at term-equivalent age and cognitive development and neurological performance at a corrected age of 2 years. The study group consisted of a regional cohort of 164 VLBW children, divided into one group of children without NDI (n = 148) and one group of children with NDI (n = 16). Brain (MRI) was performed at term-equivalent age, from which brain volumes were manually analysed. Cognitive development was assessed with the Bayley Scales of Infant Development II (BSID-II), and neurological performance with the Hammersmith Infant Neurological Examination at the corrected age of 2 years. The volumes of total brain tissue, cerebrum, frontal lobes, basal ganglia and thalami, and cerebellum were significantly smaller, and the volume of the ventricles significantly larger, in the children with NDI than in those without NDI. Even in children without NDI, a smaller cerebellar volume was significantly correlated with poor neurological performance at 2 years of corrected age. Volumetric analysis at brain MRI can provide an additional parameter for early prediction of outcome in VLBW children.

To describe the status of snacks consumption, the characteristics, and the contribution to their diet and nutrients intake in Chinese children and adolescents at the ages of 3-17 years. Chinese health and nutritional survey (1991-2004), Chinese National nutrition and health survey (2002), and 2007 typical survey on snacks in Chinese residents were used in this report. The incidence of snacks consumption and snacking contribution were calculated by consecutive day 3 dietary recalls of the first 2 surveys. At least 1 snacks intake in 3 days was snacking consumption. The incidences of snacks consumption in Chinese population at the ages of 3-17 years were increased from 1991 (13.2%) to 2004 (19.3%). There were 35.1% of Chinese children and adolescents consuming snacks, 55.7% in urban and 29.6% in rural. Snacks provided 7.7% of total daily energy, 18.2% of fiber, 17.9% of VC, 9.9% of calcium, 9.7% of VE, 6.9% of iron and 6.3% of zinc. The snacks were mainly consumed in the evening. The main reasons were not nutrition of food but good taste, thirsty or hungry and food advertisement. The location of snacking was mainly at home and school. The snacks came from parents or other family members. They also buy snacks themselves. The consumption of candies and chocolate, jelly more than 4-6 day a week had a certain proportion. It was important to supervise snacks selection and consumption in Chinese children and adolescents at the ages of 3-17 years. The limitations of snacks consumption data perhaps lowed underestimate the effects of snacks to dietary intake.

QuickStats: Brain Cancer Death Rates Among Children and Teens Aged 1-19 Years,* by Sex† and Age Group - United States, 2013-2015.

2017-05-05

The death rate for brain cancer, the most common cancer cause of death for children and teens aged 1-19 years, was 24% higher in males (0.73 per 100,000) than females (0.59) aged 1-19 years during 2013-2015. Death rates were higher for males than females for all age groups, but the difference did not reach statistical significance for the age group 5-9 years. Death rates caused by brain cancer were highest at ages 5-9 years (0.98 for males and 0.85 for females).

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.

To determine whether neurodevelopmental outcomes at the age of 2 years accurately predict school readiness in children who survived respiratory distress syndrome after preterm birth. Our cohort included 121 preterm infants who received surfactant and ventilation and were enrolled in a randomized controlled study of inhaled nitric oxide for respiratory distress syndrome. Abnormal outcomes at the age of 2 years were defined as neurosensory disability (cerebral palsy, blindness, or bilateral hearing loss) or delay (no neurosensory disability but Bayley Scales of Infant Development mental or performance developmental index scores <70). School readiness (assessed at a mean age of 5y 6mo, SD 1y) was determined using neurodevelopmental assessments of motor, sensory, receptive vocabulary, perceptual, conceptual, and adaptive skills. The mean birthweight of the cohort (57 males, 64 females) was 987g (SD 374), and the mean gestational age was 27.3 weeks (SD 2.6). At the age of 2 years, the neurodevelopmental classification was 'disabled' in 11% and 'delayed' in 23%. At the age of 5 years 6 months, intensive special education was required for 11% and some special education for 21%. Disability and delay at the age of 2 years were 92% and 50% predictive of lack of school readiness respectively, whereas only 15% of children who were normal at the age of 2 years were not school ready at the later assessment. Children with delay at 2 years were more likely to need special education if they were socially disadvantaged. Without preschool developmental supports, preterm survivors living in poverty will require more special education services.

Aim The aim of the present study was to identify the various background variables and its influence on behavior management problems (BMP) in children. Materials and methods The study included 165 children aged 2 to 8 years. During the initial dental visit, an experienced operator obtained each child’s background variables from accompanying guardians using a standardized questionnaire. Children’s dental behavior was rated by Frankel behavior rating scale. The behavior was then analyzed in relation to the answers of the questionnaire, and a logistic regression model was used to determine the power of the variables, separately or combined, to predict BMP. Results The logistic regression analysis considering differences in background variables between children with negative or positive behavior. Four variables turned out to be as predictors: Age, the guardian’s expectation of the child’s behavior at the dental examination, the child’s anxiety when meeting unfamiliar people, and the presence and absence of toothache. Conclusion The present study concluded that by means of simple questionnaire BMP in children may be expected if one of these attributes is found. Clinical significance Information on the origin of dental fear and uncooperative behavior in a child patient prior to treatment process may help the pediatric dentist plan appropriate behavior management and treatment strategy.

To examine the associations between cumulative physical activity (PA) and its changes over 3 years and changes over 9 years of follow-up in physical performance in older adults. Longitudinal. Community-based. Men and women aged 65 and older from the Invecchiare in Chianti study (N = 782). Physical performance was assessed at baseline and at 3-, 6-, and 9-year follow-up using the Short Physical Performance Battery (SPPB). PA was assessed through an interviewer-administered questionnaire at baseline and 3-year follow-up. Analyses were adjusted for education, body mass index, smoking, alcohol intake, coronary heart disease, stroke, peripheral arterial disease, cancer, lung disease, lower extremity osteoarthritis, depression, and Mini-Mental State Examination. Over 3 years of follow-up, 27.8% of participants were inactive, 52.2% were minimally active, and 20.0% were active, and the PA of 37.2% decreased, there was no change in PA of 50.1% and the PA of 12.7% increased. After adjustment for potential covariates, being mostly active (-1.08, 95% confidence interval (CI) = -1.43 to -0.73) and minimally active (-1.33, 95% CI = -1.53 to -1.12) over 3 years of follow-up was associated with less decline in SPPB score than being mostly inactive (-2.60, 95% CI = -2.92 to -2.27). When analyzing changes, increasing PA (-0.57, 95% CI = -1.01 to -0.12) was associated with less decline in SPPB score over 9 years than decreasing PA (-2.16, 95% CI = -2.42 to -1.89). Maintaining or increasing PA levels may attenuate age-associated physical performance decline. © 2017, Copyright the Authors Journal compilation © 2017, The American Geriatrics Society.

Exposure to some perfluoroalkyl substances (PFAS), such as perfluorohexane sulfonate (PFHxS), perfluorooctanoate (PFOA), perfluorooctane sulfonate (PFOS), and perfluorononanoic acid (PFNA), may alter levels of sex hormones and insulin-like growth factor-1 (IGF-1) in animals. Human studies on this topic are scarce, and none have been conducted in young children. We investigated the relationship between levels of PFAS and estradiol, total testosterone, and IGF-1 in 2,292 children (6-9 years of age) from the C8 Health Project who lived near a chemical plant in the Mid-Ohio Valley (USA) with local contamination from PFOA. Serum samples were collected in 2005-2006 and analyzed for PFAS, sex hormones, and IGF-1. Results from regression models were expressed as the adjusted percentage difference (95% CI) per sex-specific interquartile range (IQR) increment of each PFAS serum concentration. Analyses by PFAS quartiles were also conducted. Median concentrations of PFHxS, PFOA, PFOS, and PFNA were 8, 35, 22, and 1.7 ng/mL in boys and 7, 30, 21, and 1.7 ng/mL in girls. In boys, PFOA concentrations were significantly associated with testosterone levels (-4.9%; 95% CI: -8.7, -0.8%); PFOS with estradiol (-4.0%; 95% CI: -7.7, -0.1%), testosterone (-5.8%; 95% CI: -9.4, -2.0%), and IGF-1 (-5.9%; 95% CI: -8.3, -3.3%); and PFNA with IGF-1 (-3.5%; 95% CI: -6.0, -1.0%). In girls, significant associations were found between PFOS and testosterone (-6.6%; 95% CI: -10.1, -2.8%) and IGF-1 (-5.6%; -8.2, -2.9%); and PFNA and IGF-1 (-3.8%; 95% CI: -6.4, -1.2%). In both sexes, the magnitudes of the associations decreased monotonically across quartiles for both testosterone and IGF-1 in relation to PFOS, and for IGF-1 and PFNA in girls. To our knowledge, this is the first study suggesting that PFAS are associated with lower levels of IGF-1 and sex hormones in young children.

The aim of the study was to examine predictors of eating disorder symptoms in a population based sample at the earliest age at which they can be measured using the Children's Eating Attitudes Test. Data were collected from the longitudinal Gateshead Millennium Study cohort; 609 children participated in the 7 year data sweep (and their mothers and teachers), and 589 children participated in the 9 year data sweep. Eating disorder symptoms at 9 years were higher in boys, and in children from more deprived families. Higher eating disorder symptoms were associated with more body dissatisfaction at 9 years. Higher symptoms were predicted by higher levels of dietary restraint and of emotional symptoms, but not greater body dissatisfaction, 2 years earlier. The study showed that some correlates of high eating disorder symptoms found in adolescents and adults are also found in children, before the rise in diagnosable eating disorders over the pubertal period.

The family context plays a critical role in the health of the child. This was the first study to examine the usefulness of the General Functioning subscale of the Family Assessment Device (FAD-GF) in assessing family functioning and its relationship to internalizing symptoms in school-aged children aged between 9 and 11 years of age. Eight hundred and forty-seven year 4 and 5 students from 13 schools (607 intervention students, and 240 control students) participated in the Aussie Optimism Positive Thinking Skills Program (AO-PTS) – a universal school-based program targeting internalizing symptoms. Students rated how ‘healthy’ they perceived their family to be at pre-test and at 6-months follow-up. Although some aspects of validity and reliability could be improved, results indicated that perceptions of family functioning at pre-test were predictive of internalizing symptoms at the 6-months follow-up. The FAD-GF therefore showed promise as a potential measure of family functioning for children as young as 9 years old. Regardless of children’s pre-test levels of perceived family functioning, no intervention effects were found on the anxiety and depression scales; this finding suggests that child perceptions of family functioning may act as a general protective factor against internalizing symptomology.

Specific problems with time and timing that affect daily routines, homework, school work, and social relations have been recognized in children with ADHD. The primary treatments for children with ADHD do not specifically focus on time-related difficulties. The aim of this randomized controlled study (RCT) was to investigate how multimodal interventions, consisting of training in time-processing ability (TPA) and compensation with time-assistive devices (TAD), affect TPA and daily time management (DTM) in children with ADHD and time difficulties, compared with only educational intervention. Thirty-eight children on stable medication for ADHD in the 9-15-year age range were randomly allocated to an intervention or a control group. The children's TPA was measured with a structured assessment (KaTid), and the children's DTM was rated by a parent questionnaire (Time-Parent scale) and by children's self-reporting (Time-Self-rating). The intervention consisted of time-skill training and compensation with TAD. Data were analysed for differences in TPA and in DTM between the control and intervention groups in the 24-week follow-up. Children in the intervention group increased their TPA significantly (p = 0.019) more compared to the control group. The largest increase was in orientation to time. In addition, the parents in the intervention group rated their children's DTM as significantly (p = 0.01) improved compared with the parents in the control group. According to the children, their DTM was not significantly changed. In conclusion, a multimodal intervention consisting of time-skill training and TAD improved TPA and DTM in children with ADHD aged 9-15 years.

Previous studies with children have demonstrated inhibition difficulties associated with prematurity, but the question of potentially catching up with a delay in inhibition processes before adolescence still remains. Moreover, preterm adolescents are more at risk than their term-born peers for presenting behavioral problems such as emotional difficulties and attention deficit/hyperactivity disorder. In addition to examining response inhibition, this study addressed, for the first time, the impact of an emotional context on response inhibition abilities and its relation to behavioral problems in late school-aged preterm children. Fifty-eight preterm children aged 9-12 years were compared with 61 controls on two versions of a stop-signal task, the Delay Frustration Task, and the Strengths and Difficulties Questionnaire. Results showed general difficulties in inhibiting a response, rather than a specific impact of emotional context in preterm children. Compared with controls, these children exhibited more and longer button presses in a delay situation, as well as faster go reaction times associated with lower probability of inhibition in the stop-signal tasks. These difficulties reflected impulsivity and were associated with higher hyperactivity/inattention and conduct problems. Additionally, intrauterine growth restriction was found to be an additional perinatal risk factor for hyperactivity/inattention symptoms. These findings suggest that remaining inhibition difficulties in the preterm population at preadolescence could reveal increasing behavioral issues.

To examine the association between the age of onset and duration of parent-reported symptoms of sleep-disordered breathing (SDB) and behavioral problems at age 2. Parent-reported SDB symptoms were assessed quarterly between 3 months and 2 years among 583 Canadian Healthy Infant Longitudinal Development Edmonton-site participants. Parent-reported SDB symptoms were clustered into phenotypes using group-based trajectory analysis based on age of onset and duration of symptoms. Home-based polysomnography (PSG) was completed at 1 year. The Child Behavior Checklist preschool-version (Mean T-score 50, standard deviation 10 points) assessed total, externalizing (attention), and internalizing (anxiety, depression) behaviors at 2 years. Four phenotypes were identified: no SDB (64.7%), early-onset SDB (15.7%, peak symptoms at 9 months), late-onset (14.2%, peak symptoms at 18 months), and persistent SDB symptoms (5.3%, peak symptoms from 3 through 24 months). Persistent SDB (9.5 points, 95% CI 1.7, 17.2; p = .02) predicted the greatest magnitude of effect of total behavior problems, compared with children without SDB. Children with early-onset SDB (3.5 points, 95% CI 1.6, 5.4; p ≤ .001) and late-onset SDB (6.1 points 95% CI 4.0, 8.3; p ≤ .001) had increased total behavioral problems than children without SDB to 2 years. Additional analyses showed that the SDB phenotypes' trajectories were important for internalizing but not for externalizing behavior problems. There were no significant associations between home-PSG and parent-reported behavior problems. Findings suggest that the age of onset and duration of parent-reported SDB symptoms prior to age 2 have adverse consequences for overall behavior problems. © Sleep Research Society 2017.

Objectives To assess the prevalence and incidence of dental caries in school-aged African-American children who received semi-annual fluoride varnish applications. Methods A cohort of six-year-old high caries-risk African-American children (n=98) was recruited in Uniontown, Alabama and followed for six years. Oral examinations were done annually by three trained/calibrated dentists. Tooth surfaces with cavitated caries, missing due to caries and with filled surfaces were recorded, using WHO criteria. Also, as part of the study, children received periodic oral health instruction, fluoride varnish applications and referral to dentists starting at baseline. Results The person-level prevalence of dmfs/DMFS was: 61.2 percent at mean age 5.9 (n=98, mean dmfs/DMFS=11.6); 63.8 percent at age 6.7 (n=80, mean dmfs/DMFS=13.2); 70.6 percent at age 7.8 (n=68, mean dmfs/DMFS=14.2); 65.7 percent at age 8.8 (n=68, mean dmfs/DMFS=11.8); 55.6 percent at age 9.7 (n=63, mean dmfs/DMFS=8.8); 40.3 percent at age 10.7 (n=62, mean dmfs/DMFS=3.4); and 37.1 percent at age 11.7 (n=62, mean dmfs/DMFS=2.3). The six-year person-level incidence of dmfs/DMFS was 32.3 percent (mean dmfs/DMFS=1.6) from age 5.9 to age 11.7 (n=62). Conclusion In spite of the oral health education and fluoride varnish applications, there was substantial new dental caries in this high-risk sample. Additional studies evaluating risk factors for caries development are ongoing. PMID:27306247

Background Teens who give birth at age 15–17 years are at increased risk for adverse medical and social outcomes of teen pregnancy. Methods To examine trends in the rate and proportion of births to teens aged 15–19 years that were to teens aged 15–17 years, CDC analyzed 1991–2012 National Vital Statistics System data. National Survey of Family Growth (NSFG) data from 2006–2010 were used to examine sexual experience, contraceptive use, and receipt of prevention opportunities among female teens aged 15–17 years. Results During 1991–2012, the rate of births per 1,000 teens declined from 17.9 to 5.4 for teens aged 15 years, 36.9 to 12.9 for those aged 16 years, and 60.6 to 23.7 for those aged 17 years. In 2012, the birth rate per 1,000 teens aged 15–17 years was higher for Hispanics (25.5), non-Hispanic blacks (21.9), and American Indians/Alaska Natives (17.0) compared with non-Hispanic whites (8.4) and Asians/Pacific Islanders (4.1). The rate also varied by state, ranging from 6.2 per 1,000 teens aged 15–17 years in New Hampshire to 29.0 in the District of Columbia. In 2012, there were 86,423 births to teens aged 15–17 years, accounting for 28% of all births to teens aged 15–19 years. This percentage declined from 36% in 1991 to 28% in 2012 (p<0.001). NSFG data for 2006–2010 indicate that although 91% of female teens aged 15–17 years received formal sex education on birth control or how to say no to sex, 24% had not spoken with parents about either topic; among sexually experienced female teens, 83% reported no formal sex education before first sex. Among currently sexually active female teens (those who had sex within 3 months of the survey) aged 15–17 years, 58% used clinical birth control services in the past 12 months, and 92% used contraception at last sex; however, only 1% used the most effective reversible contraceptive methods. Conclusions Births to teens aged 15–17 years have declined but still account for approximately one

Are Recommended Doses of Acetaminophen Effective for Children Aged 2 to 3 Years? A Pharmacokinetic Modeling Answer.

Acetaminophen (APAP) elixir is a widely used pediatric antipyretic medication. It has been shown that up to 30% of febrile children presenting to a large urban pediatric emergency department received inadequate APAP dosages at home with errors primarily due to age-based dosing. Parental education material in the form of weight-based dosing guides has been proposed; however, validation of current recommended APAP dosages using pharmacokinetic models is needed. This study used a mathematical model of APAP absorption to predict plasma concentrations and to compare them with the range required to reach and achieve antipyresis (10-20 μg/mL). A common APAP preparation (Children's Tylenol Elixir) was tested (children aged 2-3 years, 10.9-15.9 kg). The manufacturer's suggested dose of 160 mg was compared with the standard 10 to 15 mg/kg dose range. The model predicts a peak plasma concentration between 6.38 and 8.55 μg/mL for 10 mg/kg dose and 9.57 and 12.8 μg/mL for 15 mg/kg dose. The manufacturer's suggested dose of 160 mg was tested across the limits of the weight range (10.9-15.9 kg). A peak plasma concentration between 9.36 and 12.6 μg/mL was found for the lower weight limit (10.9 kg child) and 6.42 to 8.61 μg/mL for the upper weight limit (15.9 kg child). With the use of this model, the 10 mg/kg dose does not reach the plasma concentration value for antipyresis (10-20 μg/mL), whereas 15 mg/kg is adequate only if assuming a greater absorption constant. The 160 mg dose is effective only for children weighing 10.9 kg. Individual differences in drug bioavailability, volume of distribution, and absorption/elimination constants undoubtedly exist, and future studies directly measuring plasma APAP concentration and pharmacokinetics are needed. However, these results indicate that dosages for APAP in children should be weight based and manufacturers should review their dosing recommendations.

This study aimed to identify the prevalence and factors associated with body mass index (BMI) in children aged 9-11 years. The study is part of the International Study of Childhood Obesity Lifestyle and the Environment (ISCOLE). Body composition was determined using the bipolar bioimpedance technique. The mean BMI value was categorized as recommended by the World Health Organization. For seven consecutive days, participants used an accelerometer to objectively monitor sedentary behavior (SB) and moderate to vigorous physical activity. Individual factors (anthropometric and behavioral), family aspects, and family and school environment were provided by participants and parents and were analyzed by multilevel linear regression adjusted for gender, ethnicity, school, number of siblings, and total annual family income. The mean BMI was 20.1kg/m 2 , and 51.8% of the children were overweight/obese (50.3% boys, 53.4% girls, p=0.014). Considering all participants, the associated factors of BMI were body fat percentage (BF%, β=0.0216, p<0.001) and screen time (ST, β=0.0050, p=0.006). In boys, the associated factors were BF% (β=0.0209, p<0.001), ST (β=0.006, p=0.036), and healthy eating policies or practices (β=0.0276, p=0.025). In girls, only BF% was associated (β=0.0221, p<0.001) with BMI. High prevalence of overweight/obesity was observed in children from São Caetano do Sul. Different associated factors were identified between the genders, with only BF% being common in both genders. Copyright © 2017 Sociedade Brasileira de Pediatria. Published by Elsevier Editora Ltda.

The purpose of this study was to examine the test-retest reliability and construct validity of three age-adapted Yo-Yo intermittent tests in football players aged 9-16 years (n = 70) and in age-matched non-sports active boys (n = 72). Within 7 days, each participant performed two repetitions of an age-related intensity-adapted Yo-Yo intermittent test, i.e. the Yo-Yo intermittent recovery level 1 children's test for 9- to 11-year-olds; the Yo-Yo intermittent endurance level 1 for 12- to 13-year-olds and the Yo-Yo intermittent endurance level 2 test for 14- to 16-year-olds. Peak heart rate (HRpeak) was determined for all tests. The distance covered in the tests was 57% (1098 ± 680 vs. 700 ± 272 m), 119% (2325 ± 778 vs. 1062 ± 285 m) and 238% (1743 ± 460 vs. 515 ± 113 m) higher (p ≤ .016), respectively for football-trained than for non-sports active boys aged 9-11, 12-13 and 14-16 years. The typical errors of measurement for Yo-Yo distance, expressed as a percentage of the coefficient of variation (confidence interval), were 11.1% (9.0-14.7%), 10.1% (8.1-13.7%) and 8.5% (6.7-11.7%) for football players aged 9-11, 12-13 and 14-16 years, respectively, with corresponding values of 9.3% (7.4-12.8%), 10.2% (8.1-14.0%) and 8.5% (6.8-11.3%) for non-sports active boys. Intraclass correlation coefficient values for test-retest were excellent in both groups (range: 0.844-0.981). Relative HRpeak did not differ significantly between the groups in test and retest. In conclusion, Yo-Yo intermittent test performances and HRpeak are reliable for 9- to 16-year-old footballers and non-sports active boys. Additionally, performances of the three Yo-Yo tests were seemingly better for football-trained than for non-sports active boys, providing evidence of construct validity.

Two doses of measles vaccine (MV) might reduce the nonmeasles mortality rate more than 1 dose of MV does. The effect of 2 versus 1 dose on morbidity has not been examined. Within a randomized trial of the effect of 2 doses versus 1 dose of MV on mortality in Guinea-Bissau, we investigated the effect on hospital admissions. Children were randomly assigned 1:2 to receive MV at 4.5 and 9 months of age or the currently recommended dose at 9 months. We compared hospital admission rates among children between 9 and 18 months of age in a Cox regression model with age as the underlying time scale. Half of the children had received neonatal vitamin A supplementation (NVAS) in another trial. The beneficial effect of MV at 4.5 and 9 months on mortality was limited to children who had not received NVAS; therefore, we investigated the interaction of MV with NVAS on admission rates. Among 5626 children (2 doses of MV, 1960 children; 1 dose of MV, 3666), we identified 311 hospital admissions of children between 9 and 18 months of age. Overall, compared to 1 dose of MV, 2 doses reduced the risk of hospital admission for children who had not received NVAS (hazard ratio [HR], 0.66 [95% confidence interval (CI), 0.47-0.93]), but we found no effect among NVAS recipients (HR, 1.16 [95% CI, 0.82-1.63]) (P = .02 for interaction). The benefit of 2 doses of MV was limited to children who had not received NVAS. NVAS is not generally recommended; hence, an early 2-dose measles vaccination policy might reduce hospital admissions more than the current policy of providing the first MV at 9 months of age.

To examine mean level differences and longitudinal and reciprocal relations among behavioral sleep problems, emotional dysregulation, and attentional regulation across early childhood for children with and without attention-deficit hyperactivity disorder (ADHD) at 8 to 9 years. This study used data from Growing Up in Australia: The Longitudinal Study of Australian Children (LSAC)-Infant Cohort (n = 4,109 analyzed). Children with and without ADHD were identified at age 8 to 9 years via parent report of ADHD diagnosis and the 5-item Inattention-Hyperactivity subscale from the Strengths and Difficulties Questionnaire. Maternal report of child sleep problems and self-regulation was collected at 0 to 1, 2 to 3, 4 to 5, and 6 to 7 years of age. Analysis of variance was used to compare mean level differences in sleep problems and emotional and attentional regulation by ADHD group. Longitudinal structural equation modeling examined the relations among sleep and self-regulation across time in children with and without ADHD. Children with ADHD had persistently elevated levels of sleep problems (from infancy) and emotional and attentional dysregulation compared to controls (from 2 to 3 years of age). Sleep problems, emotional dysregulation, and attentional regulation were stable over time for both groups. Sleep problems were associated with greater emotional dysregulation 2 years later from 2 to 3 years of age for both groups, which in turn was associated with poorer attentional regulation. There was no direct relationship between sleep problems and later attentional regulation. Sleep problems in children with and without ADHD are associated with emotional dysregulation, which in turn contributes to poorer attentional functioning. This study highlights the importance of assessing and managing sleep problems in young children.

The aim of this study was to provide detailed information concerning clinically relevant occlusal traits and the prevalence of occlusal anomalies in an orthodontically relevant period of dental development. Four hundred and ninety-four German schoolchildren (237 males and 257 females), median age 9 years, were orthodontically examined. Overjet and overbite were measured to the nearest 0.5 mm, and sagittal molar relationships were registered clinically to the nearest quarter unit. In addition, crossbites, scissor bites, and midline displacements were evaluated. Descriptive statistics was complemented by testing gender differences and differences between groups with Class I and Class II anomalies (Mann-Whitney U-test) as well as a statistical evaluation of differences between the three dental stages (Kruskal-Wallis test). Overjet exhibited an extreme range between -2 and 12 mm (median values 3-3.5 mm). An increased overjet was more prevalent than a reduced or reverse overjet, and a severely increased overjet greater than 6 mm was a common finding affecting around 5-10 per cent of the children. Similarly, overbite showed considerable variations of between -1 and 9 mm (medians 3-3.5 mm) and males exhibited a significantly larger overbite than females. In Class II malocclusion subjects, overbite was significantly enlarged (on average between 0.5 and 1 mm) when compared with those with a Class I malocclusion. Traumatic contact of the gingiva affected every 14th child. A Class II molar relationship of three-quarter units or more was a frequent finding affecting more than one child in five. In addition, at 9 years of age, 3 per cent of the children exhibited a Class III molar relationship of at least a half unit. The wide range of orthodontically relevant occlusal traits found in the present study underlines the need for orthodontic screening at 9 years of age (or earlier).

We analysed at what age parents start complementary food in very low birth weight infants, determined risk factors for early introduction of complementary food (post-term age) and analysed whether the age at introduction of complementary food influences height or weight at 2 years of age. Parents of premature infants born in 2009-2011 answered questionnaires regarding introduction of complementary food in the first year of life (N=2262) and were followed up at a post-term age of 2 years (N=981). Length and weight were compared with full-term infants from the KiGGs study. Logistic and linear regression analyses were conducted to study predictors for early introduction of complementary food and the influence of age at introduction of complementary food on later height and weight. Average age at introduction of complementary food was 3.5 months post-term age. The lower the gestational age at birth, the earlier (post-term age) vegetables and meat were introduced. Age at introduction of complementary food was influenced by intrauterine growth restriction, gestational age at birth, maternal education and a developmental delay perceived by the parents. Length and weight at a post-term age of 2 years was not negatively influenced by early introduction of complementary food. VLBW infants are introduced to complementary food on average before a post-term age of 4 months. There was no negative effect of early introduction of complementary food on height and weight at 2 years of age.

Both short sleep duration and sleep-disordered breathing (SDB) are associated with poor neurocognitive development. However, the co-contributions of short sleep duration and SDB on neurodevelopment in pre-school children are relatively unknown. We assessed both sleep duration and SDB by quarterly questionnaire from three months to two years of age among Canadian Healthy Infant Longitudinal Development (CHILD) birth cohort participants. Group-based modeling determined trajectories of total, daytime, and nighttime sleep duration and SDB. Linear regression was used to assess the impact of sleep duration and SDB trajectories on cognitive (primary outcome) and language (secondary) development at two years of age as assessed by the Bayley Scale of Infant Development (BSID-III) (mean 100; standard deviation of 15). Of the 822 CHILD Edmonton participants, 703 (86%) were still enrolled at two years of age with 593 having BSID-III data at two years of age. Trajectory analysis identified four total sleep durations phenotypes [short sleepers (17.9%), decline to short sleepers (21.1%), intermediate sleepers (36.9%) and long sleepers (24.1%)]. Compared to children with intermediate sleep durations, short sleepers had a 5.2-point lower cognitive development score at two years of age [standard error (SE) 1.7; p = 0.002]. Nocturnal sleep duration, compared to daytime sleep duration had the greatest effect on cognitive development. We also identified three SDB symptom trajectories [early-onset SDB (15.7%), late-onset SDB (14.2%), and persistent SDB (5.3%)] and 79.5% of children had no SDB symptoms. Children with persistent SDB also had a 5.3-point lower language score (SE 2.7; p = 0.05) compared to children with no SDB. SDB trajectories were not associated with cognitive development. In a population-representative birth cohort study, both short sleep duration and SDB were associated with adverse neurodevelopment at two years of age. Children with short nighttime sleep

Statement of the Problem: Dental caries in infants and young children is prevalent worldwide; its magnitude and associated factors vary between communities because of cultural and social economic differences. No such information was available for pre-school children in Mbeya city. Purpose: To determine dental caries status and associated factors in 2 to 4-year-old children in Mbeya city. Materials and Method: A cross sectional study was conducted among 525 children aged 2-4 years and their parents/caregivers. Caries was assessed using caries assessment spectrum and treatment index, oral hygiene by visual inspection for visible plaque on index teeth, and dietary and oral hygiene habits by a questionnaire. Kappa statistics was used to test reliability of study instruments, χ2-test and logistic regression was employed for studying associations. Results: Caries free children for dmft1, dmft2 and dmft3 were 79.8%, 83.8% and 94.7% and caries experience was 0.49 (1.23), 0.4 (1.14) and 0.10 (0.53) respectively. Older age [(OR =2.722 (1.617-4.582) p=< 0.001)]; and frequent consumption of factory made sugary foods/snacks at age 1-2 years [(OR=3.061 (1.188-7.887) p=0.021] were associated with caries. Prolonged breastfeeding for more than 1 year and breastfeeding at night had no association with dental caries. Conclusion: The prevalence of dental caries was very low. Older age and frequent consumption of factory made sugary foods at age 1-2 years were associated with higher odds of developing dental caries. Prolonged breasfeeding and breastfeeding at night had no association with dental caries. Prevention of dental caries should be instituted as soon as primary teeth start erupting, especially through discouraging consumption of factory made sugary foods/snacks. PMID:28620634

Human papillomavirus (HPV) infections cause anogenital cancers and warts. The 9-valent HPV vaccine provides protection against 7 high-risk types of HPV responsible for 90% of cervical cancers and 2 other HPV types accounting for 90% of genital warts. To determine whether HPV type-specific antibody responses would be noninferior among girls and boys aged 9 to 14 years after receiving 2 doses of the 9-valent HPV vaccine compared with adolescent girls and young women aged 16 to 26 years receiving 3 doses. Open-label, noninferiority, immunogenicity trial conducted at 52 ambulatory care sites in 15 countries. The study was initiated on December 16, 2013, with the last participant visit for this report on June 19, 2015. Five cohorts were enrolled: (1) girls aged 9 to 14 years to receive 2 doses 6 months apart (n = 301); (2) boys aged 9 to 14 years to receive 2 doses 6 months apart (n = 301); (3) girls and boys aged 9 to 14 years to receive 2 doses 12 months apart (n = 301); (4) girls aged 9 to 14 years to receive 3 doses over 6 months (n = 301); and (5) a control group of adolescent girls and young women aged 16 to 26 years to receive 3 doses over 6 months (n = 314). Two doses of the 9-valent HPV vaccine administered 6 or 12 months apart or 3 doses administered over 6 months. The primary end point was prespecified as the antibody response against each HPV type assessed 1 month after the last dose using a competitive immunoassay. Each of the three 2-dose regimens was compared with the standard 3-dose schedule in adolescent girls and young women using a noninferiority margin of 0.67 for the ratio of the antibody geometric mean titers. Of the 1518 participants (753 girls [mean age, 11.4 years]; 451 boys [mean age, 11.5 years]; and 314 adolescent girls and young women [mean age, 21.0 years]), 1474 completed the study and data from 1377 were analyzed. At 4 weeks after the last dose, HPV antibody responses in girls and boys given 2 doses were noninferior to

A trial involving adults 50 years of age or older (ZOE-50) showed that the herpes zoster subunit vaccine (HZ/su) containing recombinant varicella-zoster virus glycoprotein E and the AS01B adjuvant system was associated with a risk of herpes zoster that was 97.2% lower than that associated with placebo. A second trial was performed concurrently at the same sites and examined the safety and efficacy of HZ/su in adults 70 years of age or older (ZOE-70). This randomized, placebo-controlled, phase 3 trial was conducted in 18 countries and involved adults 70 years of age or older. Participants received two doses of HZ/su or placebo (assigned in a 1:1 ratio) administered intramuscularly 2 months apart. Vaccine efficacy against herpes zoster and postherpetic neuralgia was assessed in participants from ZOE-70 and in participants pooled from ZOE-70 and ZOE-50. In ZOE-70, 13,900 participants who could be evaluated (mean age, 75.6 years) received either HZ/su (6950 participants) or placebo (6950 participants). During a mean follow-up period of 3.7 years, herpes zoster occurred in 23 HZ/su recipients and in 223 placebo recipients (0.9 vs. 9.2 per 1000 person-years). Vaccine efficacy against herpes zoster was 89.8% (95% confidence interval [CI], 84.2 to 93.7; P<0.001) and was similar in participants 70 to 79 years of age (90.0%) and participants 80 years of age or older (89.1%). In pooled analyses of data from participants 70 years of age or older in ZOE-50 and ZOE-70 (16,596 participants), vaccine efficacy against herpes zoster was 91.3% (95% CI, 86.8 to 94.5; P<0.001), and vaccine efficacy against postherpetic neuralgia was 88.8% (95% CI, 68.7 to 97.1; P<0.001). Solicited reports of injection-site and systemic reactions within 7 days after injection were more frequent among HZ/su recipients than among placebo recipients (79.0% vs. 29.5%). Serious adverse events, potential immune-mediated diseases, and deaths occurred with similar frequencies in the two study groups. In our

The aim of this study was to assess peri-operative complications, safety and efficacy of non-cemented femoral fixation in total hip arthroplasty (THA) as compared to cemented femoral fixation in the elderly population. Fifty-two matched pair analysis of patients with 75 years of age and older (104 patients), who underwent primary THA from June 1997 to December 2004, was performed based on age, sex, BMI, and Charnley classification. Mean age was 81 years (75-101) and the average follow up was 3.1 ± 2.9 years (1.2-6.4). There was no difference in peri-operative cardiopulmonary complications, pulmonary failures, deep venous thrombosis, pulmonary embolus, length of stay, or discharge deposition between the two groups. Non-cemented fixation is safe and effective in patients older than 75 years of age. Copyright © 2013 Elsevier Inc. All rights reserved.

We evaluated the associations of teenage insulin and adolescent diet with 10-year weight gain in an analysis sample of black and white girls matched for pubertal stage, body mass index (BMI) (or fat mass), and insulin at ages 9 to 10 years. We hypothesized that preteen insulin and insulin resistance would interact with dietary factors to positively predict increases in BMI. Furthermore, we hypothesized that increased insulin and insulin resistance, interacting with higher caloric intake during adolescence, would lead to greater increments in BMI in black girls than in white girls. Prospective 10-year follow-up was performed on 215 pairs of black and white schoolgirls matched at baseline by BMI (or fat mass), insulin, and pubertal stage, with repeated measures of body habitus, insulin, and dietary intake. When matched for BMI, black girls had higher fat-free mass and white girls had higher fat mass at ages 9 to 10 years. Black-white differences in caloric intake were not significant at ages 9 to 10 years, but black girls consumed more calories at age 19 years. Black girls consumed a greater percentage of calories from fat throughout. At age 19 years, black girls had higher BMI, fat mass index, and insulin. When matched at ages 9 to 10 years for fat mass, black girls were heavier, had higher BMI, and had greater fat-free mass. By ages 18 to 19 years, black girls continued to have higher BMI, but had accrued higher fat mass and a higher percentage of body fat. By stepwise multiple regression, 10-year increases in BMI were predicted by ages 9 to 10 years BMI, 10-year change in insulin, and a 3-way interaction between ages 9 to 10 years insulin, adolescent caloric intake, and race (higher in black girls) (all Ps < .0001). Insulin at ages 9 to 10 years interacts with caloric intake to increase BMI by age 19 years. There appear to be intrinsic black-white metabolic differences that lead to greater gains in fat during adolescence in black girls. Evaluating BMI and insulin

Awareness has been an important factor in theories of onset and development of stuttering. So far it has been suggested that even young children might be aware of their speech difficulty. The purpose of the present study was to investigate (a) the number of stuttering children aware of their speech difficulty, (b) the description of reported behavioural expression of awareness, (c) the relationship with age-related variables and with stuttering severity. For a total group of 1122 children with mean age of 4 year 7 months (range 2-7 years old), parental-reported unambiguous verbal and non-verbal reactions as a response to stuttering were available. In the present study, awareness is observed for 56.7% of the very young children (i.e., 2 years old) and gradually increases with age up until 89.7% of the children at the age of seven. All considered age-related factors (i.e., chronological age, age at onset and time since onset) and stuttering severity are statistically significantly related to awareness. Readers will be able to: (1) Describe findings of awareness of speech disfluency of stuttering children based on an overview of literature; (2) Describe methodological aspects of studies on awareness; (3) Know reported data on awareness of speech disfluency in young stuttering children of the present study; (4) Describe the relationship of awareness of speech disfluency with chronological age, age at onset, time since onset, gender and stuttering severity.

The aim of this retrospective cohort study was to investigate the association between the use of fluoride tablets among users of fluoridated salt and the occurrence of caries and fluorosis. We examined 583 school children aged 6-9 years in Berlin, Germany for caries-status (modified defs > or = 1; d(3)-level) and fluorosis occurrence on central incisors (TSIF > or = 1). Parents completed questionnaires about several sociodemographic and oral health related factors of the previous years. To adjust for confounding, we used log-risk regression and estimated relative risks (RR) and 95% confidence intervals. The mean modified defs was 3.2 (SD = 5.9) and 58% children were caries-free. Twenty-two per cent of the children revealed mild fluorosis (TSIF 1 and 2). Length of fluoride tablet use was inversely associated (adjusted for age and SES) with caries-status: 2-4 years: RR = 0.8, 95%CI: 0.7-1.0, > or =5 years: RR = 0.5, 95%CI 0.3-0.7 (reference: 0-1 year use). This inverse association could mainly be observed in children who consumed fluoridated salt as well. Relative risks for mild fluorosis were 1.8 (95%CI: 1.1-2.9) and 2.7 (95%CI: 1.6-4.5) for fluoride tablet use of 2-4 years and > or =5 years, respectively compared with 0-1 year use. Fluoride tablets seem to be effective in reducing the occurrence of caries in children with low caries levels in particular among those using fluoridated salt as well. However, fluoride tablets increase the occurrence of mild fluorosis in permanent incisors.

Despite improvements in child passenger safety legislation and equipment, motor vehicle crashes (MVCs) continue to be the leading cause of death in children younger than 10 years. The objective of this study was to describe factors associated with restraint use in fatal MVC in children 0 year to 9 years old. The Fatality Analysis Reporting System, maintained by the National Highway Transportation Safety Administration, was used to obtain data on MVC fatalities from 2001 to 2010 in children 0 year to 9 years old. The main outcome was restraint use. Demographic information (age, sex, and race) and crash characteristics including vehicle type (sedan, van, truck, sports utility vehicle) and seat position in the vehicle were analyzed with the χ statistic to evaluate these factors for any restraint use compared with no restraint use in MVC fatalities. There were 7,625 MVC fatalities in children 0 year to 9 years old from 2001 to 2010.Among these fatalities, 4,041 (53%) had any restraint use. Front seat passengers accounted for 20.9% (1,595 of 7,625) of the fatalities. Children 0 year to 3 years old had a higher proportion of restraint use than children 4 years to 9 years old (p < 0.001). White children compared with black children had higher use of restraints (p < 0.001). Children riding in sedans/vans compared with sport utility vehicles/trucks and those riding in the rear seats of the vehicle compared with those in front seats were significantly more likely to use restraints (p < 0.001). Overall, only half of children 0 year to 9 years old who died in an MVC were wearing any child restraint in the vehicle, and 20% were sitting in the front seat. Continued efforts must be made to enforce legislation and educate the public about best practices regarding child passenger safety to improve proper restraint use and to decrease MVC fatalities in children.

Intussusception (IS) is a form of acute intestinal obstruction that occurs mainly in infants and is usually of unknown cause. An association between IS and the first licensed rotavirus vaccine, a reassortant-tetravalent, rhesus-based rotavirus vaccine (RRV-TV), led to the withdrawal of the vaccine. New rotavirus vaccines have now been developed and extensively studied for their potential association with IS. This study aimed to describe the epidemiology and to estimate the incidence of IS in Latin American infants prior to new vaccine introduction. Children under 2 years of age representing potential IS cases were enrolled in 16 centers in 11 Latin American countries from January 2003 to May 2005. IS cases were classified as definite, probable, possible or suspected as stated on the Brighton Collaboration Working Group guidelines. From 517 potential cases identified, 476 (92%) cases were classified as definite, 21 probable, 10 possible and 10 suspected for intussusception. Among the 476 definite IS cases, the median age at presentation was 6.4 months with 89% of cases aged <1 year. The male to female ratio was 1.5:1. The incidence of definite IS per 100,000 subject-years ranged from 1.9 in Brazil to 62.4 in Argentina for children <2 years of age, and from 3.8 in Brazil to 105.3 in Argentina for children aged <1 year. Median hospital stay was 4 days with a high prevalence of surgery as the primary treatment (65%). Most cases (88%) made a complete recovery, but 13 (3%) died. No clear seasonal pattern of IS cases emerged. This study describes the epidemiology and estimates the incidence of IS in Latin American infants prior to the introduction of new rotavirus vaccines. The incidence of IS was found to vary between different countries, as observed in previous studies. Clinical study identifier 999910/204 (SERO-EPI-IS-204).

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.

The objective of the study was to analyze the quality of life six months after stroke in survivors under sixty years of age, to determine which life activities was the most affected, as well as to correlate the neurological insufficiency and the quality of life. It monitored 200 stroke survivors under sixty years of age treated at the Department of Neurology, University Clinical Centre Tuzla. Average age was 51,83 years (+/-7,02). The ischemic stroke was diagnosed in 77,5% stroke survivors, cerebral hemorrhage in 15%, and subarachnoid hemorrhage in 7,5%. Five stroke survivors suffered hemiplegia (2,5%), 24 (12%) experienced moderate consequences and 143 (71,5%) had mild consequences. No neurological deficit had 28 (14%) stroke survivors. Six months after the onset of disease all stroke survivors have been followed-up and evaluated about quality of life by filling in a modified questionnaire: Questionnaire on Quality of Life after Stroke (2). The questionnaire contained 20 questions covering four fields of life: Working Ability, Home Activity, Family Relations and Leisure Activities. Six months after the onset of stroke a worse quality of life in comparison to the period before the disease was noted in 172 (86%) stroke survivors, the unchanged in 19 (9,5%) and better in 9 (4,5%). The most affected is the field "Leisure Activities", followed by "Family Relations", "Home Activity", and the least affected is "Work Ability". The neurological deficit significantly correlates to the "Home Activities" and "Leisure Activities".

Exposure to perfluoroalkyl substances (PFASs) may impact children's neurodevelopment. To examine the association of prenatal and early childhood serum PFAS concentrations with children's reading skills at ages 5 and 8years. We used data from 167 mother-child pairs recruited during pregnancy (2003-2006) in Cincinnati, OH, quantified prenatal serum PFAS concentrations at 16±3weeks of gestation and childhood sera at ages 3 and 8years. We assessed children's reading skills using Woodcock-Johnson Tests of Achievement III at age 5years and Wide Range Achievement Test-4 at age 8years. We used general linear regression to quantify the covariate-adjusted associations between natural log-transformed PFAS concentrations and reading skills, and used multiple informant model to identify the potential windows of susceptibility. Median serum PFASs concentrations were PFOS>PFOA>PFHxS>PFNA in prenatal, 3-year, and 8-year children. The covariate-adjusted general linear regression identified positive associations between serum PFOA, PFOS and PFNA concentrations and children's reading scores at ages 5 and 8years, but no association between any PFHxS concentration and reading skills. The multiple informant model showed: a) Prenatal PFOA was positively associated with higher children's scores in Reading Composite (β: 4.0, 95% CI: 0.6, 7.4 per a natural log unit increase in exposure) and Sentence Comprehension (β: 4.2, 95% CI: 0.5, 8.0) at age 8years; b) 3-year PFOA was positively associated with higher children's scores in Brief Reading (β: 7.3, 95% CI: 0.9, 13.8), Letter Word Identification (β: 6.6, 95% CI: 1.1, 12.0), and Passage Comprehension (β: 5.9, 95% CI: 1.5, 10.2) at age 5years; c) 8-year PFOA was positively associated with higher children's Word Reading scores (β: 5.8, 95% CI: 0.8, 10.7) at age 8years. Prenatal PFOS and PFNA were positively associated with children's reading abilities at age 5years, but not at age 8years; 3-year PFOS and PFNA were positively associated

This study describes trends in dietary diversity and food intake over 12 years according to age at first participation in the study. Prospective cohort study. The National Institute for Longevity Sciences - Longitudinal Study of Aging, a community-based study. Participants included 922 men and 879 women who participated in the first study-wave (age, 40-79 years) and also participated in at least one study-wave from the second to seventh study-wave. Study-waves were conducted biennially. Dietary intake was calculated from 3-day dietary records with photographs. Dietary diversity was determined using the Quantitative Index for Dietary Diversity based on food intake. A mixed-effects model was used to estimate linear changes in dietary diversity and food intake over 12 years according to age at first study-wave. Mean (standard deviation (SD)) follow-up time and number of study-wave visits were 9.5 (3.7) years and 5.4 (1.8), respectively. Mean (SD, range) dietary diversity score was 0.86 (0.06, 0.52-0.96) in men and 0.88 (0.04, 0.66-0.96) in women, respectively. Fixed effects for interactions of age and time with dietary diversity score were statistically significant (p<0.05). The slope of dietary diversity among men aged 40 to 55 years increased (40-year-old slope = 0.00093/year, p<0.01; 55-year-old slope = 0.00035/year, p=0.04), with a decreasing trend started at 65 years old, although this trend was not significant (65-year-old slope = -0.00003/year, p=0.88; 79-year-old slope = -0.00057/year, p=0.21). The slope of dietary diversity among women aged 40 to 44 years increased (40-year-old slope = 0.00053/year, p=0.02; 44-year-old slope = 0.00038/year, p=0.04), whereas the slope of dietary diversity among women aged 63 to 79 years decreased (63-year-old slope = -0.00033/year, p=0.03; 79-year-old slope = -0.00092/year, p<0.001). Fruit, milk and dairy intake decreased in men around their 60s; milk and dairy intake decreased in women around their 50s; and beans and fruit

Rheumatic heart disease (RHD) is considered a major public health problem in developing countries, although scarce data are available to substantiate this. Here we quantify mortality from RHD in Fiji during 2008-2012 in people aged 5-69 years. Using 1,773,999 records derived from multiple sources of routine clinical and administrative data, we used probabilistic record-linkage to define a cohort of 2,619 persons diagnosed with RHD, observed for all-cause mortality over 11,538 person-years. Using relative survival methods, we estimated there were 378 RHD-attributable deaths, almost half of which occurred before age 40 years. Using census data as the denominator, we calculated there were 9.9 deaths (95% CI 9.8-10.0) and 331 years of life-lost (YLL, 95% CI 330.4-331.5) due to RHD per 100,000 person-years, standardised to the portion of the WHO World Standard Population aged 0-69 years. Valuing life using Fiji's per-capita gross domestic product, we estimated these deaths cost United States Dollar $6,077,431 annually. Compared to vital registration data for 2011-2012, we calculated there were 1.6-times more RHD-attributable deaths than the number reported, and found our estimate of RHD mortality exceeded all but the five leading reported causes of premature death, based on collapsed underlying cause-of-death diagnoses. Rheumatic heart disease is a leading cause of premature death as well as an important economic burden in this setting. Age-standardised death rates are more than twice those reported in current global estimates. Linkage of routine data provides an efficient tool to better define the epidemiology of neglected diseases.

More information is needed on "low-risk" preterm infants' neurological outcome so that they can be included in follow-up programs. A prospective study was performed to examine the regional brain volume changes compared to term children and to assess the relationship between the regional brain volumes to cognitive outcome of the low-risk preterm children at 9 years of age. Subjects comprised 22 preterm children who were determined to be at low risk for neurodevelopmental deficits with a gestational age between 28 and 33 weeks without a major neonatal morbidity in the neonatal period and 24 age-matched term control children term and matched for age, sex, and parental educational and occupational status. Regional volumetric analysis was performed for cerebellum, hippocampus, and corpus callosum area. Cognitive outcomes of both preterm and control subjects were assessed by Weschler Intelligence Scale for Children Revised (Turkish version), and attention and executive functions were assessed by Wisconsin Card Sorting Test and Stroop Test TBAG version. Low-risk preterm children showed regional brain volume reduction in cerebellum, hippocampus, and corpus callosum area and achieved statistical significance when compared with term control. When the groups were compared for all WISC-R subscale scores, preterm children at low risk had significantly lower scores on information, vocabulary, similarities, arithmetics, picture completion, block design, object assembly, and coding compared to children born at term. Preterm and term groups were compared on the Stroop Test for mistakes and corrections made on each card, the time spent for completing each card, and total mistakes and corrections. In the preterm group, we found a positive correlation between regional volumes with IQ, attention, and executive function scores. Additionally, a significant correlation was found between cerebellar volume and attention and executive function scores in the preterm group. Low-risk preterm

Atrial septal defect type II (ASD), according to current standards, is closed percutaneously usually after the child has reached the age of 4-5 years. There are limited data regarding such treatment in smaller infants. To evaluate feasibility, safety and efficacy of percutaneous ASD closure in children under 3 years of age. Overall group of 149 children < 3 years with hemodynamically significant ASD, who underwent effective transcatheter ASD closure in one tertiary center between 1999 and 2014 were included. Mean procedural age of treated children was 2,2 years and weight 12,5 kg. In all nitinol wire mesh devices were applied (mostly Amplatzer Septal Occluders). ASD was closed by standard technique (except few cases when left disc of implant was inserted initially into right pulmonary vein to prevent oblique position of the device). Complications related to the procedure were divided into major and minor ones. There were 97 children with a single ASD and 52 with double/multiple ASD. No death, no implant embolization, and one major complications occurred during procedure and in follow-up. ASD was completely closed in all but 8 patients with double/multiple ASD. Right ventricle diameter normalization occurred in all during 1 year follow-up. In majority of the patients in follow-up an acceleration of physical development and resolution of accompanying morbidity was observed. Percutaneous ASD device closure can be performer safely in children below 3 years of age with low risk of complication during and after the procedure.

Cross-sectional and clinical measurement. Assessment of hand function considers an essential part in clinical practice. To develop normative values of hand grip strength and dexterity function for 6-12-year-old children in Saudi Arabia. Grip strength and dexterity function was measured in 525 children using Grip Track hand dynamometer (JTECH Medical, Midvale, UT, USA) and 9-hole pegboard test respectively. The grip strength and dexterity function was improved as age progressed regardless of gender. Across all age groups, the hand grip strength of boys was significantly higher than girls for dominant hand (31.75 ± 10.33 vs 28.24 ± 9.35; P < .001) and nondominant hand (31.01 ± 10.27 vs 27.27 ± 9.30; P < .001). The girls performed slightly faster than boys for dominant hand (19.70 vs 20.68; P < .05) and nondominant hand (21.79 vs 23.46; P < .05). In general, girls completed a 9-HPT faster than boys in the 2 of 7 age groups: 11 years (9-HPT scores = 2.10 seconds; P < .01) and 12 years (9-HPT scores = 1.93 seconds; P < .01). The overall patterns of hand grip strength and dexterity function observed in the present study are similar to the previous studies that established acceleration of grip strength with advanced age, and faster performance scores in older children than younger children in both genders. Norms of hand grip strength and dexterity enable therapists to identify some developmental characteristics of hand function among Saudi children, determine the presence of impairment, and compare scores from children in different clinical settings.

Humeral retroversion physiologically decreases during growth. However, in throwing athletes, the external forces caused by repetitive throwing are thought to increase humeral retroversion on the dominant side compared with that on the nondominant side. To investigate the correlation between humeral retroversion and length of baseball career before age 16 years. Cross-sectional study; Level of evidence, 3. A total of 112 high school baseball players (32 pitchers and 80 position players) with a mean age of 15.6 years (range, 15-16 years) were enrolled in the study. All participants completed questionnaires regarding their player position and the age when they started baseball and were given physical examinations. Shoulder range of motion and humeral retroversion were assessed on the dominant and nondominant sides. Humeral retroversion (rotation angle of the proximal humerus relative to the distal humerus) was measured ultrasonographically. Humeral retroversion was significantly greater on the dominant side than on the nondominant side in both pitchers (P < .0001) and position players (P = .0005). The side-to-side difference in humeral retroversion in pitchers (13.9° ± 11.2°) was significantly greater than that in position players (9.0° ± 11.1°, P = .0361). In pitchers, there was a significant negative correlation between humeral retroversion and the age at which the players had started baseball (P = .033, β = -2.494). These results suggest that humeral retroversion increases with decreasing age at commencement of a baseball career before age 16 years in pitchers. © 2016 The Author(s).

Cleft lip and palate is a common congenital malformation with a prevalence of 1:600 newborns. Children with orofacial clefts are treated by an interdisciplinary team of specialists while parents and child play a key role in their own care process. The orthodontic and facial orthopedic treatment of a child with a cleft takes many years. Children often get bored of the long treatment and this can cause problems with compliance and oral hygiene. Therefore it is advisable to distinguish 5 well-defined stages in the orthodontic treatment and to attempt to have some 'orthodontics free' time in between. The 3 orthodontic treatment phases between the age of 9 and 20 years consist of orthodontic treatment concerning the closing of the cleft with a bone transplant, the treatment of the permanent dentition and, finally, a possible combined orthodontic surgical treatment at the end of the period of growth. Good interdisciplinary collaboration among the different dental disciplines is essential in this regard.

We aimed to prospectively examine the relationship between overall diet quality (reflecting adherence to dietary guidelines) and successful aging in a population-based cohort of older adults. In this population-based cohort study, we analyzed 10-year follow-up data from 1,609 adults aged 49 years and older, who were free of cancer, coronary artery disease, and stroke at the baseline and who had complete dietary data. Dietary data were collected using a semiquantitative food frequency questionnaire. Total diet scores (TDS) were allocated for intake of selected food groups and nutrients for each participant as described in the national dietary guidelines. Higher scores indicated closer adherence to dietary guidelines. Successful aging was defined as the absence of disability, depressive symptoms, cognitive impairment, respiratory symptoms, and chronic diseases (cancer, coronary artery disease, and stroke). At 10-year follow-up, 610 (37.9%) participants had died and 249 (15.5%) participants aged successfully. After multivariable adjustment, each 1-unit increase in TDS at baseline was associated with a 8% increased odds of successful aging 10 years later, odds ratio 1.08 (95% confidence interval 1.00-1.15). Participants in the highest (high adherence to dietary guidelines) versus lowest quartile (poor adherence to guidelines) of TDS at baseline had 58% higher odds of successful aging after 10 years, odds ratio 1.58 (95% confidence interval 1.02-2.46). Greater compliance with recommended national dietary guidelines (higher diet quality) was associated with an increased likelihood of successful aging, as determined through a multidomain approach. © The Author 2015.

We aimed to see whether primary percutaneous coronary intervention (PCI) benefits for ST-segment elevation myocardial infarction (STEMI) in the aged could be validated. Primary PCI benefits in elderly patients with STEMI remain uncertain. We reviewed 947 consecutive patients treated with primary PCI for STEMI: 331 were aged ≥75 years (older) and 616 <75 years (younger). The older group had higher percentage of renal insufficiency (7.9% vs. 3.1%, P = 0.0010), prior stroke (9.4% vs. 3.9%, P = 0.0006), 30-day mortality rate (7.6% vs. 3.9%, P = 0.015), and cardiac mortality rate (6.6% vs. 3.7%, P = 0.045). Successful reperfusion rates were similarly high in both groups (90.0% and 92.7%, P = 0.16), despite the higher proportion of patients with door-to-balloon time >90 min (15% vs. 8.4%, P = 0.0016) in older patients. Successful compared with unsuccessful PCI significantly decreased 30-day mortality rates in the older group (6.0% vs. 21%, P = 0.0018) and in the younger group (2.8% vs. 18%, P < 0.0001). When reperfusion was successful, cardiac mortality rate in older patients was not significantly greater than in younger patients (5.4% vs. 2.8%, P = 0.057). By multivariate analysis, unsuccessful reperfusion independently predicted 30-day mortality (odds ratio, 4.04; 95% confidence interval, 1.79-9.12; P = 0.0008), whereas age ≥75 years (odds ratio, 1.00; 95% confidence interval, 0.41-2.41; P = 0.99) and door-to-balloon time >90 min (odds ratio, 1.78; 95% confidence interval, 0.76-4.20; P = 0.19) did not. Pre-existing comorbidities characterize older patients developing STEMI. Aggressive PCI in older patients improves prognosis, and short door-to-balloon time is an important parameter conditioning the prognosis. Copyright © 2011 Wiley Periodicals, Inc.

Single-dose hepatitis A virus (HAV) vaccination was implemented in all Argentinean children 12 months of age in 2005. Previous studies demonstrated high prevalence of protective antibody response 4 years after single-dose vaccination. This study assessed long-term seroprotection against HAV after vaccination. Children who received 1 dose of HAV vaccine at 1 year of age at least 6 years before enrollment were included at 5 centers in Argentina between 2013 and 2014. Demographic and socioeconomic characteristics were collected through a questionnaire. Blood samples were tested for anti-HAV antibodies. Antibody values ≥10 mIU/mL were considered seroprotective. Logistic regression analysis was performed to evaluate the association between demographic and socioeconomic variables and seroprotection. A total of 1088 children were included, with a median postvaccination interval of 7.7 years (range 6.3-9.2 years). Of these children, 97.4% (95% confidence interval: 96.3%-98.3%) had protective antibodies against HAV. No association between demographic or socioeconomic variables and seroprotection was found. Geometric mean concentration of antibody levels against HAV was 170.5 mUI/mL (95% confidence interval: 163.2-178.2 mUI/mL). Single-dose universal hepatitis A immunization in 1-year-old children resulted in sustained immunologic protection for up to 9 years in Argentina. These findings, along with the low current disease burden, confirm the success of the intervention.

Conjugate vaccines are the best public health tools available for preventing most invasive diseases caused by Haemophilus influenzae type b (Hib), but the high cost of the vaccines has so far kept them from being introduced worldwide. The objective of this study was to estimate the cost-effectiveness of introducing Hib conjugate vaccines for the prevention of meningitis and pneumonia among children under 2 years of age in Colombia. We estimated the direct and indirect costs of managing in-hospital pneumonia and meningitis cases. In addition, following the recommendations of the World Health Organization, we assessed the cost-effectiveness of Hib vaccination programs. We also estimated the costs for preventing Hib cases, and the cost per year of life saved in two hypothetical situations: (1) with vaccination against Hib (with 90% coverage) and (2) without vaccination. The average in-hospital treatment costs were 611.50 US$ (95% confidence interval (95% CI) = 532.2 to 690.8 US$) per case of pneumonia and 848.9 US$ (95% CI = 716.8 to 981.0 US$) per case of meningitis. The average cost per Hib case prevented was 316.7 US$ (95% CI = 294.2 to 339.2 US$). In terms of cost-effectiveness, the cost would be 2.38 US$ per year of life saved for vaccination, versus 3.81 US$ per year of life saved without vaccination. Having an adequate Hib vaccination program in Colombia could prevent around 25,000 cases of invasive disease per year, representing a cost savings of at least 15 million US$ annually. Furthermore, the program could prevent some 700 deaths per year and save 44,054 years of life per year.

Purpose To assess the prevalence of astigmatism and its relationship with biometric optic components in preterm school children with diode laser-treated threshold retinopathy of prematurity (ROP). Methods A prospective, cross-sectional study in which cycloplegic keratometry, refraction, and ultrasound biometric measurement of optic components were performed on 24 consecutive preterm children with diode laser-treated threshold ROP at the age of 9 years. The study results were compared with data on 1021 age-matched full-term control children from a national survey. Results The laser-treated eyes had a mean astigmatism of 3.47 D, with a mean spherical equivalent of −4.49 D. Of the 46 eyes studied, 98% of eyes showed astigmatism ≥0.5 D and 50% had high astigmatism (>3.0 D). Most astigmatic eyes (97.7%) showed with-the-rule astigmatism, with the mean plus cylinder axis at 89.30o. Further correlation analysis showed the astigmatism in refraction was highly correlated with the corneal astigmatism (r=0.921, P<0.001) and the vertical corneal curvature (r=0.405, P=0.005). There was significantly steeper vertical corneal curvature (P=0.003) and flatter horizontal corneal curvature (P=0.031) in eyes with laser-treated ROP when compared with age-matched full-term controls. The eyes with laser-treated ROP also show significantly thicker lens (3.93 mm) and shallower anterior chamber depth (ACD; 2.92 mm) than full-term controls (P<0.001). Conclusions There is significantly higher prevalence and greater magnitude of astigmatism in eyes with laser-treated threshold ROP compared with full-term controls. The steeper vertical corneal curvature component contributes to the increased astigmatism in eyes with laser-treated ROP. PMID:23222565

Abdominal myomectomy remains the mainstay of surgical management of uterine fibroids in our environment. However, its benefit in women aged 40 years and above remains debatable. An 11-year prospective study was conducted involving 98 women, aged 40 years and above, who had abdominal myomectomy for the treatment of uterine fibroid at the University of Maiduguri Teaching Hospital, Maiduguri. They were followed up regularly for 1-6 years to detect conception, resolution of symptoms and obstetrics performance. Data were analyzed using SPSS version 13. The mean age of the patients was 42.6±2.9 years and 77 (78.6%) of them were nulliparous. Lower abdominal swelling was the commonest clinical presentation and the mean uterine size was 18.6±8.5 weeks. Infertility with uterine fibroids was the indication for myomectomy in majority of the cases [48 (48.9%)], while pregnancy complications accounted for 11.2% (11) of the cases Fertility restoration was 10.4% among the infertile patients. There was complete resolution of symptoms in 35.9% of those who required symptomatic relief, and term pregnancies were recorded in 72.7% of patients with pregnancy complications. Myomectomy is the recommended treatment of uterine fibroids in women aged 40 years and above with infertility and who wish to become pregnant. If there is no need for further fertility preservation, hysterectomy should be offered.

Diabetic cardiomyopathy is related to oxidative stress and correlated with the presence of advanced glycation end products (AGEs). In a clinical setting, AGEs can be detected in patients presenting diabetic cardiomyopathy; however, the underlying mechanism has yet to be elucidated. In our previous study, AGEs increase cell hypertrophy via ERK phosphorylation in a process closely related to ROS production. Thus, we propose that AGEs regulate the antioxidant gene nuclear factor-erythroid 2-related factor (Nrf-2). In H9c2 cells treated with AGEs, the expression of Nrf-2 was reduced; however, ERK phosphorylation was shown to increase. Treatment with H2O2 was also shown to increase Nrf-2 and ERK phosphorylation. In cells pretreatment with ROS scavenger NAC, the effects of H2O2 were reduced; however, the effects of the AGEs remained largely unchanged. Conversely, when cells were pretreated with PD98059 (ERK inhibitor), the expression of Nrf-2 was recovered following treatment with AGEs. Our results suggest that AGEs inhibit Nrf-2 via the ERK pathway; however, this influence is partly associated with ROS. Our finding further indicated that AGEs possess both ROS-dependent and ROS-independent pathways, resulting in a reduction in Nrf-2. This report reveals an important mechanism underlying the regulation of diabetic cardiomyopathy progression by AGEs.

AIM—To assess the role of etamsylate* in reducing the risk of haemorrhagic brain damage and its consequences.
DESIGN—Follow up of babies recruited into a randomised controlled trial.
METHODS—A total of 334 infants born before 33 weeks gestation in France and Greece were randomly allocated within the first four hours of birth either to receive etamsylate or to act as controls. The principal outcomes in the trial were death or impairment and/or disability at the age of 2years.
RESULTS—Fifty nine children were lost to follow up. A total of 115 (34%) either died or had some impairment or disability, and 88(26%) either died or had severe impairment or disability at 2years of age. These outcomes did not differ significantly between the two randomised groups: relative risks and 95% confidence intervals 1.14 (0.78 to 1.4) and 1.17 (0.82 to 1.68) respectively. The findings were similar for all the prespecified subgroup analyses stratified by key prognostic factors at trial entry: country of birth, gestational age < or ⩾ 29 weeks, inborn or outborn, age < or ⩾ 1 hour, and with or without cerebral scan abnormality.
CONCLUSION—These findings do not support the use of etamsylate. Other strategies need to be evaluated for the prevention of mortality and morbidity in these vulnerable infants.

To determine the cross-sectional characteristics of menstruating girls, dysmenorrhea, and the frequencies of related problems. Descriptive, cross-sectional study. Randomly selected primary, junior, and high schools in the city center of Kayseri. Two thousand female adolescents of ages between 9 and 18 years. We used a questionnaire addressing the epidemiological characteristics of menstruation, such as age at menarche, duration of menstrual intervals, average days of bleeding, and any menstrual problems and their frequencies. This study consists of a sufficient number of participants from all age groups. Of the participant (n = 2000) girls, 63.7% (n = 1274) had started menstruating. The mean age at menarche was 12.74 (±1.03) years. With a prevalence of 84.8% (n = 1080), dysmenorrhea was the most prevalent menstrual problem and the average pain score was 5.87 (±2.45). Of the menstruating girls, 34% (n = 439) used painkillers, the most commonly used was acetaminophen; during their period the prevalence of nonmedical methods to relieve pain was 35.2%; the rate of seeking medical help for dysmenorrhea was 9.3% (n = 119). In menstruating participants, 90.8% discussed their menstrual problems with their mothers. The rate of school absenteeism in menstruating girls was 15.9% in general and 18% in those with dysmenorrhea. Problems related to menstruation are common in adolescents and these problems affect their social life. In adolescent girls, the most common menstrual problem is dysmenorrhea and it affects school performance and attendance. Girls with menstrual problems showed a low rate of seeking medical help.

Low physical activity is a major health issue among Chinese Americans. This study explored Chinese-American children's physical activity behaviors and influencing factors. Twenty-five children of Chinese or Taiwanese descent were interviewed to understand their favorite sports or physical activities, physical activity environments, and influences on their physical activity. All were between the ages of 9 and 13. Interviews were transcribed and coded using thematic data analysis procedures. Major themes included: (1) team sports, particularly basketball, were commonly listed as favorite sports or activities; (2) physical activity occurred mostly at school or an after-school setting; and (3) family played a major role in physical activity. Some trends/differences were detected based on age, sex, and socioeconomic status. Interventions to promote physical activity among Chinese-American children should emphasize team sports and encourage physical activity in schools, but also explore ways to involves families outside of school.

Several indicators have been used to analyze scientific journals, with the impact factor and the number of citations in a 2-yr calendar time frame (2-YRC) being the most common factors. However, considering that the Journal of Applied Physiology (JAPPL) appears monthly and that calculations of these indicators are based on citations of papers published in previous years, we hypothesized that articles published at the beginning of the year would be cited more in the 2-YRC compared with those appearing in the last issues of the year, a phenomena known as a relative age effect. Our objective was to confirm the existence of a relative age effect in the 2-YRC for original articles published in JAPPL. From 2005 to 2008, a total of 1,726 original articles were published, according to the Web of Science, and 9,973 citations in 2-YRC, varying from 0 to 45, with a mean of 5.78 for individual papers. Although there were no differences in the number of original articles published in a given month (P = 0.99), the 2-YRC varied considerably throughout the year, being higher for those earlier issues of the year, as shown by the linear regression analysis (r(2) = 0.76; P < 0.001). The 2-YRC began at 6.62 during the first 3 mo of the year, dropping by 10% at each 3-mo period. In summary, the longer an article has been out there, the more citations it collects. The relative age effect is a potential confounding variable for the assessment and interpretation of 2-YRC (using calendar years) from JAPPL original articles.

Abstract Objectives: Inflammatory bowel disease [IBD] presenting in early childhood is extremely rare. More recently, progress has been made to identify children with monogenic forms of IBD predominantly presenting very early in life. In this study, we describe the heterogeneous phenotypes and genotypes of patients with IBD presenting before the age of 2 years and establish phenotypic features associated with underlying monogenicity. Methods: Phenotype data of 62 children with disease onset before the age of 2 years presenting over the past 20 years were reviewed. Children without previously established genetic diagnosis were prospectively recruited for next-generation sequencing. Results: In all, 62 patients [55% male] were identified. The median disease onset was 3 months of age (interquartile range [IQR]: 1 to 11). Conventional IBD classification only applied to 15 patients with Crohn’s disease [CD]-like [24%] and three with ulcerative colitis [UC]-like [5%] phenotype; 44 patients [71%] were diagnosed with otherwise unclassifiable IBD. Patients frequently required parenteral nutrition [40%], extensive immunosuppression [31%], haematopoietic stem-cell transplantation [29%], and abdominal surgery [19%]. In 31% of patients, underlying monogenic diseases were established [EPCAM, IL10, IL10RA, IL10RB, FOXP3, LRBA, SKIV2L, TTC37, TTC7A]. Phenotypic features significantly more prevalent in monogenic IBD were: consanguinity, disease onset before the 6th month of life, stunting, extensive intestinal disease and histological evidence of epithelial abnormalities. Conclusions: IBD in children with disease onset before the age of 2 years is frequently unclassifiable into Crohn’s disease and ulcerative colitis, particularly treatment resistant, and can be indistinguishable from monogenic diseases with IBD-like phenotype.

Background: Exposure to some perfluoroalkyl substances (PFAS), such as perfluorohexane sulfonate (PFHxS), perfluorooctanoate (PFOA), perfluorooctane sulfonate (PFOS), and perfluorononanoic acid (PFNA), may alter levels of sex hormones and insulin-like growth factor-1 (IGF-1) in animals. Human studies on this topic are scarce, and none have been conducted in young children. Objectives: We investigated the relationship between levels of PFAS and estradiol, total testosterone, and IGF-1 in 2,292 children (6–9 years of age) from the C8 Health Project who lived near a chemical plant in the Mid-Ohio Valley (USA) with local contamination from PFOA. Methods: Serum samples were collected in 2005–2006 and analyzed for PFAS, sex hormones, and IGF-1. Results from regression models were expressed as the adjusted percentage difference (95% CI) per sex-specific interquartile range (IQR) increment of each PFAS serum concentration. Analyses by PFAS quartiles were also conducted. Results: Median concentrations of PFHxS, PFOA, PFOS, and PFNA were 8, 35, 22, and 1.7 ng/mL in boys and 7, 30, 21, and 1.7 ng/mL in girls. In boys, PFOA concentrations were significantly associated with testosterone levels (–4.9%; 95% CI: –8.7, –0.8%); PFOS with estradiol (–4.0%; 95% CI: –7.7, –0.1%), testosterone (–5.8%; 95% CI: –9.4, –2.0%), and IGF-1 (–5.9%; 95% CI: –8.3, –3.3%); and PFNA with IGF-1 (–3.5%; 95% CI: –6.0, –1.0%). In girls, significant associations were found between PFOS and testosterone (–6.6%; 95% CI: –10.1, –2.8%) and IGF-1 (–5.6%; –8.2, –2.9%); and PFNA and IGF-1 (–3.8%; 95% CI: –6.4, –1.2%). In both sexes, the magnitudes of the associations decreased monotonically across quartiles for both testosterone and IGF-1 in relation to PFOS, and for IGF-1 and PFNA in girls. Conclusions: To our knowledge, this is the first study suggesting that PFAS are associated with lower levels of IGF-1 and sex hormones in young children. Citation: Lopez

To compare the effects of Montessori education and traditional education on the intellectual development in children aged 2 to 4 years. Children aged between 2 to 3 years who were enrolled in a kindergarten in September 2006 were randomly assigned to the Montessori education and the traditional education groups. In addition to receiving the traditional education, the Montessori education group participated in the two-hour Montessori pedagogical activities every day. The intellectual development was evaluated by the Neuropsychological Development Examination Format for Children Aged 0~6 years published by Capital Pediatrics Research Institute at enrollment and one year after the trial. There were no significant differences in the intelligence growth level between the Montessori education and the traditional education groups at enrollment. After one year, the levels of fine movements, adaptation ability, language, and social behavior developments in the Montessori education group were significantly higher than those in the traditional education group (p<0.05 or 0.01). The intelligence increasing scores of the large motor ability, fine movements, language, social behavior and development quotient in the Montessori education group were also higher than those in the traditional education group (p<0.05 or 0.01). Montessori education can promote the development of large motor ability, fine movements, language, and social behavior in children.

This paper reports the toxicity of OPEC/OJEC chemotherapy in stage 4 neuroblastoma patients over 1 year of age. Ninety-five patients with stage 4 neuroblastoma received alternating courses of OPEC/OJEC--vincristine 1.5 mg/m2 (O), cisplatin 80 mg/m2 (P), etoposide 200 mg/m2 (E), cyclophosphamide 600 mg/m2 (C), and carboplatin 500 mg/m2 (J), every 21 days if there was haematological recovery. Seventy out of ninety-five (74%) patients completed seven or more courses and were evaluable for toxicity. Of these 70 patients, 33% had more than three episodes of fever and sepsis, 35% required more than five blood or platelet transfusions, 36% had grade 2 or more gastrointestinal toxicity and 9% had neurotoxicity. There was a median reduction in GFR of 32 ml/min/1.73 m2 (-46 to 134) and there was one toxic death. OPEC/OJEC is a well-tolerated therapy for stage 4 neuroblastoma over 1 year of age.

Parenting influences child development, but it is unclear whether early parenting behavior can influence school-age outcomes in very preterm (VPT) children, and/or if certain groups of VPT children may be more affected by early parenting behavior. These research questions were examined. Participants were 147 children born <30 weeks' gestation or birth weight <1250 g and their primary caregiver. At term corrected age (CA), magnetic resonance imaging (MRI) was used to determine presence and severity of brain abnormality and medical data collected. High medical risk was defined as the presence of at least one of sepsis, necrotizing enterocolitis, bronchopulmonary dysplasia, moderate to severe white matter abnormality on MRI, or postnatal corticosteroids. At 2 years CA, parent-child interaction was assessed, and at 7 years CA, general intelligence (IQ), language, executive function, academic skills, and social-emotional functioning were assessed. Higher levels of parent-child synchrony, and parent facilitation, sensitivity and positive affect at 2 years were associated with better child outcomes at 7 years, while higher levels of intrusiveness and negative affect were associated with poorer outcomes. Many of these relationships remained after controlling for early child cognitive development. Interactions between child medical risk (higher/lower) and parenting were limited to child reading, math, and executive functioning outcomes, with stronger relationships for lower medical risk children. The contribution of early parenting to VPT children's school-age performance is significant, with stronger effects for lower medical risk children in some outcomes. These findings support the premise that parenting strategies should be included in the NICU and early interventions programs for VPT infants. © 2015 Association for Child and Adolescent Mental Health.

We assessed whether baseline measurements of physical activity, aerobic fitness, body fat and abdominal fat were predictors of changes in body fat measurements over a two-year period. The study comprised of 204 children aged 9.8 ± 0.6 years with a normal body mass distribution, who recruited from four schools in middle-class areas of Malmö, Sweden, from 2001 to 2004. Peak oxygen uptake and physical activity were measured at baseline. Body fat was measured by dual-energy X-ray absorptiometry at baseline and two years later. Physical activity, aerobic fitness and total body fat or abdominal fat were predictors of change in total body fat or abdominal fat over a period of two years. Changes in the percentage of body fat were not related to any of the baseline measurements. Our two-year follow-up of children with a mean age of 9.8 years at baseline showed that physical activity, aerobic fitness and body fat or abdominal fat predicted changes in total body fat or abdominal fat, but not the percentage of body fat. ©2018 Foundation Acta Paediatrica.

Hippocampal sclerosis of aging (HS-Aging) is a common neurodegenerative condition associated with dementia. To learn more about genetic risk of HS-Aging pathology, we tested gene-based associations of the GRN, TMEM106B, ABCC9, and KCNMB2 genes, which were reported to be associated with HS-Aging pathology in previous studies. Genetic data were obtained from the Alzheimer’s Disease Genetics Consortium (ADGC), linked to autopsy-derived neuropathological outcomes from the National Alzheimer’s Coordinating Center (NACC). Of the 3,251 subjects included in the study, 271 (8.3%) were identified as an HS-Aging case. The significant gene-based association between the ABCC9 gene and HS-Aging appeared to be driven by a region in which a significant haplotype-based association was found. We tested this haplotype as an expression Quantitative Trait Locus (eQTL) using two different public-access brain gene expression databases. The HS-Aging pathology protective ABCC9 haplotype was associated with decreased ABCC9 expression, indicating a possible toxic gain of function. PMID:28131462

We examined the bidirectional relations between peer relations and attention problems from middle childhood through adolescence. Using data from the Longitudinal Study of Chinese Children and Adolescents (LSCCA, N = 2157, 51.9% male), three key aspects of peer relations (acceptance, rejection, and victimization) were assessed annually from 9 to 16 years of age. Attention problems were assessed at 9 and 15 years. Latent growth modeling indicated that greater attention problems at age 9 were linked with a lower intercept for peer acceptance, and higher intercepts for rejection and victimization. Also, prior lower acceptance and greater rejection and victimization, along with a higher increase over time in rejection and lower decrease over time in victimization, predicted attention problems at age 15. Cross-lagged analysis showed that attention problems were associated with less subsequent peer acceptance and greater subsequent rejection and victimization. Only peer rejection (but neither victimization nor acceptance) predicted more subsequent attention problems. Findings point to bidirectional associations between attention problems and peer relations in the developmental transition across adolescence. Evidence for differential bidirectionality of attention problems with the multiple peer experience (group versus dyadic; good versus bad) emerged, and future replications are needed.

Puberty is characterized by major changes in hormone levels and structural changes in the brain. To what extent these changes are associated and to what extent genes or environmental influences drive such an association is not clear. We acquired circulating levels of luteinizing hormone, follicle stimulating hormone (FSH), estradiol and testosterone and magnetic resonance images of the brain from 190 twins at age 9 [9.2 (0.11) years; 99 females/91 males]. This protocol was repeated at age 12 [12.1 (0.26) years] in 125 of these children (59 females/66 males). Using voxel-based morphometry, we tested whether circulating hormone levels are associated with grey matter density in boys and girls in a longitudinal, genetically informative design. In girls, changes in FSH level between the age of 9 and 12 positively associated with changes in grey matter density in areas covering the left hippocampus, left (pre)frontal areas, right cerebellum, and left anterior cingulate and precuneus. This association was mainly driven by environmental factors unique to the individual (i.e. the non-shared environment). In 12-year-old girls, a higher level of circulating estradiol levels was associated with lower grey matter density in frontal and parietal areas. This association was driven by environmental factors shared among the members of a twin pair. These findings show a pattern of physical and brain development going hand in hand.

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

Background The purpose of this study was to assess the relationship of smoking duration with respiratory symptoms and history of chronic obstructive pulmonary disease (COPD) in the South Carolina Behavioral Risk Factor Surveillance System survey in 2012. Methods Data from 4,135 adults aged ≥45 years with a smoking history were analyzed using multivariable logistic regression that accounted for sex, age, race/ethnicity, education, and current smoking status, as well as the complex sampling design. Results The distribution of smoking duration ranged from 19.2% (1–9 years) to 36.2% (≥30 years). Among 1,454 respondents who had smoked for ≥30 years, 58.3% were current smokers, 25.0% had frequent productive cough, 11.2% had frequent shortness of breath, 16.7% strongly agreed that shortness of breath affected physical activity, and 25.6% had been diagnosed with COPD. Prevalence of COPD and each respiratory symptom was lower among former smokers who quit ≥10 years earlier compared with current smokers. Smoking duration had a linear relationship with COPD (P<0.001) and all three respiratory symptoms (P<0.001) after adjusting for smoking status and other covariates. While COPD prevalence increased with prolonged smoking duration in both men and women, women had a higher age-adjusted prevalence of COPD in the 1–9 years, 20–29 years, and ≥30 years duration periods. Conclusion These state population data confirm that prolonged tobacco use is associated with respiratory symptoms and COPD after controlling for current smoking behavior. PMID:26229460

The aim of the study was to determine the association between the prevalence of clinically significant depression and age in a large representative sample of elderly German people. In the second follow-up (2005-2007) of the ESTHER cohort study, the 15-item geriatric depression scale (GDS-15) as well as a sociodemographic and clinical questionnaire were administered to a representative sample of 8270 people of ages 53 to 80 years. The prevalence of clinically significant depression was estimated using a GDS cut-off score of 5/6. Prevalence rates were estimated for the different age categories. Association between depression and age was analyzed using logistic regression, adjusted for gender, co-morbid medical disorders, education, marital status, physical activity, smoking, self-perceived cognitive impairment, and anti-depressive medication. Of the participants, 7878 (95.3%) completed more than twelve GDS items and were included in the study. The prevalence of clinically significant depression was 16.0% (95%CI = [15.2; 16.6]). The function of depression prevalence dependent on age group showed a U-shaped pattern (53-59: 21.0%, CI = [18.9; 23.3]; 60-64: 17.7%, CI = [15.7; 19.7]; 65-69: 12.6%, CI = [11.2; 14.0]; 70-74: 14.4%, CI = [12.6; 16.0]; 75-80: 17.1%, CI = [14.9; 19.4]). Adjusted odds ratios showed that the chances of being depressive decrease with the age category but remain relatively stable for people aged 65 and over. The prevalence of depression in the elderly seems to be associated with the age category. Adjusted odds ratios showed that people aged 60 and older had lower chances of being depressive than people aged 53 to 59 years. Copyright © 2011 John Wiley & Sons, Ltd.

Very young children undergoing hematopoietic cell transplantation (HCT) are a unique and vulnerable population. We analyzed outcomes of 717 patients from 117 centers who survived relapse free for ≥1 year after allogeneic myeloablative HCT for hematologic malignancy at <3 years of age, between 1987 and 2012. The median follow-up was 8.3 years (range, 1.0 to 26.4 years); median age at follow-up was 9 years (range, 2 to 29 years). Ten-year overall and relapse-free survival were 87% (95% confidence interval [CI], 85% to 90%) and 84% (95% CI, 81% to 87%). Ten-year cumulative incidence of relapse was 11% (95% CI, 9% to 13%). Of 84 deaths, relapse was the leading cause (43%). Chronic graft-versus-host-disease 1 year after HCT was associated with increased risk of mortality (hazard ratio [HR], 2.1; 95% CI, 1.3 to 3.3; P = .0018). Thirty percent of patients experienced ≥1 organ toxicity/late effect >1 year after HCT. The most frequent late effects included growth hormone deficiency/growth disturbance (10-year cumulative incidence, 23%; 95% CI, 19% to 28%), cataracts (18%; 95% CI, 15% to 22%), hypothyroidism (13%; 95% CI, 10% to 16%), gonadal dysfunction/infertility requiring hormone replacement (3%; 95% CI, 2% to 5%), and stroke/seizure (3%; 95% CI, 2% to 5%). Subsequent malignancy was reported in 3.6%. In multivariable analysis, total body irradiation (TBI) was predictive of increased risk of cataracts (HR, 17.2; 95% CI, 7.4 to 39.8; P < .001), growth deficiency (HR, 3.5; 95% CI, 2.2 to 5.5; P < .001), and hypothyroidism (HR, 5.3; 95% CI, 3.0 to 9.4; P < .001). In summary, those who survived relapse free ≥1 year after HCT for hematologic malignancy at <3 years of age had favorable overall survival. Chronic graft-versus-host-disease and TBI were associated with adverse outcomes. Future efforts should focus on reducing the risk of relapse and late effects after HCT at early age.

Identification of markers of abnormal brain function in children at-risk of schizophrenia may inform early intervention and prevention programs. Individuals with schizophrenia are characterised by attenuation of MMN amplitude, which indexes automatic auditory sensory processing. The current aim was to examine whether children who may be at increased risk of schizophrenia due to their presenting multiple putative antecedents of schizophrenia (ASz) are similarly characterised by MMN amplitude reductions, relative to typically developing (TD) children. EEG was recorded from 22 ASz and 24 TD children aged 9 to 12 years (matched on age, sex, and IQ) during a passive auditory oddball task (15% duration deviant). ASz children were those presenting: (1) speech and/or motor development lags/problems; (2) social, emotional, or behavioural problems in the clinical range; and (3) psychotic-like experiences. TD children presented no antecedents, and had no family history of a schizophrenia spectrum disorder. MMN amplitude, but not latency, was significantly greater at frontal sites in the ASz group than in the TD group. Although the MMN exhibited by the children at risk of schizophrenia was unlike that of their typically developing peers, it also differed from the reduced MMN amplitude observed in adults with schizophrenia. This may reflect developmental and disease effects in a pre-prodromal phase of psychosis onset. Longitudinal follow-up is necessary to establish the developmental trajectory of MMN in at-risk children. Copyright © 2013 The Authors. Published by Elsevier B.V. All rights reserved.

Background: Children’s health is a current concern and data suggests that poor fundamental movement skills (FMS) could be associated with poor health, which may or may not be mediated by low physical activity level. However, tools to assess FMS have not been standardized, and could consequently lead to different associations between FMS and health indicators. Objective: The primary objective of this study was to evaluate the associations between FMS and health indicators using two different FMS measurement tools often used in Canada. Methods: A total of 145 children between the ages of 9 to 12 were recruited from schools, after school programs, and summer camps in 2016. FMS were evaluated using the Passport for Life (bound, plank, run, kick, throw) and the PLAYbasic (run, hop, throw, kick, and balance). The association between each test and an average score for each tool were tests with health indicators including anthropometric measures, grip strength, cardiorespiratory fitness, and percent body fat. Results: Participants were composed of 54.2% boys aged 10.4 ± 1.2 years with an average body mass index of 18.8 ± 3.8 kg/m2. The association between the average score of both tools was 0.77 (p < 0.01), body mass index was significantly associated with 67% of FMS elements using the Passport for Life (r ranging from −0.18 to −0.32; p < 0.05), and 60% of FMS using the PLAYbasic (r ranging from −0.15 to −0.30; p < 0.05). There were no significant differences between the associations of the health indicators with FMS and either FMS assessment tool (Passport for Life and PLAYbasic) (p = 0.05). Average score of FMS was significantly associated with all health indicators using both PLAYbasic and Passport for Life (all p < 0.05). Conclusions: Health indicators in children are associated with FMS regardless of whether the Passport for Life or the PLAYbasic was used as the assessment tool. It is worth investigating if interventions that improve FMS lead to

Background Obesity increases risk of premature disease, and may be associated with unfavorable lifestyle changes that add to risk. This study analyzed the association of midlife BMI change with current lifestyle patterns among multiethnic men. Methods Men aged 40-60 years (n=9864) retrospectively reported body weight between ages 20-40 years and current dietary, TV, physical activity and sleep practices in the Adventist Health Study II, a study of church-goers in the US and Canada. In multivariate logistic regression analysis, odds ratios for BMI gain were calculated for each lifestyle practice controlling for sociodemographic and other lifestyle factors and current BMI. Results Men with median or higher BMI gain (2.79 kg/m2) between ages 20-40 years were more likely to consume a non-vegetarian diet, and engage in excessive TV watching and little physical activity and had a shorter sleep duration compared to men with BMI gain below the median (all p<0.001). In multivariate logistic analysis current BMI was significantly associated with all lifestyle factors in multivariate analyses (all p≤0.005). BMI gain was associated with lower odds of vegetarian diet (odds ratio [OR] 0.939; 95% confidence interval [CI] 0.921-0.957) and of physical activity ≥150 minutes/week (OR 0.979, 95% CI 0.960-0.999). Conclusions These findings imply that diet and less physical activity are associated with both gained and attained BMI, while inactivity (TV watching) and short sleep duration correlated only with attained BMI. Unhealthy lifestyle may add risk to that associated with BMI. Longitudinal and intervention studies are needed to infer causal relationships. PMID:25434910

Childhood maltreatment is linked with increased risk for mental illness in adolescence and adulthood. However, little evidence is available on whether different forms of maltreatment have specific effects, and no prospective studies in low- or middle-income countries have addressed this issue. Participants in a population-based, birth cohort study in Pelotas, Brazil (N=3715) self-reported exposure to maltreatment (emotional abuse, physical neglect, physical abuse, sexual abuse, domestic violence) in confidential questionnaires at age 15 years, and were assessed for major depression in interviews at age 18 years, using the MINI. Confounding variables concerning family characteristics were measured in interviews with mothers in the perinatal period and at age 11 years. Females exposed to emotional abuse (OR=2.7; 95%CI=1.9, 3.8) and domestic violence (OR=1.9; 95%CI=1.2, 2.9) were at increased risk for depression after adjustment for confounders and other types of maltreatment. Females exposed to two or more forms of maltreatment were at particularly high risk for depression (OR=4.1; 95%Cl=2.8, 6.1) compared with females not exposed to maltreatment. In adjusted analyses, maltreatment was not associated with depression for males. Detailed information about maltreatment such as timing and frequency was not available, and 1534 individuals were not included in the analyses, who had poorer and less educated mothers. Emotional abuse and domestic violence are strong risk factors for major depression for females. Early intervention to prevent maltreatment and its consequences is critical, especially for girls exposed to poly-maltreatment. Copyright © 2017 The Authors. Published by Elsevier B.V.

Inflammatory bowel disease [IBD] presenting in early childhood is extremely rare. More recently, progress has been made to identify children with monogenic forms of IBD predominantly presenting very early in life. In this study, we describe the heterogeneous phenotypes and genotypes of patients with IBD presenting before the age of 2 years and establish phenotypic features associated with underlying monogenicity. Phenotype data of 62 children with disease onset before the age of 2 years presenting over the past 20 years were reviewed. Children without previously established genetic diagnosis were prospectively recruited for next-generation sequencing. In all, 62 patients [55% male] were identified. The median disease onset was 3 months of age (interquartile range [IQR]: 1 to 11). Conventional IBD classification only applied to 15 patients with Crohn's disease [CD]-like [24%] and three with ulcerative colitis [UC]-like [5%] phenotype; 44 patients [71%] were diagnosed with otherwise unclassifiable IBD. Patients frequently required parenteral nutrition [40%], extensive immunosuppression [31%], haematopoietic stem-cell transplantation [29%], and abdominal surgery [19%]. In 31% of patients, underlying monogenic diseases were established [EPCAM, IL10, IL10RA, IL10RB, FOXP3, LRBA, SKIV2L, TTC37, TTC7A]. Phenotypic features significantly more prevalent in monogenic IBD were: consanguinity, disease onset before the 6th month of life, stunting, extensive intestinal disease and histological evidence of epithelial abnormalities. IBD in children with disease onset before the age of 2 years is frequently unclassifiable into Crohn's disease and ulcerative colitis, particularly treatment resistant, and can be indistinguishable from monogenic diseases with IBD-like phenotype.

We studied prospectively the midlife handgrip strength, living habits, and parents' longevity as predictors of length of life up to becoming a centenarian. The participants were 2,239 men from the Honolulu Heart Program/Honolulu-Asia Aging Study who were born before the end of June 1909 and who took part in baseline physical assessment in 1965-1968, when they were 56-68 years old. Deaths were followed until the end of June 2009 for 44 years with complete ascertainment. Longevity was categorized as centenarian (≥100 years, n = 47), nonagenarian (90-99 years, n = 545), octogenarian (80-89 years, n = 847), and ≤79 years (n = 801, reference). The average survival after baseline was 20.8 years (SD = 9.62). Compared with people who died at the age of ≤79 years, centenarians belonged 2.5 times (odds ratio (OR) = 2.52, 95% confidence interval (CI) = 1.23-5.10) more often to the highest third of grip strength in midlife, were never smokers (OR = 5.75 95% CI = 3.06-10.80), had participated in physical activity outside work (OR = 1.13 per daily hour, 95% CI = 1.02-1.25), and had a long-lived mother (≥80 vs. ≤60 years, OR = 2.3, 95% CI = 1.06-5.01). Associations for nonagenarians and octogenarians were parallel, but weaker. Multivariate modeling showed that mother's longevity and offspring's grip strength operated through the same or overlapping pathway to longevity. High midlife grip strength and long-lived mother may indicate resilience to aging, which, combined with healthy lifestyle, increases the probability of extreme longevity.

If you consider that at some point in life 50% of sexually active women have had an infection with the human papilloma virus is indisputable that any attempt to reduce the prevalence worth undertaking it. The vaccine to prevent HIV infection has not enjoyed the same degree of acceptance than others, hence the interest in knowing some of the reasons that has not achieved universal vaccination. To examine human papillomavirus (HPV) vaccine acceptability among mothers with adolescents girls between 9 and 13 years old. The mothers were interrogated about HVP vaccine acceptability, reasons provided for acceptance or non-acceptance and if mothers know that vaccine is offered free for public health institutions We interview a 250 mothers with 281 daughters, 38 daughters have already received the vaccine. Eighty nine percent of the mothers reacted positively to the possibility of vaccinating theirs daughters. The reasons of vaccine non-acceptance were because not knowing enough about infection, mother felt that their daughters were not at risk for acquiring HVP infection, the vaccine is new and mothers unknown side effects. Thirty nine percent of the mothers want to know more about the vaccine safety, 21% about length protection duration and 16% concerning about if the vaccine is effective. Fifty seven per cent of the mothers know that Health Secretary offers vaccine free. Mothers whom have been vaccinated their daughters, had daughters with lower age (9.8 +/- 0.9 vs 10.8 +/- 1.3 years, p = 0.0001), were more frequently married (79 vs 51%, p = 0.002) and more likely to report that they had heard about VPH vaccine from some source (100 vs 66%, p = 0.0001) that mothers have not yet vaccinated their daughters. The acceptability of VPH vaccine was 89%. Continued health education and propaganda is needed to promote a better knowledge of VPH vaccine.

We evaluated antibody persistence up to 68 months (M) post-vaccination with a quadrivalent meningococcal serogroups A, C, W and Y tetanus toxoid conjugate vaccine (MenACWY-TT) or a licensed monovalent MenC conjugate vaccine (MenC-CRM 197 ) and subsequent booster responses to MenACWY-TT in healthy European children. In the initial study (NCT00674583), healthy children, 2-10 years of age, were randomized to receive a single dose of either MenACWY-TT or MenC-CRM 197 . In the follow-up study, we present the persistence at 32, 44, 56, and 68 M post-vaccination, overall and stratified by age (2-5 and 6-10 years), and the immunogenicity and safety of MenACWY-TT administered to all study participants at M68 post-primary vaccination. At M68, 33.3% (age group 2-5 years) and 47.1% (age group 6-10 years) of the children vaccinated with MenACWY-TT, and 50.0% (age group 2-5 years) and 75.9% (age group 6-10 years) vaccinated with MenC-CRM 197 retained titers ≥1:8 for MenC, as assessed by a serum bactericidal assay using rabbit complement (rSBA). In the MenACWY-TT recipients, the percentages of children retaining rSBA titers ≥1:8 for MenA, MenW, and MenY were 81.7%, 47.3% and 66.7% in age group 2-5 years and 91.8%, 58,8% and 76.5% in age group 6-10 years, respectively. The booster dose induced robust responses (100% for all serogroups) and was well-tolerated. Antibody persistence (rSBA titers ≥ 1:8) for serogroups A, W and Y was observed in more than 50.0% of the children 68 M after receiving one dose of MenACWY-TT; for MenC, antibody persistence was observed in more than one third of MenACWY-TT and more than half of MenC-CRM 197 recipients. Vaccination with a booster dose of MenACWY-TT induced robust immune responses for all serogroups. Copyright © 2018. Published by Elsevier Ltd.

To assess the prevalence of early confluent/confluent white matter lesions (ec/cWMLs) in asymptomatic individuals aged ≥50 years and to identify associated clinical phenotypes. Cross-sectional analysis of 141 asymptomatic individuals aged ≥50 years assessed at an outpatient department in France. Brain magnetic resonance imaging was rated using the Fazekas scale. Age-adjusted odds ratios (ORs) and 95% confidence intervals were estimated using logistic models to investigate factors associated with ec/cWMLs; independent risk factors were identified by multivariate analysis. Median age was 63 years; 53.9% were women, 32.6% had hypertension, and 76.6% had ≥1 cardiovascular risk factors. The prevalence of ec/cWMLs was 26.2%. Apart from age, independent risk factors were family history of cardiovascular event (OR = 5.55; 1.13-27.32) and hypertension (2.47; 1.05-5.81). Patients with ec/cWMLs had lower cognitive dual-task walking speed (1.15; 0.98-1.40), MMSE (1.41; 1.06-1.89), and FAB scores (5.21; 1.49-19.84). The Scheltens score was independently associated with the WML severity score. ec/cWMLs are common in asymptomatic community-dwelling individuals aged ≥50 years. They are associated with cardiovascular risk factors, impairments in global and executive cognitive function, and Scheltens score elevation. © 2016 S. Karger AG, Basel.

To determine the prevalence of overweight, obesity and chronic malnutrition in 6- to 9-year-old children in Peru. A cross-cutting study based on the 2009-2010 National Household Survey. The size/age ratio was analyzed with references of the National Center for Health Statistic (NCSH) and the World Health Organization (WHO), considering less than two standard deviations for chronic malnutrition (CM); and the Must and WHO reference tables to measure the body mass index with 85 to 95 percentile values for overweight and above 95 for obesity. With Must as reference, overweight was 12.1% and obesity 9.4%, and according to WHO overweight and obesity were 10.2 and 11.3% respectively. The prevalence of CM according to NCSH and WHO is 15.4 and 17.8% respectively. The highest prevalence of CM is in the north (25.2%), center (22.9%) and south of (19%) the Highland, while obesity is more present in the south coast (28%), Metropolitan Lima (22.8%) and the central Coast (22.5%). Of all the children with CM, 6.5% has overweight and 1.2% obesity. CM is decreasing because size averages have improved, however obesity has doubled. The presence of CM and obesity in children aged 6 to 9 years old in different regions of Peru poses a challenge in the planning of food and nutrition policies.

High television exposure time at young age has been described as a potential risk factor for developing behavioral problems. However, less is known about the effects of preschool television on subsequent bullying involvement. We examined the association between television viewing time through ages 2-5 and bullying involvement in the first grades of elementary school. We hypothesized that high television exposure increases the risk of bullying involvement. TV viewing time was assessed repeatedly in early childhood using parental report. To combine these repeated assessments we used latent class analysis. Four exposure classes were identified and labeled "low", "mid-low", "mid-high" and "high". Bullying involvement was assessed by teacher questionnaire (n=3423, mean age 6.8 years). Additionally, peer/self-report of bullying involvement was obtained using a peer nomination procedure (n=1176, mean age 7.6 years). We examined child risk of being a bully, victim or a bully-victim (compared to being uninvolved in bullying). High television exposure class was associated with elevated risks of bullying and victimization. Also, in both teacher- and child-reported data, children in the high television exposure class were more likely to be a bully-victim (OR=2.11, 95% CI: 1.42-3.13 and OR=3.68, 95% CI: 1.75-7.74 respectively). However, all univariate effect estimates attenuated and were no longer statistically significant once adjusted for maternal and child covariates. The association between television viewing time through ages 2-5 and bullying involvement in early elementary school is confounded by maternal and child socio-demographic characteristics.

In 2015, an estimated 18.4 million U.S. adults had current asthma, and 3,396 adult asthma deaths were reported (1). An estimated 11%-21% of asthma deaths might be attributable to occupational exposures (2). To describe asthma mortality among persons aged 15-64 years,* CDC analyzed multiple cause-of-death data † for 1999-2016 and industry and occupation information collected from 26 states § for the years 1999, 2003, 2004, and 2007-2012. Proportionate mortality ratios (PMRs) ¶ for asthma among persons aged 15-64 years were calculated. During 1999-2016, a total of 14,296 (42.9%) asthma deaths occurred among males and 19,011 (57.1%) occurred among females. Based on an estimate that 11%-21% of asthma deaths might be related to occupational exposures, during this 18-year period, 1,573-3,002 asthma deaths in males and 2,091-3,992 deaths in females might have resulted from occupational exposures. Some of these deaths might have been averted by instituting measures to prevent potential workplace exposures. The annual age-adjusted asthma death rate** per 1 million persons aged 15-64 years declined from 13.59 in 1999 to 9.34 in 2016 (p<0.001) among females, and from 9.14 (1999) to 7.78 (2016) (p<0.05) among males. The highest significantly elevated asthma PMRs for males were for those in the food, beverage, and tobacco products manufacturing industry (1.82) and for females were for those in the social assistance industry (1.35) and those in community and social services occupations (1.46). Elevated asthma mortality among workers in certain industries and occupations underscores the importance of optimal asthma management and identification and prevention of potential workplace exposures.

The present work was carried out to study the prevalence of Tinea capitis (TC) in Campania over a 9-year period and also to delineate the prevalence of the causative fungus responsible and the clinical forms of tinea capitis. This retrospective study included all the cases of TC occurring between January 2004 and December 2012 to the Mycology Laboratory at the University of Naples "Federico II" and mycologically confirmed. Samples for potassium hydroxide 20% mounts and fungal cultures were collected. Sabouraud dextrose agar were inoculated with the samples. TC was diagnosed by direct microscopy and culture in 143 patients. TC was found to be most common in the group including patients aged between 1-18 years; 13% of patients were over 18 years old. Non-inflammatory clinical forms were the most common type (80.4%). M. canis was the dermatophyte most frequently isolated (64.1%). Microscopic examination revealed an ectothrix pattern of hair invasion to be more common (72% cases). TC was clinical and mycologically diagnosed in 143 patients. It was prevalent in patients aged 1-18 years old; 73.2% of adults affected by TC had possible risk factors and in these patients TC often presented in atypical forms; atypical forms were also observed in children. M. canis was the most common dermatophyte species isolated in children, T. rubrum in adults. We noticed a significant increase of anthropophilic dermatophytes possibly linked to the immigration from African countries. For the diagnosis of TC, mycological examinations are essential.

Background Rheumatic heart disease (RHD) is considered a major public health problem in developing countries, although scarce data are available to substantiate this. Here we quantify mortality from RHD in Fiji during 2008–2012 in people aged 5–69 years. Methods and Findings Using 1,773,999 records derived from multiple sources of routine clinical and administrative data, we used probabilistic record-linkage to define a cohort of 2,619 persons diagnosed with RHD, observed for all-cause mortality over 11,538 person-years. Using relative survival methods, we estimated there were 378 RHD-attributable deaths, almost half of which occurred before age 40 years. Using census data as the denominator, we calculated there were 9.9 deaths (95% CI 9.8–10.0) and 331 years of life-lost (YLL, 95% CI 330.4–331.5) due to RHD per 100,000 person-years, standardised to the portion of the WHO World Standard Population aged 0–69 years. Valuing life using Fiji’s per-capita gross domestic product, we estimated these deaths cost United States Dollar $6,077,431 annually. Compared to vital registration data for 2011–2012, we calculated there were 1.6-times more RHD-attributable deaths than the number reported, and found our estimate of RHD mortality exceeded all but the five leading reported causes of premature death, based on collapsed underlying cause-of-death diagnoses. Conclusions Rheumatic heart disease is a leading cause of premature death as well as an important economic burden in this setting. Age-standardised death rates are more than twice those reported in current global estimates. Linkage of routine data provides an efficient tool to better define the epidemiology of neglected diseases. PMID:26371755

Animal models indicate that exposure to choline in utero improves visual memory through cholinergic transmission and/or epigenetic mechanisms. Among 895 mothers in Project Viva (eastern Massachusetts, 1999-2002 to 2008-2011), we estimated the associations between intakes of choline, vitamin B12, betaine, and folate during the first and second trimesters of pregnancy and offspring visual memory (measured by the Wide Range Assessment of Memory and Learning, Second Edition (WRAML2), Design and Picture Memory subtests) and intelligence (measured using the Kaufman Brief Intelligence Test, Second Edition (KBIT-2)) at age 7 years. Mean second-trimester intakes were 328 (standard deviation (SD), 63) mg/day for choline, 10.5 (SD, 5.1) µg/day for vitamin B12, 240 (SD, 104) mg/day for betaine, and 1,268 (SD, 381) µg/day for folate. Mean age 7 test scores were 17.2 (SD, 4.4) points on the WRAML 2 Design and Picture Memory subtests, 114.3 (SD, 13.9) points on the verbal KBIT-2, and 107.8 (SD, 16.5) points on the nonverbal KBIT-2. In a model adjusting for maternal characteristics, the other nutrients, and child's age and sex, the top quartile of second-trimester choline intake was associated with a child WRAML2 score 1.4 points higher (95% confidence interval: 0.5, 2.4) than the bottom quartile (P-trend = 0.003). Results for first-trimester intake were in the same direction but weaker. Intake of the other nutrients was not associated with the cognitive tests administered. Higher gestational choline intake was associated with modestly better child visual memory at age 7 years.

Study Objectives: To examine associations between specific parasomnias and psychotic experiences in childhood. Design: Birth cohort study. Information on the presence of frequent nightmares in children was obtained prospectively from mothers during multiple assessments conducted when children were aged between 2.5 and 9 y. Children were interviewed at age 12 y about nightmares, night terrors, sleepwalking, and psychotic experiences (delusions, hallucinations, and thought interference) occurring in the previous 6 mo. Setting: Assessments were completed in participants' homes or a University clinic within the UK. Patients or Participants: There were 6,796 children (3,462 girls, 50.9%) who completed the psychotic experiences interview. Measurements and Results: Children who were reported by their mothers as experiencing frequent nightmares between 2.5 and 9 y of age were more likely to report psychotic experiences at age 12 y, regardless of sex, family adversity, emotional or behavioral problems, IQ and potential neurological problems (odds ratio (OR) = 1.16, [95% confidence intervals (CI) = 1.00, 1.35], P = 0.049). Children reporting any of the parasomnias at age 12 y also had higher rates of concurrent psychotic experiences than those without such sleeping problems, when adjusting for all confounders (OR = 3.62 [95% CI = 2.57, 5.11], P < 0.001). Difficulty getting to sleep and night waking were not found to be associated with psychotic experiences at age 12 y when controlling for confounders. Conclusion: Nightmares and night terrors, but not other sleeping problems, in childhood were associated with psychotic experiences at age 12 years. These findings tentatively suggest that arousal and rapid eye movement forms of sleep disorder might be early indicators of susceptibility to psychotic experiences.

Objective To analyse the circumstances of fatal and non-fatal mountain hiking accidents caused by falls. Methods The study was designed as a retrospective analysis. Mountain hiking accidents caused by falls were documented during a 9-year period (2006–2014). After screening of all data for potential exclusion criteria the final sample size of 5368 accidents and 5665 victims was included into the analyses. Main outcome measures were details about accidents, victims, type of trail and surface. Results The annual number of accidents showed a continuous increase from 467 in 2006 to 700 in 2014. In total, 5.8% of all victims died during the 9-year period. 75.3% of the hikers fell during descent and 80.9% of the victims had their accident on a marked hiking trail or small path. The sex ratio for non-fatal accidents was 55% female and 45% male; for fatal accidents the female-to-male ratio was 28%:72%. Mean age of all victims was 52.5±17.5 years and victims of fatalities were about 5 years older compared with victims of non-fatal accidents (57.5±16.5 vs 52.2±17.5 years, P<0.01). Conclusion Descent is the most risky part for accidents caused by falls during mountain hiking. Male hikers are at greater risk for fatalities independent of age and this is associated with accidents occurring in pathless terrain. The death rate from falls was 6%. We recommend a critical self-assessment of the individual capabilities and mountain hiking skills and adequate planning of the hiking tours for mountain hikers. PMID:29259815

This study reports the results of a statewide survey of restraint use by 4-8-year-old children in Michigan conducted between July 13 and 29, 2004. In this study, 3420 4-8-year-old children were observed traveling in passenger cars, vans/minivans, sport-utility vehicles, and pickup trucks. Restraint use was estimated for children traveling in all vehicles combined, as well as for each vehicle type separately. Children's restraint use was also calculated by the sex, age, and belt use of the driver. Separate estimates were also made of the restraint use of 4-8-year-old children by the combination of sex and belt use of the driver. Overall, 8.6 +/- 5.9% of 4-8-year-old children were seated in a booster seat, 48.8 +/- 10.3% were wearing a safety belt, 5.1 +/- 3.4% were seated in a child safety seat, and the remaining 37.5 +/- 11.5% were traveling completely unrestrained. When examining the rates by vehicle type, booster seat use was highest among children riding in sport-utility vehicles and lowest for those in pickup trucks. Surprisingly, children riding in passenger cars were more likely to be completely unrestrained than those in any other type of vehicle. While the sex of the driver did not seem to influence the restraint use of target-aged children, the driver's age did seem to have an effect. Booster seat use was quite low (0.6%) for children traveling with a driver over the age of 60, compared to 7.0 and 9.1% for those riding with drivers 16-29 and 30-59 years of age, respectively. The safety belt use of the driver also had a substantial influence on children's restraint use. Irrespective of driver sex, children riding with belted drivers were traveling in booster seats about 10% of the time, while those riding with unbelted drivers were only in booster seats 1-2% of the time.

Objective: To investigate the change in mortality of congenital malformation in children aged <5 years in Beijing from 2006 to 2015. Methods: Using the death surveillance data in children aged <5 years in Beijing from 2006 to 2015, which was collected from the real-time surveillance network, we calculated the area and age distributions of the mortality of congenital malformation in children aged <5 years in Beijing. Meanwhile, the variations of age, time and space in the causes of deaths were discussed. Results: The mortality rate of congenital malformation in the children s decreased from 1.909‰ in 2006 to 0.703‰ in 2015, the decrease rate was 63.17 % . The decrease rate was highest in neonates (71.50 % ) ( χ (2)=57.993, P <0.01). Expect urban area ( χ (2)=3.384, P >0.05), the mortality rates of congenital malformation in the children showed a downward trend in outer suburban area and suburban area ( χ (2) =40.637 and 50.646, P <0.01). The proportion of the children died of congenital malformation decreased from 32.97 % in 2006 to 23.24 % in 2015, which mainly occurred in infancy and neonatal period ( χ (2)=9.395 and 4.354, P <0.05). The constituent ratios of the children died of neural tube defects, respiratory system abnormalities and other abnormalities decreased significantly ( χ (2)=13.478, 7.358, 7.912 and 10.074, P <0.01). The constituent ratios of children died of chromosomal abnormality, multiple malformations and digestive tract abnormality didn' t decreased significantly ( P >0.05). In the leading causes of deaths from congenital malformation, the mortality of congenital heart disease, neural tube defects and digestive tract atresia decreased obviously ( χ (2)=70.868, 18.431 and 9.225, P <0.01), except biliary atresia ( χ (2)= 1.407, P >0.05). There was an obvious area specific difference between the deaths of congenital heart disease and the deaths of neural tube defects, the mortality was higher in outer suburbs than in suburban and urban

The study aim was to investigate the association between prenatal exposure to endocrine disrupting chemicals (EDCs) and the body composition of 7 to 9 year old Flemish children. The subjects were 114 Flemish children (50% boys) that took part in the first Flemish Environment and Health Study (2002–2006). Cadmium, PCBs, dioxins, p,p′-DDE and HCB were analysed in cord blood/plasma. When the child reached 7–9 years, height, weight, waist circumference and skinfolds were measured. Significant associations between prenatal exposure to EDCs and indicators of body composition were only found in girls. After adjustment for confounders and covariates, a significant negative associationmore » was found in girls between prenatal cadmium exposure and weight, BMI and waist circumference (indicator of abdominal fat) and the sum of four skinfolds (indicator of subcutaneous fat). In contrast, a significant positive association (after adjustment for confounders/covariates) was found between prenatal p,p′-DDE exposure and waist circumference as well as waist/height ratio in girls (indicators of abdominal fat). No significant associations were found for prenatal PCBs, dioxins and HCB exposure after adjustment for confounders/covariates. This study suggests a positive association between prenatal p,p′-DDE exposure and indicators of abdominal fat and a negative association between prenatal cadmium exposure and indicators of both abdominal as well as subcutaneous fat in girls between 7 and 9 years old. - Highlights: • Associations between prenatal contaminant exposure and anthropometrics in children. • Significant association only found in girls. • No significant associations found for prenatal PCBs, dioxins and HCB exposure. • Girls: negative association between cadmium and abdominal and subcutaneous fat. • Girls: positive association between p,p′-DDE and indicators of abdominal fat.« less

To determine whether parental smoking increased the risk of hospitalization among children aged less than 2 years. Case-reference study conducted from April 1995-May 1996. The group of cases was composed of 40% of all the children aged 2 years or less years admitted to our hospital (n=392). The reference population was composed of 15% of the live newborns in the same the hospital (n=493). The information was obtained by face-to-face interview after delivery in both populations and by telephone interview or postal survey and was completed in the reference population one year after delivery. Maternal smoking increased the risk of hospitalization for lower respiratory illness (adjusted RR - 1.79; 95% CI = 1.03-3.11). Moreover, the risk of hospitalization for upper or lower respiratory illness, lower respiratory illness and bronchiolitis was increased when the mother smoked more than 19 cigarettes per day. The results were adjusted for confounding factors such as prenatal age, ethnic group, maternal education, social class, breastfeeding and hospitalization of the newborn. Parental smoking, specifically maternal smoking, affects children's health, increasing the risk of hospitalization for respiratory illness in the first 2 years of life.

Our objective was to determine scores on tests of neurocognitive functioning in children diagnosed with diabetes before age 10 years and to determine the association of age of diagnosis, duration of diabetes, subtle hypoglycemia, severe hypoglycemia, and history of hypoglycemic seizures with these neurocognitive test scores. Fifty-five of 62 eligible patients with a mean age of 7.9 +/- 1.6 years followed in our center were given the Woodcock-Johnson Psychoeducational Battery, Beery Developmental Test of Visual-Motor Integration, Finger Tapping, Grooved Pegboard, and Verbal Selective Reminding tests to evaluate the following domains: memory/attention, visual-perceptual, broad cognitive function, academic achievement, and fine motor speed/coordination. Fifteen age-matched siblings served as controls. Twenty-seven subjects were less than 5 years of age when diagnosed with diabetes, the mean age at diagnosis was 4.5 +/- 2.1 years of age, and mean diabetes duration was 2.6 +/- 2.0 years. Eighteen patients had a history of severe hypoglycemia, eight of whom had hypoglycemic seizures. The mean HbA1c was 7.8 +/- 1.1% for the year prior to testing. Our results showed that the overall mean scores for the extensive neurocognitive battery were within the normal range and were comparable to the scores of the age-matched sibling controls. Age of diagnosis and duration of diabetes did not relate to neurocognitive test results. Mean HbA1c had a negative association with some tests of memory/attention (p < 0.03-0.04) and academic achievement (p < 0.005-0.03), while number of blood glucose levels less than mg/dL had a positive association with memory/attention (p < 0.004-0.04), verbal comprehension (p < 0.03) and academic achievement (p < 0.018-0.05). There was no association of neurocognitive test scores with severe hypoglycemia, but subjects with history of hypoglycemic seizures had a decrease in scores on tests assessing memory skills (p < 0.03) including short term memory and

To explore the backpack load as a percentile of body weight (BW) and its impact on ventilatory function including tidal volume (Vt), vital capacity (VC), forced vital capacity (FVC), forced expiratory volume in one second (FEV1), FEV1/FVC, peak expiratory flow (PEF), and maximum voluntary ventilation (MVV) among 9-12 year old Saudi girls. This is a prospective, experimental study of 91 Saudi girls aged between 9-12 years from primary schools in Riyadh, Saudi Arabia. The study took place in King Saud University, Riyadh, Saudi Arabia between April 2012 and May 2012. Ventilatory function was measured under 2 conditions: a free standing position without carrying a backpack, and while carrying a backpack. The backpack load observed was 13.8% of the BW, which is greater than the recommended limit (10% BW). All values of ventilatory function were significantly reduced after carrying the backpack (p<0.001) with the exception of FEV1/FVC (p>0.178). The reduction was observed even with the lowest backpack load (7.4% BW). A significant reduction was reported for most of the ventilatory function parameters while carrying the backpack. This reduction was apparent even with the least backpack load (7.4% BW) carried by the participants. This study recommends that the upper safe limit of backpack load carried by Saudi girls aged 9-12 years should be less than 7.4% of BW.

Chronic functional constipation with or without encopresis is a common problem in the pediatric population, and the prevalence of encopresis may be underestimated. The aim of this study was to assess the prevalence and risk factors for overflow incontinence in patients with chronic constipation seen at a pediatric gastroenterology consultation. A retrospective study of 270 files of patients seen between 1997 and 2012 was conducted, and a classification according to Rome III criteria was done. Among 145 (53.7%) boys and 125 (46.2%) girls, 117 had overflow incontinence (43.3%) - 41 (35%) girls and 76 (65%) boys. The first symptoms of chronic constipation appeared at a median age of 30 and 33 months in encopretic and 16 and 12 months in nonencopretic girls and boys, respectively. The first specialized consultation took place after a median disease duration of 26.5 and 24 months in encopretic and 16 and 9 months in nonencopretic girls and boys, respectively. A history of stool retention and the presence of scybala at examination, but not of pain at defecation or anal fissure, were associated with encopresis. The onset of chronic constipation after the age of 2 years, a longer disease duration, male gender, and a history of stool retention were seen as risk factors for the development of encopresis in patients with chronic functional constipation. © The Author(s) 2014.

Several recent studies have reported that favorable clinical results and a high level of patient satisfaction can generally be obtained with no increased risk of complications after single-bundle anterior cruciate ligament (ACL) reconstruction performed in patients >40 years of age. However, no studies have yet clarified the age-based differences in clinical outcomes after double-bundle reconstruction. To compare clinical outcomes after double-bundle ACL reconstruction using hamstring tendon hybrid grafts between patients in 2 different age groups: ≥40 years and <40 years. Cohort study; Level of evidence, 3. A retrospective study was conducted using 96 patients (48 men, 48 women ; mean age, 37 years) who underwent unilateral ACL reconstruction between 2008 and 2011. These patients were divided into 2 groups: group M included patients ≥40 years of age (n = 40 patients), and group Y included patients <40 years of age (n = 56 patients). All patients underwent the same anatomic double-bundle ACL reconstruction procedure. Clinical outcomes were evaluated at 2 years after surgery. Tunnel enlargement was also evaluated by computed digital radiography at 1 week and 2 years after surgery. Mean postoperative side-to-side differences in anterior laxity were 0.5 ± 1.9 mm and 1.2 ± 1.5 mm in groups M and Y, respectively; there was a significant difference between the 2 groups ( P = .039). There were no significant differences between the groups in Lysholm knee scores, International Knee Documentation Committee (IKDC) scores, or peak muscle torque of the hamstring. On the other hand, peak muscle torque of the quadriceps was significantly lower in group M (81%) than in group Y (89%) ( P = .025). With respect to femoral tunnel enlargement, the posterolateral tunnel in group M was significantly larger than that in group Y on anteroposterior and lateral radiographs ( P = .015 and P = .002, respectively). Equivalent clinical outcomes were seen between the 2 age groups after

Background: This study assessed whether the benefits of a 2-year longitudinal non-randomised school-based physical activity (PA) intervention programme to reduce overweight and obesity were still apparent two years after completion of the controlled intervention. Methods: The study involved 84 girls (G) and 92 boys (B) aged 10–12 years who had participated in the PA intervention in 2006–2008 as 6- to 9-year olds and were included in the intervention (I) (43 G and 45 B) and the control (C) groups (41 G and 47 B). Participants’ overweight/obesity was assessed using the percentile graph of Body Mass Index (BMI) from the World Health Organization for girls and boys aged 5–19. Logistic regression (Enter method) determined the overweight/obesity occurrence in a follow-up measurement (2010) two years after completion of the controlled intervention was used. Results: Two years after the controlled PA intervention had finished, the intervention children were less likely to be overweight/obese than the control children (2.3%GI vs. 17.1%GC, 6.7%BI vs. 23.4%BC, odds ratio: 0.25; 95% confidence interval: 0.12; 0.53; p < 0.001). Conclusions: The current study indicates favourable effects of an everyday school-based PA intervention programme on lower overweight/obesity incidence, which was maintained two years after the end of the direct involvement of the researchers.

Television viewing through ages 2-5 years and bullying involvement in early elementary school

PubMed Central

2014-01-01

Background High television exposure time at young age has been described as a potential risk factor for developing behavioral problems. However, less is known about the effects of preschool television on subsequent bullying involvement. We examined the association between television viewing time through ages 2-5 and bullying involvement in the first grades of elementary school. We hypothesized that high television exposure increases the risk of bullying involvement. Method TV viewing time was assessed repeatedly in early childhood using parental report. To combine these repeated assessments we used latent class analysis. Four exposure classes were identified and labeled “low”, “mid-low”, “mid-high” and “high”. Bullying involvement was assessed by teacher questionnaire (n = 3423, mean age 6.8 years). Additionally, peer/self-report of bullying involvement was obtained using a peer nomination procedure (n = 1176, mean age 7.6 years). We examined child risk of being a bully, victim or a bully-victim (compared to being uninvolved in bullying). Results High television exposure class was associated with elevated risks of bullying and victimization. Also, in both teacher- and child-reported data, children in the high television exposure class were more likely to be a bully-victim (OR = 2.11, 95% CI: 1.42-3.13 and OR = 3.68, 95% CI: 1.75-7.74 respectively). However, all univariate effect estimates attenuated and were no longer statistically significant once adjusted for maternal and child covariates. Conclusions The association between television viewing time through ages 2-5 and bullying involvement in early elementary school is confounded by maternal and child socio-demographic characteristics.

Mammography is recommended and is cost-effective for women aged 50 to 69 years, but the value of continuing screening mammography after age 69 years is not known. In particular, older women with low bone mineral density (BMD) have a lower risk of breast cancer and may benefit less from continued screening. To compare life expectancy and cost-effectiveness of screening mammography in elderly women based on 3 screening strategies. Decision analysis and cost-effectiveness analysis using a Markov model. General population of women aged 65 years or older. The analysis compared 3 strategies: (1) Undergoing biennial mammography from age 65 to 69 years; (2) undergoing biennial mammography from age 65 to 69 years, measurement of distal radial BMD at age 65 years, discontinuing screening at age 69 years in women in the lowest BMD quartile for age, and continuing biennial mammography to age 79 years in those in the top 3 quartiles of distal radius BMD; and (3) undergoing biennial mammography from age 65 to 79 years. Deaths due to breast cancer averted, life expectancy, and incremental cost-effectiveness ratios. Compared with discontinuing mammography screening at age 69 years, measuring BMD at age 65 years in 10000 women and continuing mammography to age 79 years only in women with BMD in the top 3 quartiles would prevent 9.4 deaths and add, on average, 2.1 days to life expectancy at an incremental cost of $66773 per year of life saved. Continuing mammography to age 79 years in all 10000 elderly women would prevent 1.4 additional breast cancer deaths and add only 7.2 hours to life expectancy at an incremental cost of $117689 per year of life saved compared with only continuing mammography to age 79 years in women with BMD in the top 3 quartiles. This analysis suggests that continuing mammography screening after age 69 years results in a small gain in life expectancy and is moderately cost-effective in those with high BMD and more costly in those with low BMD.

The HealthNuts study previously reported interim prevalence data showing the highest prevalence of challenge-confirmed food allergy in infants internationally. However, population-derived prevalence data on challenge-confirmed food allergy and other allergic diseases in preschool-aged children remain sparse. This study aimed to report the updated prevalence of food allergy at age 1 year from the whole cohort, and to report the prevalence of food allergy, asthma, eczema, and allergic rhinitis at age 4 years. HealthNuts is a population-based cohort study with baseline recruitment of 5276 one-year-old children who underwent skin prick test (SPT) to 4 food allergens and those with detectable SPT results had formal food challenges. At age 4 years, parents completed a questionnaire (81.3% completed) and those who previously attended the HealthNuts clinic at age 1 year or reported symptoms of a new food allergy were invited for an assessment that included SPT and oral food challenges. Data on asthma, eczema, and allergic rhinitis were captured by validated International Study of Asthma and Allergies in Childhood questionnaires. The prevalence of challenge-confirmed food allergy at age 1 and 4 years was 11.0% and 3.8%, respectively. At age 4 years, peanut allergy prevalence was 1.9% (95% CI, 1.6% to 2.3%), egg allergy was 1.2% (95% CI, 0.9% to 1.6%), and sesame allergy was 0.4% (95% CI, 0.3% to 0.6%). Late-onset peanut allergy at age 4 years was rare (0.2%). The prevalence of current asthma was 10.8% (95% CI, 9.7% to 12.1%), current eczema was 16.0% (95% CI, 14.7% to 17.4%), and current allergic rhinitis was 8.3% (95% CI, 7.2% to 9.4%). Forty percent to 50% of this population-based cohort experienced symptoms of an allergic disease in the first 4 years of their life. Although the prevalence of food allergy decreased between age 1 year and age 4 years in this population-based cohort, the prevalence of any allergic disease among 4-year-old children in Melbourne

To examine Chinese American children's behaviors, food preferences, and cultural influences on their diet. Qualitative individual interviews using constructs from the proposed model of dietary acculturation. Community centers and Chinese schools in Houston, TX. Twenty-five Chinese American children aged 9-13 years. Diet, favorite restaurants, and parents' cooking and grocery shopping habits. Content analysis and thematic data analysis to identify code categories and themes. Coders also identified patterns based on demographic and acculturation factors. Overall, participants described their diets and associated behaviors as Asian and non-Asian. Key themes included preference for Asian and non-Asian foods; consumption of non-Asian foods for breakfast and lunch, but Asian foods for dinner; infrequent dining at restaurants; grocery shopping at Asian and non-Asian stores; and familial influences on diet. Acculturated children and children of higher socioeconomic status appeared to prefer and consume a more Westernized/non-Asian diet. Results illustrate that Chinese American children in this study practiced both Asian and non-Asian dietary behaviors. Findings corroborated existing acculturation research with parents and caregivers; supported constructs in the model of dietary acculturation; and provide guidance for research and programs related to dietary behaviors, determinants, and culture among this population.
