Project description:To determine the prevalence of uncorrected refractive errors (URE) among children 3-10 years and to affirm the necessity of a national school-based visual screening program for school-aged children. Methods: This retrospective cross-sectional study was conducted in Medina, Saudi Arabia in 2015. Children were selected through a multistage stratified random sampling from 8 kindergarten and 8 primary schools. Those included were screened to diagnose UREs using a visual acuity chart and an auto refractometer according to American guidelines. The prevalence and types of UREs were estimated. Results: Of the 2121 children enumerated, 1893 were examined, yielding a response rate of 89.3%. The prevalence of UREs was 34.9% (95% CI = 32.8%-37.1%), with significant differences in different age groups. The prevalence of astigmatism (25.3%) was higher compared to that of anisometropia (7.4%), hypermetropia (1.5%), and myopia (0.7%). Risk of uncorrected refractive error was positively associated with age, and this was noted in astigmatism, myopia, and anisometropia. In addition, the risk of hypermetropia was associated with boys and that of myopia was associated with girls. Conclusions: The prevalence of UREs, particularly astigmatism, was high among children aged 3-10 years in Medina, with significant age differences. Vision screening programs targeting kindergarten and primary schoolchildren are crucial to lessen the risk of preventable visual impairment due to UREs.

Project description:Schools are an important setting for interventions to improve mental health. There is growing evidence that school climate - sometimes expressed as the perceptions that children have about the relationships, safety, values, and beliefs within their school - can impact child mental health. Poor child mental health is associated with feelings of distress as well deficits in functioning. However, while most studies have focused on school climate, climate at lower levels of nesting, including year group, may be important. Cross-sectional data on emotional and behavioural difficulties from 32,606 children in primary schools in Wales (ages 7-11, year groups 3-6) were collected via a school survey, delivered online and within the classroom environment to all children who consented, and analysed using multilevel modelling. Models were then extended to consider how aggregated measures of year group and school climate are associated with mental health outcomes. The unadjusted variance partition coefficients (VPCs) indicated that 2.8% of the variance in emotional difficulties and 3.2% in behavioural difficulties were attributable to differences in the year group, while school-level differences represented 2.4% and 3.5%, respectively. More positive year group and school climate were associated with more positive mental health outcomes. School and year group climate are independently associated with primary school children's mental health. Interventions to support mental health should aim to optimise the whole school climate, as well as climate within year group clusters.Supplementary informationThe online version contains supplementary material available at 10.1007/s12187-024-10213-7.

Project description:Discrimination is a type of social adversity defined as unfair treatment and prejudice against individuals due to membership of a specific group. Discrimination has been linked to several age-related outcomes such as cognitive decline, inflammation, and cardiovascular disease. However, the molecular drivers to these observations are poorly understood. Social adverse factors have been associated with proinflammatory and interferon gene expression, a phenomenon described as Conserved Transcriptome Response to Adversity. It is not known whether there are additional genes whose transcription is associated with exposure to discrimination among both African American and White adults. In this study, we have examined how perceived discrimination in African American and White adults affects genome-wide transcriptome differences using RNA sequencing. Perceived discrimination was measured based on responses to lifetime discrimination and racial discrimination questionnaires. Differential gene expression and pathway analysis was conducted in a cohort (N=59) stratified by race, sex, and discrimination exposure. We found that there were 28 significantly differentially expressed genes associated with high discrimination exposure in African American adults when compared to White adults with high discrimination exposure. The most significantly upregulated genes among African Americans with high discrimination exposure were related to immune function immunoglobulin lambda variable 2-11 (IGLV2-11), S100 calcium binding protein B (S100B), immunoglobulin kappa variable 3-20 (IGKV3-20), immunoglobulin kappa variable 4-1 (IGKV4-1); the most significantly downregulated genes were associated with immune modulation and cancer, lung cancer associated transcript 1 (LUCAT1), thrombospondin 1 (THBS1), and actin related protein 2/3 complex inhibitor (ARPIN). In addition, the most significantly upregulated Gene Ontology (GO) biological process among African American men with high exposure to discrimination compared to White male adults with high exposure to discrimination was regulation of cytokine biosynthetic processes. Conversely, immune response was the most significantly downregulated GO biological process among African American women with high discrimination exposure compared White women with high discrimination exposure. Understanding the biological pathways through which adverse social factors like discrimination affect gene expression will be critical in advancing knowledge of age-related health disparities.

Project description:OBJECTIVES:To describe the objectively measured levels of physical activity (PA) and sedentary time in a nationally representative sample of 10-11-year-old children, and compare adherence estimates to the UK PA guidelines using two approaches to assessing prevalence. DESIGN:Nationally representative longitudinal cohort study. SETTING:Scotland wide in partnership with the Growing up in Scotland (GUS) study. Data collection took place between May 2015 and May 2016. PARTICIPANTS:The parents of 2402 GUS children were approached and 2162 consented to contact. Consenting children (n=1096) wore accelerometers for 8 consecutive days and 774 participants (427 girls, 357 boys) met inclusion criteria. PRIMARY AND SECONDARY OUTCOME MEASURES:Total PA (counts per minute, cpm); time spent sedentary and in moderate-to-vigorous PA (MVPA); proportion of children with ≥60 min MVPA on each day of wear (daily approach); proportion of children with ≥60 min of MVPA on average across days of wear (average approach)-presented across boys and girls, index of multiple deprivation and season. RESULTS:Mean PA level was 648 cpm (95% CI, 627 to 670). Children spent 7.5 hours (7.4-7.6) sedentary/day and 72.6 min (70.0-75.3) in MVPA/day. 11% (daily) and 68% (average) of children achieved the recommended levels of PA (P<0.05 for difference); a greater proportion of boys met the guidelines (12.5% vs 9.8%, NS; 75.9% vs 59.5%, P<0.001); guideline prevalence exhibited seasonal variation. No significant socioeconomic patterning existed across any outcome measure. CONCLUSIONS:PA estimates are significantly influenced by the analytical method used to assess prevalence. This could have a substantial impact on the evaluation of interventions, policy objectives and public health investment. Existing guidelines, which focus on daily PA only may not further our understandings about the underlying construct itself. Gender differences exist within this age-group, suggesting greater investment, with particular consideration of seasonality, is needed for targeted intervention work in younger children.

Project description:Seeking shade, the use of textile sun protection and sunscreen, and protecting one's eyes by wearing sunglasses are recommended sun protection measures in children. We aimed to quantify the use of these measures as well as the prevalence of sunburn in children aged 1 to 10 years in Germany and to identify their determinants. Data collected via telephone interviews in a nationwide sample of 554 parents or caregivers in family were analyzed. Use of sunscreen was the most common measure applied (77.8%), while sunglasses were least frequently used (12.5%). The prevalence of sunburn during the past year was 21.8%, and it was positively associated with children's age. The use of sun protection measures was significantly associated with the age and skin color of the child, while characteristics and tanning behaviors of the caregivers only played a minor role. The use of sun protection measures was higher when caregivers perceived themselves as a role model (Odds Ratio (OR) = 4.33, p < 0.001). Our nationwide data show that there remains a need for the improved use of sun protection measures, especially in children aged 7 to 10 years. In educational material, parents should be encouraged to become positive role models for their children regarding sun protection.

Project description:Perceived stress, a known risk factor for poor health, has been extensively assessed in adult populations. Yet an equivalent assessment tool for measurement of global perceived stress in children is lacking. This study aimed to develop and provide initial validation of a scale to measure perceived stress in children aged 7-11 years. Using a two-phase design, we conducted semi-structured interviews with thirteen child-parent dyads for development of items. In a sample of 123 children (age range 7-11 years, Mage = 9 years 7 months, 54.5% male) we administered the resulting Perceived Stress Scale for Kids (PeSSKi). Exploratory factor analysis of the 10-item PeSSKi yielded support for both a one-factor and a two-factor solution (negative, positive item wording). The PeSSKi was associated positively with the Penn-State Worry Questionnaire for Children (r = 0.748, p < 0.001) and negatively with the Students' Life Satisfaction Scale (r = 0.381, p < 0.001) indicating strong convergent/divergent validity respectively. Girls showed higher scores on the PeSSKi than boys with no effects observed by age. Initial psychometrics suggest the PeSSKi provides a robust scale for assessment of perceived stress in children. Further validation is needed across different child populations, over time and with physical measures of stress and health outcomes.

Project description:ObjectiveSmall increases in smoking restrictions in cars and homes were reported after legislation prohibiting smoking in public places. Few studies examine whether these changes continued in the longer term. This study examines changes in restrictions on smoking in cars and homes, and child exposure to secondhand smoke (SHS) in these locations, since 2008 postlegislation surveys in Wales.SettingState-maintained primary schools in Wales (n=75).ParticipantsChildren aged 10-11 years (year 6) completed CHETS (CHild exposure to Environmental Tobacco Smoke) Wales surveys in 2007 (n=1612) and 2008 (n=1605). A replication survey (CHETS Wales 2) was conducted in 2014, including 1601 children.Primary outcome variableChildren's reports of whether smoking was allowed in their car or home and exposure to SHS in a car or home the previous day.ResultsThe percentage of children who reported that smoking was allowed in their family vehicle fell from 18% to 9% in 2014 (OR=0.42; 95% CI 0.33 to 0.54). The percentage living in homes where smoking was allowed decreased from 37% to 26% (OR=0.30; 95% CI 0.20 to 0.43). Among children with a parent who smoked, one in five and one in two continued to report that smoking was allowed in their car and home. The percentage reporting SHS exposure in a car (OR=0.52; 95% CI 0.38 to 0.72) or home (OR=0.44; 95% CI 0.36 to 0.53) the previous day also fell. Children from poorer families remained less likely to report smoking restrictions.ConclusionsSmoking in cars and homes has continued to decline. Substantial numbers of children continue to report that smoking is allowed in cars and homes, particularly children from poorer families. A growing number of countries have legislated, or plan to legislate, banning smoking in cars carrying children. Attention is needed to the impact of legislation on child health and health inequalities, and reducing smoking in homes.

Project description:Anaemia control programmes in India are hampered by a lack of representative evidence on anaemia prevalence, burden and associated factors for adolescents. The aim of this study was to: (1) describe the national and subnational prevalence, severity and burden of anaemia among Indian adolescents; (2) examine factors associated with anaemia at national and regional levels. Data (n = 14,673 individuals aged 10-19 years) were from India's Comprehensive National Nutrition Survey (CNNS, 2016-2018). CNNS used a multistage, stratified, probability proportion to size cluster sampling design. Prevalence was estimated using globally comparable age- and sex-specific cutoffs, using survey weights for biomarker sample collection. Burden analysis used prevalence estimates and projected population from 2011 Census data. Multivariable logistic regression models were used to analyse factors (diet, micronutrient deficiencies, haemoglobinopathies, sociodemographic factors, environment) associated with anaemia. Anaemia was present in 40% of girls and 18% of boys, equivalent to 72 million adolescents in 2018, and varied by region (girls 29%-46%; boys 11%-28%) and state (girls 7%-62%; boys 4%-32%). Iron deficiency (ferritin < 15 μg/L) was the strongest predictor of anaemia (odds ratio [OR]: 4.68, 95% confidence interval [CI]: [3.21,6.83]), followed by haemoglobinopathies (HbA2 > 3.5% or any HbS) (OR: 2.81, 95% CI: [1.66,4.74]), vitamin A deficiency (serum retinol <20 ng/ml) (OR: 1.86, 95% CI: [1.23,2.80]) and zinc deficiency (serum zinc < 70 μg/L) (OR: 1.32, 95% CI: [1.02,1.72]). Regional models show heterogeneity in the strength of association between factors and anaemia by region. Adolescent anaemia control programmes in India should continue to address iron deficiency, strengthen strategies to identify haemoglobinopathies and other micronutrient deficiencies, and further explore geographic variation in associated factors.

Project description:BackgroundAlcohol abuse is not only harmful to the consumer but may also negatively impact individuals in the drinker's social environment. Alcohol's harm to others is vital to consider when calculating the true societal cost of alcohol use. Children of parents who have alcohol use disorder tend to have an elevated risk of negative outcomes regarding, e.g., health, education, and social relationships. Research on the general youth population has established a link between parental drinking and offspring alcohol use. However, there is a lack of knowledge regarding other outcomes, such as health. The current study aimed to investigate the associations between parental drinking and children's psychological and somatic complaints, and perceived stress.MethodsData were derived from a nationally representative sample, obtained from the 2010 Swedish Level-of-Living survey (LNU). Parents and adolescents (ages 10-18) living in the same households were interviewed independently. The final study sample included 909 adolescents from 629 households. The three outcomes, psychological and somatic complaints and perceived stress, were derived from adolescents' self-reports. Parents' self-reports of alcohol use, both frequency and quantity, were used to categorise adolescents as having abstaining, low-consuming, moderate-drinking, or heavy-drinking parents. Control variables included adolescents' gender, age, family structure, and household socioeconomic status. Linear and binary logistic regression analyses were performed.ResultsParental heavy drinking was more common among adolescents living in more socioeconomically advantaged households and among adolescents living with two custodial parents or in reconstituted families. Adolescents with heavy-drinking parents reported higher levels of psychological and somatic complaints and had an increased likelihood of reporting stress, compared with those having moderate-drinking parents. These associations remained statistically significant when adjusting for all control variables.ConclusionThe current study's results show that parental alcohol consumption is associated with poorer offspring adolescent health. Public health policies that aim to reduce parental drinking or provide support to these adolescents may be beneficial. Further studies investigating the health-related outcomes among young people living with heavy-drinking parents in the general population are needed to gain more knowledge about these individuals and to implement adequate public health measures.
