ObjectivesIn the present study, we examined the relation between socioeconomic status (SES) and the physiological distribution of iron-related blood parameters.DesignThis is a cross-sectional analysis of longitudinal population-based cohort study.SettingBased on a sample of healthy participants from a German research centre, various blood parameters and values of clinical examinations and questionnaires were collected.ParticipantsA total of 1206 healthy volunteers aged 2.5 to 19 years, one child per family randomly selected, were included.Primary and secondary outcome measuresAssociations between the SES of children by Winkler-Stolzenberg Index (WSI) and its dimensions (income, education, occupation) and iron-related blood parameters (haemoglobin, ferritin and transferrin) were analysed by linear regression analyses. Gender and pubertal stage were included as covariables. Additionally, associations between SES of children by WSI and physical activity (side-to-side jumps, push-ups) as well as body mass index (BMI) were analysed by linear regression analyses.ResultsChildren with high WSI or family income showed significantly increased z-scores for haemoglobin (P=0.046; P<0.001). Children with increased WSI or family income showed significantly lower z-scores for transferrin (P<0.001). There was a significant correlation between haemoglobin and gender (P<0.001) and between transferrin and pubertal stage (P=0.024). Furthermore, physical activity was positively correlated and BMI was negatively correlated with WSI (P<0.001).DiscussionOur data show an association between SES and the distribution of iron-dependent parameters. Lower SES is correlated with lower values for haemoglobin and higher values for transferrin. Furthermore, we demonstrate that physical activity and BMI are associated with SES. Whereas higher SES is correlated with higher values for physical activity and lower BMI. Our parameters are standardised as z-scores with the advantages that the results are comparable across different age groups and present physiological courses.Trial registration numberNCT02550236; Results.

Caregiving Responsibility

Abstract Background While leisure time physical activity (LTPA) has been linked to a myriad of health benefits, many individuals do not get enough LTPA. In this study, we investigated how caregiving responsibilities (for children, adults under age 65, and adults over age 65) affected components of LTPA including exercise, walking, gardening, and housework in a population of manufacturing workers. Methods A cross-sectional study was performed among 857 manufacturing workers who completed a survey assessing caregiving responsibility and LTPA. Linear regression analyses were used to test for associations between caregiving and LTPA. Results We observed that caregivers for children reported significantly (p < 0.05) fewer hours of exercise and walking, but more hours of housework, than non-caregivers. We observed no association between caregiving for adults under age 65 or adults aged 65 and older and exercise or walking. Caring for adults under age 65 was associated with a significant (p < 0.05) increase in hours spent gardening, and caring for adults aged 65 and older was associated with a significant increase in hours spent performing housework. Conclusions We identified associations between caregiving and physical activity in a population of manufacturing workers. Our results support the development of targeted interventions to promote health in working caregiver populations.

BACKGROUND: Low Health Literacy (HL) and Nutrition Literacy (NL) are associated with serious negative health outcomes. OBJECTIVES: The aim of this study was to investigate certain lifestyle factors and obesity, in relation to HL and NL. METHODS: This cross-sectional study was conducted in the urban area of the Attica region, in Greece. The sample consisted of 1281 individuals, aged ≥18 years. HL, NL sociodemographic characteristics and lifestyle factors (physical activity, smoking status, alcohol consumption,) were assessed. Mann-Whitney U, the Kruskall Wallis, Pearson chi-square tests and multiple linear regression models were used. RESULTS: Linear regression analysis has shown that smoking, alcohol consumption and physical activity, were associated with HL levels (–1.573 points for ex-smokers in comparison to smokers, p = 0.035, –1.349 points for alcohol consumers in comparison to non-consumers, p = 0.006 and 1.544 points for physically active individuals to non-active, p = 0.001). With respect to NL levels, it was also not associated with any of these factors. Obesity was not associated with HL and NL levels. CONCLUSIONS: Certain lifestyle factors, including physical activity, are predicting factors of HL levels, in Greek adults. The results contribute to the understanding of the relationship between lifestyle factors and HL and should be taken into account when HL policies are designed.

AbstractKnowledge about modifiable determinants of daily physical activity (PA) in patients with chronic obstructive pulmonary disease (COPD) is crucial to design effective PA interventions. The present study aimed to determine the contribution of quadriceps strength, power and endurance to daily PA in COPD. Additionally, for quadriceps endurance, we also aimed to determine to what extent the association varies according to the mode of movement (isotonic, isometric, or isokinetic). Using a multicentre cross-sectional trial design we determined the contribution of quadriceps function to daily PA (steps, sedentary time and time spent doing moderate-to-very-vigorous physical activity [MVPA]) using bivariate and partial Pearson correlation analysis (r) and multiple linear regression models (ΔR2). Pre-determined controlling factors were sex, age, body mass index (BMI), COPD-assessment test, forced expiratory volume in one second in percent of the predicted value (FEV1pred), and distance walked on the 6-minute walk test. Eighty-one patients with COPD (mean ± SD: age 67 ± 8 years, FEV1pred 57 ± 19%, daily steps 4968 ± 3319, daily sedentary time 1016 ± 305 min, and MVPA time 83 ± 45 min) were included. Small to moderate bivariate correlations (r = .225 to .452, p < .05) were found between quadriceps function and measures of PA. The best multiple linear regression models explained 38–49% of the variance in the data. Isotonic endurance was the only muscle contributor that improved all PA models; daily steps (ΔR2 = .04 [relative improvement 13%] p = .026), daily sedentary time (ΔR2 = .07 [23%], p = .005) and MVPA-minutes (ΔR2 = .08 [20%], p = .001). Isotonic endurance was also independently associated with most PA variables, even when controlling for strength, power or isometric-isokinetic endurance properties of the muscle (r = .246 to .384, p < .05). In contrast, neither strength, power, isometric-or isokinetic endurance properties of the muscle was independently associated with PA measures when controlling for isotonic endurance (r = .037 to .219, p > .05). To conclude, strength, power, and endurance properties of the quadriceps were low to moderately associated with PA in patients with COPD. Isotonic quadriceps endurance was the only quadriceps property that was independently associated with the different measures of PA after controlling for a basic set of known determinants of PA, quadriceps strength or power, or isometric or isokinetic quadriceps endurance. Future longitudinal studies should investigate its potential as a modifiable determinant of PA.

Abstract Background Life satisfaction is an important component in designing strategies to improve health outcomes in different groups of society. This study aimed to investigate the effect of subjective socioeconomic status (SSS), social capital (SC), self-rated health (SRH), and physical activity (PA) on life satisfaction (LS) in Iran. Methods This cross-sectional study was conducted on 1187 people (643 men and 544 women) lived in five western cities in Iran. The sampling method was multistage clustering. Data collection tool was a five part questionnaire including demographic characteristics, socioeconomic status ladder, social capital scale, a question to measure physical activity, and the life satisfaction scale. Data were analyzed using independent t-test, one way ANOVA, and Ordinal Logistic Regression. Result Life satisfaction was higher in married men and women compared to single and widows (p < 0.05). Among the variables included in the main model, the significant predictors were college education (− 0.500), marriage (coefficient = 0.422), age 25–34 years (coefficient = − 0.384), SRH (coefficient = 0.477), male sex (coefficient = 0.425), SSS (coefficient = 0.373), trust (coefficient = 0.115), and belonging and empathy (coefficient = 0.064). Conclusion SRH and SSS were significant predictors of life satisfaction in west Iranian society. Being married was associated with higher LS, but college education affects LS adversely.

ABSTRACT Objective: To analyze the prevalence of pressure injuries, diabetic and vasculogenic ulcers and associated factors in older adults attended in primary care. Method: A cross-sectional, analytical study with older adults attended in the Family Health Strategy in a Brazilian municipality. Data collection was performed from January to March 2016 using interviews and evaluations of injuries. The variables were submitted to the multivariate logistic regression model using the odds ratio, with their respective 95% confidence intervals and significance set at <0.05. Results: 339 older adults participated in the study. The mean age was 71.1 years, 67.3% were female, 44% were illiterate, 85% had low family income, 91.7% had underlying diseases, 37.2% had dietary restrictions, and 76.1% did not practice physical activity. The prevalence of pressure injury was 5.0%, diabetic ulcer 3.2%, and vasculogenic ulcer 2.9%. Not working and not regularly practicing physical activity increased the chances of presenting these injuries by 1.5 and 2.3 times, respectively. Being actively mobility and not having dietary restrictions were protective factors for not developing chronic wounds. Conclusion: The prevalence of injuries among older adults was high, and its occurrence is associated with socioeconomic and clinical characteristics.

Background: A wide array of Socioeconomic Status (SES) indicators show differential effects for the members of diverse social groups. Researchers know a little about the ethnic variation and the effects of family income on delay discounting which is the predictor of risk behaviors. Objectives: This study examined the effect of family income and its differences on delayed gratification between Latino and non-Latino children. Materials & Methods: In this cross-sectional analytical study, data came from wave one of the Adolescent Brain Cognitive Development (ABCD) study which included 3903 non-Latino or Latino Black or White American children who are between 9 and 10 years old. The predictor was family income. Data were collected from 21 sites in the US, in 2018. The outcome was the children’s delay discounting. We measured delay discounting, which reflected individuals’ tendency to assign less value to remote outcomes and rewards (inversely correlated with delayed gratification). Data analysis was done by linear regression in SPSS V. 22. Results: According to our pooled sample regression, higher family income was associated with lower children delay discounting (Beta=-0.05, P=0.021). We found a significant interaction between family income and ethnicity, suggesting that the association between family income and delay discounting is stronger for Latino compared with non-Latino children (Beta=-0.09, P=0.043). Conclusion: Not all ethnic disparities are due to socioeconomic status gaps. Across diverse social groups, differential returns of socioeconomic status indicators, such as family income, also contribute to ethnic disparities in health.

ABSTRACT Introduction Although the benefits of regular physical activity (PA) for adolescents are well-described in the literature, there is little evidence of the role of psychosocial aspects on levels of PA in this population. Objective To investigate the prevalence and sociodemographic factors associated with enjoyment of PA and preference for leisure-time activities in boys and girls. Methods A cross-sectional study, with 6529 adolescents (aged 15 to 19 years) enrolled in secondary education in public schools in the South of Brazil. Logistic regression was used to analyze the association between sociodemographic factors and the variables of interest, with data collection using a standardized questionnaire. Results Boys enjoyed (87.1%) and preferred (44.4%) PA more than girls (enjoyment: 79.2%; preference: 29.5%). Among the boys, enjoyment was associated with family income(OR3-5 wages=1.53; OR≥6 wages=1.62) and, among the girls, it was associated with age (OR19 years=0.28), occupational status (ORworkers=1.45), and income (OR3-5 wages=1.35). Preference was associated with age (OR19 years=2.48) and income (OR≥6 wages=0.70) among the boys and, among girls, it was associated with area of residence (ORrural=1.47) and occupation (ORworkers=1.31). Conclusion Boys (enjoyment: 87.1%; preference: 44.4%) had more positive attitudes toward PA than girls (enjoyment: 79.2%; preference: 29.5%), and some sociodemographic variables appear to be more closely associated with these attitudes than others. Enjoyment was associated with family income for boys, and with age, occupation and income for girls. Preference, in turn, was associated with age and family income for boys, and area of residence and occupational status for girls.

Obesity is defined as an increase in energy intake compared to expenditure, resulting in depletion of body fat and eventually wearing weight. The prevalence of obesity has increased sharply in the Asia Pacific region. Many factors cause obesity. Based on data obtained from the Gorontalo District Health Office in 2018, it shows that the incidence of obesity was 8.795 cases (30.9%) consisting of 1.971 men (6.9%) and 6.824 women (24.0%). Objective: To determine several factors related to the incidence of obesity in adolescents in several high schools in Gorontalo District. This type of research uses observational analytic with a cross sectional study design. The population in this study were all students of class X and XI in SMA Negeri 1 Telaga and SMA Negeri 1 Tibawa, Gorontalo Regency as many as 1.341 students. By using the sampling technique of Proportional Stratified Random Sampling as many as 171 samples. With data analysis techniques using thetest Chi Square. The results of the study of physical activity and consumption of fruits and vegetables had no relationship with the incidence of obesity in adolescents in several high schools in Gorontalo District. Meanwhile, family income has a relationship with the incidence of obesity in adolescents in several high schools in Gorontalo Regency in 2019. It is hoped that each school can increase various activities that can reduce obesity problems and can also provide education in the form of health education to students.

Abstract Background The extent to which income setting or rural and urban environments modify the association between sleep and obesity in young children is unclear. The aims of this cross-sectional observational study were to (i) describe and compare sleep in South African preschool children from rural low-income (RL), urban low-income (UL) and urban high-income (UH) settings; and (ii) test for associations between sleep parameters and body mass index (BMI). Methods Participants were preschoolers (5.2 ± 0.7y, 49.5% boys) from RL (n = 111), UL (n = 65) and UH (n = 22) settings. Height and weight were measured. Sleep, sedentary behaviour and physical activity were assessed using accelerometery. Results UL children had higher BMI z-scores (median: 0.39; interquartile range: − 0.27, 0.99) than the UH (− 0.38; − 0.88, 0.11) and RL (− 0.08; − 0.83, 0.53) children (p = 0.001). The UL children had later bedtimes (p < 0.001) and wake-up times (p < 0.001) and shorter 24 h (p < 0.001) and nocturnal (p < 0.001) sleep durations than the RL and UH children. After adjusting for age, sex, setting, SB and PA, for every hour less sleep obtained (24 h and nocturnal), children were 2.28 (95% CI: 1.28–4.35) and 2.22 (95% CI: 1.27–3.85) more likely, respectively, to belong to a higher BMI z-score quartile. Conclusions Shorter sleep is associated with a higher BMI z-score in South African preschoolers, despite high levels of PA, with UL children appearing to be particularly vulnerable.
