Abstract
While various influencing factors of overweight and obesity have been identified, the underlying mechanism remains unclear. We examined the relationships among sociodemographic, behavioral, and psychological factors on anthropometry in a multi-ethnic population with overweight and obesity. Participants (N = 251) were recruited from January to October 2022. Mean age and self-reported BMI were 31.7 ± 10.1 years and 29.2 ± 7.2 kg/m2. Participants were mostly female (52.4%) and overweight (58.2%). Multivariate multiple regression was performed using maximum likelihood estimation. Body mass index was associated with waist circumference, age, sex, race, marital status, education level, residential region, overeating habit, immediate thinking, self-regulation, and physical activity, but not anxiety, depression, or the intention to change eating habits. Final model indicated good fit: χ2 (30, N = 250) = 33.5, p = 0.32, CFI = 0.993, TLI = 0.988, RMSEA = 0.022, and SRMR = 0.041. Direct effects were found between BMI and overeating (β = 0.10, p = 0.004), race (β = -0.82, p < 0.001), marital status (β = -0.42, p = 0.001), and education level (β = -0.28, p = 0.019). Crisps (68.8%), cake (66.8%) and chocolate (65.6%) were identified as the most tempting foods. Immediate thinking indirectly increased overeating habits through poor self-regulation, although sociodemographic characteristics better predicted anthropometry than psycho-behavioral constructs.

Abstract
Abstract Perceived discrimination is a major producer of stress and social trauma and can have negative effects on the physical and mental health of those exposed to it. This study aims to analyze the direct and indirect association between perceived discrimination and physical activity, mediated by common mental disorders in adolescents. This is a cross-sectional study with 2,484 adolescents (aged 18 and 19 years old) from a cohort in São Luís, Maranhão. Structural equation models were used to verify the direct effect of perceived discrimination on physical activity (PA) and its indirect effect mediated by common mental disorders (CMD). The potential of sex to act as an effect-modifying variable was also tested. Discrimination was associated with higher levels of PA in women (SC - Standardized Coefficient direct =0.105, p-value=0.005), and indirectly associated with lower PA via CMT among men (SCindirect =-0.024, p-value=0.017) and women (SCindirect =-0.024, p-value=0.015). Our findings show the association between perceived discrimination and PA in this population of adolescents, attesting that its effects can alter health behaviors and that gender can modify the relation between these variables.

Abstract
The present study analyzed factors associated with the use of oral health services among elderly Brazilians. This was a cross-sectional study with data from the latest National Oral Health Survey (SB Brazil 2010), which considered a sample of 7,619 elderly individuals (65-74 years) for analysis. Structural Equation Modeling (SEM) was used, investigating the association between latent or observed variables, directly or mediated, in relation to the use of oral health services. Least squares estimators adjusted by mean and variance, were used by means of standardized coefficients, and standard error and confidence intervals, by applying the bootstrapping method with 1,500 iterations. Elderly individuals with a higher socioeconomic status, fewer missing teeth, and the presence of impacts of oral health conditions on their lives were directly associated with the outcome. Other factors associated with the mediated use of oral health services among elderly Brazilians included socioeconomic status, gender, age, and the use of prostheses, in addition to finding a correlation between prosthesis use and missing teeth. Tooth loss, along with other factors, played a prominent role in this study regarding the use of oral health services among elderly Brazilians, pointing to the need to expand access to dental prostheses in primary care.

Abstract
The study aimed to analyze factors associated with inflammatory biomarkers in adolescents. This was a cross-sectional study in 391 adolescents 17-18 years of age in public schools in São Luís, Maranhão State, Brazil. Three-stage random cluster sampling was performed in schools, classes, and students. Food consumption was studied with a food frequency questionnaire, and dietary patterns were extracted by principal components factor analysis. Assessment of factors associated with inflammatory biomarkers used structural equation modeling. Latent variables were constructed: socioeconomic status, which included maternal schooling, family income, and economic class; and inflammation, consisting of interleukin-1β, interleukin-6, and interleukin-8. A theoretical model was developed to assess factors associated with inflammatory biomarkers, indicating direct and indirect effects between the latent and observed variables. Three dietary patterns were identified (Western, basic Brazilian, and healthy), with 31% explained variance and the Western pattern with the largest share. No associations were found between the patterns and the latent variable inflammation (standardized coefficients = 0.281; p = 0.002). Extraction of the three patterns evidenced higher consumption of foods high in carbohydrates and fats, which are nutrients associated directly with the increase in chronic noncommunicable diseases. Excess weight was associated with higher levels of inflammatory biomarkers.

Social Determinants of Cigarette Smoking among American Women during Pregnancy. WOMEN 2021.

Abstract
Educational attainment is among the most substantial protective factors against cigarette smoking, including during pregnancy. Although Minorities’ Diminished Returns (MDRs) of educational attainment, defined as weaker protective effect of education for racial and ethnic minority groups compared to Non-Hispanic Whites, has been demonstrated in previous studies; such MDRs are not tested for cigarette smoking during pregnancy. To better understand the relevance of MDRs to tobacco use during pregnancy, this study had three aims: firstly, to investigate the association between educational attainment and cigarette smoking in pregnant women; secondly, to compare racial and ethnic groups for the association between educational attainment and cigarette smoking; and thirdly, to explore the mediating effect of poverty status on such MDRs, among American adults during pregnancy. This cross-sectional study explored a nationally representative sample of pregnant American women (n = 338), which was taken from the Population Assessment of Tobacco and Health (PATH; 2013). Current smoking was the outcome. Educational attainment was the independent variable. Region and age were the covariates. Poverty status was the mediator. Race and ethnicity were the effect modifiers. Overall, a higher level of educational attainment (OR = 0.54, p < 0.05) was associated with lower odds of current smoking among pregnant women. Race (OR = 2.04, p < 0.05) and ethnicity (OR = 2.12, p < 0.05) both showed significant interactions with educational attainment on smoking, suggesting that the protective effect of educational attainment against smoking during pregnancy is smaller for Blacks and Hispanics than Non-Hispanic Whites. Poverty status fully mediated the above interactions. In the United States, highly educated pregnant Black and Hispanic women remain at higher risk of smoking cigarettes, possibly because they are more likely to live in poverty, compared to their White counterparts. The results suggest the role that labor market discrimination has in explaining lower returns of educational attainment in terms of less cigarette smoking by racial and ethnic minority pregnant women.

Abstract
BACKGROUND Small for gestational age (SGA) birth weight, a risk factor for infant mortality and delayed child development, is associated with maternal educational attainment. Maternal tobacco smoking during pregnancy could contribute to this association. We aimed to quantify the contribution of maternal smoking during pregnancy to social inequalities in child birth weight for gestational age (GA). METHODS Data come from the French nation-wide ELFE cohort study, which included 17 155 singletons. Birth weights for GA were calculated using z-scores. Associations between maternal educational attainment, tobacco smoking during pregnancy and child birth weight for GA were ascertained using mediation analysis. Mediation analyses were also stratified by maternal pre-pregnancy body mass index. RESULTS Low maternal educational attainment was associated with an increased odd of tobacco smoking during pregnancy [adjusted OR (ORa) = 2.58 (95% CI 2.34-2.84)] as well as a decrease in child birth weight for GA [RRa = 0.94 (95% CI 0.91-0.98)]. Tobacco smoking during pregnancy was associated with a decrease in offspring birth weight for GA [RRa = 0.73 (95% CI 0.70-0.76)]. Mediation analysis suggests that 39% of the effect of low maternal educational attainment on offspring birth weight for GA was mediated by smoking during pregnancy. A more important direct effect of maternal educational attainment on child birth weight for GA was observed among underweight women [RRa = 0.82 (95% CI 0.72-0.93)]. CONCLUSIONS The relationship between maternal educational attainment and child birth weight for GA is strongly mediated by smoking during pregnancy. Reducing maternal smoking could lessen the occurrence of infant SGA and decrease socioeconomic inequalities in birth weight for GA.

Abstract
This study aimed to develop a conceptual model and to explore direct and indirect associations between paid work and life-course factors in a representative national sample of the Brazilian population 50 years and older. The analysis was based on 8,903 participants in the baseline of the Brazilian Longitudinal Study of Aging (ELSI-Brazil). The exposure variables were sociodemographic, health, work, and social interaction variables. Based on a structural equation model, paid work showed total association with lifetime social status in women (standardized coefficient - SC = 0.489) and direct association with capacity for work in men (SC = 0.527). For women alone, an indirect and negative association was observed with lifetime intense physical effort at work, via retirement (SC = -0.156). Men with paid work were more prone to social participation, measured by belonging to groups or associations (SC = 0.209). Among women, this participation was through interaction with family and friends (SC = 0.047), via capacity for work. For both men and women, lifetime health status showed an indirect and positive association (SC = 0.298 men; SC = 0.142 women) with paid work, via capacity for work. All the above-mentioned factors showed a significant association with paid work. The study's results showed that participation in the work market occurs by different mechanisms for men and women, principally considering the factors related to work and social interaction.

Abstract
Resumo A atividade física é um comportamento complexo e influenciado por variáveis sociodemográficas e clínicas. A melhor compreensão desses fatores possibilita considerar a associação deles com a atividade física. O objetivo deste estudo foi estimar os efeitos do nível socioeconômico, idade, gordura corporal e sintomas depressivos na frequência de atividade física entre adultos. Trata-se de um estudo transversal de base populacional conduzido com 808 indivíduos. Foram avaliadas as inter-relações entre as variáveis nível socioeconômico, idade, gordura corporal e sintomas depressivos no nível de atividade física total, por meio da técnica “path analysis”. Observou-se efeito direto negativo e significativo da idade (β = -0,113; p < 0,004) nos níveis de atividade física. A idade (β = 0,376; p < 0,001) influenciou a gordura corporal, com efeito positivo e significativo. Os sintomas de depressão foram influenciados negativamente pelo nível socioeconômico (β = -0,126; p < 0,001) e positivamente pela idade (β = 0,244; p < 0,001) e gordura corporal (β = 0,169; p < 0,004). O nível socioeconômico, a gordura corporal e os sintomas depressivos não influenciaram diretamente os níveis de atividade física. Concluindo, os resultados mostraram que o avançar da idade contribui para a redução da prática de atividade física.

Abstract
This study proposed the application of structural equation modeling (SEM) to investigate variables associated with preterm birth based on a theoretical model analyzed previously by hierarchical logistic regression. The data came from a population-based case-control observational study of hospital births to mothers residing in Londrina, Paraná State, Brazil (June 2006 to March 2007). For the SEM, the study considered the association between socioeconomic characteristics and psychosocial aspects pertaining to reproductive history, work and physical activity, complications during the pregnancy, and fetal characteristics. It also considered the relationship between these associations and the outcome preterm birth mediated by adequacy of prenatal care. The weighted least square mean and variance adjusted estimator (WLSMV) was used for categorical data and robust maximum likelihood (MLR) for odds ratios. Three latent variables were created: socioeconomic vulnerability, family vulnerability, and unwanted pregnancy. The effect of socioeconomic and family vulnerability and unwanted pregnancy on prematurity occurred indirectly through inadequacy of prenatal care. The proposed methodology allowed using constructs, verifying the role of mediation by inadequacy of prenatal care, and identifying the variables' direct and indirect effects on the outcome preterm birth.

Abstract
OBJECTIVE To test whether there is an association between socioeconomic status in childhood and measures of body mass index, waist circumference and the presence of overall and abdominal obesity in adult life. METHODS A cross-sectional analysis of a population-based cohort study, including a sample of adults (22-63 years old) living in Florianópolis, Southern Brazil. The socioeconomic status in childhood was analyzed through the education level of the participant's parents. Height, weight and waist circumference were measured by previously trained interviewers. Linear and logistic regressions with adjustment for confounding factors and stratification of data according to gender were used. RESULTS Of the 1,222 adults evaluated, 20.4% (95%CI 18.1-22.8) presented overall obesity and 24.8% (95%CI 22.4-27.4), abdominal obesity. The body mass index and waist circumference averages among women were, respectively, 1.2 kg/m2 (95%CI -2.3- -0.04) and 2.8 cm (95%CI -5.3- -0.2) lower among those with higher socioeconomic status in childhood. Among men, waist circumference was 3.9 cm (95%CI 1.0-6.8) higher in individuals with higher socioeconomic status in childhood. Regarding obesity, women of higher socioeconomic status in childhood had lower odds of abdominal obesity (OR = 0.56, 95%CI 0.34-0.90), and no such association was observed among men. CONCLUSIONS The socioeconomic status in childhood influences body mass index, waist circumference and obesity in adults, with a difference in the direction of association according to gender. The higher socioeconomic status among men and the lower socioeconomic status among women were associated with higher adiposity indicators.

A model of environmental correlates of adolescent obesity in the United States. J Adolesc Health 2014; 55:394-401. [PMID: 24746491 DOI: 10.1016/j.jadohealth.2014.02.022] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/30/2013] [Revised: 02/20/2014] [Accepted: 02/20/2014] [Indexed: 11/21/2022]
Abstract
PURPOSE The purpose of this study was to test a conceptual model of proximal (home) and distal (neighborhood) environmental correlates of adolescent obesity. METHODS This was a descriptive, cross-sectional study, using the 2007 National Survey of Children's Health, of 39,542 children aged 11-17 years. Structural equation modeling was used to test the fit of the model, identify direct and indirect effects of the proximal and distal environmental correlates, and determine reliabilities for latent constructs (Access to Physical Activity, Neighborhood Conditions, Social Capital Home Sedentary Behavior, and Physical Activity). RESULTS The model fitted the data well (Root Mean Square Standard Error of Approximation: .038 (90% confidence interval .038-.039), Comparative Fit Index: .950, and Tucker-Lewis Index: .934). Access to Physical Activity, Social Capital, Home Sedentary Behavior, and Physical Activity had direct effects on obesity (-.026, p = .001; .061, p < .001; .110, p < .001; and -.119, p < .001, respectively). Neighborhood Condition had indirect effects on obesity through Access to Physical Activity, Social Capital, and Home Sedentary Behavior (-.001, p = .009; .032, p < .001; and .044, p < .001, respectively). Access to Physical Activity had indirect effects on obesity through Physical Activity, Social Capital, and Home Sedentary Behavior (-.013, p < .001; -.005, p < .001; and -.005, p = .003, respectively). Home Sedentary Behavior had indirect effect on obesity through Physical Activity (.052, p <.001). CONCLUSIONS Results of this model fit to the U. S. population-based data suggest that interventions should target not only sedentary behavior and physical activity but also parent perceptions of safety, access to physical activity, and the neighborhood condition.

Abstract
This study aimed to estimate the prevalence of impact of oral health conditions on physical and psychosocial dimensions among adolescents and to identify factors associated with severity of impact. The impact of oral health status was assessed by the instrument Oral Health Impact Profile (OHIP-14). The covariates were: socioeconomic status, habits and health care, use of dental services, and normative conditions of oral health. Structural equation modeling was performed, and 15.6% of adolescents reported impact in at least one dimension of the OHIP-14. The dimensions that showed the highest prevalence of impact were psychological distress (11.8%) and physical pain (6.6%). The number of teeth needing dental treatment, number of filled teeth, and CPI significantly affected severity of impact. In this adolescent population, unfavorable socioeconomic conditions were associated with reduced use of dental services, associated in turn with precarious oral health conditions and increased severity of impact.

[PMID: 24112242 DOI: 10.1111/obr.12109] [Citation(s) in RCA: 26] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/16/2013] [Revised: 08/22/2013] [Accepted: 08/23/2013] [Indexed: 01/08/2023]
Abstract
We performed a systematic literature review on the associations between birth size and abdominal adiposity in adults, while also investigating the role of the adjustment for adult body mass index (BMI). MEDLINE, Scopus, Web of Science, LILACS and SciELO databases were searched for articles published up to February 2013. Only prospective studies were included. After screening 2,570 titles, we selected 31 publications for the narrative synthesis, of which 13 were considered to be of high methodological quality. Six main indicators of birth size were identified, and birth weight (BW) was the most extensively studied. Most studies relied on anthropometric measurements as proxies for abdominal fatness or as indicators of body fat distribution. Few studies assessed abdominal adiposity through imaging methods, generally with small sample sizes. Eleven articles could be included in the meta-analyses. BW was found to be positively associated with waist circumference in adulthood, but the association disappeared after adjustment for adult BMI. In contrast, there was no association between BW and waist-to-hip ratio, whereas a strong negative association became evident after controlling for adult BMI. In conclusion, BW seems to be associated with larger adult size in general, including both waist and hip circumferences. The marked change in coefficients after adjustment for adult BMI suggests that post-natal growth strongly affects relative central adiposity, whereas BW per se does not play a role. Given the potential impact of post-natal growth, further research is needed to identify different growth trajectories that lead to abdominal adiposity, as well as studies on interactions of foetal and post-natal growth patterns.

Evaluation of the association between maternal smoking, childhood obesity, and metabolic disorders: a national toxicology program workshop review. ENVIRONMENTAL HEALTH PERSPECTIVES 2013; 121:170-80.

Abstract
BACKGROUND An emerging literature suggests that environmental chemicals may play a role in the development of childhood obesity and metabolic disorders, especially when exposure occurs early in life. OBJECTIVE Here we assess the association between these health outcomes and exposure to maternal smoking during pregnancy as part of a broader effort to develop a research agenda to better understand the role of environmental chemicals as potential risk factors for obesity and metabolic disorders. METHODS PubMed was searched up to 8 March 2012 for epidemiological and experimental animal studies related to maternal smoking or nicotine exposure during pregnancy and childhood obesity or metabolic disorders at any age. A total of 101 studies-83 in humans and 18 in animals-were identified as the primary literature. DISCUSSION Current epidemiological data support a positive association between maternal smoking and increased risk of obesity or overweight in offspring. The data strongly suggest a causal relation, although the possibility that the association is attributable to unmeasured residual confounding cannot be completely ruled out. This conclusion is supported by findings from laboratory animals exposed to nicotine during development. The existing literature on human exposures does not support an association between maternal smoking during pregnancy and type 1 diabetes in offspring. Too few human studies have assessed outcomes related to type 2 diabetes or metabolic syndrome to reach conclusions based on patterns of findings. There may be a number of mechanistic pathways important for the development of aberrant metabolic outcomes following perinatal exposure to cigarette smoke, which remain largely unexplored. CONCLUSIONS From a toxicological perspective, the linkages between maternal smoking during pregnancy and childhood overweight/obesity provide proof-of-concept of how early-life exposure to an environmental toxicant can be a risk factor for childhood obesity.
