No research exists on how body mass index (BMI) changes with age over the full life span and social disparities therein. This study aims to fill the gap using an innovative life-course research design and analytic methods to model BMI trajectories from early adolescence to old age across 20th-century birth cohorts and test sociodemographic variation in such trajectories. We conducted the pooled integrative data analysis (IDA) to combine data from four national population-based NIH longitudinal cohort studies that collectively cover multiple stages of the life course (Add Health, MIDUS, ACL, and HRS) and estimate mixed-effects models of age trajectories of BMI for men and women. We examined associations of BMI trajectories with birth cohort, race/ethnicity, parental education, and adult educational attainment. We found higher mean levels of and larger increases in BMI with age across more recent birth cohorts as compared with earlier-born cohorts. Black and Hispanic excesses in BMI compared with Whites were present early in life and persisted at all ages, and, in the case of Black–White disparities, were of larger magnitude for more recent cohorts. Higher parental and adulthood educational attainment were associated with lower levels of BMI at all ages. Women with college-educated parents also experienced less cohort increase in mean BMI. Both race and education disparities in BMI trajectories were larger for women compared with men.

The concepts of traditional and nontraditional gender roles in Western culture, the impact of family of origin on gender role development, and different developmental theories of gender role identification are reviewed. In order to gain a more comprehensive understanding of gender role identification, the Cognitive-Active Gender Role Identification Continuum model is introduced. This model aids in the understanding of differences between cognitions and actions and levels of flexibility and rigidity that may be displayed in individuals in regard to gender roles. This model may be beneficial in understanding conflicts pertaining to gender role differences in a therapeutic setting with couples and families.

Frequent school absence is often cited as a risk factor for peer relationship problems in youngsters with chronic illnesses, but this assumption has not been subjected to quantitative empirical examination. This issue was examined in the present study by exploring the relationship between school absenteeism, peer aggression, and loneliness in adolescents with chronic illnesses. Forty-one adolescents with chronic illnesses completed a modified version of the Direct and Indirect Aggression Scale and the Asher Loneliness Scale. Details of school absences and hospitalizations were obtained from parents and school and hospital records. No evidence was found to support the notion that peer aggression and loneliness are related to absenteeism, but social aggression (for both boys and girls) and verbal aggression (more markedly for girls) were associated with loneliness. Of the group, 19% reported experiencing verbal aggression and 12% social aggression at least weekly; informal qualitative data suggesting that such aggression is often related to limited sporting ability and appearance. Interventions at both the individual and school community level are warranted.

Physical comorbidities associated with mental health conditions contribute to high health care costs. This study examined the impact of having a usual source of care (USC) for physical health on health care utilization, spending, and quality for adults with a mental health condition using Medicaid administrative data. Having a USC decreased the probability of inpatient admissions and readmissions. It decreased expenditures on emergency department visits for physical health, 30-day readmissions, and behavioral health inpatient admissions. It also had a positive effect on several quality measures. Results underscore the importance of a USC for physical health and integrated care for adults with mental health conditions.

Objectives To better understand the temporal dynamics of progression from cognitive decline to onset of dementia in the dementia-free older population in the U.S. Methods We used longitudinal data from a diverse national population-based sample of older adults (N=531) in the Aging, Demographics and Memory Study (ADAMS) from the Health and Retirement Study (HRS) with repeated measures of cognitive function and dementia diagnosis during 12 years of follow-up from 1996 to 2009. We employed joint latent class mixed models to estimate the association between cognitive change and competing risks of dementia and non-dementia death and identify heterogeneity in the age profiles of such association adjusting for baseline characteristics. Results Our analyses found three latent classes with distinct age profiles of cognitive decline and associated risk of dementia and mortality: “Rapid Cognitive Decline” (19.6%), “Moderate Progression” (44.6%), and “Optimal Cognitive Aging” (35.8%). When simultaneously accounting for cognitive trajectories and time-to-dementia/death, we also found associations of baseline covariates with slope of cognitive decline (e.g., steeper decline among non-Hispanic Blacks and more educated) and risk of dementia (e.g., greater risk for females and apolipoprotein E [APOE-4] carriers, but no difference by education level) that differ substantially from those in separate longitudinal mixed models or survival models. Discussion The differential age patterns of cognitive decline predicting dementia incidences identified in this study suggest variation in the course of cognitive aging in older adults that may inform future etiological and intervention studies.

Background: Increasing numbers of children are receiving care for behavioral health conditions in emergency departments (EDs). However, studies of mental health-related care coordination between EDs and primary and/or specialty care settings are limited. Such coordination is important because ED care alone may be insufficient for patients' behavioral health needs. Methods:We analyzed claims during the year 2014 from Truven Health Analytics MarketScan Medicaid and Commercial databases for outpatient services and prescription drugs for youth 2 to 18 years old with continuous enrollment. We applied a standard care coordination measure to insurance claims data in order to examine whether youth received a primary care or specialty follow-up visit within 7 days following an ED visit with a psychiatric diagnosis. We calculated descriptive statistics to evaluate differences in care coordination by enrollees' demographic, insurance, and healthrelated characteristics. In addition, we constructed a multivariate logistic regression model to detect the factors associated with the receipt of care coordination. Results:The total percentages of children who received care coordination were 45.8% (Medicaid) and 46.6% (private insurance). Regardless of insurance coverage type, children aged 10 to 14 years had increased odds of care coordination compared with youth aged 15 to 18 years. Children aged 2 to 5 years and males had decreased odds of care coordination. Conclusions:It is of concern that fewer than half of patients received care coordination following an ED visit. Factors such as behavioral health workforce shortages, wait times for an appointment with a provider, and lack of reimbursement for care coordination may help explain these results.

Purpose Snacking contributes to one-quarter of children’s total daily energy intake in the USA, with many snack foods being nutrient-poor and energy-dense. Snacking and sugary beverage consumption have been identified as potential contributors to childhood overweight and obesity and may play a particularly important role among children from socioeconomically disadvantaged households that generally display higher rates of obesity. This exploratory study investigated associations between consumption of snack foods, sugar-sweetened beverages (SSB) and overweight and obesity in children from low-income households. Design/methodology/approach Data from households that participated in a multi-state cost-offset (CO-CSA) community supported agriculture intervention in 2016 and 2017 (n = 305) were analyzed. Fixed effect regression models were used to estimate associations between child monthly consumption of salty snack foods; sweet snack foods and SSBs; and child weight status, accounting for demographic characteristics. Findings No associations were found between snack or SSB consumption and child overweight. However, household income was significantly, negatively related to all three consumption variables (Salty snacks: ß = −0.09, SE = 0.04, p = 0.02; Sweet snacks: ß= −0.10, SE = 0.04, p = 0.01; SSB: ß= −0.21, SE = 0.05, p = 0.0001). The results suggest that household income may play an important role in children’s snacking and SSB behaviors among more disadvantaged households. Practical implications Factors beyond snack food and SSB consumption should be explored to better understand childhood overweight and obesity, and to inform future obesity interventions. Originality/value Socioeconomic disparities in childhood obesity are an ongoing policy-relevant issue within the USA and internationally. This study provides new information about child snacking behaviors in a unique, low-income population and contributes to the evidence base regarding the role household context in shaping child consumption behaviors.
