Lower subjective social status is associated with increased adiposity and self-reported eating in the absence of hunger due to negative affect among children reporting teasing distress.

OBJECTIVES: Low social standing and teasing are independently associated with increased body mass index (BMI) and overeating in children. However, children with low social status may be vulnerable to teasing. METHODS: We tested the statistical interaction of subjective social status (SSS) and subjective socioeconomic status (SSES) and teasing distress on BMI, fat mass index (FMI), and eating in the absence of hunger (EAH) in children (Mage = 13.09 years, SD = 2.50 years; 27.8% overweight/obese). Multiple linear regressions identified the main effects of self-reported SSS (compared to peers in school), distress due to teasing, and their interaction on BMI (n = 115), FMI (n = 114), and child- (n = 100) and parent-reported (n = 97) EAH. RESULTS: Teasing distress was associated with greater BMI, FMI, and child-reported EAH due to negative affect (a subscale of EAH) and total EAH scores. There were no associations of SSS with these outcomes. However, there was an interaction between SSS and teasing distress for BMI, FMI, and EAH from negative affect such that lower SSS was associated with higher BMI, FMI, and EAH from negative affect in the presence of teasing distress. However, there were no main effects or interactions (with teasing distress) of SSES on the outcomes. CONCLUSIONS: These findings suggest that the relationship between lower SSS and increased adiposity and overeating behaviors may be exacerbated by other threats to social standing, such as teasing. Children exposed to multiple social threats may be more susceptible to eating beyond physiological need and obesity than those who experience a single form of perceived social disadvantage.

Independent and Interactive Associations of Subjective and Objective Socioeconomic Status With Body Composition and Parent-Reported Hyperphagia Among Children.

Background: Subjective socioeconomic status (SSES) and objective socioeconomic status (OSES) have been independently associated with body composition and eating behavior in children. While low OSES may constrain access to healthier foods, low SSES has been associated with increased preference for and motivation to consume higher energy foods and portions independent of OSES. Despite these distinct ways that OSES and SSES may affect children's eating behavior and adiposity, their joint contributions remain unclear. We investigated the independent and interactive associations of SSES and OSES with children's BMI, fat mass index (FMI), and caregiver-reported hyperphagia. Methods: Data were derived from the Children's Growth and Behavior Study, an ongoing observational study. Multiple linear regressions used child's SSES and OSES of the family as independent factors and modeled the statistical interaction of SSES and OSES with BMI (n = 128), FMI (n = 122), and hyperphagia and its subscales (n = 76) as dependent variables. Results: SSES was independently and negatively associated with hyperphagia severity and OSES was independently and negatively associated with both FMI and hyperphagia severity. There was a statistical interaction effect of SSES and OSES on hyperphagia severity-lower SSES was associated with greater hyperphagia severity only at lower levels of OSES. Conclusions: These findings demonstrate a relationship between low OSES and child adiposity and that the relationship between child SSES and hyperphagia severity may be most relevant for children from households with lower family OSES. Future research on socioeconomic disparities in children's body composition and eating behaviors should examine the interaction of SSES and OSES. Clinical Trial Registration: NCT02390765.

Relationships between early-life family poverty and relative socioeconomic status with gestational diabetes, preeclampsia, and hypertensive disorders of pregnancy later in life.

PURPOSE: Low early-life absolute and relative socioeconomic status (SES) may contribute to socioeconomic disparities in pregnancy complications (i.e., gestational diabetes mellitus [GDM], preeclampsia/eclampsia [PE], hypertensive disorders of pregnancy [HDP; preeclampsia/eclampsia, gestational hypertension, chronic hypertension]), but their independent associations with pregnancy complications have not been studied. This study investigated associations of early-life poverty and relative SES with risks of GDM, PE, and HDP. METHODS: National Longitudinal Study of Adolescent to Adult Health data were used (GDM n = 802; PE n = 813; HDP n = 801). Objective poverty was defined as wave I low-income or receipt of federal nutrition assistance benefits. Relative SES was self-reported at wave V (ages 33-39) by asking whether the participant's family was financially worse off than average when growing up. Logistic regressions assessed relationships between poverty, relative SES, and self-reported lifetime diagnoses of GDM, PE, or HDP. RESULTS: Lifetime prevalences of GDM, PE, and HDP were 9.23%, 12.00%, and 21.93%, respectively. Low relative SES (odds ratio: 2.04 [1.07, 3.89]) and poverty (odds ratio: 1.81 [0.97, 3.38]) were independently associated with GDM but not with PE or HDP. CONCLUSIONS: Early-life poverty and relative SES are associated with GDM; understanding the mechanisms underlying these associations may help identify novel intervention targets to reduce socioeconomic disparities in GDM.
