Objective: The purpose of the study was to test the moderating influence of two risk factors, maternal depression and socio-economic status (SES), on the association between authoritarian and permissive parenting styles and child obesity. Design: Correlational, cross-sectional study. Parenting style was measured with the Parenting Styles and Dimensions Questionnaire (PSDQ). Maternal depression was measured using the Center for Epidemiologic Studies Depression Scale (CES-D). BMI-for-age percentile was used to categorize children by weight status (children with BMI-for-age $95th percentile were classified as obese). SES was computed from parent education and occupational status using the four-factor Hollingshead index. Setting: Rural public schools in a mid-western state in the USA. Subjects: One hundred and seventy-six mothers of first-grade children (ninety-one boys, eighty-five girls) enrolled in rural public schools. Results: Both maternal depression and SES were found to moderate the permissive parenting style/child obesity association, but not the authoritarian/child obesity association. For depressed mothers, but not for non-depressed mothers, more permissive parenting was predictive of child obesity. Similarly more permissive parenting was predictive of child obesity among higher SES mothers, but not for lower SES mothers. Conclusions: Maternal depression and SES interact with permissive parenting style to predict child obesity. Future research should examine the relationship among these variables using a longitudinal design.

More complex models than those currently available are needed to guide research about childhood obesity. This article presents an interpersonal and intrapersonal risk model of child obesity, a transdisciplinary model of psychosocial risk factors that is based on work in developmental, family, and nutritional sciences. Two interpersonal realms of child development identified as being potentially significant for understanding the development and maintenance of overweight include the child's family and peer contexts. Child intrapersonal variables proposed as mediators between these contexts and weight outcomes include poor self‐regulation and self‐awareness, negative affect, and emotional or external eating. The article encourages developmental scientists to add their expertise to the study of childhood obesity by using models such as the one outlined here for the generation and testing of hypotheses so that future intervention efforts may be improved.

The purpose of this study was to assess the nutritional status and cognitive performance of women and their 5-year-old children using a cross-sectional design. Cognitive performance of mothers and children was assessed with Raven's Colored Progressive Matrices (CPM) and Kaufman Assessment Battery for Children-II (KABC-II). Demographic characteristics, food consumption patterns and anthropometry were also measured. Four rural districts in Sidama, southern Ethiopia served as the setting for this study. Subjects were one hundred women and their 5-year-old children. Mean ± standard deviation age of the mothers was 29 ± 6 years and family size was 7.0 ± 2.6. Maternal body mass index (BMI) ranged from 15.3 to 29.0 with 14% of the mothers having BMI < 18.5. Anthropometric assessment of children revealed 29% to be stunted (height-for-age z-score < -2) and 12% to be underweight (weight-for-age z-score < -2). Mothers' education significantly contributed to prediction of both mothers' and children's cognitive test scores. There were significant differences in mean cognitive test scores between stunted and non-stunted, and between underweight and normal-weight children. Height-for-age z-scores were correlated with scores for short-term memory (r = 0.42, P < 0.001), and visual processing (r = 0.42, P < 0.001) indices and weight-for-age z-scores were also correlated with scores of short-term memory (r = 0.41, P < 0.001) and visual processing (r = 0.43, P < 0.001) indices. Malnutrition in the community likely contributed to the cognitive performance of the subjects. Performance on memory and visual processing tasks was significantly lower in children with growth deficits suggesting that efficient and cost effective methods to alleviate malnutrition and food insecurity would impact not only child health but also cognitive function.
