Self-Efficacy Moderates the Relation Between Declines in Physical Activity and Perceived Social Support in High School Girls

AbstractObjectivesSome factors in infancy can play a role in the development of adolescent obesity. Understanding these factors can help prevent early complications in adolescents associated with obesity in adulthood. The aim of this study was to determine the prevalence of overweight and obesity among high school girls in Khorramabad and its relationship with breastfeeding history.MethodsThis was a cross-sectional study. This study was conducted in 832 high school girls during the academic year 2016–2017. Samples were selected by multi-stage random sampling. General questionnaires, physical activity, and 24-h food questions were completed through interviews with students. Data regarding breastfeeding was obtained by mothers.ResultsThe prevalence of overweight and obesity in the study population was 16.3 and 5.8%, respectively. Overweight and obesity had a significant association with breastfeeding history (p = 0.001), while there was no significant relationship between overweight and obesity with school type, student’s age, parental occupation, education Parents, household size, birth rate, physical activity, and energy intake.ConclusionsThe results of this study showed that breast feeding has a protective effect on overweight and obesity during adolescence. To reduce the incidence of overweight and obesity, necessary education regarding breastfeeding should be provided.

Abstract BackgroundUnderstanding motivational determinants of physical activity (PA) is essential to guide the implementation of PA at individual and population level. Knowledge about the cross-cultural generalizability of these determinants is lacking and they have mostly been studied as separate factors. This study compares a motivational process model across samples from diverse populations with, or at risk of diabetes. MethodsMeasurement invariance of barrier identified regulation, barrier self-efficacy and social support was assessed in a rural Ugandan sample (n=712) and disadvantaged samples with high proportions of immigrants in urban South Africa (n=566) and Sweden (n=147). These motivational determinants were then compared through multigroup structural equation modeling.ResultsThe studied motivational constructs showed scalar invariance. Latent mean levels of perceived social support and barrier self-efficacy were lower in South Africa and Sweden. Structural models (for different PA outcomes) were not consistent across settings except for the association between perceived social support and identified regulation. Identified regulation was only associated with vigorous PA in Uganda and with moderate PA in South Africa. The association between social support and PA outcomes ranged from weak to not significant and the association between self-efficacy and PA was not significant. Self-reported PA was highest in Uganda and lowest in Sweden. Self-reported vigorous PA was significantly related to lower hemoglobin A1c levels, while moderate PA was not.ConclusionsFindings suggest that: 1) it is feasible to compare a motivational process model across diverse settings; 2) there is lower perceived social support and self-efficacy in the urban, migrant samples; 3) identified regulation is a more promising determinant of PA than self-efficacy or social support in these populations; 4) associations between motivational determinants and PA depend on the perceived type and/or intensity of PA; 5) perceived relatedness functions as a basic psychological need across diverse settings; and 6) people’s perception of the PA they perform depends on their perceived level of intensity of PA which would have major implications for health promotion.
