Physical activity and nutrition interventions: conceptualization and design essay

Advanced Search Abstract Evidence for effectiveness of school-based studies for prevention of adolescent obesity is equivocal. Tailoring interventions to specific settings is considered necessary for effectiveness and sustainability.

Physical activity and nutrition interventions: conceptualization and design essay

Advanced Search Abstract Low-income, multi-ethnic women are at elevated risk for obesity and chronic diseases, yet influences at different levels may act as barriers to changing risk behaviors. Following the birth of a child, childrearing and social isolation can exacerbate these influences.

The social ecological framework integrates behavior-change strategies at different levels, providing a strong theoretical base for developing interventions in this high-risk population.

The primary purpose of this randomized controlled trial is to test the efficacy of an educational model delivered by community-based paraprofessionals in improving diet, activity and weight loss among new mothers over a month postpartum period and a 6-month maintenance period.

This model fosters institutional change to support behavior changes influenced at intrapersonal and interpersonal levels, through collaboration with federal programs for low-income families: Participants are randomized to the Usual Care, e. If shown to be efficacious, this program will be readily sustainable through existing federal agencies.

An imbalance between dietary intake and energy expenditure can result in obesity, further contributing to incidence of chronic disease Visscher and Seidell, Disparities in diet and activity behaviors and their outcomes underscore the need for effective interventions in low-income, multi-ethnic groups USDHHS, ; Flegal et al.


Prospective studies have shown dramatic reductions in chronic disease risk with adherence to a low-risk health behavior profile Stampfer et al.

Addressing risk behaviors in concert can maximize the efficacy of interventions, because change in one behavior can serve as a gateway for change in others Marcus et al.

The postpartum period represents a time for establishing a behavioral pattern contributing to long-term risk of chronic disease among women. Childrearing demands coupled with fatigue, depression, multiple physical symptoms and social isolation McCormick et al. Obesity prevalence rises with age and with the number of pregnancies Brown et al.

This constellation of risks also supports conceptualization of the postpartum period as a window of opportunity to modify health practices Stover and Marnejon, Efficacy of behavior-change interventions will depend, however, on addressing multiple influences in the social context of low-income, multi-ethnic women that may constrain diet and physical activity behaviors Crockett et al.

Purpose A social ecological framework integrating theories of behavior change at different levels of influence is well suited to address systematically determinants of dietary intake and physical activity patterns in population groups at greatest risk of chronic disease. The primary purpose is to evaluate whether the Enhanced EFNEP model produces greater change in dietary intake, physical activity and pregnancy-related weight changes in the first 12 months postpartum and after 6 months of maintenance, compared with WIC care alone.

Community-based federal programs provide important channels for reaching low-income, multi-ethnic women. By collaborating with USDA programs already providing nutrition education to low-income families, we foster institutional change to maximize behavioral influences at individual and interpersonal levels.

Theoretical approach Within a social ecological framework McLeroy et al. This project will not directly alter community influences, e.Design and implementation of theory-based behavioral nutrition and physical activity interventions Methodological considerations in the design and evaluation of interventions For the Point Mar case study, to approach and help alleviate the onset of type II Diabetes in obese children, I will apply evidence-based and appropriate health education strategies/ methodologies surrounding the implementation of a Coordinated School Health › Home › Free essays › Health essays.
