What factors should we focus on to prevent progression from healthy to unhealthy BMI in Australian women?

Brown, Wendy and Kabir, Enamul and Clark, Bronwyn and Gomersall, Sjaan (2016) What factors should we focus on to prevent progression from healthy to unhealthy BMI in Australian women? In: 6th International Congress on Physical Activity and Public Health (ISPAH 2016), 16-19 Nov 2016, Bangkok, Thailand.


Purpose: To assess the determinants of maintaining a healthy BMI over 16 years in women, from age 18-23 to 34-39 years.

Methods: 4881 women with healthy BMI at baseline, and either healthy, overweight or obese BMI at 16-year follow-up, reported weight, height, health and health behaviours in six surveys of the Australian Longitudinal Study on Women’s Health between 1996 and 2012. The roles of physical activity and other determinants of BMI maintenance and change were estimated using bivariate logistic regression and generalised estimating equations (GEE).

Results: Almost 60% remained in the healthy BMI category, 29% transitioned to overweight and 11.6% became obese. Mean rates of weight gain were 0.19kg/year , 0.84kg/year and 1.74kg/year respectively. In adjusted models, seven factors were associated with maintaining a healthy BMI (physical activity, alcohol, education [positive associations], smoking, high sitting time, energy intake, use of oral contraceptives [negative associations]).

Conclusions: Physical activity was protective against transition to overweight and obesity, but the results suggest that activity interventions for preventing weight gain should also include other determinants, including sitting time, alcohol, energy intake and smoking.
Innovation: Progression from healthy weight to overweight or obesity is associated with numerous health problems in young adult women. Rates of weight gain appear to be established in the early 20s, and are underpinned by seven factors. Early detection of high rates of weight gain and strategies to change multiple behaviours, including physical activity, might avert progression to overweight and obesity in young adult women.
