The effect of social class on mid-age women's weight control practices and weight gain
Williams L et al. – The study provides longitudinal evidence from a nationally representative sample of women that social class is related to weight gain, and to certain weight control practices.Methods
- 11,589 mid–aged women (aged 47–52)
- Australian Longitudinal Study on Women's Health (ALSWH)
- Multivariate model tested whether mean weight change over a two–year period differed by social class after adjusting for area of residence, age, education, baseline BMI, and smoking.
- Working–class women gained significantly more weight at 1.27 (0.07) kg (95% CI: 1.12–1.42) over 2 years, compared with middle/upper–class women at 1.01 (0.07) kg (95% CI: 0.88–1.15).
- They were significantly more likely to use potentially harmful weight control practices than middle/upper–class women (8.9%) (Chi–squared test = 30.65, p < 0.0001), and less likely to meet physical activity recommendations.
