Abstract
  • The purpose of this study is to determine whether a 12-week nutrition and physical activity (PA) intervention program for middle-aged, pre-menopausal women at risk for Metabolic Syndrome (MetS) would reduce their risk factors. Ten overweight women (mean ± SD: age = 47 ± 3y; Body Mass Index = 31.0 ± 3.1 kg/m²) at risk for MetS were recruited and completed all phases of the program. At pre- and post-intervention participants completed 4-day weighted food records and PA logs. The intervention was focused on increasing whole grains, fruits and vegetables (servings/day), reducing saturated fat (g/day) and increasing PA (minutes/day). Participants significant increase in whole grains (Δ = 2.6 servings/day, p = 0.005), fiber (Δ = 6.9 g/day, p < 0.03) and PA (Δ = 39 minutes/day, p < 0.0001, n = 9), while significantly decreasing saturated fat intake (Δ = 7.5 g/day, P = 0.02). Fruit, vegetable and total fat intake did not change significantly. Body weight (kg) and % body fat did not change. The program was successful by fostering positive lifestyle behaviors known to reduce risk of MetS such as increased PA and improving some dietary factors. A larger sample size may be needed to see greater improvements in whole fruit, vegetable and total fat intake in a 12-week period.
