The Women's Health Trial Feasibility Study in Minority Populations: changes in dietary intakes

Article Abstract:

The Women's Health Trial Feasibility Study in Minority Populations (FSMP), a randomized clinical trial, has been used to evaluate feasibility of low-fat dietary interventions among postmenopausal women of varied ethnic backgrounds. Women aged 50-79 from minority populations, 16% of them Hispanic and 28% black, enrolled at certain clinics were studied. The 2,208 women met periodically with a nutritionist to make various diet changes including cutting down on fat intake, getting it to 20% of energy. Black and non-Hispanic white women had similar levels of fat reduction, but for Hispanic women the decrease was less. White bias in self-reported intakes may have given somewhat greater changes in fat intake than was justified. Results were similar to the about 10% of energy decrease seen in most trials. Large changes in fat consumption can be achieved in diverse study populations.

Assessment of trans-fatty acid intake with a food frequency questionnaire and validation with adipose tissue levels of trans-fatty acids

Article Abstract:

Researchers conducted a study to estimate trans-fatty acid intake using data from the US Department of Agriculture. They used a self-administered food frequency questionnaire. The study included 27 women and 24 men aged between 51 and 78 years. The average consumption of total trans-fatty acids was 2.24 g per day and 5% of total dietary fat. The concentration in buttock adipose tissue was 4.7% of total fatty acids.

Validity of methods used to assess vitamin and mineral supplement use

Article Abstract:

A validation study was conducted in 1996 to compare supplement data collected by telephone interviews and self-administered questionnaire. The correlation coefficient from the comparison of average daily supplemental vitamin and mineral intake was about 0.5. The results revealed that commonly used epidemiologic methods of assessing supplement use may incorporate a large amount of error in estimation of nutrients.
