Dietary predictors of 5-year changes in waist circumference

BACKGROUND: Previous studies on the association between macronutrient intake and the development of abdominal obesity, which carries an increased health risk, have not shown a consistent pattern, possibly due to mixed effects of other aspects of the food intake.

OBJECTIVE: This study investigated the association between intake from 21 food and beverage groups and the subsequent 5-year difference in waist circumference.

METHODS: The study population consisted of 22,570 women and 20,126 men, aged 50 to 64 years at baseline, with complete data on baseline and follow-up waist circumference, baseline diet (192 items food frequency questionnaire), body mass index, and selected potential confounders (eg, smoking status, sport activities, and intake of alcoholic beverages). Multiple linear regression analyses were performed.

RESULTS: For women, 5-year difference in waist circumference was inversely related to intake from red meat, vegetables, fruit, butter, and high-fat dairy products, whereas intake from potatoes, processed meat, poultry, and snack foods was positively associated. For men, red meat and fruit intakes were inversely associated with 5-year difference in waist circumference, whereas snack foods intake was positively associated. Sex differences occurred for vegetables, high-fat dairy products, and processed meat.

CONCLUSIONS: The results suggest that a diet low in fruits and red meat and high in snack foods was associated with larger waist circumference gains in both sexes. Furthermore, in women a diet low in vegetables, butter, and high-fat dairy products, and high in poultry, potatoes, and processed meat were likely determinants of subsequent gain at the waist.

Hmmm...red meat, vegetables, fruit, butter, high fat dairy products...that sounds almost like paleo to me!

cept I think Paleo has a no dairy thing, or is it just the pasteurized stuff?

Prediction by scientists, that eating crap leads to crap, verified by empirical evidence.

News at 11.

I wonder what this means though: "Sex differences occurred for vegetables, high-fat dairy products, and processed meat.", or is it just this bit in the conclusion part: "Furthermore, in women a diet low in vegetables, butter, and high-fat dairy products, and high in poultry, potatoes, and processed meat were likely determinants of subsequent gain at the waist."

Interesting how they highlight the differences between red meat versus poultry.

How come they don't measure the caloric intake/output?

[galapogos]

Explain to me how you do that in an observational study?

[Weib]

baseline diet (192 items food frequency questionnaire) - estimates of portion size.

And you expect that to be accurate over tens of thousands of people over 5 years? Good luck!
