Abstract
Objectives: To examine the association between total animal protein intake and protein derived from different dietary sources (meat, fish and shellfish, eggs, and milk products) with global and abdominal obesity among adults in Luxembourg.
Methods: The study population was derived from a national cross-sectional stratified sample of 1152 subjects aged 18-69 years, recruited between November 2007 and January 2009. Binary logistic regression analysis was used to assess the relationship between animal protein intake (as a percentage of total energy intake) with global obesity (body mass index ≥ 30kg/m2) and abdominal obesity (waist circumference ≥ 102cm for men and ≥ 88cm for women), after controlling for potential confounders.
Results: There was an independent positive association between total animal protein intake and both global (odd ratio=1.15, 95% CI: 1.09-1.22) and abdominal obesity (odd ratio=1.12, 95% CI: 1.07-1.18) after adjustment for age, gender, education, smoking, physical activity, and intakes of total fat, carbohydrate, fiber, and fruit and vegetables. Protein intakes from meat, fish and shellfish were positively associated with global and abdominal obesity with further adjustment for vegetal protein and other sources of animal-derived protein (all P<0.01). Protein derived from eggs or milk products was unrelated to global or abdominal obesity.
Conclusion: Our findings suggest that protein derived from animal sources, in particular from meat, fish and shellfish, may be associated with increased risk of both global and abdominal obesity among presumably healthy adults in Luxembourg. These findings suggest that lower animal protein intakes may be important for healthy body weight maintenance.
