The potential impact of animal protein intake on global and abdominal obesity: evidence from the Observation of Cardiovascular Risk Factors in Luxembourg (ORISCAV-LUX) study

Objective: To examine the association of total animal protein intake and protein
derived from different dietary sources (meat; fish and shellfish; eggs; milk
products) with global and abdominal obesity among adults in Luxembourg.
Design: Binary logistic regression analysis was used to assess the relationship
between animal protein intake (as a percentage of total energy intake) and global
obesity (BMI≥30·0 kg/m2) and abdominal obesity (waist circumference ≥102 cm
for men and ≥88 cm for women), after controlling for potential confounders.
Setting: Observation of Cardiovascular Risk Factors in Luxembourg (ORISCAVLUX)
study.
Subjects: The study population was derived from a national cross-sectional
stratified sample of 1152 individuals aged 18–69 years, recruited between
November 2007 and January 2009.
Results: There was an independent positive association between total animal
protein intake and both global (OR=1·18; 95 % CI 1·12, 1·25) and abdominal
obesity (OR=1·14; 95 % CI 1·08, 1·20) after adjustment for age, gender, education,
smoking, physical activity and intakes of total fat, carbohydrate, fibre, 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.
Conclusions: 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 maintenance of healthy body weight.
