Summary
Mexican American men with higher traditional dietary intake showed a reduced likelihood of gallbladder disease (GBD). This suggests diet patterns are linked to GBD risk, warranting further research into dietary patterns and health outcomes.
Area of Science:
- Nutritional Epidemiology
- Gastroenterology
- Public Health
Background:
- Dietary patterns and their association with gallbladder disease (GBD) have yielded inconsistent results in previous studies.
- Mexican Americans represent a population with unique dietary habits and a potential predisposition to certain health conditions.
Purpose of the Study:
- To investigate the relationship between distinct food intake patterns and the prevalence of gallbladder disease (GBD) in Mexican Americans.
- To identify specific dietary patterns associated with a lower or higher risk of GBD within this demographic.
Main Methods:
- A cross-sectional study utilizing data from 4641 Mexican Americans (aged 20-74) from the NHANES III (1988-94).
- Gallbladder disease (GBD) was diagnosed via ultrasound.
- Food intake patterns were identified using principal components analysis of food frequency questionnaire data.
- Prevalence odds ratios (POR) and 95% confidence intervals (CI) were calculated for GBD across quartiles of dietary pattern scores.
Main Results:
- Four dietary patterns were identified in women (vegetable, high calorie, traditional, fruit) and three in men (vegetable, high calorie, traditional).
- No significant associations between dietary patterns and GBD were found in women after age adjustment.
- Men in the third and fourth quartiles of the traditional intake pattern had approximately half the odds of GBD compared to those in the lowest quartile (POR=0.42-0.53).
Conclusions:
- Dietary intake patterns are potentially valuable indicators for understanding diet-disease associations, including gallbladder disease (GBD).
- The findings highlight a sex-specific association, with traditional diets in men potentially being protective against GBD.
- Further research and methodological validation are needed to refine the use of dietary patterns in assessing diet-disease relationships.
