A study of dietary patterns in the Mexican-American population and their association with obesity

OBJECTIVE: Data from the National Health and Nutrition Examination Survey 2001-2002 indicate that prevalence of overweight and obesity continues to rise among Mexican Americans. Little is know about the dietary factors associated with this trend. Ethnic groups have different dietary patterns based on their geographical locations and cultural influences. We examined the dietary patterns of Mexican Americans and their association with total and central obesity. We hypothesized that Mexican-American adults following a traditional diet would have a lower prevalence of obesity than those following a more typical American diet. SUBJECTS: Data from the National Health and Nutrition Examination Survey 2001-2002 included 659 Mexican-American adults, ages 18 years and older. EXPERIMENTAL DESIGN: Dietary patterns were defined by cluster analysis of food group variables, expressed as percentage contribution to total energy intake. Obesity was assessed by body mass index (calculated as kg/m2) and central obesity by waist circumference. RESULTS: We defined four dietary patterns, each named for the food groups that were most predominant relative to the other clusters: poultry and alcohol, milk and baked products, traditional Mexican, and meat. Surprisingly, we did not identify a clear "healthy pattern" group in this population, as has been generally observed in other ethnic groups. Although the traditional Mexican diet contains relatively high intakes of legumes and dietary fiber, it also was high in cholesterol. Contrary to our hypothesis, those consuming the traditional Mexican diet pattern had high BMI and waist circumference values, which did not differ significantly from other groups. CONCLUSION: In this representative population of Mexican-American adults, we identified distinct dietary patterns, but these were not significantly associated with obesity. Rather, obesity was prevalent in all diet groups. More details on possible changes within the traditional pattern, including use of fast food vs home-prepared Mexican foods, are needed to better understand how diet can be associated with obesity in this population.     

Diet composition and risk of overweight and obesity in women living in the southwestern United States

OBJECTIVE: It is unknown whether dietary patterns or macronutrient composition contribute to the observed differences in rates of overweight and obesity among Hispanic and non-Hispanic white women in the United States. We assessed the association of dietary patterns and macronutrient composition with overweight and obesity in Hispanic and non-Hispanic white women. DESIGN: Cross-sectional analysis of dietary data from a case-control study of breast cancer. PARTICIPANTS: Population-based control participants (871 Hispanic and 1,599 non-Hispanic white women) from the southwestern United States who completed the diet and other components of the interview and whose anthropometric measurements were available. MAIN OUTCOME MEASURES: Body mass index (BMI; calculated as kg/m(2)), weight status (overweight, BMI 25 to 29.9; obese, BMI>30). STATISTICAL ANALYSES PERFORMED: Dietary patterns were defined using factor analysis. Associations of dietary patterns and macronutrient composition with overweight and obesity as compared with normal weight were assessed with logistic regression. RESULTS: Hispanic women reported consuming more energy, a greater proportion of energy from fat and vegetable protein, less alcohol, and less energy from animal protein compared with non-Hispanic white women. Western and dieter patterns were associated with higher prevalence of overweight and obesity; the Prudent dietary pattern was associated with a 29% lower prevalence of overweight and a halving of the prevalence of obesity similarly in Hispanic and non-Hispanic white women. Higher proportions of energy from protein (odds ratio [OR] 1.81, 95% confidence interval [CI] 1.28 to 2.56) and animal protein (OR 2.10 95% CI 1.47 to 2.98) were associated with a greater risk of overweight; greater proportions of energy from fat (OR 2.28, 95% CI 1.27 to 4.08), protein (3.55 95% CI 2.38 to 5.29), or animal protein (3.44 95% CI 2.31 to 5.14) were associated with higher risk of obesity among non-Hispanic white women only. CONCLUSIONS: A Western dietary pattern was associated with greater risk and a Prudent diet with reduced risk of overweight and obesity. To reduce risk of overweight and obesity, Hispanic women should maintain healthful aspects of a native Hispanic diet, and non-Hispanic white women should replace animal protein with vegetable protein.     

Food patterns measured by factor analysis and anthropometric changes in adults

BACKGROUND: Sixty-five percent of US adults are overweight, and 31% of these adults are obese. Obesity results from weight gains over time; however, dietary determinants of weight gain remain controversial. OBJECTIVE: Our objective was to examine whether food patterns derived from exploratory factor analysis are related to anthropometric changes. We hypothesized that we would derive a healthy food pattern and that it would predict smaller changes in body mass index (BMI; in kg/m(2)) and waist circumference (in cm) than would other food patterns in models adjusted for baseline anthropometric measures. DESIGN: The subjects were 459 healthy men and women participating in the Baltimore Longitudinal Study of Aging. Diet was assessed by using 7-d dietary records, from which 40 food groups were formed and entered into a factor analysis. RESULTS: Six food patterns were derived. Factor 1 (reduced-fat dairy products, fruit, and fiber) was most strongly associated with fiber (r = 0.39) and loaded heavily on reduced-fat dairy products, cereal, and fruit and loaded moderately on fruit juice, nonwhite bread, nuts and seeds, whole grains, and beans and legumes. In a multivariate-adjusted model in which the highest and lowest quintiles were compared, factor 1 was inversely associated with annual change in BMI (beta = -0.51; 95% CI: -0.82, -0.20; P < 0.05; P for trend < 0.01) in women and inversely associated with annual change in waist circumference (beta = -1.06 cm; 95% CI: -1.88, -0.24 cm; P < 0.05; P for trend = 0.04) in both sexes. CONCLUSION: Our results suggest that a pattern rich in reduced-fat dairy products and high-fiber foods may lead to smaller gains in BMI in women and smaller gains in waist circumference in both women and men.     

Dietary patterns and changes in body mass index and waist circumference in adults

BACKGROUND: Obesity has increased > 20% in the past decade in the United States, and more than one-half of US adults are overweight or obese. OBJECTIVE: Our objective was to further elucidate the nutritional etiology of changes in body mass index (BMI; in kg/m(2)) and waist circumference by dietary intake pattern. We hypothesized that a healthy dietary pattern would lead to smaller changes in BMI and waist circumference than would other dietary patterns. DESIGN: Subjects were 459 healthy men and women participating in the ongoing Baltimore Longitudinal Study of Aging. Diet was assessed with the use of 7-d dietary records, from which 41 food groups were created and entered into a cluster analysis. RESULTS: Five dietary patterns were derived (healthy, white bread, alcohol, sweets, and meat and potatoes). The mean annual change in BMI was 0.30 +/- 0.06 for subjects in the meat-and-potatoes cluster and 0.05 +/- 0.06 for those in the healthy cluster (P < 0.01). The mean annual change in waist circumference was more than 3 times as great for subjects in the white-bread cluster (1.32 +/- 0.29 cm) as for those in the healthy cluster (0.43 +/- 0.27 cm) (P < 0.05). CONCLUSIONS: Consuming a diet high in fruit, vegetables, reduced-fat dairy, and whole grains and low in red and processed meat, fast food, and soda was associated with smaller gains in BMI and waist circumference. Because foods are not consumed in isolation, dietary pattern research based on natural eating behavior may be useful in understanding dietary causes of obesity and in helping individuals trying to control their weight.     

Factors associated with dietary patterns in the urban Brazilian population

This study evaluated factors associated with dietary patterns in the Brazilian population based on the Living Standards Survey conducted in the Northeast and Southeast regions of the country. Multi-stage probability sampling was employed to select the households, and for the present analysis 5,121 adults aged 20 to 50 years were included. Pregnant women and individuals reporting chronic health conditions were excluded. Through principal component analysis, two major family dietary patterns were identified: a mixed pattern, in which all groups and foods have approximately the same factor loading, and a second pattern based main1y on rice and beans, which was called a traditional diet. Weight and height were measured in the households, and food intake was based on a 21-item semi-quantitative family questionnaire. The Northeast (as compared to the Southeast) was negatively associated with the mixed pattern. Body mass index was positively associated with the mixed pattern, whereas leisure physical activity and Black skin color were negatively associated with the mixed pattern. Schooling and income levels explained most of the dietary variance, but after adjusting for education and income, region of residence remained significantly associated and was the third most important explanatory variable.     

Longitudinal changes in food patterns predict changes in weight and body mass index and the effects are greatest in obese women

The prevalence of obesity is increasing in most parts of the world. The objective of this study was to examine whether changes in food patterns were associated with changes in BMI among women over 9 y. Data were from 33,840 women participating in the Swedish Mammography Cohort in 1987 and 1997. Diet was assessed with a FFQ at both time points and 4 food patterns were derived using confirmatory factor analysis (Healthy, Western/Swedish, Alcohol, and Sweets). Our exposure variables were defined as change in factor score for each food pattern from 1987 to 1997. Our outcome variable was defined as change in BMI during the same period, and we also examined change in weight. Normal weight and overweight women had positive changes in weight and BMI during follow-up, whereas obese women had negative changes in BMI and weight; we observed a significant interaction between change in food patterns and baseline BMI. Obese subjects who increased their factor score for the Healthy pattern had larger decreases in BMI (beta = -0.18 kg/m(2) for a 1 unit increase in SD score, CI: -0.26 to -0.10; P < 0.0001), whereas normal weight and overweight women who increased their Healthy pattern score had smaller increases in BMI (-0.05 kg/m(2) and -0.11 kg/m(2), respectively; P < 0.05 for both). Obese women who increased their Healthy pattern score >3 SD had almost a 4 kg decrease in weight and a 1 unit decrease in BMI at follow-up. In conclusion, changes in eating patterns were significantly related to changes in BMI over 9 y and the effect was modified by baseline BMI. Pattern analysis is helpful in generating hypotheses regarding the role of diet in obesity, and additional research is needed to understand which elements of our patterns are protective or risk factors for weight gain.     

Dietary patterns and mortality in Danish men and women: a prospective observational study

The analysis of dietary patterns emerged recently as a possible approach to examining diet-disease relation. We analysed the risk of all-cause and cardiovascular mortality associated with dietary patterns in men and women, while taking a number of potential confounding variables into account. Data were from a prospective cohort study with follow-up of total and cause-specific mortality. A random sample of 3698 men and 3618 women aged 30-70 years and living in Copenhagen County, Denmark, were followed from 1982 to 1998 (median 15 years). Three dietary patterns were identified from a twenty-eight item food frequency questionnaire, collected at baseline: (1) a predefined healthy food index, which reflected daily intakes of fruits, vegetables and wholemeal bread, (2) a prudent and (3) a Western dietary pattern derived by principal component analysis. The prudent pattern was positively associated with frequent intake of wholemeal bread, fruits and vegetables, whereas the Western was characterized by frequent intakes of meat products, potatoes, white bread, butter and lard. Among participants with complete information on all variables, 398 men and 231 women died during follow-up. The healthy food index was associated with reduced all-cause mortality in both men and women, but the relations were attenuated after adjustment for smoking, physical activity, educational level, BMI, and alcohol intake. The prudent pattern was inversely associated with all-cause and cardiovascular mortality after controlling for confounding variables. The Western pattern was not significantly associated with mortality. This study partly supports the assumption that overall dietary patterns can predict mortality, and that the dietary pattern associated with the lowest risk is the one which is in accordance with the current recommendations for a prudent diet.     

Diet and glucose tolerance in a Chinese population

BACKGROUND: Associations between dietary factors and glucose tolerance observed in Caucasian populations may not be applicable to Chinese populations, since the traditional Chinese diet contains plentiful vegetables and is rice-based (which has a lower glycemic index than potatoes). To address this question, the dietary patterns in 988 Hong Kong Chinese subjects with normal and impaired glucose tolerance, and diabetes, were examined in a cross sectional survey to determine if there is any association between diet and glucose tolerance. METHOD: A stratified random population sample of 988 subjects (488 male, 500 female) was recruited. A food frequency questionnaire was used to determine dietary intake, and glucose tolerance was examined using the glucose tolerance test and the WHO criteria used to classify subjects into the three glucose tolerance categories. RESULTS: Using the standardized world population of Segi, the prevalence rate for DM was 6.6% for men and 5.7% for women; and for IGT 10.3% for men and 15.4% for women aged 30-64 y. Abnormal glucose tolerance is associated with female gender, older age, lower educational attainment and higher body mass index (BMI). No clear pattern of association with dietary factors was observed after adjusting for confounding factors. However, if subjects with BMI>or=25 kg/m(2) were excluded, an increase in mean consumption of rice/noodles/pasta per week was observed in the DM group, after adjusting for total energy intake and other confounding factors. No association between dietary variety, which has been linked with body fatness, and glucose tolerance, was observed. CONCLUSION: Dietary habit may not be a strong risk factor for the development of glucose intolerance in Chinese populations, given the favorable features of the Chinese diet. The high consumption of rice in the DM subjects who are of normal BMI suggests that further studies examining glycemic indices of Chinese food items may be beneficial. Obesity still remains the most important predisposing factor.     

Diet and Leukocyte Telomere Length in a Population with Extended Longevity: The Costa Rican Longevity and Healthy Aging Study (CRELES)

Elderly Costa Ricans have lower mortality rates compared to their counterparts from developed countries. Reasons for this survival advantage are not completely known. In the present study, we aimed to identify dietary factors associated with leukocyte telomere length (LTL), a marker of biologic aging, in the elderly population of Costa Rica. We conducted prospective analysis in 909 participants aged 60+ years from the Costa Rican Longevity and Healthy Aging Study (CRELES). We used a food frequency questionnaire to assess usual diet. We calculated dietary patterns using Principal Component Analysis (PCA). We used generalized linear models to examine the association of dietary patterns and food groups with leukocyte telomere length. We found two major dietary patterns explaining 9.15% and 7.18% of the total variation of food intake, respectively. The first dietary pattern, which represents a traditional Costa Rican rice and beans pattern, was more frequent in rural parts of the country and was positively associated with baseline LTL: β (95% CI) = 42.0 base-pairs (bp) (9.9 bp, 74.1 bp) per one-unit increase of the traditional dietary pattern. In analysis of individual food groups, intake of grains was positively associated with baseline LTL: β (95% CI) = 43.6 bp (13.9 bp, 73.3 bp) per one-serving/day increase of consumption of grains. Our results suggest that dietary factors, in particular a traditional food pattern, are associated with telomere length and may contribute to the extended longevity of elderly Costa Ricans.     

Dietary patterns associated with functional constipation among Japanese women aged 18 to 20 years: a cross-sectional study

Although several nutrients and foods have been suggested to be preventive for constipation, all previous studies have examined a single nutrient or food in each analysis. In contrast, analysis of dietary patterns may provide new insights into the influence of diet on functional constipation. We conducted a cross-sectional examination of the association between dietary pattern and functional constipation in 3,770 Japanese female dietetic course students aged 18-20 y from 53 institutions in Japan. Diet was assessed with a validated self-administered diet history questionnaire with 148 food items, from which 30 food groups were created and entered into a factor analysis. Functional constipation was defined using the Rome I criteria, which has previously been used in several epidemiologic studies on constipation. The prevalence of functional constipation was 26.0% (n=979). Four dietary patterns were identified: (1) "Healthy", (2) "Japanese traditional", (3) "Western," and 4) "Coffee and dairy products." After adjustment for several confounding factors, the "Japanese traditional" pattern, characterized by a high intake of rice, miso soup, and soy products and a low intake of bread and confectionaries, was associated with a significantly lower prevalence of functional constipation. In comparison with the lowest quintile, the multivariate adjusted odds ratio (95% confidence interval) was 0.52 (0.41-0.66) in the highest quintile (p for trend < 0.0001). Other dietary patterns were not associated with functional constipation. The Japanese traditional dietary pattern, characterized by a high intake of rice and a low intake of bread and confectionaries, may be beneficial in preventing functional constipation in young Japanese women.     

Dietary Patterns and Obesity in Chinese Adults: A Systematic Review and Meta-Analysis

Certain dietary patterns are associated with an increased risk of obesity and its comorbidities. However, these associations vary across populations. The prevalence of obesity has been rising amid a drastic nutrition transition in China during the country’s rapid economic growth. This systematic review and meta-analysis were conducted to summarize how dietary patterns are associated with obesity in the Chinese population. We searched for articles from 1 January 2000 to 1 February 2022 in PubMed, Cumulative Index to Nursing and Allied Health Literature (CINAHL), and Scopus that assessed the relationship between dietary patterns and obesity outcomes. Odds ratios (ORs) and 95% confidence intervals (CIs) were estimated using a random effects model. From the 2556 articles identified from the search, 23 articles were included in the analysis. We found that the traditional Chinese dietary pattern was associated with a lower risk of overweight/obesity (OR = 0.69, 95% CI: 0.57, 0.84, p < 0.001), whereas the Western dietary pattern was associated with a higher OR of overweight/obesity, but not reaching statistical significance (OR = 1.34, 95% CI: 0.98, 1.84, p = 0.07). There were inconsistent results for other dietary patterns, such as meat/animal protein and plant/vegetarian patterns. In conclusion, the traditional Chinese diet characterized by vegetables, rice, and meat was associated with a lower risk of obesity. The heterogeneity in characterizing dietary patterns contributes to the inconsistency of how dietary patterns are associated with obesity in the Chinese population.     

Empirically derived major dietary patterns and their associations with overweight in Korean preschool children

Prevailing dietary patterns and their association with nutritional outcomes are poorly understood, particularly for children in Korea. Our purposes were to identify major dietary patterns and to examine their associations with overweight among young children in Korea. For 1441 preschool children, usual diet was assessed by a FFQ, from which thirty-three food groups were created and entered into a factor analysis. We identified three dietary patterns by relative intake frequency of (1) vegetables, seaweeds, beans, fruits, milk and dairy products (Korean healthy pattern); (2) beef, pork, poultry, fish and fast foods (animal foods pattern); and (3) ice cream, soda, chocolate, cookies and candies (sweets pattern). The Korean healthy pattern was associated with better health status. As compared with the lowest quintile, the multivariate-adjusted OR of the highest quintile for health status inferior or similar to their peers was 0.59 (95 % CI 0.42, 0.84). Likelihood of being overweight was higher among those in the highest quintile (OR 1.77 (95 % CI 1.06, 2.94)) v. the lowest quintile regarding the animal foods pattern. These findings suggest that major dietary patterns are predictors of overweight and health status in Korean preschool children.     

Gender,age, socio-demographic and lifestyle factors associated with major dietary patterns in the Spanish Project SUN (Seguimiento Universidad de Navarra)

OBJECTIVE: To ascertain the major dietary patterns in the cohort 'SUN' and to assess the association of several sociodemographic (including age and gender) and lifestyle variables with the adherence to these dietary patterns. DESIGN: This study is a cross-sectional analysis of 3847 subjects (1587 men and 2260 women) belonging to a prospective cohort study based on self-reported questionnaires. A factor analysis based on 30 predefined food groups was conducted to ascertain the major dietary patterns in the cohort. Multiple regression models were fitted to assess the relationship between several sociodemographic and lifestyle variables and the adherence to these dietary patterns (measured using two scores with observed values ranging from -3.2 to +4.6 for the Western pattern and -3.1 to +5.5 for the Mediterranean pattern). RESULTS: Two major dietary patterns were found. The first pattern was labelled as a 'Western' dietary pattern and the other as a 'Spanish-Mediterranean' dietary pattern. Younger subjects were more likely to follow a 'Western' dietary pattern; the coefficient representing the change for every 10 y increase in age was b=-0.24 (P<0.001) for men and b=-0.12 (P<0.001) for women. More physically active subjects were less likely to follow a 'Western' dietary pattern and more likely to follow a 'Spanish-Mediterranean' dietary pattern. CONCLUSIONS: An association between a higher level of physical activity during leisure time and adherence to a 'Spanish-Mediterranean' diet was apparent. However, the profile of being a young, sedentary and single male was identified as the most likely to exhibit a departure from the traditional 'Spanish-Mediterranean' diet and follow a 'Western' dietary pattern.

Case-control study of dietary patterns and endometrial cancer risk

Dietary patterns, rather than intakes of specific foods or nutrients, may influence risk of endometrial cancer (EC). This population-based case-control study in Canada (2002-2006) included incident EC cases (n = 506) from the Alberta Cancer Registry and controls frequency age-matched to cases (n = 981). Past-year dietary patterns were defined using factor analysis of food frequency questionnaire data. Logistic regression was used to estimate EC risk within quartiles of dietary patterns. Three patterns (sweets, meat, plants) explained 23% of the variance in the dietary data. In multivariable models, EC risk was significantly reduced by 30% for women in the highest quartile of the healthier plants pattern (OR = 0.70, 95% CI 0.50-0.98, P trend = 0.02). When stratified by body mass index (BMI; kg/m(2)), risk was further reduced among overweight or obese women with a BMI ≥25 (OR = 0.57, 95% CI 0.39-0.83; P trend = 0.004). EC was not associated with the less healthy sweets and meat patterns. However, risk was modestly, but not significantly, elevated for higher intakes of the meat pattern among overweight or obese women. A mostly plant-based dietary pattern may reduce EC risk. Recommendations for risk reduction should focus on maintaining a healthy weight and the role of diet should be studied further.     

Food and nutrient intakes and their associations with lower BMI in middle-aged US adults: the International Study of Macro-/Micronutrients and Blood Pressure (INTERMAP)

BACKGROUND: Clinical trial data show that reduction in total energy intake enhances weight loss regardless of the macronutrient composition of the diet. Few studies have documented dietary patterns or nutrient intakes that favor leanness [BMI (in kg/m(2)) ≤25] in free-living populations. OBJECTIVE: This investigation examined associations of usual energy, food, and nutrient intakes with BMI among US participants of the International Study of Macro-/Micronutrients and Blood Pressure (INTERMAP). DESIGN: The INTERMAP is an international cross-sectional study of dietary factors and blood pressure in men and women (ages 40-59 y) that includes 8 US population samples. The present study included data from 1794 Americans who were not consuming a special diet and who provided four 24-h dietary recalls and 2 timed 24-h urine collections. Multivariable linear regression with the residual method was used to adjust for energy intake; sex-specific associations were assessed for dietary intakes and urinary excretions with BMI adjusted for potential confounders including physical activity. RESULTS: Lower energy intake was associated with lower BMI in both sexes. Univariately, higher intakes of fresh fruit, pasta, and rice and lower intakes of meat were associated with lower BMI; these associations were attenuated in multivariable analyses. Lower urinary sodium and intakes of total and animal protein, dietary cholesterol, saturated fats, and heme iron and higher urinary potassium and intakes of carbohydrates, dietary fiber, and magnesium were associated with lower BMI in both sexes. CONCLUSION: The consumption of foods higher in nutrient-dense carbohydrate and lower in animal protein and saturated fat is associated with lower total energy intakes, more favorable micronutrient intakes, and lower BMI.     

Food intake patterns and risk of coronary heart disease: a prospective cohort study examining the use of traditional scoring techniques

OBJECTIVE: This study analyses the risk of coronary heart disease (CHD) associated with food intake patterns. DESIGN: A cohort study with follow-up in 1996 for first admission to hospital for a CHD diagnosis or death caused by CHD (280 cases). Three food patterns were identified from a food frequency questionnaire: (1) a predefined healthy food index; (2) a prudent diet (reflecting frequent intakes of wholemeal cereals, fruit and vegetables); and (3) a Western food pattern (reflecting frequent intakes of meat products, butter and white bread) derived by factor analysis. Both factor scores had a mean of zero and a standard deviation of 1. SETTING: Copenhagen County, Denmark. SUBJECTS: A random sample of 7316 adults participated in health examinations conducted either in 1982-1984, 1987, or 1991-1992. RESULTS: The healthy food index and the Western pattern were not associated with CHD. The prudent pattern was associated with a decreased risk of CHD (Hazard ratio (HR per score unit increase)=0.85; 95% confidence intervals (CI), 0.75, 0.96), but the association vanished (HR=1.06; 95% CI, 0.93, 1.21) after controlling for confounding. Body mass index (BMI) modified the effect of the prudent and the Western patterns on CHD risk, suggesting an inverse association between both patterns and CHD in persons with low BMI, while the risk of CHD seemed to be positively related to the prudent and the Western pattern in those with high BMIs. CONCLUSIONS: This study showed no association between dietary patterns and CHD risk, but suggests that BMI modifies the relation between diet and CHD risk.

Dietary patterns of Hispanic elders are associated with acculturation and obesity

The association of dietary patterns and obesity, particularly in Hispanics, is relatively poorly understood. This large U.S. population subgroup has a high prevalence of obesity and associated chronic conditions, and Hispanics are changing their dietary practices as they acculturate. Our objectives were 1) to identify dietary patterns among elderly Hispanics in Massachusetts, compared with those of non-Hispanic whites; 2) to associate dietary patterns with acculturation; and 3) to associate dietary patterns with total and central obesity. We used a representative sample of 449 Puerto Rican and 133 Dominican elders and a neighborhood-based sample of 243 non-Hispanic white elders, aged 60 to 92 y, from the cross-sectional Massachusetts Hispanic Elders Study. Obesity and central obesity were assessed with BMI (kg/m2) and waist circumference measurement, respectively. Acculturation was assessed by evaluating language use. Usual diet was assessed with a food frequency questionnaire specifically designed for use with this population. Dietary patterns were defined by cluster analysis of food group variables. We identified five clusters of individuals by dietary pattern, with proportionately greater energy intake from 1) fruit and breakfast cereal, 2) starchy vegetables, 3) rice, 4) whole milk and 5) sweets, respectively. Hispanics were less likely to follow the fruit and cereal or sweets patterns, and more likely to follow the starchy vegetables or milk patterns, than were non-Hispanic whites. Only Hispanics followed the rice pattern. Among Hispanics, acculturation was positively associated with the fruit and cereal pattern, and negatively with the rice pattern. Total and central obesity were positively associated with the rice pattern. Longitudinal studies are needed to clarify the causal nature of these associations.
