Demographic and socio-economic shifts partly explain the Martinican nutrition transition: an analysis of 10-year health and dietary changes (2003-2013) using decomposition models

OBJECTIVE

The Caribbean has seen a dramatic shift in the obesity and chronic disease prevalence over the past decades, suggesting a nutrition transition. Simultaneously, Martinique has faced a demographic transition marked by significant population ageing. We aimed to differentiate the contribution of changes in health status and dietary intakes due to shifts in demographic and socio-economic characteristics (DSEC) from that due to unobserved factors.

DESIGN

Two cross-sectional surveys conducted in 2003 (n 743) and 2013 (n 573) on representative samples were used. Dietary intakes were estimated by 24-h recalls. The contribution of changes in health status and dietary intakes due to shifts in observed DSEC was differentiated from that due to unobserved factors over a 10-year interval, using Oaxaca-Blinder decomposition models.

SETTING

Martinique, French region in the Caribbean.

PARTICIPANTS

Martinican adults (≥16 years).

RESULTS

Over the study period, health status deteriorated, partly owing to shifts in DSEC, explaining 62 % of the change in the prevalence of hypertension (+13 percentage points (pp)) and 48 % of waist circumference change (+3 cm). Diet quality decreased (mean adequacy ratio -2pp and mean excess ratio + 2 pp) and energy supplied by ultra-processed food increased (+4 pp). Shifts in DSEC marginally explained some changes in dietary intakes (e.g. increased diet quality), while the changes that remained unexplained were of opposite sign, with decreased diet quality, lower fruits, tubers and fish intakes and higher energy provided by ultra-processed foods.

CONCLUSION

Explained dietary changes were of opposite sign to nutrition transition conceptual framework, probably because unobserved drivers are in play, such as food price trends or supermarkets spread.

Framing the Latin American nutrition transition in a historical perspective, 1850 to the present

This paper argues that many of the foundations and trends that led to the rise in obesity and other diet-related health problems in Latin America began to develop in the late nineteenth century. The tendency towards presentism in the nutrition transition literature provides a much abbreviated and limited history of changes in diet and weight. Whereas medical and nutrition researchers have tended to emphasize the recent onset of the crisis, a historical perspective suggests that increasingly global food sourcing prompted changes in foodways and a gradual "fattening" of Latin America. This paper also provides a methodological and historiographic exploration of how to historicize the nutrition transition, drawing on a diverse array of sources from pre-1980 to the present.

Caribbean nutrition transition: what can we learn from dietary patterns in the French West Indies?

PURPOSE

Despite the urgency regarding increasing rates of obesity and chronic diseases in the Caribbean, few studies described the nutrition transition. We aimed to provide such information by identifying dietary patterns in the French West Indies and their characteristics.

METHODS

This cross-sectional analysis included 1144 Guadeloupeans and Martinicans from a multistage sampling survey conducted on a representative sample. Dietary patterns were identified using principal component analysis followed by a clustering procedure, and described using multivariable regression models.

RESULTS

Four patterns were identified: (i) a "prudent" pattern characterized by high intakes of fruits, vegetables, legumes, seafood and yogurts, low intakes of fatty and sweet products, and a high Diet Quality Index-International (DQI-I); (ii) a "traditional" pattern characterized by high intakes of fruits, vegetables, tubers and fish, low intakes of red and processed meat, snacks, fast foods, and sweetened beverages, with a high DQI-I, mostly shaped by women and older persons; (iii) a "convenient" pattern characterized by high intakes of sweetened beverages, snacks, and fast foods, with the lowest DQI-I, principally shaped by young participants; (iv) a "transitioning" pattern characterized by high consumptions of bread, processed meat, sauces, alcoholic and sweetened beverages, but also high intakes of tubers, legumes, and fish, mainly shaped by men, middle aged, of whom 35% had metabolic syndrome.

CONCLUSION

The co-existing dietary patterns in the French West Indies, marked by a generational contrast, seem to reflect different steps in dietary change as described in the literature, suggesting an ongoing nutrition transition.

Comparison of baseline fat-related eating behaviors of Puerto Rican, Dominican, Colombian, and Guatemalan participants who joined a cholesterol education project

OBJECTIVE

The objective is to compare baseline fat-related eating behaviors among Hispanic subgroups who joined a cholesterol education research project in New England.

DESIGN

Participants attended baseline screenings as part of the study. They had their height, weight, and blood cholesterol measured and completed baseline surveys with demographic, risk factor, dietary, and psychosocial questions.

PARTICIPANTS

A total of 370 Puerto Rican, 210 Colombian, 357 Dominican, and 102 Guatemalan subjects participated in the baseline.

MAIN OUTCOME MEASURES

Dietary behavior was measured using the Food Habits Questionnaire (FHQ), which was originally developed to assess food choices and preparation patterns related to adopting a low-fat diet. Measures include FHQ fat summary scores (a reflection of total fat intake), fat behavior subscales, and individual fat-related behaviors.

ANALYSIS

Analysis of variance was used to compare FHQ fat summary scores and multivariate analysis of variance was used to compare fat behavior scores and individual food item scores for the 4 Hispanic subgroups. Age and gender were covariates in the models.

RESULTS

Puerto Rican participants had a significantly higher mean FHQ fat summary score than Dominicans and Guatemalans and a higher prevalence of many fat-related eating behaviors. Although there were some differences by subgroup, the 4 most prevalent fat-related behaviors were similar: cooking with fat/oil, eating higher-fat sweets, eating higher-fat snacks, and eating dinners with meat.

CONCLUSIONS AND IMPLICATIONS

Future educational programs and materials for diverse Hispanic audiences in the northeastern United States should include the above issues; however, educational materials and programs ought to be tailored to individuals whenever possible. Efforts may need to focus on Puerto Ricans, who had a higher prevalence of many fat-related behaviors in this study.

Trends in Body Mass Index in Developing Countries

The purpose of this study was to examine the extent to which adult body mass index (BMI) has changed in developing countries over the past several decades. The analysis is based on a compilation and analysis of mean BMI in 1,432 published samples from developing countries measured between 1957 and 1994. A hierarchical multiple-regression model is applied to these data, controlling for country and study as random covariates and modelling age, sex, socio-economic status, and year as fixed effects. The results reveal a statistically significant increase in mean BMI between 1957 and 1994 in all major regions of the developing world. The size of the increase was 1.4 kg/m2 over the 37-year period, with a 95% confidence interval of 0.4 to 2.4 kg/m2. Mean BMI appears to have increased in all major regions of the developing world, although the size of the increase varies across regions. Using assumptions about the statistical distribution of BMI within populations and cut-off points recommended by the World Health Organization, the analysis suggests that the increase in mean BMI may have resulted in a slight decrease in the prevalence of underweight (BMI<18.5 kg/m2) but is unlikely to have produced an increase in obesity (BMI>30 kg/m2) in most regions. By contrast, the use of lower cut-off points to define obesity, as is done in many individual studies, would suggest that obesity has increased in developing countries. These results highlight the importance of using standardized definitions for underweight and obesity among adults, the need to assess and consider the prevalence of both conditions simultaneously during planning and policy development, and the need to identify policy instruments appropriate to the nutritional profile within a country.

The obesity epidemic is a worldwide phenomenon

Obesity is not just a disease of developed nations. Obesity levels in some lower-income and transitional countries are as high as or higher than those reported for the United States and other developed countries, and those levels are increasing rapidly. Shifts in diet and activity are consistent with these changes, but little systematic work has been done to understand all the factors contributing to these high levels. The goal of this review is to provide an understanding of the patterns and trends of obesity around the world and some of the major forces affecting these trends. Several nationally representative and nationwide surveys are discussed.
