Socioeconomic inequalities in metabolic syndrome in the French West Indies

Social determinants of health and metabolic syndrome in Colombian older adults

BACKGROUND AND AIMS

Social determinants of health (SDH) are critical in health outcomes. More insight is needed on the correlation between SDH and metabolic syndrome (MetS) in the aging population. This study assessed the association between SDH and MetS scores among older adults in Colombia.

METHODS AND RESULTS

This cross-sectional country-wide study includes a sample of 4085 adults aged ≥60 from the SABE Colombia Survey. MetS measurements were central obesity, hyperglycemia or diabetes, hypertriglyceridemia, arterial hypertension, and low HDL cholesterol (MetS score 0-5). SDH includes four levels: 1- general socioeconomic and environmental conditions; 2-social and community networks; 3- individual lifestyle; and 4-constitutional factors. In multivariate linear regression analysis, the SDH factors with greater effect sizes, calculated by Eta Squared, predicting higher MetS mean scores were women followed by low education, no alcohol intake, urban origin, and residing in unsafe neighborhoods. Two interactions: men, but not women, have lower MetS in safe neighborhoods compared to unsafe, and men, but not women, have lower MetS when having low education (0-5 years) compared to high (≥6).

CONCLUSION

Gender, education, alcohol intake, and origin have the greatest effect sizes on MetS. Education level and neighborhood safety modified the relationship between gender and MetS. Low-educated men or those residing in safe neighborhoods have lower MetS. Neighborhood environments and educational differences influencing MetS should be considered in future studies.

2024 Heart Disease and Stroke Statistics: A Report of US and Global Data From the American Heart Association

BACKGROUND

The American Heart Association (AHA), in conjunction with the National Institutes of Health, annually reports the most up-to-date statistics related to heart disease, stroke, and cardiovascular risk factors, including core health behaviors (smoking, physical activity, nutrition, sleep, and obesity) and health factors (cholesterol, blood pressure, glucose control, and metabolic syndrome) that contribute to cardiovascular health. The AHA Heart Disease and Stroke Statistical Update presents the latest data on a range of major clinical heart and circulatory disease conditions (including stroke, brain health, complications of pregnancy, kidney disease, congenital heart disease, rhythm disorders, sudden cardiac arrest, subclinical atherosclerosis, coronary heart disease, cardiomyopathy, heart failure, valvular disease, venous thromboembolism, and peripheral artery disease) and the associated outcomes (including quality of care, procedures, and economic costs).

METHODS

The AHA, through its Epidemiology and Prevention Statistics Committee, continuously monitors and evaluates sources of data on heart disease and stroke in the United States and globally to provide the most current information available in the annual Statistical Update with review of published literature through the year before writing. The 2024 AHA Statistical Update is the product of a full year's worth of effort in 2023 by dedicated volunteer clinicians and scientists, committed government professionals, and AHA staff members. The AHA strives to further understand and help heal health problems inflicted by structural racism, a public health crisis that can significantly damage physical and mental health and perpetuate disparities in access to health care, education, income, housing, and several other factors vital to healthy lives. This year's edition includes additional global data, as well as data on the monitoring and benefits of cardiovascular health in the population, with an enhanced focus on health equity across several key domains.

RESULTS

Each of the chapters in the Statistical Update focuses on a different topic related to heart disease and stroke statistics.

CONCLUSIONS

The Statistical Update represents a critical resource for the lay public, policymakers, media professionals, clinicians, health care administrators, researchers, health advocates, and others seeking the best available data on these factors and conditions.

Prevalence of metabolic syndrome in East Azerbaijan-Iran and its determinants factors

Introduction

Metabolic syndrome (MetS) is a prevalent metabolic disorder with increasing prevalence attributed to extended life expectancy. This study aims to investigate MetS prevalence and its determinants in the East-Azerbaijan population.

Methods

Conducted as a cross-sectional study within the East Azerbaijan region, this research is based on a major Lifestyle Promotion Project. The study encompasses 700 participants aged 15 to 65 years, representing the general population and selected using probability proportional to size multistage stratified cluster sampling. MetS diagnoses were conducted using the adult Panel III criteria. Data on socio-demographics, smoking status, and physical activity levels were collected through questionnaires.

Results

Among participants, the mean age was 42.4±12.38 years, and the mean body mass index was 27.69±4.94 kg/m2. The MetS group exhibited higher mean age and body mass index compared to the non-MetS group (P<0.001). The prevalence of MetS in the population was 34.2%, with higher rates in females (37.1%) compared to males (30.5%), though this difference wasn't statistically significant (P=0.11). Notably, a substantial distinction was observed between the two groups regarding education levels (P<0.001).

Conclusion

The study reveals a significant association between increasing age and higher prevalence of MetS. Furthermore, lower educational levels were linked to an elevated prevalence of MetS. While other socio-demographic factors didn't demonstrate statistically significant relationships, these findings emphasize the importance of targeted interventions and education in mitigating MetS risks.

Socioeconomic inequalities in metabolic syndrome and its components in a sample of Iranian Kurdish adults

OBJECTIVES

The worldwide incidence of metabolic syndrome (MetS) has increased in recent decades. In this study, we investigated the socioeconomic inequalities associated with MetS and its components in a sample of the Iranian Kurdish population.

METHODS

We used data from 3,996 participants, aged 35 years to 70 years, from the baseline phase of the Dehgolan Prospective Cohort Study (February 2018 to March 2019). The concentration index and concentration curve were used to measure inequality and the Blinder-Oaxaca decomposition method was used to examine the contribution of various determinants to the observed socioeconomic inequality in MetS and its components.

RESULTS

The prevalence of MetS was 34.44% (95% confidence interval [CI], 32.97 to 35.93). The prevalence of MetS was 26.18% for those in the highest socioeconomic status (SES), compared with 40.51% for participants in the lowest SES. There was a significant negative concentration index for MetS (C=-0.13; 95% CI, -0.16 to -0.09), indicating a concentration of MetS among participants with a lower SES. The most prevalent component was abdominal obesity (59.14%) with a significant negative concentration index (C=-0.21; 95% CI, -0.25 to -0.18). According to decomposition analysis, age, gender, and education were the highest contributing factors to inequality in MetS and its components.

CONCLUSIONS

This study showed socioeconomic inequality in MetS. People with a low SES were more likely to have MetS. Therefore, policymakers and health managers need to develop appropriate strategies to reduce these inequalities in MetS across age groups, genders, and education levels, especially among women and the elderly.

Quality of diet and odds of metabolic syndrome in Iranian adults: Baseline results from the PERSIAN Kavar cohort study (PKCS)

BACKGROUND AND AIMS

Metabolic Syndrome (MetS) is a major risk factor for cardiovascular diseases and type 2 diabetes mellitus. Diet quality has been associated with multiple chronic diseases. We aimed to investigate the association between the quality of diet and the odds of being diagnosed with MetS.

METHODS AND RESULTS

This study was conducted cross-sectionally on baseline data of 2225 individuals from the PERSIAN Kavar Cohort Study (PKCS). The quality of diet was measured based on the Diet Quality Index - International (DQI-I), using Food Frequency Questionnaires. The association between DQI-I and MetS and its components was measured via logistic regression models in crude and adjusted models. We did not observe any association between DQI-I and MetS in the overall population. However, after adjustment for potential confounders, we found that male participants with higher DQI-I scores had a lower risk of MetS [adjusted odds ratio (OR) 95% confidence interval CI) = 0.62 (0.42-0.93)]. Moreover, analogous trends were observed with respect to some components of MetS, including elevated triglyceride (TG) [crude OR (95% CI) = 0.89 (0.70-0.98); adjusted OR = 0.82 (0.65-0.93)], lowered high-density lipoprotein cholesterol (HDL-c) [crude OR (95% CI) = 0.79 (0.57-0.99); adjusted OR = 0.76 (0.55-0.97)], and abnormal glucose homeostasis [crude OR (95% CI) = 0.80 (0.55-0.94); adjusted OR = 0.73 (0.51-0.91)] only in male participants, both before and after adjustment for potential confounders.

CONCLUSION

In this study, we showed that higher adherence to a high-quality diet was associated with a lower chance of developing MetS in men. Biological gender might be responsible for the observed discrepancies.

Shifts in dietary patterns and risk of type-2 diabetes in a Caribbean adult population: ways to address diabetes burden

PURPOSE

As the French West Indies are facing an ongoing nutrition transition with increasing type-2 diabetes mellitus (T2DM) prevalence, our study aimed to evaluate the effect of potential shifts in dietary patterns on T2DM risk in French West Indian adults according to several scenarios.

METHODS

We used a cross-sectional multistage sampling survey on dietary intake conducted in 2013 on a representative sample of Guadeloupeans and Martinicans adults (n = 1063). From previously identified current dietary patterns, we used PRIME-Diabetes, a comparative risk assessment model, to estimate the effect of potential shifts from the "transitioning" pattern to the "convenient," the "prudent," and the "traditional" ones on T2DM risks.

RESULTS

Potential shift in dietary intakes from the "transitioning" pattern to the "traditional" one reduced the T2DM risk in women (- 16% [- 22; - 10]) and in men - 14% [- 21; - 7]), as the shift in dietary intakes toward the "prudent" pattern (- 23% [- 29; - 17] and - 19% - 23; - 14], respectively). These risk reductions were mostly driven by increased whole grains, fruits, green leafy vegetable intakes, and decreases in potatoes, red meats, processed meats, and sugar-sweetened beverages. The shift in dietary intakes toward the "convenient" pattern did not affect the T2DM risks.

CONCLUSION

To curb the increase in T2DM prevalence and reduce this burden, one public health action could be to target transitioning adults and help them to shift towards a diet associated with a reduced risk of T2DM as a prudent or a traditional diet.

The Effectiveness of Implementation of Healthy Living Community Movement in Overcoming Metabolic Syndrome Among Female Workers in East Kalimantan, Indonesia

The metabolic syndrome occurs in almost 25% of the world’s adult population. A workplace is an ideal place for implementing health interventions to reduce metabolic syndrome risk factor. One of the Indonesian government’s health programs to improve public health and prevent non-communicable diseases is called Healthy Living Community Movement (HLCM). This research aims to determine the effectiveness of HLCM implementation to overcome metabolic syndrome among female workers in Indonesia. This quasi-experimental study included 42 female workers with metabolic syndrome, which were divided into an intervention group and a control group. The intervention group was given an 8-weeks combination of health education and implementation of HLCM activities that consisted of fruit and vegetables provision as much as 400 grams per day and physical exercise for at least 150 minutes per week. The intervention for control group included only health education. Subjects’ parameters were measured and adherence to HLCM activities was evaluated by a questionnaire. Adherence to HLCM implementation was carried out by 52.4% of the subjects which resulted in a significant reduction in their waist circumference, systolic and diastolic blood pressure, and triglyceride levels (p < 0.05, respectively). After 8 weeks of interventions, 13 subjects (65%) from the intervention group were no longer included in the metabolic syndrome criteria, while in the control group only 2 subjects (10.5%) were not included. Therefore, the implementation of HLCM in the workplace is effective in overcoming the metabolic syndrome.

Is Loneliness an Undervalued Pathway between Socio-Economic Disadvantage and Health?

Loneliness is a growing public health issue. It is more common in disadvantaged groups and has been associated with a range of poor health outcomes. Loneliness may also form an independent pathway between socio-economic disadvantage and poor health. Therefore, the aim of this study was to explore the contribution of loneliness to socio-economic health inequalities. These contributions were studied in a Dutch national sample (n = 445,748 adults (≥19 y.o.)) in Poisson and logistic regression models, controlling for age, gender, marital status, migration background, BMI, alcohol consumption, smoking, and physical activity. Loneliness explained 21% of socioeconomic health inequalities between the lowest and highest socio-economic groups in self-reported chronic disease prevalence, 27% in poorer self-rated health, and 51% in psychological distress. Subgroup analyses revealed that for young adults, loneliness had a larger contribution to socioeconomic gaps in self-rated health (37%) than in 80+-year-olds (16%). Our findings suggest that loneliness may be a social determinant of health, contributing to the socioeconomic health gap independently of well-documented factors such as lifestyles and demographics, in particular for young adults. Public health policies targeting socioeconomic health inequalities could benefit from integrating loneliness into their policies, especially for young adults.

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.

Immediate impacts of COVID-19 crisis on agricultural and food systems in the Caribbean

CONTEXT

In a region already plagued by food insecurity and challenges to the sustainability of the agricultural sector, the COVID-19 pandemic was a brutal shock in the Caribbean with immediate and significant socio-economic consequences.

OBJECTIVE

In this paper, we assessed what are the immediate impacts of the COVID-19 crisis on the agricultural and food systems of the Caribbean.

METHODS

To this end, we conducted online surveys among farmers, households and experts of the region. We assessed the nature, strength and reversibility of the impacts but also the factors of resilience in the face of the crisis.

RESULTS AND CONCLUSIONS

Our study shows that the COVID-19 crisis has had strong impacts on Caribbean farmers and has weakened agricultural systems. The main impacts identified were a drop in income, production losses due to difficulties in marketing through conventional channels, but also difficulties in managing the farming systems due to reduced access to inputs and labor. In order to cope, farmers have adapted to be more self-sufficient: reduction in the size of cultivated areas, search for short marketing channels, diversification of production and reorientation towards the needs of the local market, recourse to mutual aid between farmers. If these effects appear to be non-irreversible in an island like Guadeloupe, the situation is different in other islands of the region where farmers have had to sell livestock, seek new off-farm income and sometimes sell land to cope. In terms of impacts on food systems, the crisis has led to strong constraints such as a reduction in food intake and diversity and increased reliance on family and social mutual aid. Our study also shows that the crisis has had an impact on consumer behavior and their perception of the importance of the agricultural sector: reduction of food waste, return to fresh and local products, adaptation of the diet, consumption of new products, and cultivation of food gardens. Finally, our study shows that the crisis has had an effect of strengthening the links between farmers and the rest of the population.

SIGNIFICANCE

Thus if the crisis has had seriously damaging consequences, it can also be the trigger and catalyst for an agro-ecological transition and the development of a circular and territorialized bio-economy to strengthen the resilience of Caribbean agricultural and food systems and facilitate the achievement of sustainability and food security objectives.

Metabolic dysregulation in older adults with depression and loneliness: The ATHLOS study

This study aimed to examine how loneliness contributes to metabolic dysregulation among older adults with depression and determine the relative contribution of loneliness to the development of chronic diseases in late adulthood. Harmonised data from the Ageing Trajectories of Health: Longitudinal Opportunities and Synergies (ATHLOS) project were used. Concretely, the sample comprised 6195 participants (53.95% women; M = 61.30 years, SD = 7.11) from three European cohorts. Three groups were considered: control group (CG); depressive symptom episode group (DEP); and a group with depression and loneliness (DEP + LONE). A metabolic score was estimated using anthropometric and blood indicators, by means of multi-indicator multi-causes (MIMIC) modelling and after controlling for sociodemographic and health-related covariates. Group-comparison was based on measurement-invariance procedures. Multimorbidity development was predicted at follow-up considering the study group and relevant covariates. All the analyses were sex-specific. As a result, measurement invariance revealed the influence of group (ΔCFI = -0.017 for male participants and ΔCFI = -0.009 for female ones) on metabolic scores in both sexes. Metabolic scores were significantly lower (i.e., they had more metabolic risk) in DEP + LONE women in comparison to women from the other groups. DEP men showed the lowest metabolic scores but those from the DEP + LONE group showed meaningfully lower scores than CG men (d = 1.35). In terms of multimorbidity prediction, DEP + LONE group membership significantly predicted the outcome in both sexes; DEP group membership significantly predicted multimorbidity at follow-up in women. In summary, these results highlight the relevant contribution of loneliness in depression-related metabolic dysregulation in the short- (concurrent metabolic risk) and long-term (chronic condition development). Moreover, sex-specific mechanisms seem to be involved in metabolic alterations of depressed people showing loneliness feelings. This study calls for action to reduce the impact of loneliness in old age and to promote healthy ageing.

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.
