[Food insecurity in rural communities in Northeast Brazil: does belonging to a slave-descendent community make a difference?]

Ultra-processed food consumption and metabolic syndrome: a cross-sectional study in Quilombola communities of Alagoas, Brazil

BACKGROUND

The processing of food can cause changes that turn them into risk factors for chronic diseases. A higher degree of food processing is associated with the development of chronic non-communicable diseases (NCDs), including the metabolic syndrome (MetS). The objective of this study was to analyze the relationship between ultra-processed food (UPF) consumption and the prevalence of MetS and its risk factors, focusing on a population group especially subjected to precarious living conditions and food insecurity.

METHOD

Cross-sectional population-based study with women (19 to 59 years) from Quilombola communities of Alagoas. The socioeconomic, demographic, anthropometric, health status, lifestyle, and food intake (24-h recall) variables were analyzed. The dependent variable was the MetS, defined using the harmonization criteria of the Joint Interim Statement, and its components. The foods consumed were categorized according to the Nova Classification, assuming the highest UPF consumption as risk exposure. The measure of association was the prevalence ratio (PR) and respective 95%CI, calculated by Poisson regression with robust variance. We also analyzed the association with the Nova score of UPF consumption.

RESULTS

We investigated 895 women (38.9 ± 11.0 years), of whom 48.3% had MetS. On average, 15.9% of the total energy intake came from UPF. Lower Nova scores were associated with a lower prevalence of diabetes and low HDL. Higher UPF consumption was associated with a 30% higher prevalence of hypertension (PR = 1.30; 95%CI: 1.06-1.61).

CONCLUSION

The highest UPF consumption was positively associated with the prevalence of hypertension, while a lower Nova score was a protective factor against diabetes and low HDL. UPF consumption in Quilombola communities is important but lower than that observed in the Brazilian population in general. It is suggested that public health programs be implemented to promote healthy eating while valuing the existing eating habits and traditions among the remaining Brazilian Quilombola people.

Hypertension in Quilombola children and adolescents

ABSTRACT

To determine the prevalence of prehypertension (PH) and hypertension (AH) in quilombola children and adolescents, as well as to analyze sociodemographic, behavioral, and health characteristics.Prevalence study conducted in random samples of quilombola children and adolescents from 06 to 19 years of age, in remaining quilombo communities in Cachoeira-Bahia. Identification, sociodemographic, behavioral, anthropometric, and blood pressure (BP) data were used. Descriptive analyses of the variables of interest were performed based on absolute (N) and included frequencies (percentage, prevalence). Pearson's Chi-square (χ2) and Fisher Exact tests determined possible differences.Of the 668 participants, 54.3% were children, 51.2% were male, and 29.4% presented alterations in BP. PH and AH were found in 12.7% and 14.3% of the children, respectively; for adolescents, these values were 12.5% and 15.4%, respectively. No statistically significant difference was found between the prevalence of AH in the 2 population groups, nor between the PH measurements. Most families reported a low socioeconomic status. Among children, 6.6% were underweight, 14.6% were overweight, 10.7% were obese, 12.7% presented a Waist-to-Height Ratio (WHtR) > 0.5; 70.1% were inactive and 88.4% had a sedentary lifestyle; 5.6% of the adolescents were underweight, 12.8% were overweight, 9.2% were obese, 11.5% presented a WHtR > 0.5; 78% were inactive and 92.1% had a sedentary lifestyle. Normotensive children and adolescents, and those with alterations in BP differed only in terms of the Body Mass Index (P = .007) and WHtR (P < .001). The consumption of unhealthy foods was high.The high prevalence of PH and AH, as well as of exposure to potential risk factors for AH in quilombola children and adolescents, reveals a worrisome situation, and demands further studies to identify risk factors for this disease and the need for interventions beyond the health sector, especially as regards disease prevention and control in the early stages of life, aiming to reduce its prevalence as adults.

Overweight in Rural Quilombola and Non-quilombola Adolescents From the Northeast of Brazil

Introduction: Overweight is an emerging problem among children and adolescents that leads to the development of several morbidities and health risks. Overweight occurs differently in different populations, especially in vulnerable groups like the rural and quilombola communities (an African-descendant population). This study aimed to estimate the prevalence of overweight and to investigate the possible associated factors in rural adolescents living in both quilombola and non-quilombola communities in Northeast Brazil.

Methods: This study is a population-based cross-sectional study with a household approach carried out in 2015 with 390 adolescents (age 10–19 years) living in rural quilombola and non-quilombola communities. The nutritional status was gauged using z-scores calculated for body mass index (BMI) and varies with gender and age. Prevalence ratios (PRs) and 95% confidence intervals (95% CIs) were used to establish associations between the results and explained variables. The multivariate analysis followed a model with a hierarchical entry of covariables controlled by gender and age.

Results: The study showed that 18.5% of rural adolescents were overweight, of which 17.9% were quilombolas and 19.0% were non-quilombolas. A significant difference in overweight between the samples was not found. In the multivariate-adjusted model, age ≥16 years (PR: 0.51; 95% CI: 0.28–0.95), the habit of having regular breakfast (PR: 0.58; 95% CI: 0.35–0.98), and process of attending school (PR: 0.35; 95% CI: 0.17–0.71) were associated with a lower prevalence of overweight. Stationary screen time, in contrast, was associated with a higher prevalence (PR: 1.61; 95% CI: 1.05–2.46). The process of attending school was associated with a lower prevalence of overweight (PR: 0.26; 95% CI: 0.09–0.69), even for the quilombolas.

Conclusions: A low prevalence of overweight was identified in rural adolescents. Overweight was significantly associated with the habit of having regular breakfast, older age, stationary screen time, and the process of attending school. The results reveal that school is a potential space for health promotion interventions, specifically in the most vulnerable rural regions, such as the quilombola communities. Besides, the study emphasizes the importance of adopting a healthy lifestyle early in life, including cultivating the habit of having regular breakfast and reducing stationary screen time.

Access to Health Services and Assistance Offered to the Afro-Descendant Communities in Northern Brazil: A Qualitative Study

The remnants of quilombos, individuals of African descent, have faced several barriers throughout its history, either due to prejudice imposed by society, or the non-fulfillment of their rights guaranteed in the 1988 Constitution, such as access to health services. Thus, this study aims to evaluate the health care offered to quilombo communities in the northern region of Tocantins. This is an exploratory, descriptive study with a qualitative approach, including field research and focus group, carried out with 58 quilombo remnants people from communities in the northern region of Tocantins. Data collection was carried out between from October 2017 to July 2018, through semi-structured interviews. We found that these communities have limited access to health services, in addition to a negative perception of the assistance offered to the health of their population and the commitment of managers. Therefore, access to health and assistance received by the studied communities required to be prioritized since the care provided is not unique and has not met the health demands and needs of the remaining quilombos in northern Tocantins, Brazil.
