Food Insecurity Reduces the Chance of Following a Nutrient-Dense Dietary Pattern by Brazilian Adults: Insights from a Nationwide Cross-Sectional Survey

Lunch patterns of Brazilian adults and their association with socioeconomic and demographic characteristics: the 2017-2018 Brazilian National Dietary Survey

Lunch is an important meal in Brazil, with varying standards among different population groups. This study aims to determine the lunch dietary patterns of Brazilian adults and verify their association with socioeconomic and demographic characteristics. Data from the Brazilian National Dietary Survey were used, comprising 28,901 adults aged 19 to 59 years (excluding pregnant and lactating women). Food consumption was assessed via 24-hour recalls at the interviewee's home. A total of 1,832 food items were recorded, 1,120 of which were mentioned at lunch. Socioeconomic and demographic variables were obtained through a structured questionnaire. Dietary patterns were derived by factor analysis, considering the complexity of the sample. The mean scores and 95% confidence intervals for each dietary pattern were estimated across all levels of socioeconomic and demographic variables. Considering the complexity of the sampling design, all analyses were performed using the statistical package SAS OnDemand for Academics. In total, 3.4% of Brazilian adults reported not having lunch. In total, three patterns explained 30.7% of lunch variability: traditional Brazilian; salads; and protein-based meal with desserts and beverages. Men, individuals with less schooling, those with lower income, and residents of the Central-West and Northeast regions adhered more to the traditional pattern. Fruits did not play an essential role in any pattern. Adherence to dietary patterns varied according to socioeconomic and demographic factors.

Association between food insecurity and chronic noncommunicable diseases in Brazil: a systematic review

OBJECTIVE

To analyze the association of food insecurity (FI) with chronic noncommunicable diseases (NCDs) in the Brazilian context.

METHODS

The review protocol was registered with the International Prospective Register of Systematic Reviews (PROSPERO). The searches were conducted in LILACS and PubMed databases (September/2022). Observational studies carried out in the Brazilian population published since 2003 were included, in which: (1) the association of FI with NCDs was analyzed; and (2) the Brazilian Food Insecurity Scale was used. Studies on pregnant women and those that associated FI with cancer, sexually transmitted infections, and musculoskeletal and respiratory diseases were excluded. The studies were subjected to methodological quality assessment.

RESULTS

A total of 27 cross-sectional studies were included; nine used secondary data from national surveys, and the others used primary data. An association between FI and overweight and obesity in different age groups was verified in the studies.

CONCLUSION

The included articles did not produce evidence on other NCDs of interest to health in Brazil such as diabetes and high blood pressure. However, they corroborate the already-known relationship between obesity and FI. Studies on the topic, with a longitudinal design, should be encouraged.

Intake of Table Sugar and Their Corresponding Food Sources in Adults from the 2017-2018 Brazilian National Dietary Survey

Excessive intake of free sugars is associated with adverse health outcomes. Table sugar is one of the main dietary sources of free sugars; however, the amount added by Brazilian consumers in their culinary preparations is unknown. The aims were to estimate the daily intake of table sugar (g/day), its contribution to total energy intake (E%) and the main food groups that contribute to the intake of this sugar in a nationwide multi-ethnic sample of Brazilian adults (2017-2018 Brazilian National Dietary Survey). Based on two 24-h recalls adjusted for the within-person variation, the overall median table sugar intake was 14.3 g/day, corresponding to 3.2 E%. Males, individuals living in rural areas, with low income, low education and experiencing food insecurity had a higher intake of table sugar. The main food sources of table sugar were coffee (55.8%), juice (33.9%), milk-based preparations and smoothies (3.1%), powdered and processed juice (2.7%), whole milk (1.9%), and tea (1.6%). There are no recommendations regarding the limit of table sugar intake, but considering that the WHO limits the intake of free sugars to <10 E%, it is concluded that table sugar intake by Brazilians corresponds to about 30% of the upper recommended daily intake of free sugars.

Gender, skin color, and household composition explain inequities in household food insecurity in Brazil

It is well known that female-headed households (FHHs) are more likely to experience food insecurity (FI) than male-headed households (MHHs), however there is a dearth of evidence on how gender intersects with other social determinants of FI. Thus, this paper investigated changes in the prevalence of household FI in Brazil from 2004 to 2018 by the intersection of gender, race/skin color and marital status of the household reference person. Data from three cross-sectional nationally representative surveys that assessed the status of FI using the Brazilian Household Food Insecurity Measurement Scale were analyzed (N2004 = 107,731; N2013 = 115,108, N2018 = 57,204). Multinomial logistic regression models were used to examine the relationship between profiles of gender, race/skin color, marital status of the head of the household with household FI stratified by the presence of children <5 years of age. Over time, FHHs had a higher prevalence of mild and moderate/severe FI than did households headed by men. Food security prevalence increased from 2004 to 2013 and decreased between 2013 and 2018 for households headed by men and women. In 2018, households headed by black/brown single mothers with children < 5 years of age were at the highest FI risk. The probability of reporting moderate/severe FI in these households were 4.17 times higher (95% CI [2.96-5.90]) than for households headed by married white men. The presence of children in the household was associated with a higher probability of moderate/severe FI, especially for households headed by black/brown individuals regardless of the reference person's gender. The results suggest that gender inequities combined with darker skin color and the presence of children at home potentiate the risk of moderate/severe FI. Policy makers need to consider the principles of intersectionality when investing in codesigning, implementing, evaluating, and scaling up evidence-based programs to reduce FI.

Factors associated with diet quality among Brazilian individuals with cardiovascular diseases

BACKGROUND

An individual's dietary pattern contributes in different ways to the prevention and control of recurrent cardiovascular events. However, the quality of the diet is influenced by several factors. The present study aimed to evaluate the quality of the diet of individuals with cardiovascular diseases and determine whether there is an association between sociodemographic and lifestyle factors.

METHODS

This is a cross-sectional study carried out with individuals with atherosclerosis (coronary artery disease, cerebrovascular disease or peripheral arterial disease) recruited from 35 reference centres for the treatment of cardiovascular disease in Brazil. Diet quality was assessed according to the Modified Alternative Healthy Eating Index (mAHEI) and stratified into tertiles. For comparing two groups, the Mann-Whitney or Pearson's chi-squared tests were used. However, for comparing three or more groups, analysis of variance or Kruskal-Wallis was used. For the confounding analysis, a multinomial regression model was used. p < 0.05 was considered statistically significant.

RESULTS

In total, 2360 individuals were evaluated: 58.5% male and 64.2% elderly. The median (interquartile range [IQR]) of the mAHEI was 24.0 (20.0-30.0), ranging from 0.4 to 56.0 points. When comparing the odds ratios (ORs) for the low (first tertile) and medium (second tertile) diet quality groups with the high-quality group (third tertile), it was observed that there was an association between diet quality with a family income of 1.885 (95% confidence intervals [CI] = 1.302-2.729) and 1.566 (95% CI = 1.097-2.235), as well as physical activity of 1.391 (95% CI = 1.107-1.749) and 1.346 (95% CI = 1.086-1.667), respectively. In addition, associations were observed between diet quality and region of residence.

CONCLUSIONS

A low-quality diet was associated with family income, sedentarism and geographical area. These data are extremely relevant to assist in coping with cardiovascular disease because they enable an assessment of the distribution of these factors in different regions of the country.

The PCOS puzzle: putting the pieces together for optimal care

Polycystic ovary syndrome (PCOS) is a multifaceted hormonal disorder that has significant ramifications for both women's reproductive and metabolic well-being. This analysis aims to offer a thorough comprehension of PCOS by investigating the various contributing factors that are crucial for its effective management. We delve into the topic of hormonal imbalances, such as elevated androgens and disrupted estrogen-progesterone dynamics, and their effects on reproductive and metabolic health. Furthermore, we explore the intricate connection between insulin resistance, hyperinsulinemia, and PCOS, highlighting their pivotal role in metabolic dysfunction. Additionally, we examine fertility challenges, irregular menstrual patterns, and metabolic complications while also reviewing current treatment methodologies. Moreover, we address the latest research concerning genetic, environmental, and epigenetic influences on PCOS. By piecing together these essential elements, healthcare professionals can attain a comprehensive understanding of PCOS and deliver optimal care for those affected by the condition.

Racial disparities in lifestyle habits and dietary patterns in university students during the COVID-19 pandemic

Objectives

To evaluate lifestyle habits and dietary patterns among university students during the COVID-19 pandemic and their association with skin color.

Methods

This cross-sectional study was conducted with 1315 undergraduate students from a public higher education institution. Sociodemographic characteristics, lifestyle habits, and food consumption were collected. Factor analysis was used to identify dietary patterns and multivariate logistic regression was conducted to estimate the associations between race/skin color and outcomes.

Results

Black individuals were less likely to show behaviors associated with the use of cigarettes or tobacco products (OR = 0.61; 95% CI 0.42-0.89). However, black individuals with higher income (greater than, or equal to one minimum wage per person) were less likely to show behaviors associated with illicit drug use (OR = 0.54; 95% CI 0.31-0.96), use of cigarettes or tobacco products (OR = 0.46; 95% CI 0.24-0.87) and alcohol consumption (OR = 0.64; CI 95% 0.42-0.98). In addition, individuals of race/skin color black with lower income (less than one minimum wage per person) showed decreased consumption of vegetables (OR = 0.68; CI 95% 0.48-0.96).

Conclusions

Black college students with higher income were less likely to show undesirable behaviors related to the use of psychoactive substances. In contrast, individuals with lower income had lower consumption of foods from the vegetable group, which can be considered an unfavorable health-related behavior.

Prevalence of Excess Sodium Intake and Their Corresponding Food Sources in Adults from the 2017–2018 Brazilian National Dietary Survey

Excessive sodium intake has been related to high blood pressure, a central risk factor for cardiovascular disease. In the present work, updated estimates of sodium intake, the main food sources, and the prevalence of excessive intakes in a nationwide multi-ethnic sample of Brazilian adults (2017–2018 Brazilian National Dietary Survey) were presented. Based on two 24-h recalls adjusted for the within-person variation, the overall median of sodium intake was 2432 mg. The prevalence of adults exceeding the recommended limits (tolerable upper limit, UL, and the chronic disease risk reduction cut-off point, CDRR) was 61% and 56%, respectively. The median sodium intake and proportion of individuals above the limits varied according to the subgroups evaluated. Males and adults (20–29 years) presented the highest excessive sodium intakes, and consequently, lowest adherence rates to UL and CDRR recommendations. The top food sources of sodium were white bread and toast (12.3%), beans (11.6%), white rice (10.6%), beef (7.7%), and poultry meat (5.5%). Given the health benefits of dietary sodium reduction, it would be advisable to enhance the current national initiatives of awareness and educational campaigns’ combined efforts to reduce sodium in processed foods to effectively decrease this micronutrient intake across the Brazilian population.
