Diet and Lifestyle Changes During the COVID-19 Pandemic in Ibero-American Countries: Argentina, Brazil, Mexico, Peru, and Spain.

This study aimed to evaluate changes in dietary and lifestyle habits during the period of confinement due to the first wave of the COVID-19 pandemic in Ibero-American countries. A cross-sectional investigation was conducted with 6,325 participants of both genders (68% women), over 18 years of age and from five countries: Brazil (N = 2,171), Argentina (N = 1,111), Peru (N = 1,174), Mexico (N = 686), and Spain (N = 1,183). Data were collected during the year 2020, between April 01 and June 30 in Spain and between July 13 and September 26, in the other countries studied using a self-administered online survey designed for the assessment of sociodemographic, employment, physical activity, health status, and dietary habits changes. Most participants (61.6%), mainly those from Spain, remained constant, without improving or worsening their pattern of food consumption. Among those who changed, a pattern of better eating choices prevailed (22.7%) in comparison with those who changed toward less healthy choices (15.7%). Argentina and Brazil showed the highest proportion of changes toward a healthier pattern of food consumption. Peruvians and Mexicans were less likely to make healthy changes in food consumption (OR: 0.51; 95% CI: 0.4-0.6 and OR: 0.69; 95% CI: 0.4-0.8, respectively), when compared to Argentinians. Most respondents did not change their pattern of meal consumption, but those who did reduced their consumption of main meals and increased intake of small meals and snacks. Although most participants affirmed to be doing physical activity at home, about one-half reported perception of weight gain. Individuals with alterations in sleep pattern (either by increasing or decreasing sleep time) were more likely to change their diets to a healthier pattern. In contrast, individuals with confirmed diagnosis of COVID-19 and those who reported feeling anxious were more likely to perform changes to a less healthy eating pattern (OR: 1.72; 95% CI: 1.2-2.3 and OR: 1.21; 95% CI: 1.1-1.4, respectively). In conclusion, although most participants remained constant in their eating habits, lifestyle changes and anxiety feelings were reported. Among those who changed patterns of food consumption, healthier choices prevailed, with differences between countries. However, there were alterations in the distribution of meals, with higher consumption of snacks and small meals. These results can be used to guide policies to prevent deleterious consequences that may affect the incidence of chronic diseases.

Social inequalities in health: duration of unemployment unevenly effects on the health of men and women.

BACKGROUND: Employment status is an important determinant of health inequalities. The aim of this article is to analyze the association between duration of unemployment and the presence of cardiovascular risk factors, self-perception of health and presence of depression and anxiety, assessing differences in the effects of unemployment by sex and age. METHODS: The sample was composed of 12 123 people (52.4% men), 18 to 74 years old (mean age= 43.5 years, SD = 10.4). Logistic regression analyses were used to study the influence of duration of unemployment on health ('0 days', '≤11 months' and '≥12 months'). Sex, age, level of education, employment status and time spent unemployed, as well as tobacco and alcohol use and physical activity, were considered. Morbidity variables were hypertension, hypercholesterolemia, diabetes, obesity, depression and anxiety, and a subjective health assessment. RESULTS: The results showed both unemployed men and women had worse outcome in health compared with their active counterparts. The risk of hypertension was presented in long-term unemployed men, which had 1.3 times more likely to suffer from hypertension. The risk of obesity was presented only in unemployed women, which had 1.5 times more risk of obesity, doubling the risk (OR= 2.2) among women under age 40. The unemployment had a protective effect against anxiety among younger women (OR = 0.53). CONCLUSION: It has been observed a different influence of unemployment time on men and women's health. The employment status should be considered in public health policy agendas with the purpose of reducing inequalities in health.

Static cut-points of hypertension and increased arterial stiffness in children and adolescents: The International Childhood Vascular Function Evaluation Consortium.

Pediatric elevated blood pressure (BP) and hypertension are usually defined using traditional BP tables at the 90th and 95th percentiles, respectively, based on sex, age, and height, which are cumbersome to use in clinical practice. The authors aimed to assess the performance of the static cut-points (120/80 mm Hg and 130/80 mm Hg for defining elevated BP and hypertension for adolescents, respectively; and 110/70 mm Hg and 120/80 mm Hg for children, respectively) in predicting increased arterial stiffness. Using data from five population-based cross-sectional studies conducted in Brazil, China, Korea, and New Zealand, a total of 2546 children and adolescents aged 6-17 years were included. Increased arterial stiffness was defined as pulse wave velocity ≥sex-specific, age-specific, and study population-specific 90th percentile. Compared to youth with normal BP, those with hypertension defined using the 2017 American Academy of Pediatrics guideline (hereafter referred to as "percentile-based cut-points") and the static cut-points were at similar risk of increased arterial stiffness, with odds ratios and 95% confidence intervals of 2.35 (1.74-3.17) and 3.07 (2.20-4.28), respectively. Area under the receiver operating characteristic curve and net reclassification improvement methods confirmed the similar performance of static cut-points and percentile-based cut-points (P for difference > .05). In conclusion, the static cut-points performed similarly well when compared with the percentile-based cut-points in predicting childhood increased arterial stiffness. Use of static cut-points to define hypertension in childhood might simplify identification of children with abnormal BP in clinical practice.

Carotid-Femoral Pulse Wave Velocity in Healthy Spanish Children: Reference Percentile Curves.

Carotid-femoral pulse wave velocity (cfPWV) measurement is an appropriate method for determining arterial stiffness and is a useful tool for early detection of cardiovascular disease. However, the lack of reference values due to the difficulty in accessing healthy child populations, among other causes, has limited its use in clinical practice. The aim of this study was to create reference cfPWV percentile curves for healthy children. The initial sample consisted of 350 girls and boys aged 8 to 11 years. The cfPWV per age and sex were generated using the lambda-mu-sigma (LMS) technique. The effects of sex, age, arterial pressure, and body mass index were taken into account. The main result of this study is the age- and height-specific cfPWV reference percentile curves for girls and boys. Curves were obtained for both sexes, since sexual differences were observed in growth and development rates that may affect cfPWV.

Maternal plasma antioxidant status in the first trimester of pregnancy and development of obstetric complications.

INTRODUCTION: Oxidative stress is present in pregnancy complications. However, it is unknown if early maternal antioxidant status could influence later development of complications. The use of assisted reproduction techniques (ART) is rising due to the delay of first pregnancy and there is scarce information on its influence on oxidative balance. OBJECTIVE: To assess the possible relationship between maternal plasma antioxidant status in first trimester of gestation with later development of pregnancy complications, evaluating the influence of ART and nutrition. METHODS: Plasma from 98 healthy pregnant women was obtained at week 10, nutrition questionnaires filled and women were followed until delivery. We evaluated biomarkers of oxidative damage (carbonyls, malondialdehyde-MDA), antioxidants (thiols, reduced glutathione, phenolic compounds, catalase and superoxide dismutase activities) by spectrophotometry/fluorimetry and melatonin (ELISA). Antioxidant status score (Antiox-S) was calculated as the computation of antioxidants. Diet-antioxidants relationship was evaluated through multiple correspondence analysis. RESULTS: Melatonin and carbonyls exhibited a negative correlation. No difference in oxidative damage was found between groups, but Antiox-S was significantly lower in women who developed complications. No differences in oxidative damage or Antiox-S were found between ART and no-ART pregnancies. High consumption of foods of vegetable origin cluster with high plasma levels of phenolic compounds and with high Antiox-S. CONCLUSIONS: In early normal gestation, low plasma antioxidant status, assessed through a global score, associates with later development of pregnancy complications. Larger population studies could help to determine the value of Antiox-S as predictive tool and the relevance of nutrition on maternal antioxidant status.
