Int J Environ Res Public Health
August 2023
Article Synopsis
- * It analyzed data from the ELSA-Brasil cohort and found that higher physical activity and lower sedentary time were linked to reduced abdominal obesity, especially in men and menopausal women.
- * The findings highlight the importance of maintaining an active lifestyle and reducing sedentary behavior to combat abdominal obesity across different demographics.
Objective: to determine the rate of hospitalizations due to acute non-drug poisoning (NDP) events and to analyze mortality arising from these health conditions in Brazil from 2009 to 2018.
Methods: this was a time-series study using Prais-Winsten regression to analyze records of hospitalizations for "treatment of intoxication or poisoning due to exposure to non-drug substances" held on the Hospital Information System.
Results: there were 125,570 hospitalizations due to NDP.
Article Synopsis
- A study was conducted in Brazil to estimate the prevalence of vitamin D levels among healthy adults and examine how factors like lifestyle and demographics affect these levels.
- The study involved 1,004 blood donors from Salvador, São Paulo, and Curitiba, measuring their 25-hydroxyvitamin D (25(OH)D) and parathyroid hormone (PTH) levels while analyzing data related to lifestyle and demographics.
- Results showed that 15.3% of participants were vitamin D deficient and 50.9% were insufficient, with variations across the three cities, indicating a notable impact from factors like body mass index, sun exposure, and skin color on vitamin D status.
Objective: To estimate the incidence of hospitalizations considering drug intoxication and the mortality of these diseases in Brazil, given trends from 2009 to 2018.
Methods: Data on hospital admissions and deaths come from DATASUS and demographic data from the Brazilian Institute of Geography and Statistics (IBGE). Hospital admissions with Autorização para Internação Hospitalar (AIH - Authorization for Hospital Admission) indicated as a procedure "treatment of intoxication or poisoning due to exposure to drugs and substances for non-drug use" were selected, with only cases of hospitalization due to drug intoxication being analyzed.

Arch Endocrinol Metab
November 2021
Objective: To evaluate incidence of subclinical and overt hyperthyroidism and hypothyroidism.
Methods: The Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) is a prospective cohort study of 15,105 civil servants, examined at baseline and over a 4-year follow-up. This analysis included 9,705 participants with normal thyroid function at baseline, follow-up information about thyroid function and with no report of using drugs that may interfere in the thyroid function.
Low coverage of HPV vaccination in the national immunization programme in Brazil: Parental vaccine refusal or barriers in health-service based vaccine delivery?
PLoS One
April 2019
Article Synopsis
- - The World Health Organization supports HPV vaccination in national immunization programs (NIP), but global vaccination rates are still low; this study examined HPV vaccine coverage and parental acceptance in Brazil after its inclusion in the NIP.
- - A survey of 826 parents in major Brazilian cities revealed high acceptance of the vaccine (92% for daughters, 86% for sons), with misinformation about HPV and the vaccine contributing to lower vaccination rates.
- - Despite the high parental acceptance, the study found that only 58.4% of eligible girls received two doses, largely due to issues in vaccine delivery and missed opportunities at health-care centers rather than outright refusal by parents.
Generational differences in dietary pattern among Brazilian adults born between 1934 and 1975: a latent class analysis.
Public Health Nutr
November 2018
Objective: To identify generational differences in the dietary patterns of Brazilian adults born between 1934 and 1975.
Design: A cross-sectional study from the baseline of the multicentre Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) cohort. Year of birth was categorized into three birth generations: Traditionalists (born between 1934 and 1945); Baby Boomers (born between 1946 and 1964); and Generation X (born between 1965 and 1975).
Aims: To determine the prevalence of inadequate glycemic control and its correlates in a large multicenter survey of Venezuelan patients with diabetes.
Methods: A cross-sectional study in a sample of adult patients with diabetes, attending health centers in Venezuela. Information about diabetes, current medications, complications, and diet were obtained by trained interviewers, using a standardized questionnaire.
