Barriers to physical activity among adults in primary healthcare units in the National Health System: a cross-sectional study in Brazil

BACKGROUND

Many factors may negatively impact physical activity (PA), but studies lack evidence of individual predictors of perceived barriers to PA among adults in primary healthcare units.

OBJECTIVE

To analyze associations between sociodemographic characteristics, health conditions, leisure-time physical activity (LTPA), PA counseling and perceived barriers to LTPA among adult patients in primary healthcare units of the National Health System in Brazil.

DESIGN AND SETTING

Cross-sectional study on a representative sample of adults in primary healthcare units in São José dos Pinhais, Paraná, Brazil.

METHODS

This study was conducted in 2019, among 779 adults (70% women). Barriers to LTPA, sociodemographic characteristics (sex, age, marital status, skin color, education and income), health conditions (body mass index, hypertension, diabetes, dyslipidemia, coronary disease and medications), LTPA level and PA counseling received were measured using validated, standardized procedures. The data were analyzed using chi-square and Mann-Whitney U tests.

RESULTS

The most prevalent barriers were "feeling too tired" (53%) and "lack of time" (52%). PA counseling was inversely associated with "lack of time" (45% versus 57%; P < 0.001) but positively associated with "injury or disease" (38% versus 29%; P = 0.008). There was an inverse linear trend between the number of barriers and LTPA (walking and total) (P < 0.001). Most barriers differed in comparisons of sociodemographic characteristics, health conditions, LTPA and counseling (P < 0.05).

CONCLUSIONS

The barriers vary according to the individual predictors. Counseling strategies need to be specific for each barrier and may be promising for promoting LTPA within primary healthcare.

Biopsychosocial inequality, active lifestyle and chronic health conditions: a cross-sectional National Health Survey 2013 in Brazil

This study estimated the biopsychosocial factors related to active physical behavior in the Brazilian population with and without chronic non-transmissible disease (NCD). Cross-sectional study of the National Health Survey (NHS) in Brazil, with 60,202 individuals in 2013. Participants were randomly selected by complex sampling. The outcome was physically active behavior measured by performing a minimum of 150 min of physical exercise per week. The independent variables were social and psychological characteristics, lifestyle and health. Cox regression was applied to estimate the prevalence ratio (PR). There are 29,666 (48.3%; 95% CI 47.0–50.0) participants reported having NCD. Not being a smoker or alcoholic, living in an urban area (PR = 1.44; CI95% 1.23–1.68/PR = 1.38; CI95% 1.08–1.75), having informal social support (PR = 1.26; CI95% 1.10–1.44/PR = 1.19; CI95% 1.05–1.34), A social class (PR = 0.43; CI95% 0.25–0.73/PR = 0.46; CI95% 0.26–0.80), high schooling (PR = 0.34; CI95% 0.23–0.51/PR = 0.33; CI95% 0.24–0.46) as well as paid work (PR = 0.87; CI95% 0.78–0.96/PR = 0.89; CI95% 0.79–0.99) are more associated with active lifestyle in both groups. However, only in the group without NCD, the male sex (PR = 1.42; CI95% 1.28–1.57), no having some disability (PR = 1.31; CI95% 1.03–1.66) and having private health insurance (PR = 1.26; CI95% 1.13–1.41) were more associated with active behavior, while in the group with NCD, being elderly (PR = 1.22; CI95% 1.05–1.42), not be white (PR = 0.85; CI95% 0.77–0.95) and not having restful sleep (PR = 1.23; CI95% 1.08–1.40) are associated with active lifestyle. People with and without NCD in Brazil have very close active behavior, however, some biopsychosocial factors such as: sex, age, lifestyle, socioeconomic level are unevenly associated with the active lifestyle in the groups. Thus, therapeutic or preventive proposals as well as public policies for health promotion must observe these distinctions when elaborating their actions.

Dietary and nutrient intake among participants of a Brazilian health promotion programme: a cross-sectional study

OBJECTIVE

Developing health promotion activities, aimed at healthy food intake, is essential for improving quality of life and reducing the prevalence of chronic diseases. Thus, the objective of this study is to describe both dietary and nutrient intake, according to length of participation in a health promotion service (Programa Academia da Saúde - PAS).

DESIGN

A cross-sectional study was carried out with a representative sample of PAS units in vulnerable areas of the city. Dietary and nutrient intake were assessed, using the average of two 24-h recalls. Food was categorised according to the NOVA (a systematic grouping of all foods according to the nature, extent and purpose of the industrial processes they undergo) classification. The length of participation in PAS is presented in months and is then examined in tertiles for analysis.

SETTING

Belo Horizonte - Brazil.

PARTICIPANTS

3372 adults (≥20 years).

RESULTS

Users in the third tertile of PAS (24·4-61·6 months) experienced less energy intake, lipids and ultra-processed foods, and more culinary preparations, compared to others. Users in the second (10·1-24·3 months) and third tertiles of PAS had higher carbohydrate intake, Ca and vitamin C v those in the first tertile (0-10 months).

CONCLUSIONS

Results suggest that greater participation in PAS can improve dietary and nutrient intake, showing its potential to promote healthy lifestyles, prevent chronic diseases and offer longitudinal health care.
