Sociodemographic determinants of multimorbidity in Brazilian adults and older adults: a cross-sectional study

Multimorbidity in the elderly of an educational program in Brazilian capital: A cross-sectional study

Population aging generated changes in the epidemiological profile and culminated in a high frequency of diseases. The objective of this study was estimating the prevalence of multimorbidity and the associated variables in the elderly of an educational program in the Federal District of Brazil. This is a cross-sectional study with data collection carried out during the period from December 2022 to April 2023 by means of telephone calls. Multimorbidity was defined as a concomitant presence of 2 or more noncommunicable chronic diseases. One-hundred fifty individuals aged between 60 and 82 years old participated in the study. The median number of self-reported diseases was 2, ranging from 0 to 9. The estimated prevalence of multimorbidity was 69.3%, being higher among elderly individuals self-reporting their health as regular or bad/or very bad, having systemic arterial hypertension, diabetes mellitus, dyslipidaemia, hypothyroidism, overweight/obesity, and depression, including polypharmacy (P < .05). The high rate of multimorbidity and associated variables shows the importance of an integrated approach on health services focused on promoting health and preventing health impairment to favor the quality of life during aging.

Physical activity among older adults with multimorbidity: Evidence from a population-based health survey

INTRODUCTION

The promotion of physical activity has been recognized as an important component in the management and prevention of multimorbidity, a condition that is increasing prevalent worldwide, including in Brazil. However, there is a scarcity of studies exploring the disparity in physical activity levels between individuals with and without multimorbidity. Therefore, the study aimed to estimate the prevalence of multimorbidity and physical activity among older adults, as well as analyze the relationship of a sufficient level of physical activity and multimorbidity, while considering sociodemographic characteristics of residents in São Paulo, Brazil.

MATERIALS AND METHODS

Data from 1.019 participants aged 60 years or older (59.7% female; mean age 69.7±7.7) were collected from the Health Survey (ISA-Capital, 2015) conducted in the city of São Paulo, Brazil. We defined multimorbidity as the presence of two or more chronic conditions, and for physical activity, classified a sufficient level (≥150 min/week). Prevalence Ratios (PR) with 95% Confidence Intervals (95%CI) were estimated using univariate and multivariate Poisson regression to examine the relationship between multimorbidity and sufficient level of physical activity.

RESULTS

67.7% of the participants lived with multimorbidity, while 30.1% had achieved a sufficient level of physical activity. There was a higher prevalence of sufficient level of physical activity among older adults with two (PR = 1.38; 95%CI 1.02-1.88) and four (PR = 1.37; 95%CI 1.00-1.87) chronic conditions. Older adults with multimorbidity who were 70 years or older (PR = 1.77; 95%IC 1.13-2.77), female (PR = 1.65; 95%CI 1.16-2.36), without a partner (PR = 1.43; 95%IC 1.03-1.99), and had a per capita income of 1 to 2.5 (PR = 1.83; 95%IC 1.00-3.33) were more likely to achieve a sufficient level of physical activity compared to their peers without multimorbidity.

CONCLUSIONS

The study highlights sociodemographic disparities in the sufficient level of physical activity among multimorbidity, suggesting the importance of considering these factors when planning public policies aimed at promoting physical activity.

Prevalence and factors associated with multimorbidity in adults in Brazil, according to sex: a population-based cross-sectional survey

Introduction

Multimorbidity, defined as the coexistence of two or more chronic diseases in the same individual, represents a significant health challenge. However, there is limited evidence on its prevalence and associated factors in developing countries, such as Brazil, especially stratified by sex. Thus, this study aims to estimate the prevalence and analyze the factors associated with multimorbidity in Brazilian adults according to sex.

Methods

Cross-sectional population-based household survey carried out with Brazilian adults aged 18 years or older. The sampling strategy consisted of a three-stage conglomerate plan. The three stages were performed through simple random sampling. Data were collected through individual interviews. Multimorbidity was classified based on a list of 14 self-reported chronic diseases/conditions. Poisson regression analysis was performed to estimate the magnitude of the association between sociodemographic and lifestyle factors with the prevalence of multimorbidity stratified by sex.

Results

A total of 88,531 individuals were included. In absolute terms, the prevalence of multimorbidity was 29.4%. The frequency in men and women was 22.7 and 35.4%, respectively. Overall, multimorbidity was more prevalent among women, the older people, residents of the South and Southeast regions, urban area residents, former smokers, current smokers, physically inactive, overweight, and obese adults. Individuals with complete high school/incomplete higher education had a lower prevalence of multimorbidity than those with higher educational level. The associations between education and multimorbidity differed between sexes. In men, multimorbidity was inversely associated with the strata of complete middle school/incomplete high school and complete high school/incomplete higher education, while in women, the association between these variables was not observed. Physical inactivity was positively associated with a higher prevalence of multimorbidity only in men. An inverse association was verified between the recommended fruit and vegetable consumption and multimorbidity for the total sample and both sexes.

Conclusion

One in four adults had multimorbidity. Prevalence increased with increasing age, among women, and was associated with some lifestyles. Multimorbidity was significantly associated with educational level and physical inactivity only in men. The results suggest the need to adopt integrated strategies to reduce the magnitude of multimorbidity, specific by gender, including actions for health promotion, disease prevention, health surveillance and comprehensive health care in Brazil.

Prevalence risk of sarcopenia in older Brazilian adults during the pandemic: A cross-sectional analysis of the Remobilize Study

BACKGROUND

Social distancing has led to lifestyle changes among older adults during the coronavirus disease 2019 (COVID-19) pandemic.

OBJECTIVES

This study aimed to estimate the prevalence risk of sarcopenia (RS) and investigate its associated factors during the COVID-19 pandemic in older Brazilian adults.

DESIGN AND SETTING

Cross-sectional observational analysis of baseline data as part of the Remobilize Study.

METHODS

Participants in the study were older adults (≥ 60 years), excluding those who were bedridden or institutionalized. The data collected consisted of answers about the RS (SARC-F), functional status, walking, sedentary behavior (SB), pain, comorbidity, and life space mobility.

RESULTS

A total of 1,482 older adults (70 ± 8.14 years, 74% women) participated in the study, and an RS prevalence of 17.1% was found. (95% confidence interval [CI] 15.25-19.15%). The adjusted multivariate model showed a significant association between RS and functional limitation (odds ratio [OR]: 19.05; CI 13.00-28.32), comorbidity (OR: 5.11; CI 3.44-7.81), pain (OR: 4.56; CI 3.33-6.28), total walking (OR: 0.99; CI 0.99-1.00), SB of 8-10 hours (OR: 1.85; CI 1.15-2.93), and SB of > 10 hours (OR: 3.93; CI 2.48-6.22). RS was associated with mobility during the pandemic (OR: 0.97; CI 0.96-0.98). P < 0.05.

CONCLUSIONS

During the pandemic, the prevalence of RS in older Brazilians was estimated at 17.1%. Moderate to severe functional limitation, comorbidities, presence of pain, walking, longer SB period, and reduced life space mobility significantly contributed to RS in older adults during the pandemic.
