Socioeconomic and demographic predictors of high blood pressure, diabetes, asthma and heart disease among adults engaged in various occupations: evidence from India

The frequency of asthma and its related factors: results of the enrolment phase of Tabari cohort study

INTRODUCTION

A large portion of the world's population has asthma. This study aimed to ascertain asthma prevalence and related factors in the Tabari cohort study (TCS).

METHODS

The TCS included 10,255 35-70-year-olds from urban and mountainous Sari (northern Iran) between June 2015 and November 2017. Education, occupation, domicile, socioeconomic position, history of psychiatric disorders, smoking (including hookah smoking), opium usage, and daily physical activity level were determined.

RESULTS

The final analysis included 9939 individuals. The asthma rate was 7.4%. Multiple factors increased asthma risk, according to statistical analysis. These factors included being female (OR, 1.337; 95% CI, 1.142-1.565), retired (OR, 1.553; 95% CI, 1.205-2.002), living in the city (OR, 1.268; 95% CI, 1.083-1.484), using opioids (OR, 1.689; 95% CI, 1.299-2.197), having lower socioeconomic status (SES) (OR, 0.723; 95% CI, 0.579-0.903), history of psychiatric disorders (OR, 2.313; 95% CI, 1.826-2.930), and aged 60-70 (OR, 2.325; 95% CI, 1.765-3.064), and BMI above 30 kg/m2 (OR, 1.499; 95% CI, 1.220-1.841). Several factors increased asthma probability in multivariate regression analysis. These factors include being female (OR = 1.389, p = 0.015), ages between 60 and 70 (OR = 2.034, p < 0.001), using opioids (OR = 1.940, p < 0.001), lower SES (OR = 0.738, p = 0.012), history of psychiatric disorders (OR = 2.035, p < 0.001), BMI above 30 kg/m2 (OR = 1.518, p < 0.001), and being a smoker (OR = 1.337, p = 0.056).

CONCLUSION

This study has identified that the prevalence of asthma in the Tabari cohort group is high. In addition, it was demonstrated that various factors are related to asthma.

Hypertension in Women: The Current Understanding and Future Goals

Hypertension is one of the major contributing risk factor of cardiovascular diseases. Despite enormous advances in the preventive cardiology, hypertension remains the leading cause of death and disability in women. The article aims to focus on the gender specific differences in hypertension, and existing gaps in the current understanding of high blood pressure (BP) in women. Apart from epidemiological differences, hypertension in men and women has distinct pathophysiological mechanisms, impact on cardiovascular system, awareness and control. Prevalence of hypertension is higher in men than women till menopause; following this the prevalence rises steeply in women, and exceeds that of men above 75 years of age. Women with their estrogenic environment are relatively protected from high BP as their hormonal/chromosomal profile govern expression of alternate renin angiotensin axis (RAS) pathway and anti-inflammatory, vasodilatory, anti-proliferative immune cells whereas in males, classical RAS driven inflammatory, pro-hypertensive and proliferative milieu confers higher risk of hypertension. Thus, immunotherapy can have a potential therapeutic role in the treatment of hypertension in future. Cardiovascular consequences of high BP are worse in women than men in majority of trials. Women are now getting more aware of hypertension but the control of BP still remains poorer than men, especially in older age group. There are some noteworthy pharmacokinetic and pharmacogenomics gender differences in response to various antihypertensive drugs, which can be taken into consideration while choosing a particular class of drugs in female population. Standard treatment guidelines recommend same BP targets and management strategies in both the genders, but the trials so far have not been designed in a way to draw women specific conclusions on optimal cut-offs for diagnosis and treatment of BP due to under representation of women in majority of trials. More women centered analysis in future hypertension research projects can provide better scientific insights in various clinical aspects of hypertension.

Prevalence and determinants of hypertension and associated comorbidities in non-pregnant women of reproductive age group (15-49 years): Evidence from National Family Health Survey (NFHS-4), India

Background

Hypertension in women is generally underestimated and undiagnosed as women are considered to be at a lower risk of cardiovascular disease than men in addition to gender-related differences in healthcare seeking behaviour and access to healthcare. As hypertension extends a substantial impact on the cardiovascular health of women and can pose an enormous burden on the healthcare systems in India, identification of its risk factors along with co-morbidities becomes necessary for planning of cardiovascular risk prevention, reduction and mitigation interventions.

Aim

This study aimed at estimating the prevalence and associated demographic and lifestyle risk factors of hypertension (HT) along with examining comorbidity patterns in women of reproductive age (15-49 years) in India.

Material and Methods

We analyzed data of 667,258 non-pregnant women of the reproductive age group (15-49 years) from the National Family Health Survey (NFHS)-4 dataset. We used maps to present the spatial patterns of HT in women across states and union territories and logistic regression modelling to identify associated factors.

Results

The overall prevalence of HT was 10.9% among women (15-49 years), with 60.7% of these having at least one comorbidity. While the prevalence of 'HT only' was higher in women 15-29 years of age (48.0%), the prevalence of HT with co-morbidities was higher in women aged ≥30 years (63.3%). Logistic regression analysis showed higher odds of 'HT and ³ two comorbidities' with age ³30 years (AOR 3.46, 95% CI 3.23-3.72), higher odds of 'HT only' with alcohol consumption (AOR 1.32, 95%CI 1.23-1.42), and higher odds of 'HT and one comorbidity' with BMI ³23 Kg/m² (AOR 1.17, 95%CI 1.14-1.21). Also, region-wise, the prevalence of HT was highest in the states of Uttar Pradesh (11.6%), Madhya Pradesh (8.0%), and Assam (6.9%).

Conclusion

The high prevalence of HT among women aged 15-49 years has serious medical, socio-economic, implications that warrant urgent and immediate gender-specific healthcare interventions. Along with lifestyle modifications, early and timely screening of HT, increasing awareness among young school-going girls, including rural areas, could flatten the HT population curve in India.

Association of work and hypertension among middle-aged adults and elderly Indians

PURPOSE

Over two-fifth of middle-aged adults and elderly (45 +) in India are hypertensive. Though studies examined prevalence, awareness and control of hypertension, little is known on the association of hypertension with work status in India. This study examines the variations of hypertension by types of work among middle-aged adults and the elderly in India.

METHODS

Data were drawn from the Longitudinal Aging Survey of India (LASI), Wave 1, 2017-18, and analysis was restricted to participants aged 45 and above with complete information on employment and blood pressure (N = 59,196).

RESULTS

We estimated the adjusted prevalence of hypertension at 49.2% (95% CI, 47.8-50.6) among the ever worked but not currently working and 44.5% (95% CI, 43.1-45.8) among currently working. Among eight broad categories of the currently working population, the adjusted estimates of hypertension were highest among legislators, senior officials and managers (71.5%; 95% CI, 41.9-101.0), followed by service and sales worker workers (44.7%; 95% CI, 41.2-48.2) and least among the professionals (37.1%; 95% CI, 27.1-47.2). Relative to never worked, legislators, senior officials and managers were twice more likely [adjusted OR (AOR) 2.00; 95% CI, 0.74-5.39] to be hypertensive, followed by plant and machine operators (AOR 1.33; 95% CI, 1.04-1.71). The odds of being hypertensive was least among those engaged in professional (engineering, health, education) activities. The other significant predictors are age, sex, residence, education level, household economic condition, family history of hypertension, chronic disease and depression.

CONCLUSION

The risk of hypertension varies with the types of work in which older Indians are engaged. Awareness and treatment of hypertension in high-risk occupation are recommended.

Risk factors of asthma in the Asian population: a systematic review and meta-analysis

Background and objective

An increasing trend of asthma prevalence was observed in Asia; however, contributions of environmental and host-related risk factors to the development of this disease remain uncertain. This study aimed to perform a systematic review and meta-analysis for asthma-associated risk factors reported in Asia.

Methods

We systematically searched three public databases (Web of Science, PubMed, and Scopus) in Feb 2021. We only included articles that reported environmental and host-related risk factors associated with asthma in the Asian population. Random-effect meta-analyses were conducted for frequently reported asthma-associated risk factors to provide an overall risk estimate of asthma development.

Results

Of 4030 records obtained from public databases, 289 articles were selected for review. The most frequently reported asthma-associated risk factor was the family history of allergy-related conditions. The random-effect asthma risk estimates (pooled odds ratio, OR) were 4.66 (95% confidence interval (CI): 3.73–5.82) for the family history of asthma, 3.50 (95% CI: 2.62–4.67) for the family history of atopy, 3.57 (95% CI: 3.03–4.22) for the family history of any allergic diseases, 1.96 (95% CI: 1.47–2.61) for the family history of allergic rhinitis, and 2.75 (95% CI: 1.12–6.76) for the family history of atopic dermatitis. For housing-related factors, including the presence of mold, mold spots, mold odor, cockroach, water damage, and incense burning, the random-effect pooled OR ranged from 1.43 to 1.73. Other risk factors with significant pooled OR for asthma development included male gender (1.30, 95% CI: 1.23–1.38), cigarette smoke exposure (1.44, 95% CI: 1.30–1.60), cigarette smoking (1.66, 95% CI: 1.44–1.90), body mass index (BMI)–related parameters (pooled OR ranged from 1.06 to 2.02), various types of air pollution (NO₂, PM10, and O₃; pooled OR ranged from 1.03 to 1.22), and pre- and perinatal factors (low birth weight, preterm birth, and cesarean section; pooled OR ranged from 1.14 to 1.32).

Conclusions

The family history of asthma was the most frequently reported risk factor for asthma development in Asia with the highest risk estimate for asthma development. This suggests a major role of the genetic component in asthma pathogenesis. Further study on asthma genetics is required to improve the current understanding of asthma etiology.

Understanding socio-economic inequalities in the prevalence of asthma in India: an evidence from national sample survey 2017-18

Background

Today, over 300 million people reside with asthma worldwide and India alone is home for 6% of children and 2% of adults suffering from this chronic disease. A common notion of disparity persists in terms of health outcomes across the poor and better-off section of the society. Thus, there is a need to explore socio-economic inequality in the contribution of various factors associated with asthma prevalence in India.

Methods

Data for the study were carved out from the 75th round of National Sample Survey (NSS), collected by the National Sample Survey Organization (NSSO) during 2017–18. The sample size for this study was 555,289 individuals, for which data was used for the analysis. Descriptive statistics were used to show the distribution of the study population. Further, bivariate and multivariate analysis was performed to identify the factors associated with Asthma prevalence. The concentration index was used to measure the inequality. Further, we used decomposition analysis to find the contribution of factors responsible for socio-economic status-related inequality in asthma prevalence.

Results

The prevalence of asthma was 2 per 1000 in the whole population; however, the prevalence differs by age groups in a significant manner. Age, sex, educational status, place of residence, cooking fuel, source of drinking water, household size and garbage disposal facility were significantly associated with asthma prevalence in India. It was found that asthma was more concentrated among individuals from higher socioeconomic status (concentration index: 0.15; p < 0.05). While exploring socio-economic inequality for asthma, richest wealth status (53.9%) was the most significant contributor in explaining the majority of the inequality followed by the urban place of residence (37.9%) and individual from age group 45–65 years (33.3%). Additionally, individual aged 65 years and above (27.9%) and household size less than four members (14.7%) contributed in explaining socio-economic inequality for asthma.

Conclusion

Due to the heterogeneous nature of asthma, associations between different socio-economic indicators and asthma can be complex and may point in different directions. Hence, considering the concentration of asthma prevalence in vulnerable populations and its long-term effect on general health, a comprehensive programme to tackle chronic respiratory diseases and asthma, in particular, is urgently needed.

Sex differences in prevalence and risk factors of hypertension in India: Evidence from the National Family Health Survey-4

To estimate sex-specific prevalence and associated socio-economic, demographic, and lifestyle risk factors of hypertension in India. We used data from the National Family Health Survey (NFHS-4) of 2015-16. The analysis based on 6,99,686 women (15-49 years) and 1,12,122 men (15-54 years) whose blood pressure (BP) were measured during the survey. Bivariate distribution was used to show the prevalence of hypertension and, maps were used to present its spatial patterns. Logistic regression model was used to identify sex-specific association between risk factors and hypertension. Results show that the overall prevalence of hypertension was 16.32% among men and 11.56% among women. We also found that the prevalence of hypertension across selected socio-economic, demographic and lifestyle background characteristics and in a majority of the states was higher among men compared to women. Odds ratios from logistic regression analysis direct sex-related differences in risk factors. Hypertension increases with an increase in age and the risk is higher among older women (AOR, 5.58; 95% CI, 5.16-6.03 for women aged 40-49 and AOR, 4.24; 95% CI, 3.94-4.57 for men aged 50-54) compared to men. Education, types of jobs (specially technical, administrative and managerial), marital status and non-vegetarian diet were significantly associated with hypertension in men. While other than age; non-working, consumption of alcohol, and being a diabetic was found to be major risk factors for this disease among women. There are sex-related differences in prevalence as well as risk factors of hypertension in India. In order to prevent early developments of hypertension, awareness related to changing lifestyles such as a diet rich in fruits, vegetables as well as screening to control BP should be promoted among youths and adults in India. The study also recommends sex-specific approaches in health infrastructure and policies besides increasing public awareness.

Relationship between cigarette smoking and blood pressure in adults in Nepal: A population-based cross-sectional study

Smoking and hypertension are two major risk factors for cardiovascular disease, the leading cause of death in Nepal. The relationship between cigarette smoking and blood pressure (BP) in Nepal is unclear. This study analysed the data from the 2016 Nepal Demographic and Health Survey to explore the differences in systolic BP (SBP) and diastolic BP (DBP) between current daily cigarette smokers and non-smokers in Nepali adults aged 18 to 49 years. A total of 5518 women and 3420 men with valid BP measurements were included. Age, body mass index, wealth quintile (socio-economic status) and agricultural occupation (proxy for physical activity) were included as potential confounders in multivariable linear regression analysis. Women smokers were found to have significantly lower SBP (mean difference 2.8 mm, 95% CI 0.7-4.8 mm) and DBP (mean difference 2.2 mm, 95% CI 0.9-3.6 mm) than non-smokers after adjustment. There were no significant differences in BP between smokers and non-smokers in males, either before or after adjustment. The lower BP in female cigarette smokers in Nepal may be explained by the physiological effect of daily cigarette smoking per se in women, or unmeasured confounders associated with a traditional lifestyle that may lower BP (for example, diet and physical activity). In this nationally representative survey, daily cigarette smoking was not associated with increased BP in males or females in Nepal.

Linkages between occupation and elevated blood pressure among men in India: a cross-sectional study

OBJECTIVES

The study aims to examine the linkages between occupation and elevated blood pressure among men aged 25-54 years in India.

METHODS

The study is based on the National Family Health Survey India, 2015-16. Age-standardized prevalence rates, χ² tests and multivariable ordered logistic regression models were used to fulfill the study objectives.

RESULTS

In India, more than five out of hundred men of age group 25-54 years are suffering from moderately or severely elevated blood pressure levels. The findings depict an occupation wise inequality in the elevated blood pressure levels. Men belonging to professional-managerial-technical (PR = 6.42 per 100 men) and sales (PR = 6.10 per 100 men) occupational groups are facing a much higher burden. From the fitted multivariable ordered logistic models, we found that highly educated-unemployed and married-unemployed men were found to be at higher risk of elevated blood pressure levels.

CONCLUSIONS

The study found linkages between the occupation of men and elevated blood pressure levels in India. Urgent attention is needed to the vulnerable occupational groups like professional-technical-managerial, clerical, and sales with a special focus to the unemployed cohort of the country.

Self-Reported Prevalence of Chronic Non-Communicable Diseases in Relation to Socioeconomic and Educational Factors in Colombia: A Community-Based Study in 11 Departments

Background:

Chronic non-communicable diseases are prevalent conditions in developing countries, such as Colombia. Several socioeconomic and educational factors have been associated with these pathologies. However, there is little country-specific information regarding the self-reported prevalence of chronic diseases and their association with the aforementioned factors in Colombia.

Objectives:

To evaluate the current situation of chronic non-transmissible diseases in Colombia by self-report and to analyze its potential relationship with sociodemographic, economic and educational factors.

Methods:

This is a cross-sectional baseline sub-analysis from the prospective, standardized collaborative PURE study in Colombia. Participants were recruited between 2005 to 2009, in 11 departments of the country, and included 7,485 subjects of 35 to 70 years old. Questionnaires of self-reported chronic non-communicable diseases, and demographic, socioeconomic and educational variables were applied.

Results:

Hypertension was the most prevalent chronic condition reported with a prevalence of 22.2% (21.2%–23.1%, 95% CI), followed by diabetes with a prevalence of 5.7% (5.1%–6.2%, 95% CI), asthma 2.7% (2.2%–3.0%, 95% CI), coronary heart disease 2.4% (2.0%–2.7%, 95% CI), stroke and heart failure 1.5% (1.2%–1.8%, 95% CI) each, chronic obstructive pulmonary disease 1.2% (0.6%–1.5%, 95% CI), and cancer 1.2% (1.0%–1.5%, 95% CI). Among the study sample, 23.3% (22.4%–24.3%, 95% CI) reported having one chronic NCDs, and 6.4% (5.9%–7.0%, 95% CI) reported having multiple chronic NCDs. The prevalence of multiple NCDs increased significantly with age, was more common in those from households with higher income, whereas it was significantly lower in persons with high education.

The central and central-east regions of the country are those with the higher prevalence of self-reported NCDs.

Conclusion:

The results of the current study indicate the presence of socioeconomic and educational inequalities in the distribution of chronic NCDs in the Colombian population.
