High prevalence of tobacco use, alcohol use and overweight in a rural population in Tamil Nadu, India

Exploring Behavioral Risk Factors for Non-communicable Diseases Among Undergraduate Medical Students in Western Gujarat: A Cross-Sectional Study

Background The burden of morbidity and death caused by non-communicable diseases (NCDs) such as cancer, diabetes, and cardiovascular disease is a significant global health concern influenced by modifiable behavioral risk factors. In India, the burden of NCDs is particularly high, with medical college students being a vulnerable population. This study aims to bridge the knowledge gap by investigating the prevalence and patterns of behavioral risk factors for NCDs among medical college students. Methodology A cross-sectional study was conducted on medical students in Gujarat. Risk factors for NCDs were assessed using various tools, including the General Health Questionnaire-12 (GHQ-12) for stress, the International Physical Activity Questionnaire-Short Form (IPAQ-SF) for physical activity, the Pittsburgh Sleep Quality Index (PSQI) for sleep quality, the body mass index (BMI) for obesity, and dietary factors. The chi-square test was employed as a statistical tool to determine the association between socio-demographic variables and various risk factors. A p-value of <0.05 was considered statistically significant. Results Among the 400 students surveyed, the prevalence of single behavioral NCD risk factors was as follows: 248 (62%) reported stress (GHQ-12), 215 (54%) experienced poor sleep quality (PSQI), 251 (63%) had low levels of physical activity (IPAQ), 339 (85%) had inadequate fruit and vegetable intake, 97 (24%) consumed extra salt during meals, 163 (41%) were overweight or obese, and 189 (47%) had three or more risk factors for NCDs. In bivariate logistic regression analysis, factors such as age, male gender, urban residence, hostel stay, and lower socioeconomic status were found to be statistically significant (p < 0.05). Conclusion This study reveals an alarming failure of medical colleges to positively influence students' health behaviors, despite their medical knowledge. The high rates of inactivity, stress, poor diet, and obesity among students demonstrate the curriculum's inability to instill preventative lifestyle practices. This omission in training compromises students' own health and their ability to counsel patients on NCD prevention. Urgent reform is needed to integrate health promotion into the curriculum, providing a supportive campus culture focused on wellness. By overlooking students' behaviors, medical colleges gravely disserve these future providers. This evidence compels curriculum reform to develop exemplary physician role models for NCD prevention.

Hazardous use of alcohol among men in the tribal population of Jawadhi Hills, Tamil Nadu: Nature, prevalence, and risk factors

Background:

Worldwide, hazardous use of alcohol is common among many cultures and societies and adversely impacts families and communities, with significant morbidity and mortality. Scheduled Tribes (STs) who are socially deprived and marginalised have higher rates of alcohol use.

Aim:

We attempted to determine the nature, prevalence, and risk factors associated with hazardous consumption of alcohol in the tribal community.

Methodology:

A cross-sectional study was conducted among adult male and permanent residents of Jawadhi hills. A total of 1200 men were interviewed. Study participants were chosen by Probability Proportionate to Size (PPS) sampling method. The questionnaire that documented socio-demographic characteristics and patterns of alcohol use was used. AUDIT tool was used to assess the hazardous use of Alcohol. Data were analysed using SPSS.

Results:

Majority of the men were middle-aged, married, and were from lower socio-economic strata. A large proportion of men (65%) had a history of alcohol consumption in the last one year using one-year, of whom a quarter showed hazardous use (29%) and another quarter exhibited alcohol dependency (24%). Tobacco use, higher income and local alcohol production were found to be significant risk factors for Hazardous alcohol use.

Conclusion:

Alcohol consumption needs to be treated as a social problem and has to be tackled at the policy level. Population-based interventions, legislation, taxation, policies regarding the manufacture and sale of alcohol, are some of the ways to address this problem.

Prevalence of Alcohol and Tobacco Use in India and Implications for COVID-19 - Niyantrita Madhumeha Bharata Study Projections

Abuse of legal substances in India includes alcohol and tobacco, which are the major risk factors for various non-communicable diseases and deaths. The current pandemic has identified tobacco consumption as a risk factor for COVID-19, highlighting the need to control substance abuse. The objective of this study was to estimate the prevalence of substance abuse in India and discuss the cost-effective public health strategies (such as yoga) to alleviate COVID-related anxiety in order to prevent substance abuse and its associated co-morbidities such as type 2 diabetes mellitus. This study reports the data on tobacco and alcohol abuse from a nationwide randomized two-arm diabetes control trial (Niyantrita Madhumeha Bharata, 2017) conducted by the Indian Yoga Association (IYA) through Swami Vivekananda Yoga Anusandhana Samsthana (S-VYASA), Bengaluru. Data of 30,354 participants who abuse tobacco and 30,159 participants who abuse alcohol were collected all over India. The prevalence is estimated at around 8.7% for alcohol abuse and 7.9% for tobacco abuse, Arunachal Pradesh state ranking the highest regarding both alcohol and tobacco abuse, while the Tripura state ranked the lowest. School and college-based mandatory yoga programs need to be implemented to prevent the increase of substance abuse in India to alleviate the psychosocial stress of adolescents and college-going students, besides the installation of the mindfulness-based diabetes yoga protocol (DYP) in the wellness centers of Ayushman Bharat.

Cross-shift change of acute kidney injury biomarkers in sugarcane farmers and cutters

Sugarcane farmers and cutters have been reported to be at high risk of acute kidney injury. This cross-sectional study aimed to assess acute kidney injury biomarkers, and cross-shift change among 150 sugarcane cutters and 98 sugarcane farmers in Thailand. Physical health examination, environmental measurements, and measured urinary neutrophil gelatinase-associated lipocalin (NGAL) were assessed. Cross-shift change of urine creatinine (uCr), albumin creatinine ratio (ACR), and NGAL between sugarcane farmers and cutters was compared. Factors influencing abnormal post-shift ACR and NGAL were analyzed by binary logistic regression adjusted with covariates. Sugarcane cutters were significantly more likely to take nonsteroidal anti-inflammatory drugs (NSAID) and herbs to relieve pain than sugarcane farmers. Males were more likely to be current smokers and drinkers although 62% of cutters and 56% of farmers were female. Sugarcane farmers and cutters had similar post-shift estimated glomerular filtration rate (eGFR) and ACR levels. Cross-shift measurements showed that both sugarcane cutters and sugarcane farmers had significantly higher post-shift geometric mean (GM) urinary NGAL, but that the cross-shift changes of NGAL were significantly higher for sugarcane cutters (182%) vs. sugarcane farmers (112%). Water intake less than recommendation of subjects was a significant predictor of a higher risk for an abnormal post-shift ACR after controlling for covariates, while being a sugarcane cutter was a predictor of a lower risk of an abnormal risk of a post-shift NGAL after controlling for covariates. Measurements of heat stress (WBGT plus workload) found that sugarcane cutters exceeded recommended exposures while sugarcane farmers were compliance to the TLV. These findings suggest that to protect sugarcane farmers and cutters, preventative measures are needed.

Prevalence and determinants of Alcohol use in a remote rural area in South India: A community-based cross-sectional study

Introduction:

Alcohol use is a major public health problem in India. We sought to study the use of alcohol and its risk factors in a rural area in South India.

Methods:

This study was conducted in 20 villages surrounding a Rural Health Training Centre, located in South India. The study was done from March 2018 to October 2018 with the help of Medical Interns and Medical Social Workers using a pretested questionnaire.

Results:

In a total population of 14,925, 11,995 individuals are in the age group of 15 years and above, among whom 1,005 were reported to be using alcohol. The prevalence of alcohol among 15 years and above is 8.4% (7.9–8.9) and the overall prevalence in the total population is 7% (6.3–7.1). Prevalence of alcohol use among males and females are 16% and 1%, respectively. The alcohol use is higher among those who prefer open defecation (adjusted Odds Ratio (aOR) 1.2 (1.0–1.4)), Kutcha house (aOR 1.7 (1.4–2.2)) or semi-pucca house (aOR 1.3 (1.121.6)), lower caste (Most Backward Castes (MBC) aOR 1.7 (1.2–2.2), Scheduled Castes (SC) aOR 2.1 (1.6–2.9)), male gender (aOR 41 (29–59)), Married 5.0 (3.7–6.8), or Separated 2.6 (1.5–4.4) and Diabetes 1.6 (1.1–2.3).

Conclusion:

Alcohol use in a remote rural area is high among socially deprived communities who live in kutcha and semi-pucca houses and belong to a lower caste. This needs serious public health interventions to improve their socioeconomic status.

Systematic review and meta-analysis of the prevalence of smokeless tobacco consumption among adults in Bangladesh, India and Myanmar

OBJECTIVE

To estimate the pooled prevalence of smokeless tobacco consumption (STC) by gender and location in Bangladesh, India and Myanmar and to identify periodic changes in STC prevalence using data extracted from published studies.

METHODS

We searched for a combination of keywords in electronic databases and used a standard form to extract data from each article. We undertook a meta-analysis to estimate pooled prevalence and confidence intervals within these countries. To compare periodic changes in STC prevalence, we grouped studies into five-year periods (2000-2004, 2005-2009, 2010-2014 and 2015-2019).

RESULTS

The pooled estimates of STC prevalence were 25% (95% CI: 22-28%), 22% (95% CI: 15-28%) and 21% (95% CI: 14-28%) for Bangladesh, India and Myanmar, respectively. In pooled estimates across these countries, we found higher STC prevalence for men (30%; 95% CI: 24-35%) than women (16%; 95% CI: 10-23%) and for rural dwellings (24%; 95% CI: 18-31%) than urban dwellings (17%; 95% CI: 10-24%). We found significant decrease in STC in Bangladesh and India in the period 2010-2014 and 2015-2019, respectively. In Myanmar, STC prevalence increased significantly and substantially in 2010-2014, to levels higher than in Bangladesh and India.

CONCLUSIONS

The prevalence of STC in Bangladesh, India and Myanmar is highest in rural areas and among men. Public health prevention strategies are needed to maintain decrease in STC in Bangladesh and India, and to reverse the increased use in Myanmar.

Socio-demographic patterning of the individual-level double burden of malnutrition in a rural population in South India: a cross-sectional study

BACKGROUND

The double burden of malnutrition is the co-occurrence of undernutrition (e.g. underweight, stunting, and micronutrient deficiencies) and over-nutrition (e.g. obesity, type 2 diabetes, and cardiovascular disease) at the population, household, or individual level. The objectives of this study were to determine the extent and determinants of individual-level co-morbid anemia and overweight and co-morbid anemia and diabetes in a population in rural Tamil Nadu, South India.

METHODS

We undertook a cross-sectional study of adults (n = 753) in a rural region of Tamil Nadu, South India. A survey assessed socio-demographic factors, physical activity levels, and dietary intake. Clinical measurements included body-mass index, an oral glucose tolerance test, and blood hemoglobin assessments. Multivariable logistic regression analyses were used to determine associations between risk factors and two co-morbid double burden pairings: (1) anemia and overweight, and (2) anemia and diabetes.

RESULTS

Prevalence of co-morbid anemia and overweight was 23.1% among women and 13.1% among men. Prevalence of co-morbid anemia and diabetes was 6.2% among women and 6.3% among men. The following variables were associated with co-morbid anemia and overweight in multivariable models [odds ratio (95% confidence interval)]: female sex [2.3 (1.4, 3.85)], high caste [3.2 (1.34, 7.49)], wealth index [1.1 (1.00, 1.12)], rurality (0.7 [0.56, 0.85]), tobacco consumption [0.6 (0.32, 0.96)], livestock ownership [0.5 (0.29, 0.89)], and energy-adjusted meat intake [1.8 (0.61, 0.94)]. The following variables were associated with co-morbid anemia and diabetes in multivariable models: age [1.1 (1.05, 1.11)], rurality [0.8 (0.57, 0.98)], and family history of diabetes [4.9 (1.86, 12.70).

CONCLUSION

This study determined the prevalence and factors associated with individual-level double burden of malnutrition. Women in rural regions of India may be particularly vulnerable to individual-level double burden of malnutrition and should be a target population for any nutrition interventions to address simultaneous over- and undernutrition.

Smoking and alcoholism among adult population and its association with outlet density in a hilly area of North India

Background

The rising burden of non-communicable diseases is a threat to India. The behavioural risk factors having largest contribution to NCDs. Neighbourhood retailing of tobacco products, and alcohol are important risk factors. The objectives of the present study were to determine the prevalence of smoking and alcoholism among adults of Srikot, Uttarakhand, and to determine its relationship with tobacco, and alcohol retail outlet density.

Materials and methods

The study design was a community based cross sectional study, which was done in Srikot, Uttarakhand among adults aged above 20 years, selected by systematic sampling. A semi-structured questionnaire was used. The outlet density was measured mapped using android application.

Results

A total of 155 were enrolled in the study of which 61.3% were females. A total of 11.6% of the study participants were smokers. On multivariate analysismale gender, and alcohol use was significantly associated with increased risk of smoking (p < 0.05). A total of 16.8% of the study participants were alcohol user. On multivariate analysis it was found male gender, and smoking was significantly associated with increased risk of alcohol use (p < 0.05). On mapping the study area, it was found that total tobacco selling outlets were 40. There was no alcohol-selling outlet in the study area.

Conclusion

The community is in an early stage of urbanization as evident from the burden of smoking, and alcohol use. This burden of smoking might be worsened by outlet density of tobacco seller.

Risk factors for cardiovascular disease in rural South India: cohort study

BACKGROUND AND OBJECTIVES

Cardiovascular diseases (CVD) accounted for one-third of the deaths in India. We conducted a cohort study to estimate the incidence of CVD and the association of established risk factors with the incident CVD in a rural population in South India.

DESIGN, SETTING AND PARTICIPANTS

We conducted a community-based cohort study among 6026 adults aged 25-64 years in five villages in Tiruvallur, Tamil Nadu. We did baseline (2005-2007) and two follow-up surveys in 2008-2009 and 2013-2015. Risk factors studied were tobacco, alcohol, hypertension, self-reported diabetes and central obesity.

OUTCOME MEASURES

Outcome measures were fatal or non-fatal ischaemic heart disease or cerebrovascular event. We estimated HRs for the risk factors and population attributable fraction (PAF).

RESULTS

We followed up 5641 (94.4%) subjects, and follow-up duration was 33 371 person years. The overall incidence of cardiovascular event or death was 4.6 per 1000 person years. Current smoking (HR 1.6, 95% CI 1.1 to 2.6) and hypertension (HR 2.2, 95% CI 1.5 to 3.4) were the risk factors among men and accounted for 47% of the PAF. Among women, hypertension (HR 1.8, 95% CI 1.0 to 3.4), self-reported diabetes (HR 4.3, 95% CI 2.2 to 8.1) and central obesity (HR 2.2, 95% CI 1.2 to 4.0) were associated with CVD and accounted for more than half of the PAF.

CONCLUSIONS

We described the high burden of fatal CVD and identified the role of CVD risk factors such as hypertension, self-reported diabetes, smoking and central obesity. There is an urgent need to implement low-cost interventions such as smoking cessation and treat hypertension and diabetes in primary care settings.

Asian BMI criteria are better than WHO criteria in predicting Hypertension: A cross-sectional study from rural India

BACKGROUND

International Obesity Task Force proposed lower body mass index (BMI) cut-off values for defining overweight and obesity in Asian population. However, there is an absence of unanimity regarding the definition of overweight and obesity that is confusing while estimating disease burden, resource allocation, and priority setting. Therefore, the primary aim of the study was to assess the prevalence of overweight and obesity and its predictors as per different criteria (WHO criteria, Modified Asian criteria of BMI classification and BF% estimation by bioelectric impedance analysis technique). The secondary aim was to assess the concordance of overweight and obesity as diagnosed using these three methods.

METHODOLOGY

A community-based cross-sectional study was conducted in a rural area of Rohtak, north India over a period of 1 year with a sample size of 1080. Anthropometric measurements including height, weight, blood pressure, body fat % analysis were recorded using standard protocols.

RESULTS

The prevalence of overweight and obesity were observed to be 49.62% (N = 536) as per the modified criteria for the Asian Indians (BMI ≥23 kg/m2) and 34.62% (N = 374) according to WHO criteria (BMI ≥25 kg/m2). A total of 18.3% of the study population were hypertensive. Modified criteria of BMI classification for Asian Indians had high sensitivity (67%) as compared to WHO criteria (55%) in predicting, diagnosing hypertension, and resembled sensitivity estimate obtained through direct body fat percentage estimation (69%).

CONCLUSION

Modified criteria of overweight and obesity classification are better in terms of reducing comorbid dysmetabolic conditions, as exemplified by hypertension.

Biological risk factors for coronary artery disease among adults residing in rural area of North Karnataka, India

BACKGROUND

Coronary artery disease (CAD) accounts for 60% of all deaths and 47% of burden of diseases which is progressively increasing in rural population in terms of absolute numbers. Biological risk factors contribute significantly to the cardiovascular burden. Hence, this study was undertaken to assess the biological risk factors among adults residing in rural area.

MATERIALS AND METHODS

A community-based cross-sectional study conducted among 980 adults aged between 20 and 60 years residing in rural area of Belagavi district, India. World Health Organization-STEPS-based predesigned questionnaire was used for data collection by house-to-house visit after obtaining written informed consent. Sociodemographic variables and biological risk factors which included hypertension, self-reported diabetes mellitus, overweight, and obesity were assessed. Statistical analysis was done using Pearson's Chi-square test and P value less than 0.05 was considered significant.

RESULTS

In the present study, 48.8% were men and 51.2% were women. Prevalence of hypertension was 26.6%, self-reported diabetes mellitus 6.3%, overweight 26.7%, and obesity was 7.0%. Men had higher prevalence of hypertension and overweight, whereas women had higher prevalence of diabetes and obesity. A significant gender difference was noted with the biological risk factors for CAD (P < 0.05). Advancing age, lesser education, and retirement from the job were the contributors for the increasing prevalence of these risk factors (P < 0.05); however, the socioeconomic status did not show any influence (P > 0.05).

CONCLUSION

Biological risk factors, which included hypertension, diabetes, and overweight, were observed in a significantly higher proportion among men, whereas women were more obese with a significant higher proportion. Advancing age, lesser education, and retirement from the job were the contributors for the increasing prevalence of these risk factors.

Olanzapine versus aprepitant for the prophylaxis of chemotherapy-induced nausea and vomiting in breast cancer patients receiving doxorubicin-cyclophosphamide regimen: A prospective, nonrandomized, open-label study

OBJECTIVE:

Despite the guideline-directed therapy, complete absence of nausea was noted only in 33% of breast cancer patients on anthracycline-cyclophosphamide regimen. Hence, we sought to compare the efficacy of aprepitant (APT) versus olanzapine (OLP) in preventing chemotherapy-induced nausea and vomiting (CINV) in breast cancer patients on doxorubicin-cyclophosphamide regimen.

PATIENTS AND METHODS:

A prospective, open-label, nonrandomized study was conducted at the Department of Oncology. Eighty-three patients completed the study with 43 in the APT group and 40 in OLP group. Data about nausea and vomiting were collected using Multinational Association of Supportive Care in Cancer Antiemesis Tool (MAT). The severity of nausea and vomiting was assessed by the MAT and Common Terminology Criteria for Adverse Events (CTCAE) version 4.03, respectively.

RESULTS:

Complete response (no emesis and no rescue medication) was achieved in 81% of the patients in APT group and 85% in the OLP group in the acute period (P = 0.661); 74% of patients in APT group and 85% in OLP group had no nausea during the same period (P = 0.233). Among the OLP patients who had nausea, 67% had moderately severe and 33% had Severe grade, and in the APT group, severity was equally distributed in mild, moderate, and severe grades. Among the patients who had vomiting, severe (CTCAE) vomiting was noticed in 81% of patients who were treated with APT compared to 50% in OLP group.

CONCLUSION:

OLP was found to be an equally effective alternative to APT in the antiemetic prophylaxis of CINV in breast cancer patients receiving chemotherapy with doxorubicin-cyclophosphamide regimen.

Epidemiology of smoking in the rural area of a medium-sized city in Southern Brazil

OBJECTIVE

To estimate the prevalence of smoking and associated factors among rural residents.

METHODS

This is a population-based, cross-sectional study of 1,519 individuals carried out in 2016. We randomly selected 24 of the 50 census tracts that make up the eight rural districts of the city of Pelotas, State of Rio Grande do Sul, Brazil. All individuals aged 18 years or more living in the randomly selected households were eligible. Smokers were all those who smoked ≥ 1 cigarette/day for at least one month or declared that they had stopped smoking for less than one month. The independent variables included socioeconomic, demographic, behavioral, and health characteristics. We investigated age of onset, duration of addiction, number of cigarettes smoked/day, pack-years, and types of cigarettes consumed. Poisson regression was performed to calculate the adjusted prevalence ratios (PR) and 95% confidence intervals (95%CI).

RESULTS

The prevalence of smoking was 16.6% (95%CI 13.6-20.0), and it was twice as high in men in relation to women (PR = 1.99, 95%CI 1.44-2.74), in socioeconomic class D or E in relation to class A or B (PR = 2.23, 95%CI 1.37-3.62), and in those who considered their health poor or very poor in relation those with good or very good health (PR = 2.02, 95%CI 1.33-3.08). It was also higher in persons aged 30-59 years (compared to those aged < 30 years), with 5-8 years of education level (compared to those with ≥ 9 years), and with positive screening for alcohol-related disorder. Prevalence was lower among individuals who were overweight or obese than in those with normal weight. Smoking began on average at 16.9 years, with an average consumption of approximately 14 cigarettes/day and mean pack-years of 22 packs/year. The paper hand-rolled cigarette was the most consumed (57.6%).

CONCLUSIONS

Approximately one in six adults in rural Pelotas is a current smoker. The findings show the existence of social inequalities related to smoking addiction. Actions to prevent and control smoking should continue to be stimulated, especially in the most vulnerable subgroups.

Alcohol consumption among tobacco farmers: prevalence and associated factors

RESULTS

This study aims to describe the prevalence of heavy drinking, high-risk alcohol consumption and associated factors among tobacco farmers. A cross-sectional study was carried out with 2,469 tobacco farmers over 18 years old in 2011. High-risk alcohol consumption was considered the intake of three or more standard doses per day for men or two or more for women. Heavy drinking was considered the intake of four or more standard doses per day for men and three or more for women. Hierarchical multivariate analysis was performed to investigate the association with socioeconomic, behavioral, and occupational variables. : The prevalence of high-risk and heavy drinking was of 4.7% and 1.09% among women and 30.8% and 4.8% among men, respectively. The factors associated with high-risk drinking for men and women were the percentage of income tobacco accounted for (PR 1.3 and 0.4), being an employee (PR 1.3 and 3.1), and use of pesticides (PR 1.5 and 2.1), respectively. Heavy drinking among men was associated with losing the crop (PR 1.6), attending religious activities (PR 0.3), and hours working in agriculture (PR 0.6). Occupational factors were associated wit high-risk alcohol consumption among men. The associated factors vary according to the pattern of consumption assessed.

Depression and Behavioral Problems Among Adolescent Girls and Young Women Employees of the Textile Industry in India

Stress and depression are common in textile industry employees due to inadequate working conditions and challenging socioeconomic conditions. The objective of the study was to assess depression and mental health among adolescent and young females currently employed in a textile factory located in Tamil Nadu compared with past employees and women who have never been employed. This cross-sectional study included a total of 107 participants in each study group who were interviewed. The Patient Health Questionnaire-9 and Strengths and Difficulties Questionnaire were administered to screen participants for depression and mental health. More current employees (16.82%) and past employees (15.88%) suffered from depression severe enough to require treatment compared with never employed girls and young women (2.8%). Of the study participants, 59.8% of current employees, 63.6% of past employees, and 32.7% of never employed women had mental health or behavior problems. In the regression model, history of abuse was significantly associated with depression. Participants who were current employees and reported family debt and a history of abuse were significantly more likely to have mental health or behavior problems. Mental health issues such as depression and behavior problems were more likely among adolescent girls currently employed in textile industries. Further studies into the causes of this phenomenon are needed.

Factors associated with glucose tolerance, pre-diabetes, and type 2 diabetes in a rural community of south India: a cross-sectional study

BACKGROUND

India's national rural prevalence of type 2 diabetes has quadrupled in the past 25 years. Despite the growing rural burden, few studies have examined putative risk factors and their relationship with glucose intolerance and diabetes in rural areas. We undertook a cross-sectional study to determine the prevalence of impaired fasting glucose (IFG), impaired glucose tolerance (IGT), and type 2 diabetes in a rural area of south India. In addition, we determined which factors were associated with type 2 diabetes.

METHODS

We sampled 2 % of the adult population from 17 villages using a randomized household-level sampling technique. Each participant undertook a questionnaire that included basic descriptive information and an assessment of socioeconomic status, physical activity, and dietary intake. Height, weight, waist and hip circumference, and blood pressure measurements were taken. An oral glucose tolerance test was used to determine diabetes status. We used stepwise logistic model building techniques to determine associations between several putative factors and type 2 diabetes.

RESULTS

753 participants were included in the study. The age- and sex-standardized prevalence of IFG was 3.9 %, IGT was 5.6 %, and type 2 diabetes was 10.8 %. Factors associated with type 2 diabetes after adjusting for confounders included physical activity [OR 0.81], rurality [OR 0.76], polyunsaturated fat intake [OR 0.94], body mass index [OR 1.85], waist to hip ratio [OR 1.62], and tobacco consumption [OR 2.82].

CONCLUSION

Our study contributes to the growing body of research suggesting that diabetes is a significant concern in rural south India. Associated risk factors should be considered as potential targets for reducing health burdens in India.

Factors associated with BMI, underweight, overweight, and obesity among adults in a population of rural south India: a cross-sectional study

BACKGROUND

Overweight, obesity, and related chronic diseases are becoming serious public health concerns in rural areas of India. Compounded with the existing issue of underweight, such concerns expose the double burden of disease and may put stress on rural healthcare. The purpose of this article was to present the prevalence and factors associated with underweight, overweight, and obesity in an area of rural south India.

METHODS

During 2013 and 2014, a random sample of adults aged 20-80 years were selected for participation in a cross-sectional study that collected information on diet (using a food frequency questionnaire), physical activity (using the Global Physical Activity Questionnaire), socioeconomic position (using a wealth index), rurality (using the MSU rurality index), education, and a variety of descriptive factors. BMI was measured using standard techniques. Using a multivariate linear regression analysis and multivariate logistic regression analyses, we examined associations between BMI, overweight, obesity, and underweight, and all potential risk factors included in the survey.

RESULTS

Age and sex-adjusted prevalence of overweight, obesity class I, and obesity class II were 14.9, 16.1, and 3.3 % respectively. Prevalence of underweight was 22.7 %. The following variables were associated with higher BMI and/or increased odds of overweight, obesity class I, and/or obesity class II: Low physical activity, high wealth index, no livestock, low animal fat consumption, high n-6 polyunsaturated fat consumption, television ownership, time spent watching television, low rurality index, and high caste. The following variables were associated with increased odds of underweight: low wealth index, high rurality index, and low intake of n-6 PUFAs.

CONCLUSION

Underweight, overweight, and obesity are prevalent in rural regions of southern India, indicating a village-level dual burden. A variety of variables are associated with these conditions, including physical activity, socioeconomic position, rurality, television use, and diet. To address the both underweight and obesity, policymakers must simultaneously focus on encouraging positive behaviour through education and addressing society-level risk factors that inhibit individuals from achieving optimal health.

The Prevalence and Determinants of Chronic Non-Communicable Disease Risk Factors amongst Adults in the Dikgale Health Demographic and Surveillance System (HDSS) Site, Limpopo Province of South Africa

BACKGROUND

The aim of the study was to determine the prevalence and determinants of chronic non-communicable disease (NCD) risk factors in a rural community in the Limpopo Province of South Africa.

METHODS

This survey was conducted using the WHO "STEPwise approach to the surveillance of non-communicable diseases" (STEPS) methodology. Participants were residents of the Dikgale HDSS site and standardised international protocols were used to measure behavioural risk factors (smoking, alcohol consumption, fruit and vegetable intake and, physical activity) and physical characteristics (weight, height, waist and hip circumferences and blood pressure-BP). Fasting blood glucose, triglyceride, cholesterol and HDL-C were determined in 732 participants. Data were analysed using STATA 12 for Windows.

RESULTS

The prevalence of current smokers amongst the participants was 13.7%, of which 81.3% were daily smokers. Alcohol was consumed by 16.3% of the participants. The majority of participants (88.6%) had low daily intake of fruit and vegetables and low physical activity (66.5%). The prevalence of hypertension amongst the participants was 38.2%. Overweight, obesity and high waist circumference were prevalent in females. The cardio-metabolic risk profile was not significantly different between men and women. People who were older than 40 years, overweight or obese and those who consumed alcohol were more likely to be hypertensive. Smoking was associated significantly with older age, males, never married and divorced people. Alcohol consumption was associated with older age, males, low educational status and low income.

CONCLUSION

High levels of risk factors for NCDs among adults in the Dikgale HDSS suggest an urgent need for health interventions to control these risk factors at the population level in order to reduce the prevalence of NCDs.

Global epidemiology of obesity, vegetarian dietary patterns, and noncommunicable disease in Asian Indians

An increase in noncommunicable disease (NCD) in India has been attributed to an epidemiologic transition whereby, due to urbanization, there is an increase in traditional cardiovascular disease risk factors such as obesity. Accumulated biomarker data on the "Asian Indian phenotype" identify central obesity, which occurs at a lower body mass index (BMI), as a particularly potent risk factor in Asian Indians. A revised WHO case definition for obesity in India [BMI (in kg/m(2)) >25] has identified an obesity epidemic that exceeds 30% in some cities and rivals that in Western nations. This review summarizes 2 key lines of evidence: 1) the emergence of an obesity epidemic in urban and rural India and its contribution to the NCD burden and 2) the role of a "nutrition transition" in decreasing the whole plant food content of diets in India and increasing risk of obesity and NCDs. We then present new epidemiologic evidence from Asian Indians enrolled in the Adventist Health Study 2 that raises the possibility of how specific whole plant foods (eg, nuts) in a vegetarian dietary pattern could potentially prevent obesity and NCDs in a target population of >1 billion persons.

Cardiometabolic risk profile of rural South Indians undergoing coronary interventions

BACKGROUND

According to projected estimates, India will bear 60% of the world's cardiovascular disease (CVD) burden by the year 2020. CVD mortality rates are high in South India compared with the rest of India.

OBJECTIVE

The objective of this study was to examine the prevalence of behavioural, biological and metabolic risk factors in different age groups of rural South Indians undergoing coronary interventions under a governmental health insurance scheme.

METHODS

This study includes 1294 patients who underwent coronary interventions. Age, gender and anthropometric measurements were recorded. History of hypertension, diabetes, smoking and family history of ischaemic heart disease was obtained from every subject. Physical activity was assessed using a General Practise physical activity questionnaire. Investigations like haemogram, blood urea, serum creatinine, fasting and postprandial blood glucose, lipid profile and echocardiography were carried out for all patients.

RESULTS

Hypertension was found in 65% patients, 32.38% had diabetes mellitus, 41.65% were smokers (current and former), 37.17% had dyslipidemia, 31.06% had body mass index more than 25 kg/m, 27.04% were physically active, 37% had left ventricular dysfunction, and 8.57% had renal impairment ( table 1). Statistically significant differences were seen in the prevalence rates of different risk factors in the compared age groups (p=<0.05) except for hypertension and dyslipidemia (p=0.596 and 0.306).

CONCLUSIONS

Risks to health, as an area of study, has recently begun to receive attention in developing countries including India. Population-based strategies aimed at bringing down risk factor levels in the community can translate into major public health benefits.

Prevalence, awareness, treatment, control and risk factors for hypertension in a rural population in South India

OBJECTIVES

Hypertension is a major public health problem with prevalence ranging 22-30% in urban India. There are few data on hypertension epidemiology in rural India. We conducted a survey to estimate prevalence, awareness, treatment, control and risk factors for hypertension in a rural population in south India.

METHODS

We did cross-sectional survey in 11 villages in Tamil Nadu. We collected data on behavioral risk factors, anthropometric and blood pressure measurements. We defined hypertension according to WHO criteria.

RESULTS

Study population included 10,463 subjects aged 25-64 years. Among them, 4,900 (46.8%) were males. Hypertension was present for 2,247 (21.4%) subjects and 1,682 (74.9%) among hypertensives were newly detected. Overall 20% were on treatment and 6.6% had blood pressure control. Age ≥35 years, BMI ≥ 23 kg/m(2) and central obesity were risk factors significantly associated with hypertension (p < 0.05). In addition, alcohol consumption, higher education level were risk factor among males and family history of hypertension was risk factor among females (p < 0.05).

CONCLUSION

Hypertension is an emerging challenge in rural India. We need health promotion programs and reorientation of primary health care to improve hypertension detection and management.
