Association of exclusive smokeless tobacco consumption with hypertension in an adult male rural population of India

A Bayesian network for estimating hypertension risk due to occupational aluminum exposure

Background

The correlation between metals and hypertension, such as sodium, zinc, potassium, and magnesium, has been confirmed, while the relationship between aluminum and hypertension is not very clear. This study aimed to evaluate the correlation between plasma aluminum and hypertension in electrolytic aluminum workers by the Bayesian networks (BN).

Methods

In 2019, 476 male workers in an aluminum factory were investigated. The plasma aluminum concentration of workers was measured by inductively coupled plasma mass spectrometry. The influencing factors on the prevalence of hypertension were analyzed by the BN.

Results

The prevalence of hypertension was 23.9% in 476 male workers. The risk of hypertension from plasma aluminum in the Q2, Q3, and Q4 groups was 5.20 (1.90-14.25), 6.92 (2.51-19.08), and 7.33 (2.69-20.01), respectively, compared with that in the Q1 group. The risk of hypertension from the duration of exposure to aluminum of >10 years was 2.23 (1.09-4.57), compared without aluminum exposure. Area under the curve was 0.80 of plasma aluminum and the duration of exposure to aluminum was based on covariates, indicating that aluminum exposure had important predictive value in the prevalence of hypertension in the occupational population. The results of the study using the BN model showed that if the plasma aluminum of all participants was higher than Q4 (≥47.86 µg/L) and the participants were drinking, smoking, diabetes, central obesity, dyslipidemia, and aged >50 years, the proportion of hypertension was 71.2%.

Conclusions

The prevalence of hypertension increased significantly with the increase of plasma aluminum level.

Socioeconomic inequality among smoking and smokeless tobacco uses among males in India: a decomposition analysis

OBJECTIVE

India is the third-largest tobacco manufacturer and its use in India is characterised by a high prevalence of smoking and smokeless (sl) tobacco use. This results in 1 million deaths per year in the country. Given the high burden of tobacco use, this study examines the regional variations and socio-economic correlates of tobacco use in India.

METHODS

National Family Health Survey- 5 (2019-2020) have been analysed for the purpose of the study. A sample of 101,839 males aged 15-54 years was included in this study. Primary outcomes of tobacco use were categorised into smoking, smokeless and dual use of smoking and smokeless tobacco use. Bivariate analysis and decomposition analysis was done to study the socio-economic inequality.

RESULTS

The prevalence of tobacco use among males in India is around 41 percent. As indicated by the results of the logistics regression, age is positively related to smoking among males. Males aged 45-54 years are 2.5 (95 % concentration index [CI]:2.30-2.63) times probable to smoke, 1.4 (95% CI: 1.30-1.47) times probable of smokeless tobacco consumption and 2.2 (95% CI: 2.10-2.35) times more prone to using both types of substances compared to the younger age group. Males who are widower use smokeless 1.69 times (95% CI: 1.44-1.99) higher with reference to unmarried males. Males belonging to Scheduled tribes are 1.2 (95% CI: 1.13-1.25) times more likely to smoke, 1.3 (95% CI: 1.24-1.37) times more likely to use smokeless substances and 1.4 (95% CI: 1.33-1.47) times more likely to have dual use of tobacco than other social groups. Manual workers (both skilled are unskilled) are likely to smoke (odds ratio [OR] = 1.1, 95% CI: 1.02-1.11), use smokeless tobacco (OR = 1.3, 95% CI: 1.23-1.34) and have dual use of tobacco (OR = 1.29, 95% CI: 1.24-1.34) more than that of other categories. The decomposition of the concentration index shows a significant contribution from factors like a no education, ST/SC caste and wealth index. Among the states and union territories, the prevalence of tobacco is high in West Bengal, Tripura, Mizoram, Manipur, Meghalaya and Sikkim.

CONCLUSION

This study is useful for informing target-based prevention policies since it helps in highlighting regions, socio-economic and demographic groups especially vulnerable to tobacco addiction. In India, males from poorer and vulnerable socio-economic backgrounds are more likely to use tobacco. State wise, the eastern zone starting from West Bengal to the North-Eastern states have higher tobacco use than the rest of the country. There is an urgent need to frame policies for controlling the use of tobacco especially among high-risk groups.

Assessment of Risk Factors and the Relationship between Hypothyroidism with Hypertension in Diabetes Mellitus Patients: A Cross-Sectional Community-Based Study

(1) Background: hypertension (HTN) and diabetes mellitus (DM) represent two widely noncommunicable diseases that are prevalent globally, and they often correlate with chronic health issues. There has been an acknowledged connection between diabetes, hypertension, and hypothyroidism for quite some time. However, the extent of thyroid dysfunction among the diabetic population is not uniform and significantly differs across different research studies. This study was conducted with the objective of identifying the risk factors associated with hypothyroidism as well as assessing the relationship between hypothyroidism and hypertension in patients with diabetes. (2) Materials and Methods: Participants aged 18 years and above were included in this study, while pregnant women were excluded. Trained health professionals measured sociodemographic, behavioural, food practices, and anthropometric information about the participants. Each respondent sought medical advice regarding their health, and a face-to-face interview enabled them to express concern about the likelihood of being diagnosed with diabetes mellitus and hypertension. (3) Results: The study encompassed 640 participants, with an average age of 49.20 ± 13.0 years. Among these participants, 65.5% were female, and 34.5% were male. Of the total, 31.25% were diagnosed with diabetes mellitus, and 18.75% had hypertension. Interestingly, co-occurrence of both conditions was observed in 9.68% of the population. A comparison of thyroid function and indicators of blood sugar levels yielded consistent results across the different patient groups. Specifically, for diabetes mellitus (DM) patients, the average levels were 3.4 ± 9.8 pg/mL for fT3, 0.9 ± 0.7 ng/dL for fT4, 3.3 ± 6.2 μiU/mL for TSH, 153.1 ± 68.0 mg/dL for fasting plasma glucose (FPG), 213.2 ± 97.2 mg/dL for postprandial glucose (PPG), and 8.3 ± 3.2% for HbA1c. (4) Conclusion: It is concluded that patients with hypertension had a significant prevalence of diabetes mellitus. Subclinical hypothyroid subjects must be frequently screened for hypertension. Of 120 individuals with hypertension, 45 (37.5%) were also diagnosed with diabetes. This co-occurrence was significantly higher in subjects aged over 50 years (26.7%), in the lower socio-economic class (18.5%), and among those who were married (14.7%). Additionally, patients with hypertension exhibited a high prevalence of diabetes across different educational backgrounds and occupations, with the highest prevalence among postgraduates (37.5%) and professionals (24.0%), respectively. These findings highlight the need for an integrated approach to the management of hypertension and diabetes, particularly in high-risk demographics.

Predictors of hypertension among current smokeless tobacco users in India; analysis from the fourth round of National Family Health Survey (2015-2016)

Background

Hypertension is a major modifiable risk factor for cardiovascular and cerebrovascular diseases. The association between different risk factors including smoking and hypertension is studied extensively; however, there is a paucity of literature with respect to association between smokeless tobacco use and hypertension in India. In the current study, the relationship between smokeless forms of tobacco use and hypertension is being investigated.

Methodology

This study analyzed the data from fourth round of National Family Health Survey conducted during 2015-2016. Socio-demographic variables such as age, sex, education, wealth index, body mass index, smoked forms of tobacco use, and smokeless forms of tobacco like paan, gutkha, Khaini, etc., presence of co-morbidities were the independent variables. Hypertension was the dependent variable.

Results

It was observed from the present analysis that, smokeless tobacco use is a risk factor for hypertension both in the case of females OR-1.1**(1.08-1.13) as well as males OR-1.07**(1.03-1.1). The other predictors observed were overweight, consumption of alcohol, and diabetes.

Conclusion

It was concluded from the present study, that consumption of smokeless tobacco use acts as an independent risk factor for hypertension.

Interaction of multiple risk factors and population attributable fraction for type 2 diabetes and hypertension among adults aged 15-49 years in Northeast India

AIMS

The aim is to assess the association and population attributable fraction (PAF) of multiple risk factors combination for diabetes and hypertension among adults in the Northeast region of India.

METHODS

Data used is from the Indian Demographic Health Survey conducted in 2015-16. The study comprised 107, 766 respondents (95,153 females and 12, 613 males) aged 15-49 years. We examined four modifiable risk factors: smoking, alcohol consumption, aerated drinks consumption, and overweight or obesity. PAF was calculated using the relative risk from the multivariable logistic regression models.

RESULTS

Overweight or obesity in conjunction with smoking was associated with 43.9 % of patients with diabetes. Smoking in conjunction with alcohol and overweight or obesity contributed to 53% of patients with diabetes (PAF = 53 %). The three risk factors combination (i.e., smoking, alcohol, and overweight or obesity) is associated with the most hypertension cases (PAF = 50.7 %). Experiencing all four risk factors is associated with 50.3 % of patients with hypertension. In women, the four-risk combination contributed the most hypertension cases (PAF = 46.8 %).

CONCLUSIONS

Overweight or obesity was the single most significant factor leading to hypertension and diabetes among the study population. Also, smoking, alcohol, and overweight or obesity together are prominent risk factors for hypertension and diabetes.

Correlation between cotinine urinary levels & cardiovascular autonomic function tests among smokeless tobacco chewers: A cross-sectional study

Background & objectives:

Cardiovascular disease (CVD), the leading cause of death worldwide is responsible for over 17 million deaths globally, of which 10 per cent deaths have been expected due to consumption of tobacco. The association between CVD and chewing of tobacco is limited and remains arguable. The aim of this study was to find out the correlation between urinary cotinine level and cardiovascular autonomic function tests of tobacco chewers.

Methods:

In the present study, 600 participants, 300 smokeless tobacco chewers (STC) and 300 non-tobacco chewers (NTC), between 18 and 65 yr were selected. Various parameters such as anthropometric, systolic blood pressure (SBP), diastolic blood pressure (DBP), autonomic function tests and urinary cotinine levels were measured.

Results:

Significant difference (P<0.001) was noted in STC and NTC for anthropometric parameters, SBP, DBP and urinary cotinine levels. Sympathetic and parasympathetic autonomic function test showed significant difference on comparison in STC and NTC groups, except in Valsalva ratio. Correlations with urinary cotinine levels were significant for sympathetic autonomic functions, SBP fall (r=0.138, P=0.016), DBP rise (r=−0.141, P≤0.014); parasympathetic autonomic function, heart rate (HR) response to standing (r=−0.208, P≤0.003), deep breathing (r=−0.473, P≤0.001) and Valsalva ratio (r=−0.396, P≤0.0001).

Interpretation & conclusions:

Correlation between urinary cotinine levels and autonomic function tests elucidates the linkage involving autonomic nervous system damage which can be considered as an important associated relationship for early diagnosis of CVD health risk factors among smokeless tobacco (ST) users.

Tobacco Use and Risk Factors for Hypertensive Individuals in Kenya

This study aimed to examine the association between hypertension and tobacco use as well as other known hypertensive risk factors (BMI, waist–hip ratio, alcohol consumption, physical activity, and socio-economic factors among adults) in Kenya. The study utilized the 2015 Kenya STEPs survey (adults aged 18–69) and investigated the association between tobacco use and hypertension. Descriptive statistics, correlation, frequencies, and regression (linear and logistic) analyses were used to execute the statistical analysis. The study results indicate a high prevalence of hypertension in association with certain risk factors—body mass index (BMI), alcohol, waist–hip ratio (WHR), and tobacco use—that were higher in males than females among the hypertensive group. Moreover, the findings noted an exceptionally low awareness level of hypertension in the general population. BMI, age, WHR, and alcohol use were prevalent risks of all three outcomes: hypertension, systolic blood pressure, and diastolic blood pressure. Healthcare authorities and policymakers can employ these findings to lower the burden of hypertension by developing health promotion and intervention policies.

Relationship between chewing tobacco, smoking, consuming alcohol and cognitive impairment among older adults in India: a cross-sectional study

BACKGROUND

Physical aging increases the sensitivity to the effects of substance use, elevating the risk for cognitive impairment among older adults. Since studies on the association of substance use with cognitive ability in later years are scant in India, we aimed to explore the factors associated with cognitive impairment especially, alcohol consumption, smoking, and chewing tobacco later in life.

METHODS

The present research used nationally representative data from Building a Knowledge Base on Population Aging in India (BKPAI) that was conducted in 2011, across seven states of India (N=9,453). Sample distribution along with percentage distribution was calculated for cognitive impairment over explanatory variables. For finding the association between cognitive impairment over explanatory variables, binary logistic regression models were estimated.

RESULTS

About 16.5 percent of older adults in rural areas consumed smoked tobacco compared to 11.7 percent in urban areas. Nearly, 23.7 percent of rural older adults consumed smokeless tobacco in comparison to 16 percent in urban areas. Alcohol consumption was high among rural residents (7.9%) than urban counterparts (6.7%). The prevalence of cognitive impairment was 62.8% and 58% among older adults from rural and urban areas respectively. Older adults who smoked tobacco had a 24 percent significantly higher likelihood to have cognitive impairment with reference to older adults who did not smoke [OR: 1.24, CI: 1.02-1.49]. Moreover, older adults who consumed alcohol had a 30 percent significantly higher likelihood to have cognitive impairment [OR: 1.02, 1.65]. It was also found that older adults who had smoked along with consuming alcohol were at risk of worse cognitive outcomes than those who neither smoke nor drink alcohol [OR: 1.56, CI: 1.21-2.00] or consumed either of them unlike consuming smokeless tobacco only.

CONCLUSION

The encouragement of older people to stop smoking and smokeless tobacco use could be considered as part of a strategy to reduce the incidence of cognitive impairment. Further, appropriate measures should be taken for the detection of early stages of cognitive decline in older individuals and efforts should be made to improve the availability and quality of care for dementing older adults.

Socio-demographic and modifiable risk factors of diabetes and hypertension among resource constrained patients from rural areas in Mdantsane Township in South Africa

Background

Recently, developing countries have shown a dramatic increase in non-communicable diseases (NCDs). The burden of NCDs in South Africa has increased over the past years resulting in an estimated 37% of all- cause mortality and 16% of disability-adjusted life years. Currently, diabetes mellitus (DM) and hypertension (HTN) are the two most prevalent NCDs associated with the rapid increase in mortality.

Objective

To demonstrate the socio-demographic and modifiable risk factors of diabetes mellitus (DM) and hypertension (HTN) among South African adults.

Methods

A cross-sectional analytical study was conducted in the Cecilia Makiwane Hospital serving the residents of Mdantsane. Relevant socio-demographic data, anthropometric measurements, triplicate blood pressure, fasting blood glucose and lipogram analysis were obtained from 265 outpatients.

Results

Multivariate anlysis shows that; salt intake, smoking, elevated triglycerides and decreased high-density lipoprotein levels were significantly associated with DM with adjusted odds ratio of 0.18 (p=0.002), 0.26 (p=0.048), 2.19 (p=0.006) and 0.38 (p=0.001), respectively. Overweight and obesity were significantly associated with hypertension with odds ratio of 0.03 (p=0.01) and 0.06 (p=0.006), respectively.

Conclusion

The burden of DM and HTN on society can be drastically reduced with simple lifestyle changes, development of preventative strategies, large-scale screening and better disease management in South Africa.

Correlation of urinary cotinine with cardiovascular risk factors in pan masala tobacco users

BACKGROUND

Tobacco consumption is considered as one of the major risk factors for cardiovascular (CV) morbidity. However, the effect of paan masala tobacco (PMT) (a type of smokeless tobacco) consumption has not been well studied in our context. Our study is aimed to find an association of CV risk factors between PMT users and nonusers and to correlate those parameters with urinary cotinine level, a degradation product of nicotine occurring in tobacco.

METHODS

This comparative cross-sectional study was carried out among 200 participants. The effect of PMT use on CV risk factors such as blood pressure (BP), lipid profile, and body mass index was measured against urine cotinine level. Statistical tests used were χ2 test for categorical variable, independent t-test, Mann-Whitney U test, and Spearman's correlation applied for numerical variable, and multivariate regression analysis was performed as required. The level of significance was set at p < 0.05.

RESULT

Mean BP, total cholesterol, triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), and median cotinine level were found to be significantly higher in PMT users than in controls (p < 0.001). Urinary cotinine level was positively correlated with mean BP, TC, TG, and LDL-C in PMT users (p < 0.001). Similarly, the odds of having hypercholesterolemia and increased diastolic BP was also significantly higher in PMT users (p < 0.001).

CONCLUSION

PMT use has an adverse effect on CV risk parameters and there is a rational of cotinine measurement for screening CV risk among PMT users.

Smokeless tobacco and public health in Bangladesh

Despite the high prevalence of smokeless tobacco (SLT) use among adults in Bangladesh, SLT was not included in the Tobacco Control Law till 2013. Information on SLT use among Bangladeshi people is inadequate for policymaking and implementing effective control measures. With the aim to identify the prevalence and trends of different SLT products, health and economic impacts, manufacture, and sale of and policies related to SLT in Bangladesh, we carried out a literature review, which involved literature search, data extraction, and synthesis. Evidence suggests that in Bangladesh, SLTs range from unprocessed to processed or manufactured products including Sada Pata, Zarda, Gul, and Khoinee. Over 27% of Bangladeshi adults aged 15 years and older use SLT in one form or other. SLT use is associated with age, sex, education, and socioeconomic status. SLT consumption has reportedly been associated with increased prevalence of heart diseases, stroke, and oral cancer and led to around 320,000 disability adjusted life years lost in Bangladesh in 2010. No cessation service is available for SLT users in public facilities. Compared to cigarettes, taxation on SLT remains low in Bangladesh. The amendment made in Tobacco Control Law in 2013 requires graphic health warnings to cover 50% of SLT packaging, ban on advertisement of SLT products, and restriction to sale to minors. However, implementation of the law is weak. As the use of SLT is culturally accepted in Bangladesh, culturally appropriate public awareness program is required to curb SLT use along with increased tax and cessation services.

A systematic review on association between smokeless tobacco & cardiovascular diseases

BACKGROUND & OBJECTIVES

The association of smokeless tobacco (SLT) with cardiovascular diseases has remained controversial due to conflicting reports from various countries. Earlier meta-analyses have shown significantly higher risk of fatal myocardial infarction and stroke in SLT users. However, the risk of hypertension (HTN) with SLT products has not been reviewed earlier. This systematic review was undertaken to summarize the evidence available from global literature on the association of SLT with cardiovascular outcomes - heart disease, stroke and HTN.

METHODS

A systematic literature search was performed in PubMed and Google Scholar since their inception till October 2017 using pre-decided search terms and inclusion/exclusion criteria. Data were extracted from studies included independently by two authors and reviewed.

RESULTS

The review included 50 studies - 23 on heart disease, 14 on stroke and 14 on HTN. Majority of the studies evaluating heart disease or stroke were conducted in the European Region and most of these did not find a significant association between SLT use and either of these outcomes. On the other hand, 70 per cent of the studies on HTN were reported from South-East Asian Region and about half of the studies found a higher risk of HTN in SLT users.

INTERPRETATION & CONCLUSIONS

Current available evidence is insufficient to conclusively support the association of cardiovascular diseases with SLT use due to variability in results and methodological constraints in most of the studies. Region and product-specific well-designed studies are required to provide this evidence to the policymakers. However, advice on cessation of SLT products should be offered to patients presenting with cardiovascular diseases.

The Risk of Hypertension and Other Chronic Diseases: Comparing Smokeless Tobacco with Smoking

BACKGROUND

In the past, studies have compared smokeless tobacco and non-tobacco users for the risk of various chronic diseases. The differences in the risk of chronic diseases between smokeless tobacco user and smokers have not been explored. The objective of this study is to estimate the risk of chronic diseases among smokeless tobacco users compared to smokers.

METHODS

The data were used from the Study on Global Ageing and Adult Health (SAGE) Wave-1, conducted in 2007-2008 in India. The study sample is the respondents who reported consuming any form of tobacco in last 1 month. The total sample size was 4,038 respondents. The odds ratio of chronic morbidities was estimated taking smokers as the reference category.

RESULTS

The odds ratios for (self-reported) diabetes, asthma, and hypertension were not significant for smokeless tobacco user compared to smoked tobacco users. The odds ratio of chronic lung diseases (CLDs) was significantly lower among smokeless tobacco users compared to smoked tobacco users. The odds ratio of hypertension (measured) combined with low education and belonging to lowest wealth quintiles were not significant for smokeless tobacco users compared to smoked tobacco users. Duration of the use of smokeless tobacco and quantity of use was found to have no significant relation with risk of chronic diseases as compared to smoking.

CONCLUSION

This study did not find the significantly higher risk of chronic morbidities except for CLD for smokeless tobacco users compared to smoked tobacco users. The study suggests that the use of any form of tobacco may have a similar risk of chronic diseases.

Social epidemiology of hypertension in Buffalo City Metropolitan Municipality (BCMM): cross-sectional study of determinants of prevalence, awareness, treatment and control among South African adults

OBJECTIVES

This study examined hypertension prevalence, awareness, treatment and control and their determinants among adults attending health facilities in Buffalo City Metropolitan Municipality (BCMM) in the Eastern Cape.

DESIGN

A cross-sectional analytical study.

SETTINGS

The three largest outpatient clinics in BCMM.

PARTICIPANTS

Ambulatory adults (aged 18 years and over) attending the study settings during the study period (n=998).

PRIMARY OUTCOME MEASURE

The prevalence of hypertension (systolic blood pressure (BP) of ≥140 mm Hg and/or a diastolic BP of ≥90 mm Hg or current medication for hypertension), the awareness of it (prior diagnosis of it) and its treatment and control (Eighth Joint National Committee Criteria of BP <140/90/90 mm Hg).

SECONDARY OUTCOME MEASURE

Associated factors of hypertension, hypertension unawareness and uncontrolled hypertension.

RESULTS

Of the 998 participants included, the prevalence of hypertension was 49.2%. Hypertension unawareness was reported by 152 participants (23.1%) with significant gender difference (p=0.005). Male sex, age <45 years, higher level of education, single status, current employment, higher monthly income, current smoking, alcohol usage, absence of diabetes and non-obese were significantly associated (p<0.05) with hypertension unawareness.Of the participants who were aware of having hypertension (n=339), nearly all (91.7%, n=311) were on antihypertensive medication and only 121 participants (38.9%) achieved the BP treatment target. In the multivariate logistic regression model analysis, ageing (95% CI 1.9 to 4.4), being married (95% CI 1.0 to 2.0), male sex (95% CI 1.2 to 2.3), concomitant diabetes (95% CI 1.9 to 3.9), lower monthly income (95% CI 1.2 to 2.2), being unemployed (95% CI 1.0 to 1.9) and central obesity (95% CI 1.5 to 2.8) were the significant and independent determinants of prevalent hypertension.

CONCLUSION

The prevalence and awareness of hypertension was high in the study population. In addition, the suboptimal control of BP among treated individuals, as well as the significant cardiovascular risk factors, warrant the attention of health authorities of BCMM and the country.

Burden of Hypertension in the Capital of Afghanistan: A Cross-Sectional Study in Kabul City, 2015

Background. This study had the objective to assess the prevalence and associated factors of hypertension in an urban setting, Kabul city, Afghanistan. Materials and Methods. The World Health Organization's STEP-wise approach was adopted and used in Kabul in November 2015. The study analyzed a sample of 1172 adults in the age group of 25–70 years. Demographic, socioeconomic, and behavior data were collected using a structured questionnaire. Fasting venous blood sample was collected to assess the lipid profile and fasting blood sugar. Results. The study showed that the prevalence of hypertension among adult Kabul citizens was 32.3%. From this figure, 599 (51.1%) were females and 573 (48.9%) males with a mean age of 38.6 ± 12.2 years. Illiteracy rate was 49.6% and 77.5% were married. Smoking in adults were 8.1% and mouth snuff users were 9.8%. More than half (57.6%) of the study respondents were overweight and obese and 9.1% were recorded having raised blood sugar. In the multivariate logistic regression analysis, age, general obesity, central obesity, smoking, moderate physical activity, and taking fruits 3 days or less weekly were statistically significant predictors of hypertension. Conclusions. Burden of hypertension is increasing in main urban settings in Afghanistan. Integrated intervention focusing in main modifiable risk factors is needed to detect and prevent hypertension.

Prevalence of Hypertension and Determination of Its Risk Factors in Rural Delhi

Introduction. Hypertension is an important public health challenge in both economically developing and developed countries. It is one of the risk factors for cardiovascular mortality. Data is available on hypertension in urban population but few studies are reported in rural areas. Materials and Methods. It was a community based cross-sectional study conducted in two rural areas in Delhi among 1005 subjects selected using systematic random sampling method. WHO STEPS approach was used to collect data. Blood pressure, body mass index, and blood sugar were measured. Data analysis was done using SPSS version 16. Odds of hypertension among subjects with risk factors were calculated. p value less than 0.05 was considered significant. Results. The prevalence of hypertension was 14.1% among study subjects. Hypertension was significantly higher in individuals more than 35 years than those less than 35 years. Hypertension was significantly higher in those who take alcohol and in subjects with raised total cholesterol level but in multivariate analysis only age, education, and cholesterol levels were independently associated with hypertension. Conclusion. There is significant burden of hypertension in rural areas in Delhi. Age, education, and cholesterol levels were independent risk factors of hypertension.

Association of hypoadiponectemia with smokeless/dipping tobacco use in young men

BACKGROUND

Low levels of adiponectin, an adipocytokine with anti-diabetic, antiatherogenic and cardioprotective properties, is associated with increased risk of coronary disease in young men. Previous studies have demonstrated that smokeless tobacco is linked with a reduction of plasma adiponectin levels. However, the influence of smokeless tobacco (dipping tobacco) on plasma adiponectin levels still remains unknown. This study was conducted to assess the plasma adiponectin levels in young men who were using dipping tobacco.

METHODS

This was a community based study, which consisted of 186 young lean healthy males aged 20 to 35 years. Among these, 96 men were dipping tobacco users (BMI = 23.07 ± 2.68) and 90 were non-dipping tobacco users (BMI = 23.67 ± 1.46). Serum adiponectin levels were assessed by Enzyme Linked ImmunoSorbent Assay (ELISA).

RESULTS

A statistically significant difference in the mean adiponectin level between tobacco dipper and non-dipper groups was observed (p = 0.0001). A significant difference between the two groups was also observed in baseline parameters including triglyceride and random blood sugar levels (p < 0.05). However, no significant difference was observed between the two groups in other clinical parameters.

CONCLUSIONS

Findings of this study suggest that dipping tobacco use was significantly associated with low level of adiponetin in community dwelling young males. This emphasizes the importance of developing community intervention to reduce the use of dipping tobacco, which will reduce the tobacco associated disease burden in the community and will improve public health.

Missed opportunities for brief intervention in tobacco control in primary care: patients' perspectives from primary health care settings in India

BACKGROUND

World Health Organization has called for tobacco cessation to be integrated into primary care. Primary Health Centres (PHC) offer opportunities for tobacco-use screening and brief cessation advice but data on such activities in developing countries such as India are limited. The aim of this study was to investigate screening and brief intervention practices of health service providers in primary care.

METHODS

This cross-sectional study was conducted in 2012 among 1,549 patients aged over 18 years visiting PHCs in 12 districts of two Indian states- Andhra Pradesh and Gujarat. Responses were collected using an interviewer-administered questionnaire. Information was obtained on participants' tobacco use status, reason(s) for seeking medical care, whether participants had been screened for and advised to quit tobacco use. The primary outcome was whether patients were screened during their visit to the PHC. Data analysis was performed using multi-level logistic regression.

RESULTS

Less than one-third (447) of patients were screened for tobacco use during their visit to the PHC. People presenting with respiratory complaints were 84% more likely (OR: 1.84; 95% CI: 1.30 to 2.62) to be screened for tobacco use when compared to those with general ailments. Number of quit attempts in the past 12 months was strongly associated with the outcome of being screened for tobacco use, indicating that people who had more than 5 quit attempts were two times more likely to be screened for tobacco use than those who had never attempted to quit tobacco (OR: 1.99; 95% CI: 1.03 to 3.8). Among the 447 patients who were screened for tobacco use, only 136 reported to have been counselled and merely 67 patients received suggestions on ways to quit tobacco.

CONCLUSION

Our results show that opportunities for screening and providing tobacco use cessation advice were largely missed by the health service providers. Our study suggests that there is an urgent need to incorporate tobacco cessation interventions as part of standard practice so that all patients are given an opportunity to be asked about their tobacco use and to be given advice and counselling to quit tobacco.

Prevalence of hypertension and associated cardiovascular risk factors in Central India

OBJECTIVES

To study the difference in the prevalence of hypertension and associated risk factors in urban and rural populations and the association of hypertension with various determinants.

MATERIALS AND METHODS

A community-based cross-sectional study was conducted in 48 villages and 15 urban wards of Jabalpur District of Central India. Nine hundred and thirty-nine individuals aged 20 years and above (624 from rural areas and 315 from urban areas) were included in the study. The prevalence of hypertension and associated cardiovascular risk factors was assessed in the urban and rural populations. A pretested questionnaire was used to collect data on socio-demographic, behavioral, and dietary factors. Anthropometric measurements of weight, height, waist and hip circumference, and blood pressure measurements were taken using the standard methodology. The glucose oxidase-peroxidase and cholesterol oxidase-cholesterol peroxidase methods were used to measure plasma glucose and serum cholesterol, respectively. Bivariate analysis was followed by multivariate analysis to detect the odds of getting hypertension with various risk factors for the urban and rural populations separately. Hypertension was defined as per Joint National Committee (JNC) - VII criteria.

RESULTS

The response rate was 97%. Overall prevalence of hypertension was 17%, with 21.4% in the urban population and 14.8% in the rural population. Significantly higher mean values of weight, height, body mass index (BMI), hip circumference (HC), waist circumference (WC), waist hip ratio (WHR), systolic blood pressure (SBP), fasting blood sugar (FBS), and serum cholesterol levels were mapped in the urban population in comparison with the rural population. Multivariate logistic regression analysis identified increasing age, parental history of hypertension, tobacco smoking, tobacco chewing, physical inactivity, high estimated per capita salt consumption, and BMI ≥27.5 kg/m(2) as independent predictors for hypertension in the urban population, while in the rural population, increasing age, physical inactivity, central obesity, tobacco chewing and tobacco smoking were independent predictors for hypertension.

CONCLUSION

The prevalence of hypertension and other cardiovascular risk factors was high in both urban and rural communities. Therefore, there is a need for comprehensive health promotion programs to encourage lifestyle modification.

Smokeless tobacco use: a risk factor for hyperhomocysteinemia in a Pakistani population

Background

Smokeless tobacco (ST) use is highly prevalent in the South Asian populations. While there have been a number of reports on association of ST consumption with cancer, very few studies have been conducted to investigate its relationship with cardiovascular disease. Hyperhomocysteinemia is a well-recognized risk factor for cardiovascular disease; however, its association with ST use has never been investigated. The objective of this study was to evaluate the relationship of ST use with hyperhomocysteinemia in an urban Pakistani population.

Methodology/Principal Findings

In a cross-sectional study for assessment of risks of hyperhomocysteinemia, 872 healthy adults (355 males and 517 females of age range 18–60 years) were recruited from a low-income population in Karachi, Pakistan. A detailed questionnaire was administered which included information about smoking, non-smoking, use of ST alone (chewing as well as sniffing) and use of ST with betel nuts. Fasting serum/plasma levels of homocysteine, folate, vitamin B12 and pyridoxal phosphate (PLP; a coenzymic form of vitamin B6) were analyzed. In this population, 43.4% males and 15.5% females were found to be regular users of ST products. Laborers and vendors were the major ST consumers. Smoking was not found to be associated with plasma/serum concentrations of homocysteine, folate, vitamin B12 and PLP. However, homocysteine concentrations in the group which consumed ST alone and the group which consumed ST along with betel nut were significantly higher compared to the non-user group (17.7±7.5 µmol/L, 25.48 µmol/L vs. 11.95 µmol/L, respectively; p<0.01). Odds ratio for the association of hyperhomocysteinemia (>15 µmol/L) was 11-fold higher in the ST-consumer group compared to the non-user group, [OR (95%CI)  = 11.34 (7.58–16.96); p<0.001], when the model was adjusted for age, gender, folate and vitamin B12 status.

Conclusion

This study shows a positive association between ST consumption and hyperhomocysteinemia in a low-income urban Pakistani population.

Prevalence of cardiovascular risk factors among rural population of elderly in Wardha district

BACKGROUND

Cardiovascular diseases (CVD) are a leading cause of mortality among adults in India, and their risk factors (tobacco, hypertension, diabetes, overweight, and obesity) are common. Most risk-factor surveys have focused on young and middle aged adults. We measured the prevalence of risk factors for CVD among elderly (age 60 years or more) in rural India.

METHODS AND RESULTS

In a door-to-door cross-sectional survey we did a non-laboratory based assessment of risk factors (smoking or tobacco use in any form, diabetes mellitus, either known or newly detected hypertension, abnormal waist-hip-ratio, or a high body mass index) among elderly living in 23 villages in rural central India. Laboratory based assessment of risk factors was done in those who had two or more of the five measured conventional risk factors. We compared the distribution of risk factors between men and women. Among 2424 elderly included in the study (51% women, mean age 67), the prevalence of smokeless tobacco use was 50.8% (95% CI 48.1-52.8; smoking 10.5% (95% CI 9.3-11.8); and hypertension46.3% (95% CI 44.3-48.4). Only 10.2% participants were previously known to have had hypertension, and remaining 36.1% were detected to be hypertensive during the survey. A total of 8.2%(95% CI 7.0-9.5) participants were overweight and 4.1% (95% CI 3.3-4.9) had central obesity. The prevalence of dyslipidemia in those who underwent blood based tests was 40.6% (95% CI 36.5-44.9); and hyperglycemia 4.9% (95% CI 3.2-7.1).

CONCLUSIONS

Strategies to reduce the risk of cardiovascular disorders among elderly should be focused on reducing tobacco use and early detection and optimal control of hypertension.

Tobacco and metabolic syndrome

Tobacco is a leading contributor to morbidity and mortality globally. Metabolic syndrome is a constellation of abdominal obesity, atherogenic dyslipidemia, raised blood pressure, insulin resistance (with and without glucose intolerance), pro-inflammatory state, and pro-thrombotic state. Tobacco use is associated with various core components of metabolic syndrome. It has been found to play a causal role in various pathways leading on to development this condition, the current article discusses various facets of this association.

Missed opportunities for tobacco use screening and brief cessation advice in South African primary health care: a cross-sectional study

BACKGROUND

Primary health care (PHC) settings offer opportunities for tobacco use screening and brief cessation advice, but data on such activities in South Africa are limited. The aim of this study was to determine the extent to which participants were screened for and advised against tobacco use during consultations.

METHODS

This cross-sectional study involved 500 participants, 18 years and older, attended by doctors or PHC nurses. Using an exit-interview questionnaire, information was obtained on participants' tobacco use status, reason(s) for seeking medical care, whether participants had been screened for and advised about their tobacco use and patients' level of comfort about being asked about and advised to quit tobacco use. Main outcome measures included patients' self-reports on having been screened and advised about tobacco use during their current clinic visit and/or any other visit within the last year. Data analysis included the use of chi-square statistics, t-tests and multiple logistic regression analysis.

RESULTS

Of the 500 participants, 14.9% were current smokers and 12.1% were smokeless tobacco users. Only 12.9% of the participants were screened for tobacco use during their current visit, indicating the vast majority were not screened. Among the 134 tobacco users, 11.9% reported being advised against tobacco use during the current visit and 35.1% during any other visit within the last year. Of the participants not screened, 88% indicated they would be 'very comfortable' with being screened. A pregnancy-related clinic visit was the single most significant predictor for being screened during the current clinic visit (OR = 4.59; 95%CI = 2.13-9.88).

CONCLUSION

Opportunities for tobacco use screening and brief cessation advice were largely missed by clinicians. Incorporating tobacco use status into the clinical vital signs as is done for pregnant patients during antenatal care visits in South Africa has the potential to improve tobacco use screening rates and subsequent cessation.
