Prevalence of risk factors of non-communicable diseases in Kerala, India: results of a cross-sectional study.

OBJECTIVE: To estimate the prevalence of non-communicable disease (NCD) risk factors in Kerala. DESIGN: A community-based, cross-sectional survey. PARTICIPANTS: In 2016-2017 a multistage, cluster sample of 12 012 (aged 18-69 years) participants from all 14 districts of Kerala were studied. MAIN OUTCOME MEASURES: NCD risk factors as stipulated in the WHO's approach to NCD risk factors surveillance were studied. Parameters that were studied included physical activity score, anthropometry, blood pressure (BP), and fasting blood glucose (FBG) and morning urine sample to estimate dietary intake of salt. RESULTS: The mean age was 42.5 years (SD=14.8). Abdominal obesity was higher in women (72.6%; 95% CI 70.7 to 74.5) compared with men (39.1%; 95% CI 36.6 to 41.7), and also higher among urban (67.4%; 95% CI 65.0 to 69.7) compared with rural (58.6%; 95% CI 56.6 to 60.5) residents. Current use of tobacco and alcohol in men was 20.3% (95% CI 18.6 to 22.1) and 28.9% (95% CI 26.5 to 31.4), respectively. The estimated daily salt intake was 6.7 g/day. The overall prevalence of raised BP was 30.4% (95% CI 29.1 to 31.7) and raised FBG was 19.2% (95% CI 18.1 to 20.3). Raised BP was higher in men (34.6%; 95% CI 32.6 to 36.7) compared with women (28%; 95% CI 26.4 to 29.4), but was not different between urban (33.1%; 95% CI 31.3 to 34.9) and rural (29.8%; 95% CI 28.3 to 31.3) residents. Only 12.4% of individuals with hypertension and 15.3% of individuals with diabetes were found to have these conditions under control. Only 13.8% of urban and 18.4% of rural residents did not have any of the seven NCD risk factors studied. CONCLUSION: Majority of the participants had more than one NCD risk factor. There was no rural-urban difference in terms of raised BP or raised FBG prevalence in Kerala. The higher rates of NCD risk factors and lower rates of hypertension and diabetes control call for concerted primary and secondary prevention strategies to address the future burden of NCDs.

Developing a smoke free homes initiative in Kerala, India.

BACKGROUND: Results of the Global Adult Tobacco Survey in Kerala, India found that 42 % of adults were exposed to second hand smoke (SHS) inside the home. Formative research carried out in rural Kerala suggests that exposure may be much higher. Numerous studies have called for research and intervention on SHS exposure among women and children as an important component of maternal and child health activities. METHODS: Community-based participatory research was carried out in Kerala. First, a survey was conducted to assess prevalence of SHS exposure in households. Next, a proof of concept study was conducted to develop and test the feasibility of a community-wide smoke free homes initiative. Educational materials were developed and pretested in focus groups. After feasibility was established, pilot studies were implemented in two other communities. Post intervention, surveys were conducted as a means of assessing changes in community support. RESULTS: At baseline, between 70 and 80 % of male smokers regularly smoked inside the home. Over 80 % of women had asked their husband not to do so. Most women felt powerless to change their husband's behavior. When women were asked about supporting a smoke free homes intervention, 88 % expressed support for the idea, but many expressed doubt that their husbands would comply. Educational meetings were held to discuss the harms of second hand smoke. Community leaders signed a declaration that their community was part of the smoke free homes initiative. Six months post intervention a survey was conducted in these communities; between 34 and 59 % of men who smoked no longer smoked in their home. CONCLUSIONS: The smoke free homes initiative is based on the principle of collective efficacy. Recognizing the difficulty for individual women to effect change in their household, the movement establishes a smoke free community mandate. Based on evaluation data from two pilot studies, we can project that between a 30 and 60 % reduction of smoking in the home may be achieved, the effect size determined by how well the smoke free home steps are implemented, the characteristics of the community, and the motivation of community level facilitators.

Smokeless tobacco use among patients with tuberculosis in Karnataka: the need for cessation services.

BACKGROUND: India is home to the largest population of patients with tuberculosis and tobacco users in the world. Smokeless tobacco use exceeds smoking and is increasing. There is no study to date that reports smokeless tobacco use before and after the diagnosis and treatment of tuberculosis. We assessed smokeless tobacco use among former patients of tuberculosis in Karnataka, India. METHODS: We conducted a community-based, cross sectional study among 202 men, who had been diagnosed and treated for tuberculosis (mean age 48 years), selected by multistage, random sampling. Using a semi-structured interview schedule, retrospective smoking and smokeless tobacco use were captured at eight time-points before and after the diagnosis and treatment of tuberculosis. RESULTS: Most patients suspended tobacco use during treatment. A high 44% prevalence of smokeless tobacco use 6 months before diagnosis was reduced to just 8% during the intensive phase of treatment and climbed to 27% 6 months after treatment. The tobacco use relapse rate 6 months after completion of treatment was higher for smokeless tobacco use (52%, 95% CI 41%-62%) than for smoking (36%, 95% CI 26%-45%). We also found that many patients who were advised to quit smoking continued using smokeless tobacco after completion of treatment. Additionally, new smokeless tobacco use was documented. Of the 11 new exclusive smokeless tobacco users, 10 shifted from smoking to smokeless tobacco use as a form of harm reduction. CONCLUSION: Patients with tuberculosis are advised by their doctors, at the time of diagnosis, to quit smoking. Several patients shift from smoking to smokeless tobacco use, which needs to be addressed while providing tobacco cessation services.

Doctors' behaviour & skills for tobacco cessation in Kerala.

BACKGROUND & OBJECTIVE: Several studies have shown that health professionals' advice for tobacco cessation to tobacco users enhances quit rate. Little is known about doctor's present tobacco cessation efforts in India. We examined doctors' reported inquiry into patient's use of tobacco and assessed their perceived need for training in tobacco cessation. METHODS: A cross-sectional survey was conducted in Kerala to collect information on doctor's practices, skills and perceived need for training in tobacco cessation. Pre-tested structured questionnaires were distributed in person to 432 male and 89 female doctors, of whom 264 male and 75 female doctors responded. RESULTS: One third of all the doctors surveyed reported that they always ask patients about tobacco use, three fourths advise all patients routinely to quit irrespective of the smoking status of patients and one tenth offered useful information on how to quit. About 15 per cent reported they received information from medical representatives, 32 per cent reported they had sufficient training and 80 per cent expressed interest in receiving training to help smokers quit. Majority of all doctors surveyed most commonly asked and advised patients to quit tobacco when patients had lung, heart, mouth disease or cancer. INTERPRETATION & CONCLUSION: Our results suggested that squalene may counteract the increase in body fat, BP and levels of plasma leptin, glucose, cholesterol and triglycerides. These effects of squalene may be further explored as a likely new approach for clinical management of high BP and obesity.

Smoking among tuberculosis patients in Kerala, India: proactive cessation efforts are urgently needed.

OBJECTIVES: To document smoking patterns among tuberculosis (TB) patients at eight different points of time before, during and after treatment, and to investigate the frequency and content of the quit smoking messages they received. DESIGN: A stratified random sample of 215 male TB patients from Kerala, India, who had completed treatment in the previous 9 months was surveyed using a pre-tested semi-structured interview schedule. RESULTS: Six months prior to diagnosis, 94.4% of male TB patients were ever smokers and 71.2% were current smokers. Although 87% of patients had quit smoking soon after diagnosis, 36% had relapsed by 6 months post treatment. One third relapsed during the first 3 months of treatment and another third during the next 3 months of treatment. Two thirds of all smokers received cessation advice from primary care physicians, but less than half received advice from others. Less than half of all messages were TB-specific; the rest were very general short instructions. Smoking more than 15 cigarettes/bidis at the time of diagnosis was significantly associated with a lower quit rate during treatment (OR 8.0, 95%CI 2.1-30.9). CONCLUSION: Messages to not smoke often go unheeded among TB patients. Proactive efforts are needed to encourage health staff and DOTS providers to give strong cessation messages.

Tobacco use among medical professionals in Kerala, India: the need for enhanced tobacco cessation and control efforts.

In developing nations where reductions in tobacco use have not been realized, it is critical that health professionals be encouraged to abstain from tobacco use. Data on tobacco use among health professionals in India are limited. We conducted cross-sectional surveys among 110 male medical school faculty (MSF), 229 physicians (67% male), 1130 medical students (46% male), and 73 female nursing students. Information on tobacco use and quit attempts was collected using structured questionnaires. Among the male respondents, current smokers were 15.1% of MSF, 13.1% of physicians, and 14.1% of medical students. Among current smokers, 42% of MSF and physicians and 51% of medical students had not attempted quitting in the last year. However, one third of MSF and physicians and 16% of medical students had attempted to quit at least 4 times. This is one of the first studies among health care professionals in India. Our findings show that a substantial proportion of physicians and medical students in Kerala continue to smoke. Smoking cessation programs are warranted in medical schools in Kerala. An initiative is presently underway by the authors to incorporate tobacco education into the medical school curriculum.

Tobacco use in Kerala: findings from three recent studies.

BACKGROUND: We reviewed the literature on tobacco use in Kerala and present data from three recently conducted unpublished studies. METHODS: Three cross-sectional studies were conducted; a community-based study of 1,298 individuals aged 15 years and above (mean age 37.4 years, men 630), a school-based study of 1,323 boys (mean age 14.7 years), and a college-based study of 1,254 male students (mean age 18.2 years). Information on tobacco use and sociodemographic variables was collected using pre-tested, structured interview schedules and questionnaires. RESULTS: In the community study, 72% of men and 6% of women had ever used tobacco. Compared to men with > 12 years of schooling, those with < 5 years of schooling were 7 times more likely to smoke (OR 7, CI 3.2-15.6). The age at initiation of smoking was 19 years among those < 25 years of age compared to 25.5 years among ever smokers > 44 years. In the school study, the age at initiation among boys aged < or = 1 3 years was 10.7 years compared with 13.2 years among > or = 16-year-old boys. Boys whose fathers and friends used tobacco were 2 times and 2.9 times more likely to use tobacco (OR 2.0, CI 1.3-3.1 and OR 2.9, CI 1.6-5.1), respectively, compared with their counterparts. In the college study, 29% of the commerce students used tobacco compared with 5.3% of polytechnic students (p < 0.001). CONCLUSION: Survey data suggest that the age at initiation of tobacco use appears to be falling. A series of cross-sectional studies with larger sample sizes of the youth is required to confirm this impression. Tobacco use habits of fathers and peers are significant influences on youth smoking. There is a need to focus on particular types of colleges as these appear to have high-risk tobacco use environments.
