INTERVENTION STUDY FOR PRIMARY PREVENTION OF ORAL CANCER AMONG 36 000 INDIAN TOBACCO USERS

In a house-to-house survey, 36 471 tobacco chewers and smokers were selected from the rural population in three areas of India. These individuals were interviewed for their tobacco habits and examined for the presence of oral leukoplakia and other precancerous lesions, first in a baseline survey, and then annually over a 5-year period. By personal advice and via the mass media they were encouraged to give up their tobacco habits. The follow-up rate was 97%. The control cohort was provided by the first 5-year results from a 10-year follow-up study conducted earlier in the same areas with the same methodology but on different individuals without any educational intervention. In Ernakulam district (Kerala) and Srikakulam district (Andhra) substantially more people stopped their tobacco habit and reduced the frequency of tobacco use in the intervention cohort than in the control cohort; in Bhavnagar district (Gujarat) the intervention group showed only a slightly higher proportion stopping their tobacco habits and no difference in the proportion reducing them. The 5-year age-adjusted incidence rate of leukoplakia in Ernakulam district was 11.4 in the intervention group versus 47.8 among men, and 5.8 versus 33.0 among women; and for palatal lesions in Srikakulam district the corresponding figures were 59.8 versus 260.8 among men and 289.5 versus 489.5 among women. In Bhavnagar the incidence rate of leukoplakia did not differ between the cohorts. Since most oral cancers are preceded by precancerous lesions, education on tobacco habits should be a feasible and effective approach to primary prevention of oral cancer.

Development and testing of a quantitative food frequency questionnaire for use in Kerala, India

OBJECTIVE To develop and test a food frequency questionnaire (FFQ) for use in rural areas of Kerala, India. DESIGN Based on food use and market surveys of the study area, a quantitative 81-item interviewer-administered FFQ was developed. A validation study was conducted consisting of 24-h diet recalls (24HR) administered on 8 days randomly selected over an entire year and two administrations of the FFQ, one at the beginning of the 1-year period and the other at the end. FFQ and 24HR-derived nutrient scores were compared using correlation and regression analyses and by examining differences in the nutrient scores. SETTING Rural villages in Ernakulum district, Kerala, South India. SUBJECTS In each of 30 households, the male head of household and female food preparer were enrolled. RESULTS Pearson (parametric) correlation coefficients (r(p)) averaged about 0.50 in comparing nutrient scores derived from the 24HR with those from the first FFQ and about 0.55 in comparing the second FFQ. On average, Spearman correlation coefficients (r(s)) were slightly lower than the r(p) in comparing the scores derived from the first FFQ, but virtually identical for the second FFQ. Regression analyses indicated better agreement in the comparison of the 24HR-derived scores with the first FFQ than the second FFQ. Difference scores, however, tended to be larger in comparing the first FFQ scores with the 24HR. CONCLUSIONS This FFQ produces results broadly comparable to those used in Europe and North America, indicating its suitability for comparing exposures within a study population in reference to health-related endpoints.

Effects of a tobacco control intervention for teachers in India: results of the Bihar school teachers study.

OBJECTIVES We assessed a school-based intervention designed to promote tobacco control among teachers in the Indian state of Bihar. METHODS We used a cluster-randomized design to test the intervention, which comprised educational efforts, tobacco control policies, and cessation support and was tailored to the local social context. In 2009 to 2011, we randomly selected 72 schools from participating school districts and randomly assigned them in blocks (rural or urban) to intervention or delayed-intervention control conditions. RESULTS Immediately after the intervention, the 30-day quit rate was 50% in the intervention and 15% in the control group (P = .001). At the 9-month postintervention survey, the adjusted 6-month quit rate was 19% in the intervention and 7% in the control group (P = .06). Among teachers employed for the entire academic year of the intervention, the adjusted 6-month abstinence rates were 20% and 5%, respectively, for the intervention and control groups (P = .04). CONCLUSIONS These findings demonstrate the potent impact of an intervention that took advantage of social resources among teachers, who can serve as role models for tobacco control in their communities.

Pictorial warnings on tobacco products at the point of sale in India

Training lay interventionists to support tobacco cessation among teachers in India

BACKGROUND The use of smokeless tobacco (SLT) is very common in India and leads to well established adverse health effects, particularly oral cancers. AIM To understand the perceptions of SLT users and health care providers regarding the prevalence of SLT in the community, awareness about its adverse effects and challenges for cessation METHODS: Key Informant (KI) interviews with SLT users; Focus group discussions (FGDs) with female and male tobacco users and health care providers RESULTS: KI perceptions among users and service providers were more or less similar regarding the extent of SLT use in the community. There was inadequate knowledge of the harm from SLT use, both among SLT users and health care providers. FGDs revealed high positive expectancies from SLT use and low risk perception. Shift from one to the other form of tobacco and a very early age of initiation, particularly among women, was observed. There was a low demand for assistance to quit. CONCLUSIONS SLT cessation efforts in the country must take cognizance of user perspectives and focus on strategies for demand reduction in all populations, including adolescents. Health care providers need to be trained in SLT cessation.

Improvement in prevalence of tobacco use among teachers in Bihar after COTPA.

Despite the rapidly increasing burden of tobacco-related morbidity and mortality in low- and middle-income countries, tobacco control initiatives – especially cessation – receive little emphasis. This is true despite low-cost methods that have potential for widespread dissemination. The purpose of this paper is to provide a case study example of how lay interventionists may be trained and supported to facilitate tobacco use cessation, based on the successful Tobacco-Free Teachers–Tobacco-Free Society program (TFT–TFS) implemented in Bihar, India. This school-based program included multiple components, with lay interventionists having a crucial role. The lay interventionists included health educators and lead teachers, both of whom were selected based on formative research, underwent extensive training and received continuing support. We emphasized encouraging and supporting teachers to quit tobacco use and engaging both tobacco users and nonusers to create a supportive environment for cessation. We also stressed that neither the health educators nor lead teachers were being trained as counselors or as cessation experts. We focused on the importance of respecting teachers as individuals and identifying locally relevant methods of cessation. Although we cannot isolate the precise contribution of the lay interventionists to the successful TFT–TFS intervention, the abstinence findings in favor of the intervention at follow-up are highly encouraging. Teachers have been neglected as lay interventionists for tobacco cessation despite the fact that they tend to be highly respected and credible. The approach used for TFT–TFS could be disseminable in multiple low- and middle-income country contexts through train-the-trainer programs targeted to teachers.

Primary prevention trial of oral cancer in India: a 10–year follow-up study

CONTEXT A high prevalence of tobacco use, even among educated professionals like teachers, has been reported from Bihar. After passing of the Cigarette and Other Tobacco Products Act (COTPA) in 2003, there have been major improvements in tobacco control nationwide. AIMS To compare tobacco use prevalence among school teachers in Bihar reported in 2000 with a survey in 2008 and investigate correlates of current and past tobacco-use. METHODS Data from the baseline survey of a cluster random sample of 72 government schools conducted during the beginning of two consecutive school years was analyzed. RESULTS The prevalence of current tobacco use was 35.5% and past use, 11.3%. Likelihood of current use compared with no use increased with age (odds ratio [OR] =3.27 for > 50 years compared to < 30, 95% confidence interval [CI]: [1.50, 7.13]); whereas that of past use compared to current use decreased (OR = 0.25, 95% CI: [0.09-0.68] for age > 50 years compared to < 30 years). DISCUSSION Compared to the tobacco use prevalence among Bihar school teachers reported from a survey in the year 2000 (77.4%), the prevalence in this survey in 2008 was much lower and past use, much higher. In the earlier survey, lal dantmajan was counted as a tobacco product. If we do the same in the current survey, and consider ever use, the prevalence even then was 53.9%, lower than the earlier figure. Although the tobacco use among teachers in Bihar is still high, it has decreased after the implementation of COTPA and the cessation has increased.
