OBJECTIVES: To investigate the relationship of specific nutrients and food items with oral precancerous lesions among tobacco users. DESIGN: A population-based case-control study. SETTING: Villages in Palitana taluk of Bhavnagar district, Gujarat, India. SUBJECTS AND METHODS: An interviewer-administered food frequency questionnaire, developed and validated for this population, was used to estimate nutrient intake in blinded, house-to-house interviews. Among 5018 male tobacco users, 318 were diag...

Objective: To test the effect of dietary nutrients on oral precancerous lesions in a reverse-smoking (i.e. smoking with the glowing end inside the mouth) population in South India. Design: Case‐control. Cases with precancerous lesions were matched to an equal number of lesion-free controls matched on age (^5 years), sex and village. All subjects used tobacco in some form. Dietary data were obtained using an intervieweradministered food-frequency questionnaire, designed for use in this population...

INTRODUCTION: Overall mortality rates are higher among cigarette smokers than non-smokers. However, very little is known about the health effects of other forms of tobacco use widely prevalent in India, such as bidi smoking and various forms of smokeless tobacco (e.g. chewing betel-quid). We therefore carried out a cohort study in the city of Mumbai, India, to estimate the relative risks for all-cause mortality among various kinds of tobacco users. METHODS: A baseline survey of all individuals a...

BACKGROUND Although tobacco is the primary etiologic factor for oral precancerous lesions in India, evidence from other sources indicates that diet may modify risk. This case–control study was designed to minimize a variety of biases in its attempt to investigate the relation between diet and oral precancerous lesions. METHODS In a house-to-house survey of 5056 tobacco users in a rural area of Ernakulam district in Kerala, India, 226 individuals (44 females and 182 males) were found to have prec...

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 81item 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 l-year period and the other at the end. FFQ and 24HR-derived nut...
