Concept: Habits


The hygiene hypothesis suggests that early-life exposure to microbial organisms reduces the risk of developing allergies. Thumb-sucking and nail-biting are common childhood habits that may increase microbial exposures. We tested the hypothesis that children who suck their thumbs or bite their nails have a lower risk of developing atopy, asthma, and hay fever in a population-based birth cohort followed to adulthood.

Smoking impairs endothelial function as an acute effect. However, few population-based studies have examined the association between smoking status and endothelial function or the dose-response and duration-response association of smoking with endothelial function. We examined whether smoking habits were associated with impaired endothelial function depending on smoking dose and duration.

To disentangle an association between tobacco smoking, smoking habits and pharmacokinetic patterns such as plasma concentrations of risperidone (RIS), its active metabolite 9-hydroxyrisperidone (9-OH-RIS) and the active moiety, AM, (RIS+9-OH-RIS) in a naturalistic sample.

Smoking may worsen the disease outcomes in patients with Crohn’s disease (CD), however the effect of exposure to second-hand cigarette smoke during childhood is unclear. In South Africa, no such literature exists. The aim of this study was to investigate whether disease phenotype, at time of diagnosis of CD, was associated with exposure to second-hand cigarette during childhood and active cigarette smoking habits.

The purpose of the study was to investigate the long-term associations between smoking habits, environmental tobacco smoke exposure (ETS), carotid intima-media thickness (IMT) progression rate, and rate of lumen diameter reduction in the carotid artery during a 16-year follow-up. Another objective was to investigate if an effect of smoking on progression rate could be explained by increased low grade inflammation.

Aim: To assess the overall prevalence of betel quid, areca nut, tobacco and alcohol use in the rural population of Muradnagar tehsil of Ghaziabad district and their awareness level towards adverse effects of these habits on general as well as oral health. Methods: A total of 422 persons from 63 households of four (4) villages were enrolled for the participation in the study. A preformed, pretested questionnaire was used to collect the information on prevalence of risk behaviours of chewing tobacco, areca nut, betel quid, smoking and alcohol consumption. Results: 72.5% of respondents reported indulgence in one or more habits of chewing areca nut, betel quid, tobacco, smoking and alcohol consumption. Smoking tobacco was the most common type of adverse habit in males while chewing tobacco in females. 26% of respondents believed that the community residents would quit the habit only if they personally experience any health problem due to the habit. Conclusion: In spite of being aware of risk of having multiple health problems, a major proportion of respondents were using betel quid, areca nut, tobacco and alcohol.

Tobacco is a leading cause of death worldwide, and nearly 80% of all smokers live in low to middle income countries. Previous research has suggested that smoking rates vary by occupation, with relatively low rates commonly seen among educators. Despite this fact, little is known about the smoking habits of teachers in Botswana. The objective of this study, therefore, was to investigate prevalence and correlates of tobacco use among school teachers in Botswana.
