Chronic pain and tobacco dependence are two highly prevalent and comorbid conditions. The rate of smoking among persons in pain may be greater than twice the rate observed in the general population. Smokers tend to experience more adverse pain-treatment outcomes than do nonsmokers, and there is mounting evidence to suggest that smokers with comorbid pain disorders may have more difficulty abstaining from tobacco. The main goal of the current study was to examine cross-sectional relations between chronic pain status and past use of pharmacotherapy for smoking cessation. We also tested associations between chronic pain status and frequency of past quit attempts. Data were derived from a nationally-representative survey of households in the continental United States. After adjusting for sociodemographic factors, substance use, mood and anxiety disorders, and number of attempts to quit smoking, smokers with chronic pain were found to be 1.67 times more likely to endorse past use of pharmacotherapy for smoking cessation, relative to smokers with no chronic pain. Chronic pain status was not associated with number of past attempts to quit smoking. These data suggest that smokers with chronic pain are motivated to quit smoking, and may be particularly amenable to pharmacologic intervention. Results are discussed with regard to clinical implications and directions for future research.

Current understanding of periodontal disease derives from studies mostly conducted in developed countries. However, the disease process among those studied populations may be confounded by the professional dental care. There have been few attempts to investigate factors related to the disease among populations of developing countries where the natural history of the disease is minimally confounded by care. This imbalance is evident in risk assessment research on the associations between periodontal disease and smoking-one of the most significant risk factors for the disease. Also, most studies on smoking used convenience or purposive samples, which may bias the findings. Therefore, there is a need for research conducted among a representative sample of a developing country. The present study aimed to describe the prevalence, extent and severity of chronic adult periodontitis among representative Vietnamese middle-aged adults. Also, it aimed to investigate smoking, which is highly prevalent in Vietnam, as a risk indicator for periodontal disease in a population with minimal access to dental care. The study was designed as a cross-sectional population-based study with a multistage, stratified random sample with probability of selection proportional to population size. The US National Institute of Dental Research (NIDR) protocol was used to assess loss of periodontal attachment among 575 dentate subjects in two randomly selected provinces. Assessment was made at mesial and buccal sites of every present tooth, excluding third molars. A parallel social survey collected socio-demographic information and smoking history, which were assessed for possible association with the disease status. Periodontal disease was highly prevalent among the sample. The patterns of the disease were similar to those reported from other populations. Virtually all subjects expressed some levels of disease, whereas only a few subjects or sites had severe disease. Bivariate analyses revealed significant associations between smoking and lower socio-economic status with more severe expression of the disease. Smoking was consistently associated with poorer periodontal status irrespective of outcome measure investigated. Multivariate models showed that smoking was the most predictive factor for the disease. The Odds Ratio of having severe periodontitis (that is, having 2+sites with loss of attachment more than or equal to 5 mm and 1+sites with pocket depth more than or equal to 4 mm) was 7.93 for heavy smokers compared to non-smokers. A dose-response effect of the association between smoking and the outcomes of the disease was also evident. The study provided a picture of the periodontal status of the representative sample from Vietnamese middle-aged adult population where the disease was less confounded by dental care. Furthermore, the study contributes consistency, strength and dose-response effect to the association of smoking as a risk indicator for periodontal destruction. The study should be used to assist the public health agencies in planning appropriate policies for Vietnam to address smoking and periodontal disease. / Thesis (M.Sc.)--Dental School, 2001.
