ABSTRACT To describe the prevalence of obesity, smoking, and both health risk factors together among adults in the United States.
Cross sectional analysis of a national health interview survey.
United States.
29 305 adults (aged > or = 18) in 2002.
Prevalence of adults who are obese (body mass index > or = 30), who smoke, and who are obese and smoke. Prevalence was stratified by age, sex, ethnic group, education, and income.
23.5% of adults were obese, 22.7% smoked, and 4.7% smoked and were obese.
Although the proportion of adults who smoke and are obese is relatively low, this subgroup is concentrated among lower socioeconomic groups.

    ABSTRACT: Objective To quantify the combined effect of maternal prepregnancy obesity and maternal gestational weight gain (GWG) on the shape of infant growth throughout the first year of life. Methods A retrospective cohort of mother–child dyads with children born between January 2007 and May 2012 was identified in a linked electronic medical record. Data were abstracted to define the primary exposures of maternal prepregnancy body mass index (BMI) and GWG, and the primary outcome of infant growth trajectory. Results We included 499 mother–child dyads. The average maternal age was 28.2 years; 55% of mothers were overweight or obese before pregnancy, and 42% of mothers had excess GWG, as defined by the Institute of Medicine. Maternal prepregnancy BMI (P < .001) and the interaction between prepregnancy BMI and maternal GWG (P = .02) showed significant association with infant growth trajectory through the first year of life after controlling for breast-feeding and other covariates, while GWG alone did not reach statistical significance (P = .38). Among infants of mothers with excess GWG, a prepregnancy BMI of 40 kg/m2 versus 25 kg/m2 resulted in a 13.6% (95% confidence interval 5.8, 21.5; P < .001) increase in 3-month infant weight/length percentile that persisted at 12 months (8.4%, 95% confidence interval 0.2, 16.5; P = .04). Conclusions The combined effect of excess maternal GWG and prepregnancy obesity resulted in higher infant birth weight, rapid weight gain in the first 3 months of life, with a sustained weight elevation throughout the first year of life. These findings highlight the importance of the preconception and prenatal periods for pediatric obesity prevention.

    ABSTRACT: Weight gain that commonly accompanies smoking cessation can undermine a person's attempt to quit and increase the risk for metabolic disorders. Research indicates that obese smokers have more weight concerns and gain more weight after quitting than non-obese smokers, yet little is known about possible reasons for these outcomes. We sought to gain an understanding of obese smokers' experiences of quitting and their attitudes and beliefs about the association between smoking and weight gain. In-depth semi-structured interviews were conducted with obese smokers who called a state tobacco quitline. Interviewers elicited discussion of obese smokers' thoughts about smoking, the effects of quitting on change in weight, challenges they faced with quitting, and how quitlines might better serve their needs. Participants (n = 29) discussed their fear of gaining weight after quitting, their beliefs about smoking and their weight and significant experiences related to quitting. Participants' awareness of weight gain associated with quitting was based on prior experience or observation of others who quit. Most viewed cessation as their primary goal and discussed other challenges as being more important than their weight, such as managing stress or coping with a chronic health condition. Although weight gain was viewed as less important than quitting, many talked about changes they had made to mitigate the anticipated weight gain. Weight gain is a concern for obese smokers interested in quitting. Understanding the relative importance of body weight and other challenges related to smoking cessation can help tailor interventions for the specific group of smokers who are obese and interested in smoking cessation.

    ABSTRACT: Objective: To compare the tobacco products use patterns of known diabetics and non diabetics. Material and Methods: A community-based cross-sectional study using STEPwise approach among adults using a multistage, stratified, cluster random sample. Data was collected using a questionnaire which included sociodemographics; tobacco products use habits, history of diabetes, biochemical and anthropometric measurements. Results: Of the total of 4654 subjects who participated in the study, 1016 (21.8%) were ever smoked tobacco products users and 65 (1.4%) were ever smokeless tobacco products users. Known Diabetes prevalence was 15.3% (712 known diabetics). There were no significant differences in diabetic status and smokeless tobacco products use for both ever and current use. For smoked products diabetics are fewer in current smokers and more in ex smokers. Diabetics started smoking significantly older, smoked for longer duration and higher intensity than non diabetics. Conclusion: Diabetes appears to be associated with smoked but not smokeless tobacco products use.
