Age of Smoking Initiation in Relation to Multiple Health Risk Factors among US Adult Smokers: National Health Interview Survey (NHIS) Data (2006-2018)

The adverse effects of multiple health risk factors have been well-documented; however, still understudied are the effects of early smoking in the context of multiple health risk factors. This study aimed to examine the role of early smoking initiation in relation to several health risk factors, including heavy drinking, physical inactivity, and obesity in later life among ever smokers in the USA. The National Health Interview Survey (NHIS) data from 2006 through 2018 were analyzed. The primary dependent variables were presence of three other risk factors: heavy drinking, physical inactivity, and obesity. The independent variable was the age of smoking initiation. Logit regression models were constructed to evaluate the association between smoking initiation and multiple health risk factors. All analyses were done in 2022. Among US adult smokers, 18.2% started smoking before age 15 (early initiators), 55.9% at ages 15-18 (middle initiators), and 25.9% at age 20 or later (late initiators). Compared to late smoking initiators, the odds of engaging in additional health risk factors increased by 37.3% among early initiators (OR = 1.373, 95% CI = 1.316, 1.432) and 7.7% among middle initiators (OR = 1.077, 95% CI= 1.041, 1.116). Additionally, current smoking was associated with higher odds (OR = 1.369, 95% CI = 1.322, 1.417) of having additional health risk factors compared to former smoking, with one exception: current smokers had lower odds of obesity (OR = 0.566, 95% CI = 0.537, 0.597). Tobacco control programs to prevent adolescents from initiating smoking may have the potential to prevent other health risk factors in adulthood.

The Impact of Smoking and Multiple Health Behaviors on All-Cause Mortality

Four common health risk behaviors have the greatest impact on all-cause mortality risk, but studies are needed with larger samples and the appropriate age range for cigarette smokers. We examined the impact of smoking in the context of multiple health behaviors on all-cause mortality using a nationally representative sample of adults aged 30 and older in the United States. National Health Interview Survey data from 1997 to 2005 were linked to the National Death Index with a follow-up to December 2015. The primary dependent variable was all-cause mortality, and the primary predictors were smoking, heavy drinking, physical inactivity, and unhealthy weight (underweight or obesity). The sample contained 189,087 individuals (≥ age 30; population estimate = 140.7 million). Our primary statistical analysis tool involved fitting Cox proportional hazards models. Our findings demonstrated that smoking led to the highest mortality risk among the four risk behaviors examined, but more than half of smokers engaged in at least one additional health risk behavior. Smokers who engaged in multiple health behaviors experienced higher increased mortality risks: smoking combined with one other health risk behavior increased mortality risk by 32% and by 82% when combined with two behaviors. Engaging in all four risk behaviors more than doubled the mortality risk of smokers. Smoking cessation interventions that address multiple risk behaviors-physical inactivity, heavy drinking, and unhealthy weight-will likely prevent premature death better than interventions that address only smoking.

Oral Hygiene Practices and Dentition Status of Public Transport Workers of India- A Cross-sectional Study

OBJECTIVES

To evaluate the oral hygiene practices and dentition statuses of transport workers who were working in a public bus transport system (C.T.U.) of Chandigarh (U.T.), India.

MATERIALS AND METHODS

The data were recorded on a modified W.H.O. format (1997). A total of 1008 subjects constituted the final sample size. Information was obtained regarding the oral hygiene practices and clinical examinations were conducted. Statistical analysis was done by using ANOVA and Z-test.

RESULTS

The mean age of the subjects was 45.3 ± 7.8 years. Mean DMFT of the subjects who were not using tobacco in any form was 5.02. 80.2% (808). 88.7% of the subjects brushed their teeth as least once a day. Mean number of decayed and missing teeth were 1.67 ± 2.16 and 1.46 ± 2.8, respectively and their relation with age was found to be statistically significant.

CONCLUSION

Dental caries was found to be major indication in all the age groups. More elderly subjects than young needed extractions. This study emphasized the need of an improved dental awareness and availability of dental facilities to transport workers.
