Smoking as a risk factor for physical impairment: a systematic review and meta-analysis of 18 cohort studies

Tobacco use among adults with disabilities in nine countries-Demographic and Health Survey, 2016-2021

Few studies have investigated tobacco use among people with disabilities living in low- and middle-income countries (LMICs). We aimed to examine current tobacco use among men and women with disabilities using Demographic and Health Survey (DHS) data from 9 LMICs. We considered a respondent currently use tobacco products if they reported current use of any combustible/smoked tobacco products or smokeless tobacco products. We performed secondary analyses of DHS data from 2016-2021 collected in Haiti, Mali, Mauritania, Nigeria, Pakistan, Rwanda, South Africa, Timor-Leste, and Uganda. We examined marginal effects in logistic regression to calculate the adjusted prevalence and adjusted prevalence differences of tobacco use by disability status, controlling for selected sociodemographic characteristics. The adjusted prevalence of current use of tobacco products among women with a moderate/severe disability, mild disability, and no disability varied across countries, with medians of 1.9% (range = 0.1% [Mali] to 11.3% [Pakistan]), 3.2% (range = 0.9% [Nigeria] to 13.3% [South Africa]), and 2.3% (range = 0.5% [Nigeria] to 8.9% [South Africa]), respectively. For men with moderate/severe disability, the median adjusted prevalence for current use of tobacco products was 18.8% (range = 8.9% [Rwanda] to 55.0% [Timor-Leste]). The median prevalences of current use of tobacco products for men with mild disability and no disability were similar to those with moderate/severe disability, at 16.5% and 15.9%, respectively. Current tobacco product use among people with disabilities varied for countries included in our study; however, with few exceptions, current tobacco product use was similar across disability status groups. Additional research is warranted to determine whether our findings extend beyond the nine countries assessed here. It is important to consider the needs of people with disabilities in tobacco prevention, control, and cessation efforts so that this substantial population can benefit equitably from such programs, interventions, or policies.

Can adult children's education prevent parental health decline in the short term and long term? Evidence from rural China

This paper presents the first evidence of the causal relationship between adult children's schooling and changes in parental health in the short and long term. By using supply-side variation in schooling as an instrument for adult children's education and a representative dataset for rural China, we find that adult children' education has a positive influence on the long-term changes in parental health, with limited evidence of any short-term effect. Our results remain consistent after a variety of sensitivity tests. The heterogeneous analyses show differences in socio-economic status and gender, with low-educated parents and mothers being the primary beneficiaries of children's schooling. Potential mechanisms for the long-term effects of adult children's education on changes in parental health include better chronic disease management, improved access to health, sanitation, and clean fuel facilities, improved psychological well-being, and reduced smoking behaviours.

Smoking may compromise physical function long before it kills you

Introduction

Although prior research has demonstrated an association between smoking and worse physical function, most of those studies are based on older people and do not evaluate whether the age-related increase in physical limitations differs by smoking history. We quantify how the magnitude of the smoking differential varies across age.

Methods

This cohort study comprised a national sample of Americans aged 20-75 in 1995-1996, who were re-interviewed in 2004-2005 and 2013-2014. Our analysis was restricted to respondents who completed the self-administered questionnaires at Wave 1 (N = 6,325). Follow-up observations for those respondents were included if they completed the self-administered questionnaires at Wave 2 (N = 3,929) and/or Wave 3 (N = 2,849). The final analysis sample comprised 13,103 observations over a follow-up period of up to 19 years (1995-2014). We used a linear mixed model to regress physical limitations on smoking status at baseline adjusted for sex, age, race, socioeconomic status, alcohol abuse, drug abuse, and obesity with an interaction between age and smoking to test whether the age pattern of physical limitations differed by smoking history. Additional models incorporated measures of smoking duration and intensity.

Results

In the fully-adjusted model, smokers exhibited a steeper age-related increase in physical limitations than never smokers. Thus, the disparities in physical limitations by smoking status widened with age but were evident even at young ages. The estimated differential between heavy smokers and never smokers rose from 0.24 SD at age 30 to 0.49 SD at age 80. At younger ages, heavy smokers who quit recently fared worse than current light smokers and not much better than current heavy smokers.

Discussion

We know smoking is bad for our health, but these results reveal that differences in physical limitations by smoking history are evident even at ages as young as 30. Physical limitations that emerge early in life are likely to have an especially large impact because they can jeopardize health for decades of remaining life. Smoking probably will not kill you at young age, but it may compromise your physical function long before it kills you. Just do not do it.

Exploring the difference between men and women in physical functioning: How do sociodemographic, lifestyle- and health-related determinants contribute?

Background

To explore whether differences between men and women in the sensitivity to (strength of the association) and/or in the exposure to determinants (prevalence) contribute to the difference in physical functioning, with women reporting more limitations.

Methods

Data of the Doetinchem Cohort Study was used (n = 5856, initial ages 26–70 years), with follow-up measurements every 5 years (up to 20). Physical functioning (subscale SF-36, range:0–100), sex (men or women) and a number of socio-demographic, lifestyle- and health-related determinants were assessed. Mixed-model multivariable analysis was used to investigate differences between men and women in sensitivity (interaction term with sex) and in exposure (change of the sex difference when adjusting) to determinants of physical functioning.

Results

The physical functioning score among women was 6.55 (95%CI:5.48,7.61) points lower than among men. In general, men and women had similar determinants, but pain was more strongly associated with physical functioning (higher sensitivity), and also more prevalent among women (higher exposure). The higher exposure to low educational level and not having a paid job also contributed to the lower physical functioning score among women. In contrast, current smoking, mental health problems and a low educational level were more strongly associated with a lower physical functioning score among men and lower physical activity and higher BMI were more prevalent among men.

Conclusions

Although important for physical functioning among both men and women, our findings provide no indications for reducing the difference in physical functioning by promoting a healthy lifestyle but stress the importance of differences in pain, work and education.

Self-treatment attempt of tobacco use disorder with Melissa officinalis: a case report and brief review of literature

In the treatment of tobacco use disorder, current approaches focus on pharmacotherapy, nicotine replacement, and psychotherapy. However, traditional treatments have been widely used in societies for the purpose of smoking cessation for years. Although cases using traditional herbs in the self-treatment of addiction have been reported in the literature, studies on this subject are very limited. Research on certain herbs shows that they may be effective in the treatment of tobacco use disorder by different mechanisms, however, there is no evidence that they are safe to consume as cigarettes. This article aims to question the place of traditional herbs in tobacco use disorder treatment through a case who started to smoke Melissa officinalis herb to help his nicotine withdrawal.
