Weight status, quality of life, and cigarette smoking among adolescents in Washington State

Quality of life and associations with health-related behaviours among older adults with increased cardiovascular risk

BACKGROUND AND AIMS

A better understanding of the relationship between cardiovascular disease risk factors and quality of life (QoL) in older age is needed to inform development of risk reduction strategies. This cross-sectional study investigated the association of QoL with health-related behaviours in older adults at risk of heart failure.

METHODS AND RESULTS

Older adults (N = 328) at risk of heart failure residing in Melbourne, Australia, provided data on QoL and health-related behaviours including physical activity, diet, smoking and alcohol consumption. Multiple linear regression modelling was used to examine associations between health-related behaviours, QoL and its constituent domains. After adjustment for age, gender, body mass index and comorbidities, current smoking was found to have a negative association with the mental component score (MCS) of QoL (β = -0.174, p ≤ 0.01), with a positive association seen between MCS and physical activity (β = 0.130, p = 0.01). Current alcohol use had a positive association with the physical component score (PCS) (β = 0.120, p = 0.02) and saturated fat intake consumption had a negative association with the physical functioning domain of QoL (β = -0.105, p = 0.03) but was not associated with either PCS or MCS.

CONCLUSION

Engagement of older adults at increased cardiovascular risk with behavioural risk factor modification using QoL as a driver of change may offer new opportunities to promote healthy ageing. Development of such strategies should consider that for some behaviours which are cardiovascular risk factors (alcohol intake, in particular), the positive association to QoL is complicated and needs further deliberation.

Self-rated health and health-related quality of life are related with adolescents' healthy lifestyle

OBJECTIVES

Self-rated health (SRH) and health-related quality of life (HRQoL) are related with health outcomes. It is expected that these constructs are also associated with healthy behaviours. Thus, the present study sought to analyse the associations between a healthy lifestyle composite score and SRH and HRQoL among adolescents.

STUDY DESIGN

This was an observational, cross-sectional study.

METHODS

Data were obtained from the cross-sectional health behaviour in school-aged children (HBSC) 2014 Portuguese survey. Participants were 5024 adolescents (2373 boys), aged 10-17 years. A composite score of healthy lifestyle was obtained using the combination of the following factors: daily physical activity, sleep at least 8-9 h/night, daily consumption of fruit and vegetables, spend <2 h daily in screen-based behaviours, never drink and never smoke.

RESULTS

Adolescents with a healthy lifestyle had significantly better SRH and higher HRQoL than those who were not engaged in all healthy behaviours.

CONCLUSIONS

Healthy lifestyle (composed of physical activity, sleep at least 8-9 h/night, daily consumption of fruit and vegetables, spend <2 h daily in screen-based behaviours, never drink and never smoke) is related to SRH and HRQoL. Promoting a comprehensive approach to these behaviours is a public health strategy to be considered when aiming to improve health, in general, and SRH and HRQoL, in particular.

Adolescent Weight and Electronic Vapor Product Use: Comparing BMI-Based With Perceived Weight Status

INTRODUCTION

This study examined the associations of BMI-based and perceived body weight status with electronic vapor product use, cigarette smoking, and dual use among U.S. adolescents.

METHODS

A cross-sectional analysis was conducted in 2017 on data from 15,129 adolescents in the National Youth Risk Behavior Survey, 2015. Multiple logistic regression analyses were used to examine the associations of BMI-based and perceived weight status with electronic vapor product use, cigarette smoking, and dual use, after adjusting for all other covariates. The regression models were stratified by gender.

RESULTS

Overall, 25.5% of males used electronic vapor products, 11.6% smoked cigarettes, and 8.1% used both; percentages among females were 22.6%, 9.8%, and 6.8%, respectively. Females who perceived themselves as overweight were more likely than those who perceived themselves as normal weight to be current electronic vapor product users (AOR=1.09, 95% CI=1.01, 1.19) and dual users (AOR=1.23, 95% CI=1.01, 1.49). When compared with normal BMI-based category, males with obese BMI status were more likely to be current cigarette smokers (AOR=1.61, 95% CI=1.06, 2.44), however, only females with overweight BMI status were more likely to be current smokers (AOR=1.89, 95% CI=1.25, 2.86).

CONCLUSIONS

Findings suggest that the influence of adolescents' body weight perceptions and BMI-based status should be accounted for when developing nicotine-containing product use prevention programs for adolescents. Specific strategies for influencing female adolescents who perceive themselves as overweight should be included to prevent emerging electronic vapor product and dual use.

Weight Status and Cigarette and Electronic Cigarette Use in Adolescents

INTRODUCTION

Research shows that adolescents who are overweight or obese may be at greater risk of cigarette smoking, and that this relationship may vary by gender. However, this relationship is understudied for electronic cigarettes (e-cigarettes). Given the high rate of adolescent obesity and the rise in e-cigarette use in adolescents, this relationship should be investigated.

METHODS

Data are from the third wave (collected October 2015-January 2016) of the Texas Adolescent Tobacco and Marketing Surveillance system. Students were in the seventh, ninth, and 11th grades (n=2,733) from five counties surrounding four major Texas metropolitan areas (Houston, Austin, San Antonio, Dallas). Weighted logistic regression was used to determine if weight status (healthy weight, overweight, or obese) was correlated with ever and past 30-day cigarette or e-cigarette use, controlling for sociodemographics. Models were stratified by gender. Data analyses were conducted in March 2017.

RESULTS

Compared with healthy-weight boys, obese boys had higher odds of past 30-day e-cigarette use (AOR=3.45, 95% CI=1.34, 8.33) and cigarette smoking (AOR=4.52, 95% CI=1.32, 15.51). There was no significant relationship between weight status and cigarette or e-cigarette use in girls.

CONCLUSIONS

This study supports that there is a positive relationship between weight status and past 30-day cigarette and e-cigarette use for boys, but that there is no association for girls.

Psychometric properties of the Ruminative Response Scale-short form in a clinical sample of patients with major depressive disorder

BACKGROUND

The Ruminative Response Scale (RRS)-short form is one of the most widely used measures of rumination, comprising ten items and two components: reflection and brooding. The aim of this study was to investigate RRS validity and reliability in a clinical sample of French patients with major depressive disorder (MDD).

SUBJECTS AND METHODS

Outpatients with a DSM-IV-TR diagnosis of MDD were recruited from a public academic hospital in France. Depressive symptoms were evaluated by the Beck Depression Inventory, anxiety by the State-Trait Anxiety Inventory - state scale, and quality of life by the 36-Item Short Form Health Survey (SF-36) questionnaire. Confirmatory factor analyses, item-dimension correlations, Cronbach's α-coefficients, Rasch statistics, and external validity were tested. Differential item functioning analyses were performed for sex.

RESULTS

A total of 109 patients participated. The final reflection-brooding two-factor model of the RRS showed a good fit (root-mean-square error of approximation 0.041, comparative fit index 0.987, standardized root-mean-square residual 0.048) after removing one item (daily diary writing). Internal item consistency and reliability were satisfactory for the two dimensions. External validity testing confirmed that RRS scores were correlated with Beck Depression Inventory, State-Trait Anxiety Inventory, and SF-36 scores. There was no differential item functioning across sexes.

CONCLUSION

These results demonstrated good scale reliability and validity for assessing rumination in patients with MDD.

Stigma, Obesity and Adolescent Risk Behaviors: Current Research and Future Directions

Adolescents are particularly vulnerable to risk behaviors as, in this life stage, they are experiencing intense physical, psychological and social changes. Adolescents who are overweight/obese, but particularly those who perceive themselves as such, are more likely to engage in risk behaviors than those who are or perceive themselves of normal-weight. Weight stigma and discrimination may contribute to this association as they reinforce poor body image and create intense stress. Stress is associated with poor emotion regulation, more impulsive, contextually-determined, and less rational decision-making, leading to greater engagement in risk behaviors. However, pathways from weight stigma/discrimination to risk behavior may be moderated by adolescents' social networks. This review provides a conceptual model and empirical evidence to illustrate the proposed pathways from weight stigma and discrimination to risk behaviors. Public health implications and future research directions are also discussed.

The relationship between disordered eating and cigarette smoking among adult female twins

OBJECTIVE

While previous studies have shown a link between cigarette smoking and disordered eating (DE), it is less clear whether this association can be explained by attempts to control weight and/or temperament. This study had two aims: to examine weight/shape and DE symptomatology associated with weight control-related smoking and disordered eating; second, to investigate whether temperament-based factors explain the association between compensatory smoking and weight and shape-related characteristics, and disordered eating symptoms.

METHOD

Female twins (N = 1,002) from the Australian Twin Registry, aged 28-39 years, were assessed by interview yielding lifetime diagnostic information of disordered eating and use of cigarette smoking for weight control. Self-report measures of temperament were available.

RESULTS

Women who had never smoked (50.6%, n = 495) or had smoked for reasons other than weight and shape control (42.5%, n = 415) were generally not differentiated with respect to indicators of disordered eating. Women who smoked for reasons primarily associated with weight and shape control (6.9%, n = 67) had significantly higher levels of disordered eating than non-smokers identified as being higher levels of purging (OR = 4.55, 95% CI = 2.41-8.59) and fasting (OR = 9.32, 94% CI = 4.43-19.90) but not objective binge episodes (OR = 1.69, 95% CI = 0.71-3.99). Of those women diagnosed with lifetime eating disorders, weight-control smokers had higher levels of purging (OR = 4.22, 95% CI = 1.13-15.80) than those who did not. There were no differences in temperament.

DISCUSSION

Results support co-occurrence of smoking for weight control and purging in both community and clinical groups, and indicate this association is related to weight control and not temperament.
