Behavioral interventions modestly increased physical activity among healthy adults

A new study from the American Journal of Public Health reports that interventions to increase activity among healthy adults should emphasize behavioral strategies over cognitive strategies.

Researchers analyzed what types of interventions where most successful in encouraging healthy adults to exercise. Their study included data from 99,011 participants. The average age was 44 years. Analysis suggested that the characteristics of the most effective interventions were behavioral interventions instead of cognitive interventions, face-to-face delivery versus mediated interventions, and targeting individuals instead of communities. Cognitive interventions target knowledge, attitudes or beliefs; whereas behavioral strategies include goal setting, self-monitoring, physical activity behavior feedback, consequences, exercise prescription and cues.  

The study’s authors stated, ”These findings suggest that interventions to increase physical activity should emphasize behavioral components such as self-monitoring, stimuli to increase physical activity, rewards, behavioral goal settings, and modeling physical activity behavior in standardized interventions delivered to individuals. Future research should explore which components of behavioral interventions are most effective.”

Racial minorities more likely than non-Hispanic Whites to be light, intermittent smokers

Researchers used data on adults aged 20 to 64 years from the 2003 Tobacco Use Supplement to the Current Population Survey to examine racial/ethnic disparities in smoking behaviors, smoking cessation and factors associated with cessation among U.S. adults. They found no evidence to indicate that racial/ethnic minorities had greater success in quitting smoking compared to non-Hispanic Whites even though they were more likely to be light and intermittent smokers.  Compared to non-Hispanic Whites, racial/ethnic minorities were not less likely to receive advice from health professionals to quit smoking, but they were less likely to use nicotine replacement therapy.

 

The study’s authors argue that interventions to increase smoking cessation, along with models of cigarette addiction and the quitting process, have been generally based on non-Hispanic White populations who have markedly different smoking patterns than racial/ethnic minority groups.  They conclude that the aggregate of their findings suggest traditional conceptualizations of cigarette addiction and the quitting process may need to be adapted for various racial/ethnic minority groups.

A shift in approach of substance abuse treatment may be beneficial  

 

The timing and approach for substance abuse treatment aimed at reducing abstinence and mortality rates are found to be significant influencers in success rates, according to a new study published in the American Journal of Public Health. Results indicate the need to shift the addiction treatment field from an acute care model to a chronic disease management paradigm.

 

Researchers examined the relationship between substance abuse treatment, abstinence and mortality in a sample of individuals entering treatment and estimated overall mortality rates and the extent to which they varied according to demographic, clinical severity and treatment variables. They used data from a 9-year longitudinal study of 1,326 adults entering substance treatment on the west side of Chicago of whom 131 died (nine percent of total sample group). In order to predict mortality rates, baseline predictors of initial and long-term response and substance abuse patterns were used. They found that the likelihood of mortality decreased directly as the total number of treatment episodes increased but increased with increasing percentage of time in treatment. In addition, the likelihood of sustained abstinence increased with increases in the number of treatment episodes in the first six months.  

 

The study’s authors conclude, “Contrary to many current managed care practices, our findings indicate the need for more aggressive screening, early intervention, adequate initial treatment, ongoing monitoring, disease management skills, and better linkage to recovery support services and mutual aid groups that help sustain recovery.”
