Tobacco and alcohol use, fruit and vegetable consumption, physical activity habits, and participation in routine checkups and cancer screenings among adults aged 40 and older with and without chronic diseases: A cross-sectional study.
Adults with chronic diseases tend to use less tobacco and alcohol, do less physical activity, and have more routine checkups and cancer screenings, but these behavioral differences show strictly small to moderate effect sizes, suggesting real-world changes following a chronic disease diagnosis may be modest.
Key Findings
Results
People with chronic diseases used tobacco and alcohol less frequently than those without chronic diseases.
Data drawn from the Turkey Health Survey-2022 with 12,555 participants aged 40 and older
Chronic disease status was used as the grouping variable across 29 variables
Both frequentist and Bayesian bivariate analyses confirmed this pattern
Effect sizes for these associations were described as 'strictly small to moderate'
Results
Adults with chronic diseases engaged in less physical activity compared to those without chronic diseases.
Finding was consistent across both frequentist and Bayesian statistical methods
Physical activity habits were among the 29 variables analyzed
Effect sizes remained small to moderate, suggesting modest real-world differences
The study population was 52% female, 42.8% overweight, and 46.8% reported good general health
Results
Adults with chronic diseases participated more in routine checkups and cancer screenings than those without chronic diseases.
Participation in routine checkups and cancer screenings was higher in the chronic disease group
This pattern was detected by both frequentist and Bayesian analyses
Effect sizes for screening participation were also characterized as small to moderate
Sample included 12,555 adults aged 40 and older from the Turkey Health Survey-2022
Results
Fruit and vegetable/salad consumption was similar between adults with and without chronic diseases.
No meaningful difference in fruit and vegetable consumption was detected between the two groups
This finding held across both statistical approaches used in the study
Fruit and vegetable consumption was one of 29 variables analyzed
The result suggests chronic disease diagnosis does not markedly alter dietary habits related to produce consumption
Results
Frequentist and Bayesian bivariate tests yielded similar results, but multivariable logistic regression revealed critical divergences between the two approaches.
Both bivariate frequentist and Bayesian tests produced consistent findings across the health behavior variables
In multivariable logistic regression models, the Bayesian approach acted as 'a more conservative filter against weak predictors'
The divergence between methods in multivariable models was described as a 'critical' difference
The authors recommend placing more emphasis on effect sizes alongside frequentist or Bayesian approaches in future health research and policy-making
Results
All statistically significant associations between chronic disease status and health behaviors were characterized by strictly small to moderate effect sizes.
Effect size evaluation was conducted alongside both frequentist and Bayesian analyses
The authors conclude that 'while behavioral shifts following a chronic disease diagnosis are statistically detectable, the real-world changes might be modest'
Small to moderate effect sizes were found across tobacco use, alcohol use, physical activity, and screening participation
The authors suggest public health interventions should offer 'targeted programs tailored to patients' limitations rather than generic advice'
Methods
The study population from Turkey Health Survey-2022 was predominantly middle-aged and older adults with notable rates of overweight status and chronic disease.
Total sample size was 12,555 people aged 40 years and older
52% of participants were female
42.8% were classified as overweight
46.8% reported good general health
Chronic disease diagnosis served as the primary grouping variable
What This Means
This research examined whether adults aged 40 and older who have been diagnosed with a chronic disease behave differently in terms of smoking, drinking, eating fruits and vegetables, exercising, and getting health checkups and cancer screenings compared to those without chronic diseases. Using a large national health survey from Turkey with over 12,500 participants, researchers found that people with chronic diseases do tend to smoke and drink less, exercise less, and attend more routine medical checkups and cancer screenings. However, fruit and vegetable consumption was about the same between the two groups.
Importantly, while these differences were statistically detectable, the actual size of these differences was small to moderate — meaning that in practical terms, having a chronic disease does not dramatically transform a person's health behaviors. This suggests that a diagnosis alone is not enough to produce large-scale lifestyle changes, and that public health programs may need to offer more personalized, targeted support rather than one-size-fits-all advice, especially taking into account physical limitations that chronic disease patients may face.
The study also compared two different statistical methods — traditional (frequentist) and Bayesian approaches — and found that while they agreed on basic comparisons, they diverged when analyzing multiple factors simultaneously, with the Bayesian method being more cautious about identifying weak associations as meaningful. The researchers recommend that future health studies and policymakers pay closer attention to effect sizes (how large a difference actually is) rather than relying solely on whether a result is statistically significant.
