Do Regular Cholesterol Screenings Lead to Lower Cholesterol Levels and Better Health Behaviors for All? Spotlight on Middle-Aged and Older Adults in the United States

Health shocks and changes in preventive behaviors: Results from the China Health and Retirement Longitudinal Study

Background

China is facing the challenge of rising prevalence and ballooning burden of chronic non-communicable diseases (NCDs); however, the Chinese middle- and older-aged population considerably lack preventive behaviors. Health shocks (HS), widely defined as sudden health deterioration brought on by diseases or accidents, bring a “teachable moment” to motivate changes in preventive behaviors.

Objective

This study aims to examine the effect of HS on changes in preventive behaviors, including personal health practices and preventive care utilization.

Methods

HS was defined as any five chronic disease diagnoses (cancer, heart disease, stroke, diabetes, and hypertension). The impacts of HS on smoking, drinking, and exercise, physical examination were estimated. The panel data of 13,705 respondents were obtained from the latest two waves of the China Health and Retirement Longitudinal Study (CHARLS) in 2015 and 2018. A multilevel propensity score match difference-in-difference (multilevel PSM-DID) model was constructed.

Results

HS significantly decreased smoking (OR = 0.59, p < 0.05) and drinking (OR = 0.62, p < 0.01) and increased the utilization of auxiliary inspection in physical examination (OR = 1.19, p < 0.1). Major HS had significantly considerable and specific effects on reducing smoking and drinking (OR = 0.37 and 0.56, p < 0.01), while minor HS had relatively small effects on reducing smoking (OR = 0.74, p < 0.05) and drinking (OR = 0.69, p < 0.01), but extensive effects on initiating exercise (OR = 1.32, p < 0.05), physical examination (OR = 1.18, p < 0.1), and auxiliary inspection (OR = 1.30, p < 0.05).

Conclusion

After HS, there is a teachable moment to promote positive changes in preventive behaviors. Guided by the 5A's brief intervention model (Ask, Advise, Assess, Assist, Arrange), tailored interventions should be targeted at these populations to reduce the risk of the progression and complications of existing diseases, prevent the related comorbidity, and prolong the expected life-span.

Development and validation of the geriatrics health behavior questionnaire (GHBQ)

BACKGROUND

Considering the importance of health behaviors in health outcomes, it is necessary to assess health behaviors precisely. This study aimed to develop and validate The Geriatrics Health Behavior Questionnaire among Iranian older adults.

METHODS

This cross-sectional and methodological study was conducted on 420 community older adults (age ≥ 60) through random multi-stage sampling. The initial questionnaire has been developed with 22 items and seven subscales based on an extensive literature review, evaluation of related questionnaires, and experts' opinions. Face and content validity were evaluated by interviewing 10 older adults and 18 specialists. The construct validity was evaluated via Known-groups validity and convergent validity. The reliability of the questionnaire was calculated by internal consistency, test-retest, and absolute reliability.

RESULTS

The face validity was conducted by using interviews with older adults and gathering the specialists' opinions. The items were grammatically and lexically corrected accordingly. Two items were deleted due to CVR < 0.44. Modified Kappa statistic (K*) and I-CVI for all items were higher than 0.88. The average content validity index (S-CVI/Ave) value was 0.94. Three items were deleted to improve the internal consistency; the final GHBQ consisted of 17 items with Cronbach α = 0.72. Acceptable convergent validity was approved by a significant correlation between GHBQ and SF8™ health survey (r = 0.613, P value< 0.001). Independent t-test showed that older adults with education level ≥ high school have significantly higher health behavior scores than those with education level < high school (11.93 ± 2.27 vs. 9.87 ± 2.35, t = - 9.08, p < 0.001). Intra-class correlation coefficient (ICC) for the total questionnaire was 0.92 (95% CI =0.84 to 0.96). Standard Error Measurement (SEM) and Minimal Detectable Change (MDC95) were 0.71 and 1.98, respectively.

CONCLUSION

The present study results showed that the Geriatrics Health Behavior Questionnaire had suitable validity and reliability among Iranian older adults. It is recommended to consider its comprehensiveness and yet its briefness in other populations after passing validation.
