Can the association between hypertension and physical activity be moderated by age?

Objectives

Physical inactivity, hypertension and non-communicable diseases are major public concerns across the globe. To our knowledge, there is a lack of research that has investigated the moderating effect of age on the relationship between hypertension and physical activity in developing countries. This study had two objectives: (1) investigating hypertension and sociodemographic factors associated with physical activity and (2) investigating whether age moderates the relationship between hypertension and physical activity.

Methods

Nationally representative data of Malaysia were used to generate cross-sectional evidence. The sample size was 2156 respondents. An ordered probit regression was utilized to assess factors associated with the practice of physical activity.

Results

Respondents aged 40-49 years with hypertension were 7.3% less likely to participate in high-level physical activity when compared to those without hypertension. The probability of having a low level of physical activity was 12.3% higher among hypertensive patients aged ≥60. Males, married individuals, less-educated adults, low-income earners, and individuals who were aware of their BMI, had a higher tendency to indulge in a highly active lifestyle than others.

Conclusion

The effect of hypertension on physical activity was moderated by age. Factors influencing physical activity levels among adults were income, gender, marital status, education, employment status, and BMI awareness.

Predicting exercise behaviors and intentions of Taiwanese urban high school students using the theory of planned behavior

PURPOSE

This study applied the Theory of Planned Behavior to predict exercise behaviors and intentions of teenagers and analyzed sex differences.

DESIGN AND METHODS

A prospective study design was employed to survey tenth-grade students in Taipei, Taiwan. The 951 participants reported their exercise attitudes, subjective norms, perceived behavioral control (PBC), and intentions, and their exercise behaviors were tracked 6 months later.

RESULTS

Results revealed that 22.1% of all students and more male students than female students exercised for ≥30 min/day on 5 or more days/week. Hierarchical multiple regression analyses demonstrated that intentions, PBC, attitudes, and subjective norms explained 32.5% of the variation in exercise behavior (p < .001). Intentions, attitudes, and PBC were related to exercise behavior regardless of sex. Attitudes, subjective norms, and PBC explained 67.0% of the variation in intentions (p < .001). Attitudes and PBC were related to intentions regardless of sex.

CONCLUSIONS

The findings support that the main constructs of the Theory of Planned Behavior can effectively predict regular exercise intentions and behaviors among adolescents.

PRACTICE IMPLICATIONS

The results can serve as a reference for nurses and other healthcare professionals when formulating effective strategies to encourage adolescents to engage in exercise practices.

Predict the exercise behavior intention of the older adults in Taipei City to promote exercise behavior

The purpose of this study employed the theory of planned behavior as a research framework to analyze the explanatory power of exercise attitude, subjective norms, and perceived behavioral control on exercise intention among older adults and to obtain insight on exercise behavior among older adults. The study used Ajzen's theory of planning behavior as a basis to compile the "Exercise Behavior Intention Questionnaire of the Older Adults." Results showed that there were significant differences were detected in the exercise intentions of older adults with different subjective norms and perceived behavioral control. This indicated that older adults of greater age have a greater need for companionship from family members and stronger subjective norms. In addition, exercise attitude, subjective norms, and perceived behavioral control explained the variance in exercise intention among older adults, verifying the positive explanatory power of these variables on exercise intention in older adults. The study concluded that the theory of planned behavior, improving older adults' exercise attitude alone was insufficient for increasing their exercise behavior intention. In particular, older adults of greater age had greater needs for social support from the main groups, and they required encouragement to enhance their self-efficacy and confidence.

Factors Associated with Nursing Students’ Intention to Report Needlestick Injuries: Applying the Theory of Planned Behavior

Background: Nursing students, like other healthcare workers, are prone to needlestick injuries. Over the years, studies have been conducted regarding needlestick injuries. However, its prevalence among Filipino nursing students’ is still not known. Also, nursing students’ intention to report needlestick injuries in the Philippines has not been explored.Purpose: The purpose of this research was to determine the factors associated with the intention to report needlestick injuries among nursing students applying the Theory of Planned Behavior.Methods: This cross-sectional study used the Needlestick Injuries Reporting Intention Scale (NIRIS) and was distributed among 233 senior nursing students in Iloilo City, Philippines. Descriptive statistics and Pearson’s correlation were utilized to analyze the data.Results: The results of the study revealed that 15% of nursing students had experienced a needlestick injury. However, only less than half (45.71%) of those who sustained needlestick injury reported the incident. Nursing students exhibited a positive attitude (M=5.41; SD=0.63) toward reporting needlestick injuries. They perceived a high social pressure (M=4.65; SD=0.46), high behavioral control (M=4.19; SD=0.45), and high intention (M=8.99; SD=1.15) in reporting needlestick injuries. Attitude (p=0.000), subjective norm (p=0.000), and perceived behavioral control (p=0.000) were significantly correlated with the intention to report needlestick injuries.Conclusion: This study supports the Theory of Planned Behavior in identifying factors influencing nursing students’ intention to report needlestick injuries.

Using social cognitive theory to explain physical activity in Iranian women preparing for pregnancy

Despite the known useful effects of regular physical activity during the preconception period on pregnancy outcomes, sedentary lifestyle is a prevalent phenomenon in reproductive-aged women. Using social cognitive theory (SCT) as its theoretical framework, the aim of this study was to explain physical activity model in the women preparing for pregnancy in Isfahan, Iran. This cross-sectional study was conducted on 220 Iranian women undergoing preconception care. The SCT constructs were measured using a researcher-made questionnaire. The duration of physical activity with moderate/severe intensity was also measured using the long form of the International Physical Activity Questionnaire. The data were analyzed using Spearman correlation coefficient and multivariable linear regression. The theoretical model was tested using structural equation modeling. The results showed that observational learning (β =.65, p <.0001) was the most important determinant of the physical activity level. The default model provided an adequate to good fit to the data (CMIN/DF = 2.10, p =.097). The results of the present study emphasized the role of observational learning in forming physical activity behavior in pre-pregnancy period; therefore, the design of interventions for providing the opportunity of observational learning may improve the level of physical activity among the women preparing for pregnancy.
