BACKGROUND Evidence indicated a high prevalence of physical inactivity and insufficient consumption of fruit and vegetables among college students. Web-based interventions for multiple health behavior change (MHBC) appears to be a promising approach to change the unhealthy habit. Limited research has tested this assumption in promoting physical activity (PA) and fruit-vegetable consumption (FVC) among Chinese college students. Moreover, the best sequential delivery mode of MHBC intervention needs to be addressed. OBJECTIVE From both quantitative and qualitative perspectives, this study aimed to examine (1) the effectiveness of two sequentially delivered 8-week web-based interventions on PA, FVC and health-related outcomes, and (2) which sequential timing is superior in behavior change. The intervention content was based on the health action process approach. Self-reported data were evaluated including PA, FVC, and health-related outcomes (Body Mass Index (BMI), depression and quality of life). METHODS In a randomized controlled trial (RCT), 552 eligible college students (Mean = 19.99 ± 1.04 years, 58.3% female) were randomly assigned to one of three groups: PA-first (4 weeks of PA followed by 4 weeks of FVC intervention), FVC-first (4 weeks of FVC followed by 4 weeks of PA intervention), and a control group (8 weeks of placebo treatment unrelated to PA and FVC). A total of 4 web-based assessments were conducted, including at baseline (T1, n = 565), after 4 weeks (T2, after the first behavior intervention, n = 486), after 8 weeks (T3, after the second behavior intervention, n = 420), and after 12 weeks (T4, 1-month post-intervention follow-up, n = 348). In addition, after the completion of the entire 8-week intervention, 18 participants (Mean = 19.56 ± 1.04 years, 55.6% female) who completed the whole program were immediately invited to attend one-to-one and face-to-face semi-structured interviews. The participants were asked about their experience of participating in this program regarding their changes in health behaviors and health-related outcomes. The entire study was conducted throughout the fall semester of 2017. RESULTS Both quantitative and qualitative data supported superior effects on PA, FVC and BMI in two sequential intervention groups compared to the control group. In addition, the quantitative data found no significant behavior change differences between two sequential intervention groups after 8 weeks. But FVC-first group contributed to more maintenance of FVC compared to the PA-first group after 12 weeks. Findings from the qualitative study revealed that both intervention groups reported superior effects for the first addressed behavior after 8 weeks. CONCLUSIONS This study provides comprehensive evidence for the effectiveness of sequentially delivered web-based MHBC interventions on PA and FVC among Chinese college students. The efficacy of two sequential timing interventions on behavior change is mixed in quantitative and qualitative data. The delivery mode of MHBC interventions in the future is discussed.

Lifestyle Physical Activity

Background Memory loss in older age affects women more than men and cardiovascular disease is a leading risk factor. Physical activity can improve memory in healthy older adults; however, few physical activity interventions have targeted women with cardiovascular disease, and none utilized lifestyle approaches. Purpose The purpose of this study was to examine feasibility, acceptability, and preliminary effects of a 24-week lifestyle physical activity intervention (physical activity prescription, five group meetings, and nine motivational interviewing calls). Methods A sequential mixed-methods approach was used. Participants were 18 sedentary women ≥65 years with cardiovascular disease and without cognitive impairment recruited in August 2017. Feasibility, acceptability, self-reported health, accelerometer-assessed physical activity, and neurocognitive memory tests were measured using a pre-post test design. Two post-intervention focus groups ( n = 8) were conducted in June 2018. Concept analysis was used to identify barriers/motivators of intervention participation. Results Meeting attendance was >72% and retention was 94%. Participants rated the program with high satisfaction. There were significant improvements at 24 weeks in self-rated physical health, objective daily steps, and estimated cardiorespiratory fitness ( d = .30–.64). Focus group themes generated recommendations for modifying the intervention. Conclusion Findings support adapting the intervention further for women with cardiovascular disease and testing it in an efficacy trial.

Data Investigation

The purpose of this research is to find out how college students in Saudi Arabia utilize their smartphones in their learning and to find out the effect of its use in their learning and investigate ways that are more effective for such use. In order to achieve this goal, a researcher developed questionnaire was distributed to 93 college students. The study utilized a mixed-methods approach in collecting data. Investigation Results are analyzed and demonstrated with charts, followed by a discussion of the main findings.
