Brief Summary
Bone health is a significant public health issue in the United States. An estimated 10 million Americans age 50 and older are living with osteoporosis, and approximately 50% of women and 25% of men over age 50 will experience an osteoporosis-related fracture in their remaining lifetime. Recent research advancements have produced effective measures to improve and maintain bone health, including exercise, diet, screening tests, pharmacotherapies, and fall prevention strategies. These findings, however, have not been fully incorporated into the daily lives of adults, and many are unaware of the magnitude of bone-health problems. Thus, greater efforts must be made to effectively disseminate evidence-based research findings to improve bone health behaviors of the public. The Internet, with its increasing popularity, can be an effective tool in this endeavor. Despite a great deal of available online health resources, there has been a lack of research investigating effective methods to package and deliver these resources to yield positive public health outcomes. Expanding upon our prior findings and using an innovative approach combining two models of the social cognitive theory (SCT) and the RE-AIM framework (Reach, Effectiveness, Adoption, Implementation, Maintenance), in this proposal, we propose a large scale online study (N = 866) that will compare the long-term impact of two SCT-based online bone health interventions in adults age 50 and older targeting two large online communities. The two interventions are (1) an 8-week SCT-based Online Bone Health (TO-BoneHealth) program and (2) a 12-month TO-BoneHealth Plus program, including the TO-BoneHealth program followed by biweekly theory-based eNewsletters with follow-up of each individual's bone health behaviors ("booster" intervention) for 10 months. The interventions' impact will be assessed on the following the modified RE-AIM framework: (a) Effectiveness (knowledge, selected bone health behaviors, fall incidence, initiation of a discussion about bone health with a primary care provider, eHealth literacy); (b) Reach (number of participants the program reached); (c) Implementation (program usage); and (d) Maintenance (participants' bone health behavior maintenance). With the rapid growth of online communities, findings from this study will significantly contribute to current eHealth practice and research and serve as a dissemination model for other health promotion projects targeting online communities.

Outcome Measures
Primary Outcomes (3)
Changes in Osteoporosis Knowledge, Self-efficacy/Outcome Expectations for Calcium Intake and Exercise, Health Behaviors (Calcium Intake, Exercise)
The 16-item knowledge on osteoporosis was measured using the revised Osteoporosis Knowledge Test (Range: 0 - 23 \[higher better\]) The 11-item self-efficacy for calcium intake subscale of the Osteoporosis Health Belief Scale. (Range: 11 - 110 \[higher better\]) The 9-item self-efficacy for Exercise scale. (Range: 0 - 90 \[higher better\]) The 6-item calcium intake outcome expectation subscale of the Osteoporosis Health Belief Scale (Range: 6 -30\[higher better\]) The 9-item outcome expectations for Exercise Scale. (scoring: range: 9 - 45 \[higher better\])
8 weeks
Changes in Calcium Intake
Dietary calcium intake was estimated using a short screening tool developed by Blalock et al. 4. It includes 22 items that assess both frequency and portions various foods that contain calcium and vitamin D. (Higher values are better.)
8 weeks
Changes in Exercise Time
Exercise behavior was assessed using the 6-item exercise subscale that is part of the Yale Physical Activity Survey. (Higher value is better.)
8 weeks
Study Arms (3)
TO-BoneHealth Group
EXPERIMENTALThe group will use the 8-week TO-BoneHealth program, which includes: (1) web learning modules, (2) moderated discussion boards, (3) an Ask-the-Experts section, and (4) a virtual library. In addition, a tool kit and video lecture library are also available to participants. The program will be closed after 8 weeks, and there will be no eNewsletter or bi-weekly follow-ups of bone health behavior goal attainment. After 8 weeks, participants will receive a monthly e-mail informing them of the upcoming surveys.
TO-BoneHealth Plus Group
EXPERIMENTALThe group will use the TO-BoneHealth Plus program intervention, which includes the 8-week TO-BoneHealth program followed by bi-weekly theory-based eNewsletters with follow-up of each individual's maintenance of bone health behaviors for 10 months.
Control Group
NO INTERVENTIONNo specific intervention will be provided to the control group participants. To keep in contact with participants, a monthly e-mail will be sent to inform them of upcoming follow-up surveys. At the end of the study (upon completion of all five surveys), the control group participants will receive a CD version of the TO-BoneHealth program via mail.
Interventions
The 8-week TO-BoneHealth program include: (1) web learning modules, (2) moderated discussion boards, (3) an Ask-the-Experts section, and (4) a virtual library. In addition, a tool kit and video lecture library are also available to participants. The program will be closed after 8 weeks, and there will be no eNewsletter or bi-weekly follow-ups of bone health behavior goal attainment. After 8 weeks, participants will receive a monthly e-mail informing them of the upcoming surveys.
This intervention includes the 8-week TO-BoneHealth program followed by bi-weekly theory-based eNewsletters with follow-up of each individual's maintenance of bone health behaviors for 10 months.
