Brief Summary

The purpose of this study is to determine whether folate and vitamin B12, physical activity and mental health literacy can prevent depression, and folate and vitamin B12 and physical activity can prevent cognitive impairment in older people. Also the study aims to assess the benefits for older people in improving their knowledge about mental health in relation to depression.

Outcome Measures

Primary Outcomes (1)

• Depression

  The Patient Health Questionnaire - 9 (PHQ - 9) is a brief self-administered diagnostic instrument for depressive symptoms with items derived from the nine diagnostic criteria for Major Depression Disorder using the DSM - IV. The items are coded "0" (not at all) to "3" (nearly every day) for the most recent 2-week period, with possible scores ranging from 0 to 27, higher scores indicating greater depression severity. The PHQ - 9 is used in research and clinical settings, and can be administered via telephone. Studies support its reliability, validity, and ability to detect change over time.

  Baseline, 6 weeks, 6-, 12-, 48-, and 51 month followups.

Secondary Outcomes (6)

• Physical activity level

  Baseline, 6 weeks, 6-, 12-, 48-, and 51 month followups.

• Cognitive impairment

  Baseline, 12-, and 48-month followups.

• Physical health outcomes

  Baseline, 6-week, 6-, 12-, 24-, and 48-month followups.

• B12 levels

  Baseline, 12-, and 48-month followups.

• Folate status

  Baseline, 12-, and 48-month followups.

Study Arms (6)

Folic acid (400mcg) + Vitamin B12 (100 mcg)

EXPERIMENTAL

The vitamin intervention was a daily oral dose of one tablet consisting of folic acid 400 mcg + vitamin B12 100 mcg. The folic acid dose of 400 mcg / day was selected as it has been shown to be the dose associated with 90% of the maximal decrease in plasma homocysteine concentration for older individuals. Participants received 1 bottle x 200 tablets in six-month supplies at baseline, 6 months, 12 months, and 18 months. Adherence was monitored by telephone interviews (6 weeks, 6-, 12-, and 24 months) and 10 brief telephone tracking calls (1 - 5 weeks, and 4-, 8-, 13-, 18-, and 22-months).

Drug: Folate (400mcg) and Vitamin B12 (100 mcg)

Mediated physical activity promotion

EXPERIMENTAL

Individuals in the Physical Activity Promotion group received a manual designed to promote older individuals' physical activity participation to the level recommended to gain both physical and mental health benefits. The framework of the physical activity manual was informed by social cognitive theory and the transtheoretical model, and comprised five sections that reflect stages of behaviour change, including; precontemplation, contemplation, preparation, action, and maintenance. The manual contained evidence-based strategies and skills to assist people in increasing their physical activity levels. Participants received a pedometer at the commencement of the intervention as pedometry step / minute values are useful as an indicator of moderate to vigorous physical activity with total number of steps for one week recorded during the brief telephone calls at 1-5 weeks, and 4-, 8-, 13-, 18-, and 22- months.

Behavioral: mediated physical activity promotion

Mental health literacy

EXPERIMENTAL

This MHL intervention comprised 10 modules, with nine of these specifically written for older adults. Modules 1 to 5 comprised information on depression and the evidence-based treatment for older adults. The additional MHL modules were booklets addressing evidence-based strategies and treatments for depression. It was delivered in a way to foster support and ensure that participants worked through the material systematically. Modules 1 to 5 were delivered in consecutive weeks as previous research indicates that the maximum impact of MHL on depressive symptoms may occur within the first six weeks of the intervention. Telephone interviewers contacted participants once a week for 5 consecutive weeks to motivate and support participants. There were an additional 5 check-in telephone calls, and Modules 6 to 10 of the MHL material that were delivered via postal mail at 4- (Module 6), 8- (Module 7), 13- (Module 8), 18- (Module 9), and 22- months (Module 10).

Behavioral: Mental health literacy

Placebo tablet

PLACEBO COMPARATOR

A placebo tablet was the attention control intervention for the folic acid + vitamin B12 intervention group. Participants received 1 bottle x 200 tablets in 6-month supplies at baseline, 6 months, 12 months, and 18 months. Adherence was monitored by telephone interviews (6 weeks, 6-, 12-, and 24 months) and 10 brief telephone tracking calls (1 - 5 weeks, and 4-, 8-, 13-, 18-, and 22-months) during which participants counted their left-over tablets.

Drug: placebo

Nutrition information

ACTIVE COMPARATOR

The attention control intervention for the physical activity intervention was printed nutrition literacy and included information concerning the recommended dietary guidelines for older Australians, as well as strategies and additional information to facilitate beneficial dietary behaviours. The same procedure was adhered to as the physical activity intervention to ensure adequate attention control. Participants in the nutrition promotion intervention received 5 brief telephone calls from an interviewer to facilitate adherence to the intervention, and to offer support and clarification of the materials. Participants received five further brief telephone calls as well as nutrition newsletters that were delivered via postal mail at 4-, 8-, 13-, 18-, and 22- months.

Behavioral: Nutrition information

Pain and arthritis management information

ACTIVE COMPARATOR

Pain and Arthritis Information was used as the attention control intervention for the MHL intervention and comprised 10 modules. Modules 1 to 5 were contained in an Arthritis Australia consumer guide for arthritis management. Modules 6 to 10 were a series of information pamphlets on pain management, osteoporosis and falls prevention. The delivery of the Pain Information was identical to the MHL intervention with Modules 1 to 5 distributed via postal mail in five consecutive weeks (1-5 weeks), while the remaining intervention modules were delivered at 4- (Module 6), 8- (Module 7), 13- (Module 8), 18- (Module 9), and 22- months (Module 10). Participants also received 10 brief calls from a telephone interviewer that coincided with receiving the print intervention materials.
