Outcome Measures

Primary Outcomes (3)

• Change of weekly Physical activity (minutes per week)

  Walking; moderate physical activity; vigorous physical activity The waist-worn accelerometer will be used to objectively assess PA (GT3X+, ActiGraph Inc, Pensacola, FL, USA). The Chinese version of the International Physical Activity Questionnaire-short form (IPAQ-C). If there is an increase, the result means a better outcome.

  Change from baseline to10 week follow-up

• Change of Fruit and Vegetable Intake (portions/day)

  To assess the fruit and vegetable intake during the past seven days, participants will be asked "how many portions of fruit they have today" and "how many portions of vegetables they have today". Participants were asked to keep a record for seven days, then to get an average for each day. If there is an increase, the result means a better outcome.

  Change from baseline to10 week follow-up

• Change of Meat, Fish, Egg & Alternatives (MFEA) (taels/day)

  To assess the Meat, Fish, Egg \& Alternatives consumption, individuals will be asked to answer three items. To assess the Meat, Fish, Egg \& Alternatives during the past seven days, participants will be asked "how many taels of meat do they have today", "how many taels of eggs do they have today" and "how many taels of Alternatives do they have today". Participants were asked to keep a record for seven days, then to get an average intake of Meat, Fish, Egg \& Alternatives for each day. If there is a change, and the follow-up result is between 5 and 6, the result is better.

  Change from baseline to10 week follow-up
