The following strategy is likely to be most effective in supporting an adolescent's efforts to lose weight:

Three reasons why the ZAZI campaign has been introduced to address the same challenges are:

1. New HIV infections, unplanned pregnancies, mother-to-child transmission of HIV and gender-based violence are still very common.
2. Earlier campaigns were not effective enough in dealing with these problems.
3. SANAC wanted to combine the efforts of different campaigns into one.

Three factors that could prevent people living in poverty from taking care of their health are:

1. Limited access to health care services, for example because clinics are far away and there is no transport.
2. Poor nutrition because they cannot afford a balanced diet.
3. A lack of money to pay for specialised health care.

Three factors influencing the current eating habits of young people which could contribute to obesity are:

1. There are more fast-food outlets and online delivery services than ever, which makes it very easy for young people to eat unhealthy food often.
2. The media constantly advertises fast food in an attractive way, so young people are drawn to these foods instead of healthy meals.
3. Busy parents often do not have time to cook nutritious meals, so young people do not get balanced meals and turn to junk food.

Two reasons why proper planning is important when committing to an action plan to improve your health are:

1. Proper planning helps you break your health goal into small, realistic milestones. You can then track your progress and measure short-term results, which keeps you motivated and makes it more likely that you will reach your final goal.
2. Proper planning makes you aware of risks and obstacles, such as a busy timetable or limited money, before they happen. Because you have prepared for these barriers, you can adjust your activities when needed instead of giving up, which increases your chance of success.

Two reasons why some patients do not complete the treatment of their lifestyle diseases are:

1. Some patients start to feel better after a while and think they no longer need the medication, so they stop taking it before the treatment is finished.
2. The treatment may have unpleasant side effects, such as nausea or tiredness, which discourages patients from continuing with it.

Two practical activities that young people could initiate to raise awareness about heart diseases in their school communities are:

1. Young people could invite health professionals to give talks at school about heart diseases. This informs all learners about the causes and warning signs. As a result learners can discuss their own health concerns and make better choices to protect their hearts.
2. Young people could arrange with the Department of Health for a mobile clinic to do free blood pressure and cholesterol tests at school. This gives everyone an easy chance to be tested. In this way learners may find out about heart problems early and get treatment in time.
