SPARC Facts 1997-2001

The CPI (Couch Potato Index)

The Push Play campaign and the New Zealand physical activity guidelines Movement=Health: Guidelines for Promoting Physical Activity (Hillary Commission 2001) recommend that adults do at least 30 minutes of moderate intensity4 physical activity, on most, if not all days of the week. Most days is defined as a minimum of five days per week. This recommendation is based on the US Surgeon General’s report Physical Activity and Health (1996) which found that 30 minutes moderate intensity physical activity, on most days of the week, is enough to maintain health and prevent some diseases (see page 23 for more information on why we need to be more active).

In addition to finding out about the total time adults are active per week we want to know how regularly active they are. To find this out, we have developed a CPI (Couch Potato Index) which measures the number of days in the last week that adults participate in sport or active leisure for 30 minutes or more, which tells us the proportion of adults who meet the physical activity guidelines (that is those who do at least 30 minutes of moderate physical activity on five days or more).

Regularity of physical activity

The results show that while 68% of adults are active for more than 2.5 hours per week, only four out of 10 adults (39%) are active for 30 minutes or more on at least five days a week. Just over four out of 10 people (42%) were active for 30 minutes or more on between one and four days. And almost two out of 10 adults (19%) had not taken part in any sport or physical activity in the previous week.

These results show that some people are reaching the 2.5-hour threshold by being active for more than 30 minutes on fewer than five days a week; for example by playing sport for 2.5 hours on a Saturday and not being active on any other day during the week. While these people are benefiting from the activity they do, they would benefit even more from regular activity and being active for at least 30 minutes on most other days of the week.

Readers should note that the chart below shows that 19% of adults were not active in the last week. This figure is higher than the 10% in the sedentary category in the chart on page 5, because the figure below also includes people who were active in the previous four weeks but not in the last week of those four weeks – these people are classed as relatively inactive in the earlier chart.

Four out of 10 adults are active for 30 minutes a day on five or more days a week

Ethnicity and gender

Māori men are more likely to be active on five or more days per week than their counterparts, especially men from other ethnic groups, who are more likely to be active on 1-4 days per week. Māori and European women are also more likely to be active on five days or more each week than Pacific women (who are more likely to be active on 1-4 days each week) or women from other ethnic groups. Women from other ethnic groups are more likely than any other women not to be active on any days.

Income and education

Adults with no secondary school education are more likely not to be physically active and are less likely to be active 1-4 days each week. However, there is a similar proportion of these adults who are active for at least 30 minutes a day on five or more days a week when compared to other adults.

Those adults who have a lower available household income are more likely to be physically active for 30 minutes a day on five or more days a week than those adults who have a higher available household income.

How active are adults compared to the same time last year?

Adults were asked to compare their level of activity to around the same time last year. 24% of adults spend more time being active compared to the same time last year. Those 25 years of age or over are more likely to spend the same amount of time being active compared to last year than adults aged 24 years or younger.

Māori, Pacific people and adults from other ethnic groups are more likely to spend less amount of time being active compared to last year. European adults, however, are more likely to spend around the same amount of time being active.

Why more active

The main reasons adults gave to explain why they are more active included wanting to be healthier and fitter (34%), wanting the enjoyment and challenge of becoming more active (16%), having more spare time (11%), losing weight and/or keeping their weight stable (10%) and having taken up a new sport or joining a gym (8%).

Why less active

28% of adults spend less time being active than at the same time last year. The main reasons why they are less active are increased workload/working longer hours (36%), general illness/injuries and operations (19%), limited time as a result of having a young family (15%), being too busy or having no time (12%) and being busy with study (8%).

Any information, advertising or promotion that changed adults’ activity levels

Adults were asked whether there was any information, advertising or promotion (anything that they had heard, read or seen) that had influenced them to do more or less sport or physical activity than last year.

Close to nine in 10 (88%) identified that their participation in sport and active leisure activities had not been influenced by anything they had seen, heard or read. There was little difference between men and women, and adults of different ages and ethnic groups.

The main sources of information/promotion that changed adults’ activity levels included magazines/ brochures/ newspapers/ books (28%), TV advertising/programmes (21%), a specific organisation (16%) and a gym promotion (10%). Close to one in 10 (9%) adults were influenced by their GP to change their level of activity.

Note: The sample sizes for adults aged 65+ years, Pacific adults and adults from other ethnic groups are very small. Use such figures with caution and treat them as only indicative and not conclusive.

Awareness of physical activity messages

Adults were also asked to rate the two statements that are reflected in the Push Play physical activity campaign to identify if people agree with key physical activity and health messages. The majority of adults (84%) agree that 30 minutes a day of physical activity is beneficial to their health. Close to three in five (59%) also agree that vigorous exercise for at least 20 minutes a time, three times a week, is beneficial to their health.

As adults grow older, however, they are more likely to disagree with the statement that vigorous exercise 20 minutes a time, three times per week, is beneficial to their health. Pacific, Māori and adults from other ethnic groups are more likely to agree with the statement than Europeans, as the following table shows.

Stair climbing

Adults were asked on how many days over the past week they climbed one or more flights5 of stairs. 68% of adults indicated that they used stairs in the last seven days. Adults aged 65 years or over, Māori and Pacific adults are less likely to use stairs.

Adults were also asked to estimate the number of flights of stairs they had used each day in the past week. Of those adults who used the stairs in the last seven days, around a third of adults climbed between 1-4 flights of stairs per day, 32% between 5-10 stairs and 34% of adults climbed 11 or more flights of stairs.

The following table shows results by gender and adults of different ages and ethnic groups. As adults grow older they are less likely to climb more than 9-10 flights of stairs.

4 Moderate intensity physical activity is defined as activity that will cause a slight but noticeable increase in breathing and heart rate (a good example is brisk walking).

5 A flight of stairs is one storey.
