The new participants’ demographic information, such sex, level height, college ring and you may SES, has also been amassed

Market recommendations.

Inside the Hong-kong, middle school people is actually split up into around three school bands-bands step 1, 2 and you will 3 according to its educational completion. The new scaled external and internal comparison scratches of the many students was basically purchased. Chances are they had been equally split into around three school rings and you may assigned in order to additional universities, each consisting of 1/3rd of one’s final number away from students . For the SES, monthly family profits out of HK$ 0–fourteen,999, HK$fifteen,000–31,999 and you may HK$>31,one hundred thousand denoted the reduced-, medium- and you can high-money classification, respectively. The latest average-earnings classification earns new average month-to-month domestic family income .

Analytical analysis

Pearson’s Tool-Moment Correlation was used to help you compute the fresh new correlations amongst the features of seen PL and PA levels. Several regression data was applied to look at new association involving the perceived PL and you may PA quantities of men and women people. Detailed statistics of your own participants’ market pointers, including intercourse, values height (junior and you may senior second), college ring and you may SES were believed regarding Pearson’s Unit-Time Relationship to compute this new correlation between identified PL and PA profile. The fresh new z-ratings between your correlations have been determined to look at whether the individuals examples had been somewhat other . SPSS version 22 to have Windows was used with the investigation analysis. The newest believe height is lay as 95% (P ? 0.05) to keep mathematical accuracy.


The latest kids reported its understood PL an average of just like the (±dos.22), (±dos.11) and you may (±step 1.90) towards around three elements, ‘feeling of self and worry about-confidence’, ‘self-phrase and communications which have others’ and you can ‘studies and you may understanding’, respectively. Their average everyday PA some time strength is 74 times from the a walking speed, that have 34 moments on a media speed and you may twenty seven minutes in the an energetic speed, which met the principles indicating at the least an hour every single day of participation in any MVPA (61 minutes). Enough time invested in numerous PA domain names is actually typically, 47 minutes at school, 17 moments at home, 66 times throughout transportation and you may 48 moments during recreation.

Table 1 shows the significant correlations between the perceived PL and PA levels (r = 0.227, p < 0.01) of the Hong Kong adolescents measured by the PPLI and IPAQ-A. Although the correlations are modest, components of perceived PL, intensities of PA levels and three domains (school, transportation, and recreation) of PA were significantly correlated (r = 0.067–0.292, p < 0.01). No significant correlation was found for the home domain.

A multiple linear regression was calculated to predict the PA levels of participants based on their perceived PL attributes. Preliminary analyses were performed to ensure no violations of the assumptions of normality, linearity and multicollinearity. Table 2 shows the significant regression equation (F (3, 1941) = , p < 0.01), with an R 2 of 0.052. The participants predicted PA levels were –5490 + 366.1 (sense of self and self-confidence) + (self-expression and communication with others) + (knowledge and understanding) MET minutes when the attributes of perceived PL were measured on a 5-point Likert Scale. The results showed that sense of self and self-confidence (? = 0.123, p = 0.000), self-expression and communication with others (? = 0.071, p = 0.003) and knowledge and understanding (? = 0.082, p = 0.007) were positively related to PA level. The participants' mean PA levels increased by 366.1, and MET minutes for each attribute score of perceived PL. All attributes of perceived PL were significant predictors of PA level.

The study party upcoming browsed the standards from intercourse, grade level, college or university ring and SES as well as their influence on the partnership between perceived PL and you can PA accounts, while the shown in Dining table step 3. All teams presented significant surely correlations anywhere between thought of PL and you may PA.
