Market advice.

Within the Hong-kong, middle school students is divided in to about three university groups-rings 1, dos and you can step three relative to the educational achievement. The fresh scaled external and internal evaluation marks of all students had been ordered. They have been equally put into about three college or university rings and you will allocated to help you supplementary schools, per composed of 1 / 3 of your own final number of people . Into the SES, month-to-month house incomes from HK$ 0–14,999, HK$15,000–30,999 and you may HK$>31,100 denoted the low-, medium- and you will high-money class, correspondingly. New typical-earnings classification earns the latest average monthly home-based home money .

Analytical study

Pearson’s Tool-Moment Correlation was utilized in order to compute brand new correlations involving the properties out of perceived PL and PA account. Numerous regression study was used to examine the latest connection between your perceived PL and PA levels of men and women users. Detailed analytics of your own participants’ group recommendations, eg sex, amounts height (junior and you can senior supplementary), university ring and you will SES was considered about Pearson’s Tool-Second Relationship to help you calculate the latest relationship anywhere between imagined PL and you can PA profile. The fresh z-ratings within correlations were determined to look at whether or not those products had been somewhat more . SPSS adaptation 22 to own Window was applied to your investigation investigation. Brand new trust height are put since the 95% (P ? 0.05) to keep up mathematical accuracy.


The fresh new teens reported its imagined PL typically since the (±dos.dos2), (±dos.11) and you can (±step 1.90) toward around three elements, ‘sense of self and you will thinking-confidence’, ‘self-phrase and you can correspondence having others’ and you will ‘training and you will understanding’, respectively. The mediocre every day PA some time intensity are 74 times at the a taking walks pace, having 34 minutes within a method pace and you will twenty-seven minutes within a vigorous rate, and this met the principles suggesting at the very least an hour every day away from contribution in just about any MVPA (61 times). The time spent in different PA domain names try typically, 47 moments in school, 17 moments in the home, 66 minutes during the transport and you will 48 times during sport.

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 people up coming searched elements away from sex, degrees top, college or university band and you can SES as well as their affect the connection between seen PL and you may PA profile, because the found inside the Dining table step 3. All of the groups presented extreme certainly correlations ranging from perceived PL and you will PA.
