Objective To explore the
risk of developing
metabolic syndrome (MS) by using the data from cohorts involving people having received
screening programs for physical check-up,in three areas of
China (
Beijing,
Hongkong and
Taiwan).
Methods A total number of 6 828 non-metabolic syndromic
adults,
who received
physical examination for the first
time and with
records kept for longer than 5 years (between 2004 and 2010) at the MJ centers,were recruited.Criteria developed by the
Joint Committee for Developing
Chinese Guidelines on Prevention and
Treatment of
Dyslipidemia in
Chinese Adults in 2007 (JCDCG-2007) was used for defining the
metabolic syndrome.Cox proportional
hazards regression model was used to examine the difference of the
risk of developing MS among the three cohorts that received the
health screening programs.Results The standardized
incidence densities of MS were 3.14 per 100
person-years,2.19 per 100
person-years and 2.03 per 100
person-years in the cohorts of
Beijing,
Hongkong and
Taiwan,respectively.After adjusting for
gender,age,
cigarette smoking,
dietary patterns at the baseline,the HRs for people in
Beijing and
Hongkong were 1.60 (95%CI1.34-1.91) and 1.08 (95%CI0.83-1.41) respectively,in developing MS,when compared with people from
Taiwan.Factors as being
male,
elderly,
cigarette smoking,
meat/
food intake dietary pattern and MS components at the baseline all showed significantly positive effects on the
risk of developing MS.Conclusions There were significant differences regarding the
risk of developing MS among
health screening people from the
Beijing,
Hongkong and
Taiwan.Factors as being
male,
elderly,
cigarette smoking,
meat/
food intake,
dietary pattern and MS components at the baseline appear to be the
risk factors for developing the MS.
