Family average income and diagnosed Type 2 diabetes in urban and rural residents in regional mainland China.

Aims: To explore the relationship between family average income (FAI; an index of socio-economic status) and Type 2 diabetes in a region of mainland China. Methods: Population-based cross-sectional study, conducted between October 2000 and March 2001 in administrative villages (n = 45) randomly selected from three urban districts and two rural counties of NanJing municipality, mainland China, with a regional population of 5.6 million. Participants were all local residents aged ≥ 35 years old (n = 29 340); 67.7% from urban areas, 32.3% from rural areas, 49.8% male and 50.2% female. Results: The response rate of eligible participants was 90.1%. The overall prevalence of self-reported Type 2 diabetes was 1.9%. After adjustment for possible confounding variables (age, gender, area of residence, body mass index, educational level, smoking status, occupational and leisure-time physical activity), participants in the higher and middle FAI categories were more than twice as likely to have Type 2 diabetes as those in the lower FAI category. Conclusions: The prevalence of Type 2 diabetes is positively related to socio-economic status (indexed by FAI) in Chinese at the population level. After controlling for potential confounding factors, people in higher socio-economic status groups are more likely to have Type 2 diabetes. These associations are consistent with other effects of epidemiological transition and identify a need for preventive initiatives.

Family average income and body mass index above the healthy weight range among urban and rural resicents in regional Mainland China

Objective: To explore the relationship between family average income (FAI; an index of socio-economic status) and body mass index (BMI; a widely used, inexpensive indicator of weight status) above the healthy weight range in a region of Mainland China. Design: Population-based cross-sectional study, conducted between October 1999 and March 2000 on a sample of regular local residents aged 35 years or older who were selected by random cluster sampling. Setting: Forty-five administrative villages selected from three urban districts and two rural counties of Nanjing municipality, Mainland China, with a regional population of 5.6 million. Subjects: In total, 29 340 subjects participated; 67.7% from urban and 32.3% from rural areas; 49.8% male and 50.2% female. The response rate among eligible participants was 90.1%. Results: The proportion of participants classified as overweight was 30.5%, while 7.8% were identified as obese. After adjusting for possible confounding variables (age, gender, area of residence, educational level, occupational and leisure-time physical activity, daily vegetable consumption and frequency of red meat intake), urban participants were more likely to be overweight or obese relative to their rural counterparts, more women than men were obese, and participants in the lowest FAI tertile were the least likely to be above the healthy weight range. Conclusions: The proportion of adults with BMI above the healthy weight range was positively related to having a higher socio-economic status (indexed by FAI) in a regional Chinese population.

International comparisons of construction industry performance: further investigations

While there have been many attempts at comparisons of construction performance over the past 50 years, the results have generally been inconclusive and/or contradictory.

Such comparisons are of great interest to industry, governments and theorists alike but there is little agreement as to how they are best done. A variety of methodologies have been used, however, the lack of satisfactory outcomes has been due largely to one factor, the lack of a truly reliable method for comparing construction costs in different currencies

Exchange rates are recognised as being unsuitable, and while purchasing power parity (PPP) has a long history, the method still has many critics. In addition, the nature of the building industry and its products makes the establishment of reliable construction PPPs very difficult. Both the UN’s International Comparison Program (ICP) and the European Union gather data for the production of construction-specific PPP indices, but neither body publishes them, as there is too much doubt about their reliability.

New approaches are being developed and some are soon to be trialled. This paper looks at the problems, describes and discusses some new approaches, and assesses their potential.

Neighbourhood renewal community survey Corio and Norlane : volume 2 : comparisons: 2005 & 2007

This second volume presents the data from the 2005 and 2007 rounds of the Corio and Norlane Neighbourhood Renewal Community Surveys. The focus of this report is on change in the responses of participants between the two time periods. All of the data presented has been previously provided – in the 2005 report, and the 2007 data in the first volume of the current report. The comparison tables are presented separately for the NRA participants and for the control group participants.

Colac neighbourhood renewal community survey : volume 2 : comparisons: 2004 & 2007

This second volume presents the data from the 2004 and 2007 rounds of the Colac Neighbourhood Renewal Community Surveys. The focus of this report is on change in the responses of participants between the two time periods. All of the data presented has been previously provided – in the 2004 report, and the 2007 data in the first volume of the current report. The comparison tables are presented separately for the NRA participants and for the control group participants. The control group sample was stratified according to the SEIFA classification system. Data from the lowest 3 SEIFA deciles and the highest three SEIFA deciles are utilized in the report to provide some indication of differences in responses between participants of most to least disadvantage within the control group

What are we really evaluating when we rank journals : Comparisons of views

This paper examines differences in academics perceptions of how journals should be evaluated in terms of their prestige, contribution to theory, contribution to practice and contribution to teaching. Comparisons are made between individual and institutional weightings, regional variations and whether an individual works at an institution offering a PhD/DBA. Some differences were identified, suggesting that that evaluative criteria used to rank journal may be influenced by employment situations.
