Yet, in their implementation, the interventions evaluated varied by the age and occupational group of the population targeted, gender, risk level for CVD; the length of intervention; or the implementing body be it general practitioners, legislators or researchers.
Categories 1 to 3 were of adequate size to perform analyses, but DOT 4 was of insufficient size, as only 48 subjects were included and no occupational groups of at least 10 workers were present.
On account of the small number of subjects in each specific industry or occupation, we analysed risk in major industrial and occupational groups, and found an increased risk of lung cancer among men who had ever been employed as 'bricklayers, carpenters, and other construction workers'.
Nonetheless, the study cohort covers a broad range of companies and occupational groups.
Significant differences were seen between the genders, age and occupational groups in regard to co-use of drugs and herbs (Table 1).
For the 1800s, they include also socio-economic information such as household sizes, the economic standard of households, and occupational groups in the parish, although for women, the latter information is less reliable.
Analyses of labour market outcomes in Australian youth cohorts typically find effects for gender, socioeconomic background, test scores and labour force experience on earnings, unemployment and occupational group, net of educational qualifications (Huq 2014; Hérault et al. 2012; Marks and Fleming 1998a, b; Buchler and Dockery 2015; Marks 2005).
Occupation was categorised into the broad occupational groups of manufacturing, removal, insulation, and 'other' work, and the occupation reported most often was used.
Furthermore, we identified that death among the occupational groups of farmers and laborers was less likely to be caused by TB (aOR 0.43, CI 0.19 0.94) and more likely to be due to AOI, ie, the base outcome in the analysis.
Logistic regression analyses were performed to analyse the relationship between current or heavy smoking rate and occupational group in terms of the prevalence ratio (PR).
