To compare and contrast the prevalence of pneumoconiosis in two groups of former migrant mineworkers in southern Africa, and to examine the effectiveness of the South African compensation system for occupational lung diseases.
Comparison of two cross-sectional studies and follow-up data on compensation results.
The village of Thamaga, Botswana and the rural area of Libode, Eastern Cape, South Africa.
Two hundred and thirty-four former underground mineworkers in Thamaga, and 238 in Libode.
Prevalence and severity of pneumoconiosis, prevalence of radiological signs of tuberculosis (TB), Medical Bureau for Occupational Diseases (MBOD) certification committee decisions, and compensation results.
Prevalence of pneumoconiosis > or = 2/1 was 15.4% in Libode and 13.6% in Thamaga. Significantly more Libode than Thamaga subjects (51.1% versus 29.0%) reported past TB treatment. Radiological signs of pulmonary TB were also more prevalent in Libode (33.3% v. 23.9%). Twenty-six per cent of Libode men and 16.1% of Thamaga men were certified with compensable disease. Libode payments were finalized within 30 months, whereas Thamaga cases only began receiving payments 52 months after medical examination, with 11 cases still pending 66 months after medical examination.
There was a high prevalence of pneumoconiosis in both study groups. Many men were eligible for compensation but were previously uncompensated. The higher rate of compensable disease in the Libode group may relate to the higher prevalence of TB, as well as more active follow-up by the study group, including a large number of appeals. Socio-political changes in South Africa between 1994 and 1996 may also have influenced compensation results.
比较和对比南部非洲两组前流动矿工尘肺病的患病率，并检验南非职业肺病赔偿系统的有效性。
两项横断面研究及赔偿结果随访数据的比较。
博茨瓦纳的塔马加村和南非东开普省的利博德农村地区。
塔马加的234名前地下矿工和利博德的238名前地下矿工。
尘肺病的患病率和严重程度、肺结核（TB）放射学征象的患病率、职业病医疗局（MBOD）认证委员会的决定以及赔偿结果。
利博德尘肺病患病率≥2/1为15.4%，塔马加为13.6%。报告曾接受过结核病治疗的利博德受试者显著多于塔马加受试者（51.1%对29.0%）。利博德肺结核的放射学征象也更普遍（33.3%对23.9%）。26%的利博德男性和16.1%的塔马加男性被认证患有可获赔偿疾病。利博德的赔偿在30个月内敲定，而塔马加的病例在体检后52个月才开始获得赔偿，11例在体检后66个月仍未处理完毕。
两个研究组尘肺病患病率均较高。许多人符合赔偿条件，但此前未获赔偿。利博德组可获赔偿疾病发生率较高可能与结核病患病率较高以及研究组更积极的随访有关，包括大量上诉。1 994年至1996年南非的社会政治变革也可能影响了赔偿结果。
