Adolescent and young adult males account for a large proportion of dengue cases reported through national surveillance systems in the Western Pacific Region. To preliminarily assess the validity of these observed distributions, a field investigation was conducted in the Lao People's Democratic Republic's Savannakhet Province in November 2011.
Mixed quantitative and qualitative methods were used. Dengue surveillance data from Savannakhet Province, and aggregate hospital admission data from the Savannakhet Provincial Hospital for outpatients and inpatients were analysed by age and sex. Unstructured informal interviews were conducted with local health care workers, primary and secondary school officials and villagers.
An excess of males was found among reported dengue cases in Savannakhet Province in the 15-49 year age group. Females in the same age group, however, were found to access health care more than their male counterparts. Qualitative assessments attributed this distribution to young females being more health-conscious and having greater health care-seeking behaviour.
The excess of male dengue cases in the surveillance data appeared to be associated with a truly higher risk of dengue rather than greater health care access or health care-seeking behaviour by young men. This investigation indicated the importance of assessing the reported surveillance data within the context of health care utilization behaviour of the population under surveillance.
在西太平洋区域通过国家监测系统报告的登革热病例中，青少年和青年男性占很大比例。为初步评估这些观察到的分布情况的有效性，2011年11月在老挝人民民主共和国沙湾拿吉省进行了一次实地调查。
采用定量和定性相结合的方法。按年龄和性别分析了沙湾拿吉省的登革热监测数据以及沙湾拿吉省医院门诊和住院患者的综合入院数据。与当地医护人员、中小学官员和村民进行了非结构化的非正式访谈。
在沙湾拿吉省报告的15 - 49岁年龄组登革热病例中，男性病例过多。然而，发现同一年龄组的女性比男性更频繁地寻求医疗服务。定性评估将这种分布归因于年轻女性更注重健康且有更强的就医行为。
监测数据中男性登革热病例过多似乎与登革热的实际较高风险有关，而非年轻男性有更多的医疗服务可及性或就医行为。这项调查表明，在受监测人群的医疗服务利用行为背景下评估报告的监测数据非常重要。
