The cross-sectional study entitled Health Profile of Skaraborg County, 1977 (HPS 77), forms part of an evaluation of a care programme for persons suffering from high blood pressure. Concurrently with the implementation of the study, epidemiological data were collected concerning the health profile of an entire county, with the aim of facilitating comparisons between the municipalities in the county. This paper describes how the study was implemented and gives an analysis of non-participation and validity. A comparison is made between participants and non-participants with regard to record data obtained from the National Health Insurance Fund, hospital records and the register of the Temperance Board. The non-participants differ in most respects from the participants, who have a more marked pattern of disorders in their case histories. In a longitudinal non-participants analysis, participants are compared with non-participants with respect to mortality during the following four-year period. In this study the non-participants differed, in having a higher mortality rate. The validity of the questionnaire is discussed on the basis of three different analyses. The validity varied considerably, depending on the questions studied. For example, 53% of those with myocardial infarction in the questionnaire were confirmed in hospital records. This was also true for 62% of those with stroke and 49% of those with angina pectoris in a follow-up interview. Medication for hypertension was confirmed in 94%. Ten of twelve participants who reported three or more symptoms of mental disorders were confirmed at interview with a physician. Studies like HPS 77 could be useful when planning preventive as well as curative measures. Thus it is important to describe not only the implementation of the study, but also its validity and the importance of non-participation for the results presented.
题为《1977年斯卡罗堡县健康状况》（HPS 77）的横断面研究，是对一项高血压患者护理计划评估的一部分。在开展该研究的同时，收集了有关整个县健康状况的流行病学数据，目的是便于该县各市政当局之间进行比较。本文描述了该研究的实施方式，并对未参与情况和有效性进行了分析。就从国家健康保险基金、医院记录和戒酒委员会登记册获得的记录数据，对参与者和未参与者进行了比较。未参与者在大多数方面与参与者不同，参与者在病历中有更明显的疾病模式。在一项纵向未参与者分析中，比较了参与者和未参与者在接下来四年期间的死亡率。在本研究中，未参与者的死亡率较高。基于三种不同分析对问卷的有效性进行了讨论。有效性差异很大，这取决于所研究的问题。例如，问卷中有心肌梗死的患者中，53%在医院记录中得到证实。在后续访谈中，中风患者的这一比例为62%，心绞痛患者为49%。高血压用药在94%的情况下得到证实。报告有三种或更多精神障碍症状的12名参与者中，有10名在医生访谈时得到证实。像HPS 77这样的研究在规划预防和治疗措施时可能会有用。因此，不仅要描述研究的实施情况，还要描述其有效性以及未参与情况对所呈现结果的重要性，这一点很重要。
