We studied the inheritance of migraine and concomitant symptoms among 2690 monozygotic (1524 female and 1166 male) pairs and 5497 dizygotic (2951 female and 2546 male) twin pairs. Our material consists of a population-based questionnaire study among Finnish twins in 1981. The definition of migraine is based on a questionnaire method. Concordance was assessed using probandwise concordance rates and tetrachoric correlations for monozygotic (MZ) and dizygotic (DZ) twin pairs. For estimating the contribution of genetic factors to the susceptibility of migraine, a polygenic multifactorial model was used. Structural equation models were applied for estimating variance components and to compare different genetic models. Nearly one-half (40% to 50%) of the liability to migraine is attributable to genetic factors. In all structural analyses, the model with both additive genetic and unshared environmental component had the best goodness-of-fit value. The genetic component varied between 34% to 51% in different migraine types. There were no remarkable differences between sexes except in the effects due to dominance, where the proportion was 26% for men and 14% for women. Concomitant symptoms among subjects within pairs concordant for headache had genetic effects varying from 56% (subjects with unilaterality) and 56% (subjects with visual symptoms) to 45% (persons with nausea and vomiting). The two threshold model of headache points to the continuum model of headache, and the thresholds represent different levels of severity of the pain. Our results emphasize a multifactorial and higher than previously reported genetic pattern in the etiology of migraine. Also unshared environmental factors play an important role.

The aim of this article is to describe women's experiences of being pregnant and having insulin-dependent diabetes mellitus (IDDM), particularly regarding what the crucial elements of the experience are during pregnancy. A qualitative method with a hermeneutic phenomenological approach was used. The subjects were 14 pregnant women with IDDM, of whom eight were primiparous and six multiparous. They were interviewed during pregnancy concerning their experience of 'being controlled by blood glucose levels for the child's sake'. The child makes demands, with consequences which are divided into two main themes: objectification, including loss of control and an awareness of having an unwell 'risky body'; and exaggerated responsibility, including constant worry, constant pressure and constant self-blame. The results present a challenge to every midwife, physician or other health professional involved in the care of pregnant women with diabetes. They have an important role in mediating understanding of how risks to such women during pregnancy and childbirth can be minimized by normalizing the blood glucose level. At the same time, they should point out the fact that most women with IDDM today have healthy babies. This could reduce negative feelings. The women should also be supported and encouraged in the normal transition to motherhood.

In Africa today one of the main strategies to reduce malaria infection during pregnancy is the promotion of intermittent preventive treatment (IPT). To date only a few studies have investigated the factors affecting compliance to IPT. This medical anthropology study aims to describe these factors from the perspective of pregnant women in rural Malawi. We examine women's knowledge and perceptions about the use of medication in pregnancy and the timing and motivation concerning use of antenatal clinic (ANC) services. In addition, the circumstances and interaction at the ANC and the IPT implementation process are described. The data were collected by applying an ethnographic approach, including focus group discussions (n=8), in-depth interviews (n=34), drug identification exercises, participant observation and a 'knowledge, attitudes and practices' survey (n=248). This study discovered several factors affecting IPT. These were: unclear messages about IPT with sulfadoxine-pyrimethamine (SP) from nurses; timing of SP-1; periodic shortages of SP; women's limited understanding of IPT-SP; tendency for late enrolment; and nurses' underperformance. The results of this study show that understanding of the multiple contexts affecting malaria prevention is important, and that ethnographic research is useful for discovering and solving problems beyond the scope of many other research approaches.

This study investigated Finnish nurses' experiences and views on end-of-life decision making and compared them with physicians' views. For this purpose, a questionnaire was sent to 800 nurses, of which 51% responded. Most of the nurses had a positive attitude towards and respect for living wills, more often than physicians. Most also believed that a will had an effect on decision making. Almost all of the nurses considered it their responsibility to talk to physicians about respecting living wills. Do-not-resuscitate (DNR) orders were often interpreted to imply partial or complete palliative (symptom-orientated) care, which may cause confusion. Half of the nurses reported that a DNR decision was discussed always or often with a patient who was able to communicate; physicians were more positive in this respect. Surprisingly, many nurses (44%) stated that active treatment continued too long. Two-thirds thought that their opinions were taken into account sufficiently, even though only half believed that, in general, they had some impact.

Mental and somatic health was compared between older Somali refugees and their pair-matched Finnish natives, and the role of pre-migration trauma and post-migration stressors among the refugees. One hundred and twenty-eight Somalis between 50-80 years of age were selected from the Somali older adult population living in the Helsinki area (N = 307). Participants were matched with native Finns by gender, age, education, and civic status. The BDI-21 was used for depressive symptoms, the GHQ-12 for psychological distress, and the HRQoL was used for health-related quality of life. Standard instruments were used for sleeping difficulties, somatic symptoms and somatization, hypochondria, and self-rated health. Clinically significant differences in psychological distress, depressive symptoms, sleeping difficulties, self-rated health status, subjective quality of life, and functional capacity were found between the Somali and Finnish groups. In each case, the Somalis fared worse than the Finns. No significant differences in somatization were found between the two groups. Exposure to traumatic events prior to immigrating to Finland was associated with higher levels of mental distress, as well as poorer health status, health-related quality of life, and subjective quality of life among Somalis. Refugee-related traumatic experiences may constitute a long lasting mental health burden among older adults. Health care professionals in host countries must take into account these realities while planning for the care of refugee populations.
