  • Immigrant and native regular general practitioners in Norway. A comparative registry-based observational study

    by Esperanza Diaz, Ali Raza, Hogne Sandvik, Stefan Hjorleifsson

    Background: More than 10% of the population and nearly 20% of all general practitioners (GPs) in Norway have an immigrant background. There are reasons to believe that immigrant GPs have different demographic characteristic and serve different populations than native GPs. Objectives: To describe the characteristics of the lists and population subscribed to immigrant GPs in Norway and compare them with those of Norwegian-born GPs. Methods: Immigrant GPs were defined as persons born abroad with both parents from abroad. Two national registers were linked with information about all inhabitants and GPs in Norway in 2008: the GPs Database, and the National Population Register. Logistic regression was used to study the influence of the GP's immigrant background on different characteristics. Results: Compared to native GPs, immigrant GPs are younger, more often women, and more frequently work alone and in rural areas. GPs with immigrant background have a higher proportion of immigrant patients (OR = 3.2; 95% CI: 2.7–3.8), not only from their own culture, but also from other cultures, and this proportion increases over time. Immigrant GPs have more difficulties recruiting patients compared to their native colleagues (OR = 0.3; 95% CI: 0.3–0. 4 for having closed lists), but this difference seems to diminish over time. There are, however, substantial differences between immigrant GPs from different areas of the world. Conclusion: The characteristics of the populations assigned to GPs with or without immigrant background are different. This should be taken into account when studying differences between immigrant and native GPs.

    Immigrants’ use of emergency primary health care in Norway: a registry-based observational study

    by Hogne Sandvik, Steinar Hunskaar, Esperanza Diaz

    Emigrants are often a selected sample and in good health, but migration can have deleterious effects on health. Many immigrant groups report poor health and increased use of health services, and it is often claimed that they tend to use emergency primary health care (EPHC) services for non-urgent purposes. The aim of the present study was to analyse immigrants’ use of EPHC, and to analyse variations according to country of origin, reason for immigration, and length of stay in Norway.


  • Immigrant general practitioners in Norway: A special resource? A qualitative study

    by Esperanza Díaz, Stefán Hjörleifsson

    Aims: To explore whether and how immigrant general practitioners (GPs) in two major cities in Norway think that their own ethnic background affects their practices and their work. Methods: Qualitative focus group and individual interviews with seven immigrant GPs, five men and two women, age 36—65 years. Their clinical experience in Norwegian primary health care ranged from four to 30 years. Analysis was conducted by systematic text condensation. Results: First, immigrant GPs described a gradual process of becoming bicultural: the GPs communicate with immigrant patients on their own terms and draw upon their special knowledge from abroad to help selected patients, while also adapting to Norwegian cultural expectations of the GP’s role. Second, the GPs described being aware of cultural issues in consultations with immigrant and Norwegian patients, but rarely making these issues explicit. The GPs ventured that cultural awareness, together with their personal experience in their own countries and as immigrants in Norway, made them able to sometimes help immigrant patients better than Norwegian GPs. Third, immigrant GPs experienced a big workload related to immigrant patients, but they accepted this as a natural part of their work. Fourth, immigrant GPs felt that they had to work harder and be more careful than their Norwegian colleagues in order to avoid complaints from patients, and to be accepted by colleagues. Conclusions: Immigrant GPs express broad cultural competence and keen cultural awareness in their consultations. The immigrant background of these GPs could be considered as a special resource for clinical practice.

    Effect of Reducing Indoor Air Pollution on Women's Respiratory Symptoms and Lung Function: The RESPIRE Randomized Trial, Guatemala

    by Tone Smith-Sivertsen, Esperanza Díaz, Dan Pope, Rolv T. Lie, Anaite Díaz, John McCracken, Per Bakke, Byron Arana, Kirk R. Smith, Nigel Bruce

    Exposure to household wood smoke from cooking is a risk factor for chronic obstructive lung disease among women in developing countries. The Randomized Exposure Study of Pollution Indoors and Respiratory Effects (RESPIRE) is a randomized intervention trial evaluating the respiratory health effects of reducing indoor air pollution from open cooking fires. A total of 504 rural Mayan women in highland Guatemala aged 15–50 years, all using traditional indoor open fires, were randomized to either receive a chimney woodstove (plancha) or continue using the open fire. Assessments of chronic respiratory symptoms and lung function and individual measurements of carbon monoxide exposure were performed at baseline and every 6 months up to 18 months. Use of a plancha significantly reduced carbon monoxide exposure by 61.6%. For all respiratory symptoms, reductions in risk were observed in the plancha group during follow-up; the reduction was statistically significant for wheeze (relative risk = 0.42, 95% confidence interval: 0.25, 0.70). The number of respiratory symptoms reported by the women at each follow-up point was also significantly reduced by the plancha (odds ratio = 0.7, 95% confidence interval: 0.50, 0.97). However, no significant effects on lung function were found after 12–18 months. Reducing indoor air pollution from household biomass burning may relieve symptoms consistent with chronic respiratory tract irritation.

    Self-rated health among Mayan women participating in a randomised intervention trial reducing indoor air pollution in Guatemala

    by Esperanza Díaz, Nigel Bruce, Dan Pope, Anaité Díaz, Kirk R Smith, Tone Smith-Sivertsen

    Indoor air pollution (IAP) from solid fuels is a serious health problem in low-income countries that can be alleviated using improved stoves. Although women are the principal users, few studies have investigated the self-assessed impact of the stoves on their health and lives. This study was conducted in rural highland Guatemala, involving 89 intervention and 80 control Mayan Indian young women (mean 27.8 years, SD 7.2). Outcomes were assessed after approximately 18 months use of the new stove. Our objectives were to compare self-rated health and change in health among women participating in a randomised control trial comparing a chimney stove with an open fire, to describe impacts on women's daily lives and their perceptions of how reduced kitchen smoke affects their own and their children's health. On intention-to-treat analysis, 52.8% of intervention women reported improvement in health, compared to 23.8% of control women (p < 0.001). Among 84 intervention women who reported reduced kitchen smoke as an important change, 88% linked this to improvement in their own health, particularly for non-respiratory symptoms (for example eye discomfort, headache); 57% linked reduced smoke to improvement in their children's health, particularly sore eyes. Women's perception of their health was improved, but although smoke reduction was valued, this was linked mainly with alleviation of non-respiratory symptoms like eye discomfort and headache. More focus on such symptoms may help in promoting demand for improved stoves and cleaner fuels, but education about more severe consequences of IAP exposure is also required.


  • Eye discomfort, headache and back pain among Mayan Guatemalan women taking part in a randomised stove intervention trial

    by Esperanza Díaz, Tone Smith-Sivertsen, Dan Pope, Rolv T Lie, Anaite Díaz, John McCracken, Byron Arana, Kirk R Smith, Nigel Bruce

    Background: Indoor air pollution (IAP) from combustion of biomass fuels represents a global health problem, estimated to cause 1.6 million premature deaths annually. Aims: RESPIRE (Randomised Exposure Study of Pollution Indoors and Respiratory Effects) Guatemala is the first randomised controlled trial ever performed on health effects from solid fuel use. Its goal is to assess the effect of improved stoves (planchas) on exposure and health outcomes in a rural population reliant on wood fuel. Methods: Questions about symptoms were asked at baseline and periodically after the intervention, to an initial group of 504 women (259 randomly assigned to planchas (mean (standard deviation) age 27.4 (7.2) years) and 245 using traditional open fires (28.1 (7.1) years)). Levels of carbon monoxide (CO) in exhaled breath, a biomarker of recent exposure to air pollution from biomass combustion, were measured at each visit. In addition to reducing IAP levels, the plancha may also have a positive health effect by changing the working posture to an upright position. Results: A high prevalence of eye discomfort, headache and backache was found. The odds of having sore eyes and headache were substantially reduced in the plancha group relative to the group using open fires for the follow-up period (odds ratio (OR) 0.18, 95% confidence interval (CI) 0.11 to 0.29 and (OR) 0.63, 95% CI 0.42 to 0.94, respectively). Median CO in breath among women in the intervention trial was significantly lower than controls. Conclusion: In addition to reducing discomfort for women, tangible improvements in symptoms experienced by a substantial proportion of women may help to gain acceptance and wider use of planchas.
