BackgroundChanges over time in self-rated health (SRH) are increasingly documented during the current economic crisis, though whether these are due to selection, causation, or methodological artefacts is unclear. This study accordingly investigates changes in SRH, and social inequalities in these changes, before and during the economic crisis in 23 European countries.MethodsWe used balanced panel data, 2005–2011, from the European Union Statistics on Income and Living Conditions (EU-SILC). We included the working-age population (25–60 years old) living in 23 European countries. The data cover 65,618 respondents, 2005–2007 (pre-recession cohort), and 43,188 respondents, 2008–2011 (recession cohort). The data analyses used mixed-effects ordinal logistic regression models considering the degree of recession (i.e., pre, mild, and severe).ResultsIndividual-level changes in SRH over time indicted a stable trend during the pre-recession period, while a significant increasing trend in fair and poor SRH was found in the mild- and severe-recession cohorts. Micro-level demographic and socio-economic status (SES) factors (i.e., age, gender, education, and transitions to employment/unemployment), and macro-level factors such as welfare generosity are significantly associated with SRH trends across the degrees of recession.ConclusionsThe current economic crisis accounts for an increasing trend in fair and poor SRH among the general working-age population of Europe. Despite the general SES inequalities in SRH, the health of vulnerable groups has been affected the same way before and during the current recession.Electronic supplementary materialThe online version of this article (doi:10.1186/s12939-015-0290-8) contains supplementary material, which is available to authorized users.

Utilization rates of specialist mental healthcare are lower among immigrants than Norwegians. Immigrants from Poland, Somalia, Sri Lanka, and Vietnam, had generally quite low rates, while immigrants from Iran had high utilization rates. The findings suggest that specialist mental healthcare in Norway is underutilized among considerable parts of the immigrant population.

Mental health problems have been regarded as one of the main public health challenges of immigrants in several countries. Understanding and generating research-based knowledge on immigrant health problems is highly relevant for planning preventive interventions, as well as guiding social and policy actions. This review aims to map the available knowledge on immigrants' mental health status and its associated risk factors in Norway. The reviewed literature about mental health problems among immigrant populations in Norway was found through databases, such as PUBMED, EMBASE, PsychINFO and MEDLINE. About 41 peer-reviewed original articles published since 1990s were included. In the majority of the studies, the immigrant populations, specifically adult immigrants from low and middle income countries, have been found with a higher degree of mental health problems compared to Norwegians and the general population. Increased risk for mental illness is primarily linked to a higher risk for acculturative stress, poor social support, deprived socioeconomic conditions, multiple negative life events, experiences of discrimination and traumatic pre-migration experiences. However, research in this field has been confronted by a number of gaps and methodological challenges. The available knowledge indicates a need for preventive interventions. Correspondingly, it strongly recommends a comprehensive research program that addresses gaps and methodological challenges.

The aim of the study was to assess prevalence and factors associated with binge drinking, cannabis use and tobacco use among ethnic Norwegians and ethnic minority adolescents in Oslo. We used data from a school-based cross-sectional survey of adolescents in junior- and senior high schools in Oslo, Norway. The participants were 10,934 adolescents aged 14-17 years, and just over half were females. The sample was comprised of 73.2 % ethnic Norwegian adolescents, 9.8 % 1st generation immigrants, and 17 % 2nd generation adolescents from Europe, the US, the Middle East, Asia and Africa. Logistic regression models were applied for the data analyses. Age, gender, religion, parental education, parent-adolescent relationships, depressive symptoms and loneliness were covariates in the regression models. Ethnic Norwegian adolescents reported the highest prevalence of binge drinking (16.1 %), whereas the lowest prevalence was found among 2nd generation adolescents from Asia (2.9 %). Likewise, the past-year prevalence for cannabis use ranged from 10.6 % among 2nd generation Europeans and those from the US to 3.7 % among 2nd generation Asians. For daily tobacco use, the prevalence ranged from 12.9 % among 2nd generation Europeans and the US to 5.1 % among 2nd generation Asians. Ethnicity, age, gender, religion, parental education, and parent-adolescent relationships and mental health status were significantly associated with binge drinking, cannabis and tobacco use. These factors partly explained the observed differences between ethnic Norwegians and ethnic minority adolescents in the current study. There are significant differences in substance use behaviors between ethnic Norwegian and immigrant youth. Factors like age, gender, religion, parental education and relationships and mental health status might influence the relationship between ethnicity and substance abuse. The findings have implications for planning selective- as well as universal prevention interventions.

Background: Malaria is a major public health problem in the world in general and developing countries in particular, causing an estimated 1-2 million deaths per year, an annual incidence of 300-500 million clinical cases and more than 2 billion people are at risk of infection from it. But it is also becoming more difficult to treat malaria due to the increasing drug resistance. Therefore, the need for alternative drugs is acute. Objective: This study aims at investigating the in vivo antiplasmodial activity of extracts of the roots and area parts from traditionally used medicinal plant, named Asparagus africanus (Liliaceae). Methods: A rodent malaria parasite, Plasmodium berghei, which was maintained at the Ethiopian Health and Nutrition Research Institute (EHNRI) laboratory, was inoculated into Swiss albino mice. The mice were infected with 1x10 7 parasites intraperitoneally. The extracts were administered by an intra gastric tube daily for four days starting from the day of parasite inoculation. The control groups received the same amount of solvent (vehicle) used to suspend each dose of the herbal drug. Chloroquine was used as a standard drug, and was administered through the same route. Results: Extracts from the roots and aerial parts of A.africanus were observed to inhibit Plasomodium berghei parasitaemia in the Swiss albino mice by 46.1% and 40.7% respectively. Conclusion: The study could partly confirm the claim in Ethiopian traditional medicine that the plant has therapeutic values in human malaria. There is, thus, the need to initiate further in-depth investigation by using different experimental models.
