A majority of pregnant women report LBPP. Parity, LBPP during a previous pregnancy, body mass index, a history of hypermobility, and amenorrhea are factors influencing the risk of developing LBPP during pregnancy.

Mammalian pregnancy is an intriguing immunological phenomenon where the semiallogeneic fetus is not rejected. Tolerance toward the fetus involves a number of mechanisms associated with modifications of the immune status of the mother. In this study, we strongly suggest a novel mechanism for fetal evasion of maternal immune attack, based on the engagement and down-regulation of the activating NK cell receptor NKG2D on PBMC by soluble MHC class I chain-related proteins A and B (collectively termed MIC). A similar immune escape pathway was previously described in tumors. We found that MIC mRNA was constitutively expressed by human placenta and could be up-regulated upon heat shock treatment. Our immunomorphologic studies showed that the MIC expression in placenta was restricted to the syncytiotrophoblast. Immunoelectron microscopy revealed a dual MIC expression in the syncytiotrophoblast: on the apical and basal cell membrane and in cytoplasmic vacuoles as MIC-loaded microvesicles/exosomes. Soluble MIC molecules were present at elevated levels in maternal blood throughout normal pregnancy and were released by placental explants in vitro. Simultaneously, the cell surface NKG2D expression on maternal PBMC was down-regulated compared with nonpregnant controls. The soluble MIC molecules in pregnancy serum were able to interact with NKG2D and down-regulate the receptor on PBMC from healthy donors, with the consequent inhibition of the NKG2D-dependent cytotoxic response. These findings suggest a new physiological mechanism of silencing the maternal immune system that promotes fetal allograft immune escape and supports the view of the placenta as an immunoregulatory organ.

Background:Intimate partner violence (IPV) is an important public health issue with severe adverse consequences. Population-based data on IPV from Muslim societies are scarce, and Pakistan is no exception. This study was conducted among women residing in urban Karachi, to estimate the prevalence and frequency of different forms of IPV and their associations with sociodemographic factors.Methods:This cross-sectional community-based study was conducted using a structured questionnaire developed by the World Health Organisation for research on violence. Community midwives conducted face-to-face interviews with 759 married women aged 25–60 years.Results:Self-reported past-year and lifetime prevalence of physical violence was 56.3 and 57.6%, respectively; the corresponding figures for sexual violence were 53.4% and 54.5%, and for psychological abuse were 81.8% and 83.6%. Violent incidents were mostly reported to have occurred on more than three occasions during the lifetime. Risk factors for physical violence related mainly to the husband, his low educational attainment, unskilled worker status, and five or more family members living in one household. For sexual violence, the risk factors were the respondent’s low educational attainment, low socioeconomic status of the family, and five or more family members in one household. For psychological violence, the risk factors were the husband being an unskilled worker and low socioeconomic status of the family.Conclusion:Repeated violence perpetrated by a husband towards his wife is an extremely common phenomenon in Karachi, Pakistan. Indifference to this type of violence against women stems from the attitude that IPV is a private matter, usually considered a justifiable response to misbehavior on the part of the wife. These findings point to serious violations of women’s rights and require the immediate attention of health professionals and policymakers.

BackgroundPakistan is a patriarchal society where men are the primary authority figures and women are subordinate. This has serious implications on women's and men's life prospects.ObjectiveThe aim was to explore current gender roles in urban Pakistan, how these are reproduced and maintained and influence men's and women's life circumstances.DesignFive focus group discussions were conducted, including 28 women representing employed, unemployed, educated and uneducated women from different socio-economic strata. Manifest and latent content analyses were applied.FindingsTwo major themes emerged during analysis: ‘Reiteration of gender roles’ and ‘Agents of change’. The first theme included perceptions of traditional gender roles and how these preserve women's subordination. The power gradient, with men holding a superior position in relation to women, distinctive features in the culture and the role of the extended family were considered to interact to suppress women. The second theme included agents of change, where the role of education was prominent as well as the role of mass media. It was further emphasised that the younger generation was more positive to modernisation of gender roles than the elder generation.ConclusionsThis study reveals serious gender inequalities and human rights violations against women in the Pakistani society. The unequal gender roles were perceived as static and enforced by structures imbedded in society. Women routinely faced serious restrictions and limitations of autonomy. However, attainment of higher levels of education especially not only for women but also for men was viewed as an agent towards change. Furthermore, mass media was perceived as having a positive role to play in supporting women's empowerment.

BackgroundThere are good opportunities in Sweden for health promotion targeting expectant parents and parents of young children, as almost all are reached by antenatal and child health care. In 2005, a multisectoral child health promotion programme (the Salut Programme) was launched to further strengthen such efforts.MethodsBetween June and December 2010 twenty-four in-depth interviews were conducted separately with first-time mothers and fathers when their child had reached 18 months of age. The aim was to explore their experiences of health promotion and lifestyle change during pregnancy and early parenthood. Qualitative manifest and latent content analysis was applied.ResultsParents reported undertaking lifestyle changes to secure the health of the fetus during pregnancy, and in early parenthood to create a health-promoting environment for the child. Both women and men portrayed themselves as highly receptive to health messages regarding the effect of their lifestyle on fetal health, and they frequently mentioned risks related to tobacco and alcohol, as well as toxins and infectious agents in specific foods. However, health promotion strategies in pregnancy and early parenthood did not seem to influence parents to make lifestyle change primarily to promote their own health; a healthy lifestyle was simply perceived as 'common knowledge'. Although trust in health care was generally high, both women and men described some resistance to what they saw as preaching, or very directive counselling about healthy living and the lack of a holistic approach from health care providers. They also reported insufficient engagement with fathers in antenatal care and child health care.ConclusionPerceptions about risks to the offspring's health appear to be the primary driving force for lifestyle change during pregnancy and early parenthood. However, as parents' motivation to prioritise their own health per se seems to be low during this period, future health promoting programmes need to take this into account. A more gender equal provision of health promotion to parents might increase men's involvement in lifestyle change. Furthermore, parents' ranking of major lifestyle risks to the fetus may not sufficiently reflect those that constitute greatest public health concern, an area for further study.
