The effects of radiofrequency exposure on cognition: A systematic review and meta-analysis of human observational studies.

BACKGROUND: We aimed to assess evidence of long-term effects of exposure to radiofrequency (RF) electromagnetic fields (EMF) on indicators of cognition, including domains of learning and memory, executive function, complex attention, language, perceptual motor ability and social cognition, and of an exposure-response relationship between RF-EMF and cognition. METHODS: We searched PubMed, Embase, PsycInfo and the EMF-Portal on September 30, 2022 without limiting by date or language of publication. We included cohort or case-control studies that evaluated the effects of RF exposure on cognitive function in one or more of the cognitive domains. Studies were rated for risk of bias using the OHAT tool and synthesised using fixed effects meta-analysis. We assessed the certainty of the evidence using the GRADE approach and considered modification by OHAT for assessing evidence of exposures. RESULTS: We included 5 studies that reported analyses of data from 4 cohorts with 4639 participants consisting of 2808 adults and 1831 children across three countries (Australia, Singapore and Switzerland) conducted between 2006 and 2017. The main source of RF-EMF exposure was mobile (cell) phone use measured as calls per week or minutes per day. For mobile phone use in children, two studies (615 participants) that compared an increase in mobile phone use to a decrease or no change were included in meta-analyses. Learning and memory. There was little effect on accuracy (mean difference, MD -0.03; 95% CI -0.07 to 0.02) or response time (MD -0.01; 95% CI -0.04 to 0.02) on the one-back memory task; and accuracy (MD -0.02; 95%CI -0.04 to 0.00) or response time (MD -0.01; 95%CI -0.04 to 0.03) on the one card learning task (low certainty evidence for all outcomes). Executive function. There was little to no effect on the Stroop test for the time ratio ((B-A)/A) response (MD 0.02; 95% CI -0.01 to 0.04, very low certainty) or the time ratio ((D-C)/C) response (MD 0.00; 95% CI -0.06 to 0.05, very low certainty), with both tests measuring susceptibility to interference effects. Complex attention. There was little to no effect on detection task accuracy (MD 0.02; 95% CI -0.04 to 0.08), or response time (MD 0.02;95% CI 0.01 to 0.03), and little to no effect on identification task accuracy (MD 0.00; 95% CI -0.04 to 0.05) or response time (MD 0.00;95% CI -0.01 to 0.02) (low certainty evidence for all outcomes). No other cognitive domains were investigated in children. A single study among elderly people provided very low certainty evidence that more frequent mobile phone use may have little to no effect on the odds of a decline in global cognitive function (odds ratio, OR 0.81; 95% CI 0.42 to 1.58, 649 participants) or a decline in executive function (OR 1.07; 95% CI 0.37 to 3.05, 146 participants), and may lead to a small, probably unimportant, reduction in the odds of a decline in complex attention (OR 0.67;95%CI 0.27 to 1.68, 159 participants) and a decline in learning and memory (OR 0.75; 95% CI 0.29 to 1.99, 159 participants). An exposure-response relationship was not identified for any of the cognitive outcomes. DISCUSSION: This systematic review and meta-analysis found only a few studies that provided very low to low certainty evidence of little to no association between RF-EMF exposure and learning and memory, executive function and complex attention. None of the studies among children reported on global cognitive function or other domains of cognition. Only one study reported a lack of an effect for all domains in elderly persons but this was of very low certainty evidence. Further studies are needed to address all types of populations, exposures and cognitive outcomes, particularly studies investigating environmental and occupational exposure in adults. Future studies also need to address uncertainties in the assessment of exposure and standardise testing of specific domains of cognitive function to enable synthesis across studies and increase the certainty of the evidence.

Engaging culturally diverse fathers in maternal and family healthcare: Experiences and perspectives of healthcare professionals.

ISSUE ADDRESSED: Australian maternal, family and child services increasingly espouse the value of being 'father-inclusive'. However, fathers report feeling excluded or marginalised during healthcare visits with their partners/infants, and experience barriers to engaging in perinatal healthcare at the community, individual and healthcare service level. These barriers may be amplified in men who are members of minority groups, such as those from culturally and linguistically diverse (CALD) backgrounds. METHODS: This research investigated healthcare professionals' perceptions and experiences of providing perinatal health services to families from CALD backgrounds. Semi-structured interviews were held with healthcare professionals from multiple disciplinary backgrounds providing services to families in the perinatal period. Interviews were audio recorded, transcribed and analysed thematically to identify key themes and sub-themes. RESULTS: Ten healthcare professionals were interviewed. Participants acknowledged that inclusion of fathers in care is important as involvement enables fathers to support their pregnant partners and children, manage their own mental health, and helps to transform harmful gender roles. CONCLUSIONS: Overall, healthcare professionals are willing to include culturally diverse fathers. However, the ability of culturally diverse families to engage with healthcare services is impacted by the cultural competency of the services. So what? Healthcare delivered during pregnancy, childbirth and postpartum year may be improved by adopting a whole-family approach, which considers the needs and perspectives of fathers and partners. However, particular attention is needed to ensure healthcare policies and practices are culturally competent to meet the needs of fathers from culturally diverse backgrounds.

Epidemiology of eczema in South-Eastern Australia.

BACKGROUND/OBJECTIVES: Eczema is a common chronic debilitating skin condition in childhood. Data on the epidemiology and natural history of eczema across the life course are lacking. This analysis aimed to describe these epidemiological features in Australian children and adults. METHODS: Data collected on eczema from four Australian cohort studies were analysed: namely HealthNuts, Melbourne Atopic Cohort Study (MACS), Tasmanian Longitudinal Health Study (TAHS) and the Australian arm of the European Community Respiratory Health Survey (ECRHS). RESULTS: Among children aged under 6 years, 28.8%-35.6% have ever-had eczema, and 16.7%-26.6% had 'current eczema'. Among those aged 6-12 years, 14.6%-24.7% had 'current eczema' with 12.0%-18.5% of those at ages of 6 and 10 years classified as having moderate-to-severe eczema according to the Scoring of Atopic Dermatitis (SCORAD) index. In adults, the prevalence of 'eczema ever' ranged between 13.8% and 48.4%. The 12-month period prevalence of eczema was 15.1% at age 18, while current eczema was 8.5% at an average age of 51, and 8.8% at an average age 53 years. Eczema was more common among young boys, but this difference became non-significant for older children and early adolescents. In contrast, eczema was more common for adult women than men. CONCLUSIONS: Eczema is common both in children and adults. The proportion of severe eczema in children was substantial.

Mobile phone carrying locations and risk perception of men: A cross-sectional study.

Little was known about the relationship between carrying mobile phone handsets by men and their risk perception of radiofrequency-electromagnetic field (RF-EMF) exposure due to carrying handsets close to the body. This study aimed to determine where men usually carried their handsets and to assess the relationship to risk perception of RF-EMF. Participants completed a self-administered questionnaire about mobile phone use, handset carrying locations, and levels of risk perception to RF-EMF. Data were analysed using linear regression models to examine if risk perception differed by mobile phone carrying location. The participants were 356 men, aged 18-72 years. They owned a mobile phone for 2-29 years, with over three quarters (78.7%) having a mobile phone for over 20 years. The most common locations that men kept their handsets when they were 'indoors' were: on a table/desk (54.0%) or in close contact with the body (34.7%). When outside, 54.0% of men kept the handset in the front trouser pocket. While making or receiving calls, 85.0% of men held their mobile phone handset against the head and 15.0% either used earphones or loudspeaker. Men who carried their handset in close contact with the body perceived higher risks from RF-EMF exposure compared to those who kept it away from the body (p<0.01). A substantial proportion of men carried their mobile phone handsets in close proximity to reproductive organs i.e. front pocket of trousers (46.5%). Men who kept their handset with the hand (p < .05), and those who placed it in the T-shirt pocket (p < .05), while the phone was not in use, were more likely to perceive health risks from their behaviour, compared to those who kept it away from the body. However, whether this indicates a causal relationship, remains open.

Fathers' involvement in perinatal healthcare in Australia: experiences and reflections of Ethiopian-Australian men and women.

BACKGROUND: Family-centred maternity care models include the expectation that fathers prepare for and attend the birth. In Australia over 20% of the population is from a culturally and linguistically diverse background. Public policies espouse culturally competent healthcare. Little is known about the experiences of perinatal health care of men from culturally and linguistically diverse (CALD) communities living in high income countries. The aim was to understand the experiences, attitudes and beliefs about father's inclusion in perinatal healthcare, from the growing, and recently settled community of Ethiopian families living in Australia. METHODS: A qualitative study using semi-structured individual interviews with Ethiopian-Australian men and women who had experienced Australian maternity care and were sampled for diversity of time since migration, and parity. Interviews were in English, audio-recorded, transcribed and then analysed thematically. RESULTS: Participants were seven women and six men all born in Ethiopia, including two couples. Key themes included: the loss of extended family through migration, new roles for both parents and the need to establish 'family-like' relationships with friendship groups in Australia. There was a willingness to involve male partners in the Ethiopian community in Australia, although it was recognised as a cultural change. Experiences of male partner involvement were mixed among healthcare types, with men attending Maternal and Child Health (MCH) appointments less frequently than antenatal (ANC) appointments. CONCLUSIONS: Results suggests men may be missing out on the education provided during antenatal appointments and may benefit from an alternative. There were not universally high levels of cultural competency among healthcare professionals, with further training still required. Commitment to paid employment remains a barrier to men's involvement, suggesting that flexible working conditions and increased paternity leave would support their involvement. Alternatively services could utilise flexible delivery methods such as phone and zoom to include fathers.

Wi-fi related radiofrequency electromagnetic fields (RF-EMF): a pilot experimental study of personal exposure and risk perception.

The impact of providing people with an objectively measured personal radiofrequency electromagnetic fields (RF-EMF) exposure information on the risk perception of people is not well understood. We conducted an experimental study, among three groups of participants, to investigate the risk perception of people towards RF-EMF from Wi-Fi sources (ISM 2.4 GHz) by providing participants with either basic text, precautionary information, or a summary of their personal RF-EMF exposure measurement levels. Participants provided with personal RF-EMF exposure measurement information were more confident in protecting themselves from RF-EMF exposure, compared to those provided with only basic information. Nonetheless, neither the exposure perception nor the risk perception of people to Wi-Fi related RF-EMF differed by the type of information provided. The measured Wi-Fi signal levels were far below international exposure limits. Furthermore, self-rated levels of personal RF-EMF exposure perception were not associated with objectively measured RF-EMF exposure levels. Providing people with objectively measured information may help them build confidence in protecting themselves from Wi-Fi related RF-EMF exposure.

Markers of Cardiovascular Disease among Adults Exposed to Smoke from the Hazelwood Coal Mine Fire.

Little research has examined the effects of high concentration, medium-duration smoke exposure on cardiovascular health. We investigated whether six weeks of exposure to smoke from the 2014 Hazelwood coal mine fire in Victoria (Australia), was associated with long-term clinical or subclinical cardiovascular disease approximately four years later, in adult residents of the towns of Morwell (exposed, n = 336) and Sale (unexposed, n = 162). The primary outcome was serum high sensitivity (hs) C-reactive protein (CRP). Blood pressure, electrocardiogram, flow mediated dilatation and serum levels of hs-troponin, N-terminal pro B-type natriuretic peptide and lipids were secondary outcomes. There was no significant difference in weighted median hsCRP levels between exposed and unexposed participants (1.9 mg/L vs. 1.6 mg/L, p = 0.273). Other outcomes were comparable between the groups. hsCRP was associated in a predictable manner with current smoking, obesity and use of lipid-lowering therapy. Four years after a 6-week coal mine fire, this study found no association between smoke exposure and markers of clinical or subclinical cardiovascular disease in exposed adults.

Male partner involvement in birth preparedness, complication readiness and obstetric emergencies in Sub-Saharan Africa: a scoping review.

BACKGROUND: Maternal mortality remains a pressing concern across Sub-Sahara Africa. The 'Three Delays Model' suggests that maternal deaths are a consequence of delays in: seeking care, reaching medical care and receiving care. Birth Preparedness and Complication Readiness (BPCR) refers to a plan organised during pregnancy in preparation for a normal birth and in case of complications. Male partners in many Sub-Saharan African communities could play a pivotal role in a woman's ability to prepare for birth and respond to obstetric complications. This review aimed identify: the extent and quality of research performed on the topic of male partner involvement in BPCR in Sub-Saharan Africa; the degree to which populations and geographic areas are represented; how male partner involvement has been conceptualized; how male partners response to obstetric complications has been conceptualised; how the variation in male partners involvement has been measured and if any interventions have been performed. METHODS: In this scoping review, articles were identified through a systematic search of databases MEDLINE, EMBASE and Maternity and Infant Care and a manual scan of relevant papers, journals and websites. All authors contributed to the screening process and a quality assessment using the Kmet checklist. The PRISMA checking list for Scoping Reviews was used to guide the search, data charting and reporting of the review The protocol was registered with PROSPERO (ID: CRD42019126263). RESULTS: Thirty-five articles met inclusion criteria, reporting: 13 qualitative, 13 cross-sectional, 5 mixed method and 4 intervention studies. Data were contributed by approximately 14,550 participants (numbers were not always reported for focus groups) including: women who were pregnant or who had experienced pregnancy or childbirth within the previous 3 years, their male partners and key informants such as health workers and community leaders. CONCLUSIONS: The diversity of study designs, aims and source countries in this body of literature reflects an emerging stage of research; as a result, the review yielded strong evidence in some areas and gaps in others. Male partner's involvement in BPCR and responding to obstetric emergencies can be conceptualised as being centrally involved in responding to complications and having some role in preparing for birth through their position in the chain of decisions and provision of logistic support. However, their knowledge of pregnancy complications and level of preparation for birth is low, suggesting they are making decisions without being fully informed. There is limited evidence on interventions to improve their knowledge. Future research efforts should be focused on producing standardised, culturally appropriate, higher level evidence.

Radiofrequency electromagnetic field exposure assessment: a pilot study on mobile phone signal strength and transmitted power levels.

In many epidemiological studies mobile phone use has been used as an exposure proxy for radiofrequency electromagnetic field (RF-EMF) exposure. However, RF-EMF exposure assessment from mobile phone use is prone to measurement errors limiting epidemiological research. An often-overlooked aspect is received signal strength levels from base stations and its correlation with mobile phone transmit (Tx) power. The Qualipoc android phone is a tool that provides information on both signal strength and Tx power. The phone produces simultaneous measurements of Received Signal Strength Indicator (RSSI), Reference Signal Received Power (RSRP), Received Signal Code Power (RSCP), and Tx power on the 3G and 4G networks. Measurements taken in the greater Melbourne area found a wide range of signal strength levels. The correlations between multiple signal strength indicators and Tx power were assessed with strong negative correlations found for 3G and 4G data technologies (3G RSSI -0.93, RSCP -0.93; 4G RSSI -0.85, RSRP -0.87). Variations in Tx power over categorical levels of signal strength were quantified and showed large increases in Tx power as signal level decreased. Future epidemiological studies should control for signal strength or factors influencing signal strength to reduce RF-EMF exposure measurement error.

Uncertainty Analysis of Mobile Phone Use and Its Effect on Cognitive Function: The Application of Monte Carlo Simulation in a Cohort of Australian Primary School Children.

Previous epidemiological studies on health effects of radiation exposure from mobile phones have produced inconsistent results. This may be due to experimental difficulties and various sources of uncertainty, such as statistical variability, measurement errors, and model uncertainty. An analytical technique known as the Monte Carlo simulation provides an additional approach to analysis by addressing uncertainty in model inputs using error probability distributions, rather than point-source data. The aim of this investigation was to demonstrate using Monte Carlo simulation of data from the ExPOSURE (Examination of Psychological Outcomes in Students using Radiofrequency dEvices) study to quantify uncertainty in the output of the model. Data were collected twice, approximately one year apart (between 2011 and 2013) for 412 primary school participants in Australia. Monte Carlo simulation was used to estimate output uncertainty in the model due to uncertainties in the call exposure data. Multiple linear regression models evaluated associations between mobile phone calls with cognitive function and found weak evidence of an association. Similar to previous longitudinal analysis, associations were found for the Go/No Go and Groton maze learning tasks, and a Stroop time ratio. However, with the introduction of uncertainty analysis, the results were closer to the null hypothesis.

Radiofrequency electromagnetic field exposure and risk perception: A pilot experimental study.

BACKGROUND: Exposure to far-field radiofrequency electromagnetic fields (RF-EMF) has raised public concerns in recent decades. However, it is not known if individuals' perception towards the health risks of RF-EMF is dependent on their knowledge of the objectively measured personal RF-EMF exposure levels. OBJECTIVES: This pilot study aimed to demonstrate the feasibility of objectively measuring personal RF-EMF exposure from mobile phone base stations (MPBS) and to determine if the risk perception of people to the potential health risk of exposure to RF-EMF from MPBS is dependent on their knowledge of personal RF-EMF exposure levels. DESIGN: An experimental study was conducted in 383 adults, recruited in Melbourne, Australia. Participants were randomized to one of the three groups: 1) basic information group who were provided with basic information about RF-EMF to read prior to completing a risk perception assessment questionnaire; 2) precautionary group who were provided with an information pack which included precautionary messages; and 3) personal exposure measurement group who were provided with a summary of their quantitative RF-EMF exposure from MPBS. The same basic information about RF-EMF was also given to the precautionary and personal exposure measurement groups. RESULTS: Participants had a mean (±â€¯SD) age of 36.9 ±â€¯12.5 years; 66.7% were women. Overall, 44.1% had noticed an MPBS in their neighbourhood. The mean (SD) values (from 1 to 7) for risk perceptions to RF-EMF from MPBS were 4.02 (1.67) for basic information, 3.82 (1.62) for precautionary messages, and 3.97 (1.72) for the personal exposure measurement groups. These differences were not statistically significant. Nevertheless, the personal exposure measurement group were more confident that they could protect themselves from RF-EMF than the precautionary or basic information groups. CONCLUSION: Our findings suggest that providing people with personal RF-EMF exposure measurements may not affect their perceived risk from MPBS, but increase their confidence in protecting themselves.

Estimating transmitted power density from mobile phone: an epidemiological pilot study with a software modified phone.

The aims of this study were to evaluate the weekly and annual cumulative radiofrequency-electromagnetic field (RF-EMF) exposure attributed to mobile phone (MP) use, and assess whether a novel app (Quanta Monitor™) could be employed in a small human sample to characterise the RF-EMF exposures associated with the use of MPs. Ten participants provided their two months' daily objective data on their MP exposures (i.e. transmitted and received power densities) attributed to different modes of MP usage such as cellular calls, cellular data and Wi-Fi. The results demonstrated that total transmitted power density (cellular phone calls, data and Wi-Fi surfing) could be many orders of magnitude higher than that from the total received power density. Of the total transmitted power density, cellular data use contributed the largest portion. Our study showed that Quanta Monitor™ could be employed in prospective assessment of exposures to MPs in epidemiological studies.

Personal Exposure to Radio Frequency Electromagnetic Fields among Australian Adults.

The measurement of personal exposure to radiofrequency electromagnetic fields (RF-EMFs) is important for epidemiological studies. RF-EMF exposure can be measured using personal exposimeters that register RF-EMFs over a wide range of frequency bands. This study aimed to measure and describe personal RF-EMF exposure levels from a wide range of frequency bands. Measurements were recorded from 63 participants over an average of 27.4 (±4.5) hours. RF-EMF exposure levels were computed for each frequency band, as well as from downlink (RF from mobile phone base station), uplink (RF from mobile phone handsets), broadcast, and Wi-Fi. Participants had a mean (±SD) age of 36.9 ± 12.5 years; 66.7% were women; and almost all (98.2%) from urban areas. A Wi-Fi router at home was reported by 61 participants (96.8%), with 38 (61.2%) having a Wi-Fi enabled smart TV. Overall, 26 (41.3%) participants had noticed the existence of a mobile phone base station in their neighborhood. On average, participants estimated the distance between the base station and their usual residence to be about 500 m. The median personal RF-EMF exposure was 208 mV/m. Downlink contributed 40.4% of the total RF-EMF exposure, followed by broadcast (22.4%), uplink (17.3%), and Wi-Fi (15.9%). RF-EMF exposure levels on weekdays were higher than weekends (p < 0.05). Downlink and broadcast are the main contributors to total RF-EMF personal exposure. Personal RF-EMF exposure levels vary according to day of the week and time of day.

Is exposure to personal music players a confounder in adolescent mobile phone use and hearing health studies?

OBJECTIVE: This study was performed to determine whether exposure to personal music players (PMPs) in the immediate morning prior to hearing testing confounds the association between mobile phone use and hearing thresholds of adolescents. DESIGN: In this cohort study of cognitive function in year 7 students (median age 13 years, range 11-14), information regarding the weekly use of mobile phones and the use of PMPs was assessed by a questionnaire. Pure-tone audiometry was used to establish hearing thresholds for all participants. RESULTS: Among a cohort of 317 adolescents (60.9% females), 130 were unexposed to PMP use while 33 were exposed to PMP use in the morning prior to hearing testing. No statistically significant difference in hearing threshold shifts was found between adolescents who were and were not exposed to PMP use prior to hearing testing. Likewise, the difference in the use of mobile phones according to the PMP use status was not statistically significant. CONCLUSION: Exposure to PMPs prior to hearing testing did not introduce confounding in the present study of mobile phone use and hearing loss among adolescents.

Male partner attendance at antenatal care and adherence to antenatal care guidelines: secondary analysis of 2011 Ethiopian demographic and health survey data.

BACKGROUND: Complications during pregnancy, childbirth and the postpartum period present a significant and complex public health problem in low income countries such as Ethiopia. One strategy endorsed by the World Health Organisation (WHO) to improve maternal and child health outcomes is to encourage male partner involvement in pregnancy care. This research aimed to explore the relationships between 1) male attendance at antenatal care and 2) socio-economic and women's empowerment factors and adherence to focused antenatal care guidelines among women receiving care in Ethiopia. METHODS: Secondary analysis of 2011 Ethiopian Demographic and Health Survey (DHS) data. A sub-sample of couples with a child aged 0-2 years old, for whom women attended at least one antenatal care (ANC) appointment was selected. Predictor variables on socio-economic position, demographic and women's empowerment factors, and male attendance at antenatal care were identified. Six outcome variables were constructed to indicate whether or not women: commenced ANC in the first trimester, attended at least four ANC appointments, received a urine test, received a blood test, were counselled on potential complications during pregnancy and met these focused antenatal care guidelines. Binary logistic regression was performed to estimate the relationship between the predictor and outcome variables. RESULTS: After controlling for other factors, women whose partners attended ANC were significantly more likely to receive urine and blood tests and be counselled about pregnancy complications compared to women who attended alone. Male attendance was not associated with women commencing care in the first trimester or attending at least four appointments. Although more women whose male partners had attended appointments received all recommended components of ANC than those who attended alone, this association was not significant. CONCLUSIONS: The results revealed some benefits and did not detect harms from including male partners in focused antenatal care. Including men may require changes to maternal healthcare systems and training of healthcare workers, to adopt 'father inclusive' practices. Given the limited research in this area, large population studies including the DHS routinely carried out in Ethiopia could enhance knowledge by including more detailed indicators of male involvement in pregnancy, maternal and child healthcare and early child development.

Radiofrequency Electromagnetic Radiation and Memory Performance: Sources of Uncertainty in Epidemiological Cohort Studies.

Uncertainty in experimental studies of exposure to radiation from mobile phones has in the past only been framed within the context of statistical variability. It is now becoming more apparent to researchers that epistemic or reducible uncertainties can also affect the total error in results. These uncertainties are derived from a wide range of sources including human error, such as data transcription, model structure, measurement and linguistic errors in communication. The issue of epistemic uncertainty is reviewed and interpreted in the context of the MoRPhEUS, ExPOSURE and HERMES cohort studies which investigate the effect of radiofrequency electromagnetic radiation from mobile phones on memory performance. Research into this field has found inconsistent results due to limitations from a range of epistemic sources. Potential analytic approaches are suggested based on quantification of epistemic error using Monte Carlo simulation. It is recommended that future studies investigating the relationship between radiofrequency electromagnetic radiation and memory performance pay more attention to treatment of epistemic uncertainties as well as further research into improving exposure assessment. Use of directed acyclic graphs is also encouraged to display the assumed covariate relationship.

Vasomotor symptoms are associated with depressive symptoms in community-dwelling older women.

OBJECTIVE: To assess the prevalence of, and factors associated with, moderate-to-severe depressive symptoms in community-dwelling older Australian women. METHODS: A questionnaire-based, cross-sectional study was conducted amongst community-dwelling older women. Participants were recruited between April and August 2014 from a national database based on the electoral roll. Depressive symptoms were assessed by the Beck Depression Inventory-II (BDI-II) tool. Vasomotor symptoms (VMS), vulvovaginal atrophy (VVA), and pelvic floor symptoms were assessed using validated questionnaires. Women were provided a comprehensive list of psychotropic medications (antidepressants, benzodiazepines, antipsychotics, and mood stabilizers) to identify their use over the preceding month. RESULTS: In all, 1,534 women completed the BDI-II. Overall, 34.2% (95% confidence interval [CI] 31.8%-36.7%) of women had VMS, 6.3% (95% CI 5.2%-7.7%) had moderate-to-severe depressive symptoms (BDI-II score ≥20), 26.8% (95% CI 24.6%-29.1%) had used any psychotropic medication in the previous month, and 17.5% (95%CI: 15.6-19.5%) had taken an antidepressant.Moderate-to-severe depressive symptoms were more common among women using antidepressants compared with nonusers (16.6% vs 4.3%; P < 0.001). Obesity (adjusted odds ratio [AOR] 2.18, 95% CI 1.17-4.04), living in financially insecure housing (AOR 3.84, 95% CI 2.08-8.08), being a caregiver to another person (AOR 2.39, 95% CI 1.36-4.19), being a smoker (AOR 2.28, 95% CI 1.12-4.66), having VMS (AOR 1.67, 95% CI 1.03-2.62), having pelvic floor dysfunction (AOR 1.78, 95% CI 1.08-2.94), and having vaginal dryness during intercourse (AOR 1.84, 95% CI 1.06-3.22, P < 0.05) were positively and independently associated with moderate-to-severe depressive symptoms. Being currently partnered (AOR 0.57, 95% CI 0.33-0.97) and employed (AOR 0.38, 95% CI 0.16-0.92) were associated with a lower likelihood of depressive symptoms. CONCLUSIONS: In older women, depressive symptoms are common and are associated with social and financial insecurity, and with VMS.

Trends and causes of maternal mortality in Ethiopia during 1990-2013: findings from the Global Burden of Diseases study 2013.

BACKGROUND: Maternal mortality is noticeably high in sub-Saharan African countries including Ethiopia. Continuous nationwide systematic evaluation and assessment of the problem helps to design appropriate policy and strategy in Ethiopia. This study aimed to investigate the trends and causes of maternal mortality in Ethiopia between 1990 and 2013. METHODS: We used the Global Burden of Diseases and Risk factors (GBD) Study 2013 data that was collected from multiple sources at national and subnational levels. Spatio-temporal Gaussian Process Regression (ST-GPR) was applied to generate best estimates of maternal mortality with 95% Uncertainty Intervals (UI). Causes of death were measured using Cause of Death Ensemble modelling (CODEm). The modified UNAIDS EPP/SPECTRUM suite model was used to estimate HIV related maternal deaths. RESULTS: In Ethiopia, a total of 16,740 (95% UI: 14,197, 19,271) maternal deaths occurred in 1990 whereas there were 15,234 (95% UI: 11,378, 19,871) maternal deaths occurred in 2013. This finding shows that Maternal Mortality Ratio (MMR) in Ethiopia was still high in the study period. There was a minimal but insignificant change of MMR over the last 23 years. The results revealed Ethiopia is below the target of Millennium Development Goals (MGDs) related to MMR. The top five causes of maternal mortality in 2013 were other direct maternal causes such as complications of anaesthesia, embolism (air, amniotic fluid, and blood clot), and the condition of peripartum cardiomyopathy (25.7%), complications of abortions (19.6%), maternal haemorrhage (12.2%), hypertensive disorders (10.3%), and maternal sepsis and other maternal infections such as influenza, malaria, tuberculosis, and hepatitis (9.6%). Most of the maternal mortality happened during the postpartum period and majority of the deaths occurred at the age group of 20-29 years. Overall trend showed that there was a decline from 708 per 100,000 live births in 1990 to 497 per 100,000 in 2013. The annual rate of change over these years was -1.6 (95% UI: -2.8 to -0.3). CONCLUSION: The findings of the study highlight the need for comprehensive efforts using multisectoral collaborations from stakeholders for reducing maternal mortality in Ethiopia. It is worthwhile for policies to focus on postpartum period.

Hypoactive sexual desire dysfunction in community-dwelling older women.

OBJECTIVE: To determine the prevalence of hypoactive sexual desire dysfunction (HSDD) and its associated factors in women aged 65 to 79 years. METHODS: A questionnaire-based, cross-sectional study was conducted amongst community-dwelling older women. Participants were recruited between April and August 2014 from a national database based on electoral rolls. Sexual function and sexual distress were assessed by the Female Sexual Function Index and the Female Sexual Distress Scale-Revised, respectively. HSDD was defined as the presence of both low sexual desire and sexually related personal distress. RESULTS: The mean ±â€ŠSD age of the 1,548 women was 71 ±â€Š3.4 years and 52.6% were partnered. Among the participants, 88.0% (95% confidence interval [CI], 86.3%-89.6%) had low sexual desire, 15.5% (95% CI, 13.8%-17.4%) had sexually related personal distress, and 13.6% (95% CI, 11.9%-15.4%) had HSDD. The HSDD was more common among partnered than among unpartnered women (23.7% vs 5.9%; P < 0.001). Being partnered (adjusted odds ratio [AOR] = 4.21; 95% CI, 2.50-7.07), having vaginal dryness during intercourse (AOR = 2.37; 95% CI, 1.58-3.55), having symptomatic pelvic floor dysfunction (AOR = 1.92; 95% CI, 1.29-2.92), and having moderate-to-severe depressive symptoms (AOR = 4.15; 95% CI, 2.16-7.96) were independently associated with having HSDD. In a subanalysis, HSDD was more common among sexually active than sexually inactive women (31.5% vs 17.3%; P < 0.001). Furthermore, 32% (95% CI, 27.7%-38.3%) of partnered sexually active women had HSDD, as did 22% (95% CI, 11.5%-37.8%) of unpartnered sexually active women. CONCLUSIONS: HSDD is common and associated with potentially modifiable risk factors in older women. It should not be assumed that unpartnered older women are sexually inactive or are not distressed by low sexual desire.

Symptomatic pelvic floor disorders in community-dwelling older Australian women.

OBJECTIVES: To assess the prevalence, and factors associated with, pelvic floor disorders in a representative sample of community-dwelling older Australian women. METHODS: 1548 women, aged 65-79 years, were recruited to this cross-sectional study between April and August 2014. Pelvic floor disorders, including urinary incontinence (UI), fecal incontinence (FI), and pelvic organ prolapse (POP), were assessed using validated questionnaires. Multivariable logistic regression was used to assess factors associated with each, and having one or more pelvic floor disorders. RESULTS: Among 1517 women (mean age=71.5 ± 4.1 SD years), 47.2% (95% CI, 44.7-49.7%) of women had one or more pelvic floor disorders, with 36.2% (95% CI, 33.8-38.6%) having UI, 19.8% (95% CI, 17.8-21.9%) having FI, and 6.8% (95% CI, 5.6-8.2%) having POP. Of the women with POP, 53.4% had UI, 33% had FI and 26.2% had both. The proportion of women with one or more pelvic floor disorders increased with parity from 34.6% (95% CI, 7.8-11.7%) for nulliparous women, to 45.3% (95% CI, 40.3-59.1%) for 1-2 births, and 52.1% (95% CI, 48.3-55.8%) for ≥ 3 births. Obese women were more likely to have at least one pelvic floor disorder (OR=1.77; 95% CI, 1.36-2.31, p<0.01). CONCLUSION: Pelvic floor disorders are common in older women. Physicians caring for older women should be mindful that older women presenting with symptoms of one pelvic floor disorder are likely to have another concurrent pelvic floor problem.
