Abstract
What is already known about this topic? Anemia is a significant public health issue affecting women globally. Prior studies in China predominantly concentrated on anemia in pregnant or reproductive-age women, leaving a gap in available data concerning anemia in non-pregnant women of all age groups in China. What is added by this report? In 2021, the prevalence of anemia and moderate to severe anemia among women aged 18 years and older in urban China was 14.8% and 5.7%, respectively. Anemia prevalence exhibited significant variations based on factors such as age, body mass index (BMI), geographic location, and socioeconomic status. What are the implications for public health practice? The strategy for addressing anemia should account for non-pregnant women aged 30-49 years and those aged 70 years and older, taking into consideration differences related to socioeconomic development and geography.

Abstract
BACKGROUND Anaemia disproportionately affects women of reproductive age in sub-Saharan Africa including Nigeria. Yet, community-based studies on the prevalence and determinants of anaemia among women of reproductive age are scarce in Nigeria. DESIGN A cross-sectional community-based survey using a nationally representative sample. OBJECTIVES This study described anaemia prevalence and its associated factors among women of reproductive age, pregnant women, and non-pregnant women in Nigeria. METHODS We analysed data from the 2018 Nigeria Demographic and Health Survey. Pregnant women with a haemoglobin level less than 11 g/dL and non-pregnant women with a haemoglobin level less than 12 g/dL were considered anaemic. Anaemia was also categorized as mild, moderate, and severe. Pearson's chi-square test was used to evaluate the association between anaemia status and independent variables. All variables with ρ ⩽ 0.25 in bivariate analyses were further analysed using complex sample logistic regression. RESULTS Anaemia prevalence was 57.8%, 57.4%, and 61.1% for women of reproductive age, non-pregnant women, and pregnant women, respectively. The prevalence of severe anaemia was 1.6%, 1.5%, and 2.3% for overall women of reproductive age, non-pregnant women, and pregnant women, correspondingly. The southern regions, rural residence, low education, unemployment, low wealth index, and non-use of modern contraceptives significantly increased the likelihood of anaemia and severe anaemia among women of reproductive age and non-pregnant women. The likelihood of being anaemic was significantly increased by large family size among women of reproductive age and by being underweight among non-pregnant women. The South-East region, rural residence, low education, and unemployment were significantly associated with anaemia among pregnant women. The South-South region and unemployment increased the likelihood of severe anaemia among pregnant women. Short stature significantly reduced the odds of being anaemic and severely anaemic among pregnant women. CONCLUSIONS Anaemia prevalence among all categories of women of reproductive age is high in Nigeria. Predictors of anaemia prevalence and severity should be considered in policies intended to reduce anaemia among women of reproductive age in Nigeria.

Abstract
Objective: The effect of indoor air pollution from different fuel types on the anemia
status among non-pregnant women is rarely studied. This study aimed to
assess the link between indoor air pollution from different fuel types and
anemia among non-pregnant women of reproductive ages in Ethiopia. Method: The secondary data from the 2016 Ethiopian Demographic and Health Survey data
have been employed for this study. The anemia status of women in
reproductive age was the outcome variable with multiple outcomes as
(moderate to severe, mild, and no anemia) and households using biomass fuel
and clean fuel were selected for this study. Multinomial logistic regression
was employed to estimate the association of biomass fuel use with the anemia
status controlling for the predictor variables. Relative risk ratio was
calculated at 95% confidence interval. An independent-sample t-test was used
to assess the mean difference in blood hemoglobin level (g/dL) between the
two fuel users. A p value < 0.05 was considered significant. Result: From the total of 10,961 participants included in this study, the proportion
of anemia in women of non-reproductive age was 41.8% and 19.4% among biomass
fuel and clean fuel users, respectively, with a mean blood hemoglobin level
of 12.71 (±1.81) g/dL. In the final model, women using biomass fuel for
cooking were 47% more likely to have mild anemia than households who use
cleaner fuels, whereas the association was insignificant for moderate to
severe anemia. Biomass fuel users were also found to have 5.8 g/dL lower
blood hemoglobin level than the clean fuel user (p < 0.001). Conclusion: The use of biomass fuel was associated with reduced blood hemoglobin levels
and significantly associated with mild anemia levels in women of
reproductive age in Ethiopia. National efforts should be in place to reduce
indoor air pollution from biomass fuels.

Abstract
BACKGROUND Respiratory syncytial virus (RSV) causes respiratory tract infections, which may require hospitalization especially in early infancy. Transplacental transfer of RSV antibodies could confer protection to infants in their first months of life. METHODS In this first-in-human, placebo-controlled study, 502 healthy non-pregnant women were randomized 1:1:1:1 to receive a single dose of unadjuvanted vaccine containing 30/60/120 µg of RSV fusion (F) protein stabilized in the prefusion conformation (RSVPreF3), or placebo. RESULTS Solicited local adverse events (AEs) were more frequently reported in the RSVPreF3 groups (4-53.2%) vs placebo (0-15.9%); most were mild/moderate. Unsolicited AEs were comparably reported among groups. Three serious AEs were reported; none was vaccination-related. Compared with pre-vaccination values, anti-RSV A neutralizing antibody geometric mean titers and anti-RSVPreF3 immunoglobulin G geometric mean concentrations increased 8-14-fold and 12-21-fold at day (D)8 and persisted 5-6-fold and 6-8-fold higher until D91 in the RSVPreF3 groups vs 1-fold in placebo. Comparisons at D8 and D31 showed that the higher dose levels were significantly more immunogenic than the lowest one. CONCLUSIONS The RSVPreF3 vaccine was well tolerated and immunogenic. The 60 and 120 µg dose levels were selected for further investigation in pregnant women.

Abstract
BACKGROUND There is limited evidence supporting an association between Mycoplasma hominis, Ureaplasma urealyticum and Ureaplasma parvum and symptoms or disease in non-pregnant women. However, testing and reporting of these organisms frequently occurs, in-part due to their inclusion in multiplex-PCR assays for sexually transmitted infection (STI) detection. We investigated if M. hominis, U. urealyticum and U. parvum were associated with symptoms and/or signs in non-pregnant women attending a sexual health service. METHODS Eligible women attending Melbourne Sexual Health Centre completed a questionnaire regarding sexual practices and symptoms. Symptomatic women underwent examination. Women were assessed for bacterial vaginosis (BV) and vulvovaginal candidiasis (VVC), and tested for M. hominis, U. urealyticum and U. parvum, and four non-viral STIs using a commercial multiplex-PCR. RESULTS 1,272 women were analysed. After adjusting for STIs and VVC, M. hominis was associated with abnormal vaginal discharge (aOR=2.70, 95%CI:1.92-3.79), vaginal malodour (aOR=4.27, 95%CI:3.08-5.91), vaginal pH>4.5 (aOR=4.27, 95%CI:3.22-5.66) and presence of clue cells (aOR=8.08, 95%CI:5.68-11.48). Ureaplasma spp. were not associated with symptoms/signs. BV was strongly associated with M. hominis (aOR=8.01, 95%CI:5.99-10.71), but was not associated with either Ureaplasma spp. In stratified analyses, M. hominis was associated with self-reported vaginal malodour and clinician-recorded vaginal discharge in women with BV, but not with symptoms/signs in women without BV. CONCLUSION Only M. hominis was associated with symptoms/signs, and these were manifestations of BV. Importantly, M. hominis was not associated with symptoms/signs in women without BV. These findings do not support routine testing for M. hominis, U. urealyticum and U. parvum in non-pregnant women.

Abstract
Objectives. Restless Legs Syndrome is a movement disorder characterized by unpleasant sensations in the legs described as a burning, tingling, etc. Symptoms become worse in the evening and are relieved by moving the limbs. The idiopathic form of the disease is associated with a lack of dopamine, and the secondary form is associated with iron deficiency anemia, pregnancy, and kidney disease. The aim of this study was to investigate the incidence of iron deficiency anemia in pregnant women and non-pregnant women suffering from RLS.Methods. The study was conducted on a sample of 231 pregnant women aged 18-50. The pregnant women were interviewed at the outpatient clinic of the Department of Gynaecology and Obstetrics. This study also included a control group of 231 age-compatible non-pregnant women. Women who met the international criteria for diagnosing the syndrome filled in a sociodemographic questionnaire.Results. A statistically significant association between the existence of iron deficiency anemia and RLS in the sample of the examined women was proven (p < 0.001). It was also shown that RLS is more frequent in a sample of anemic pregnant women than non-anemic pregnant women (p = 0.008).Conclusion. Iron deficiency anemia is related with RLS. Pregnant women with RLS are more likely to be anemic than pregnant women without RLS.

Abstract
Introduction: Fear of childbirth (FOC) has been mostly studied in peripartum women; however, it can be present in non-pregnant young women, and the question is whether it occurs even before pregnancy planning. Objective: (1) to determine the prevalence of clinically significant FOC in non-pregnant female students, and (2) to investigate the role of anxiety sensitivity (AS), trait anxiety, childbirth pain expectancy, and sources of birth knowledge for FOC. Methods: Non-pregnant female students (N = 374) from different study programmes (health studies, social sciences and humanities, and biotechnical studies) participated in the study. They completed Wijma Delivery Expectancy/Experience Questionnaire (W-DEQ, version A), The State-Trait Anxiety Inventory (STAI-T), Anxiety Sensitivity Index (ASI), the average expected labor pain, and sources of information about childbirth. Results: The results showed that 25.9% of students reported clinically significant FOC. FOC could be predicted by postponing pregnancy planning, the high expectancy of labor pain, high trait anxiety, and high physical dimension of AS. Students from health sciences reported a lower level of FOC, as opposed to social science and humanities' students. Students reported receiving the most information about childbirth from family and the least from the professional books. Conclusions: Fear of childbirth is highly prevalent in the sample of young nulliparous women with one in four women reporting clinically significant fear. The higher levels of the FOC could be predicted, by AS, trait anxiety, expected labor pain, and sources of knowledge about the childbirth. Implications of the findings are discussed.

Abstract
Introduction Iron deficiency anemia (IDA) is a highly afflicting condition which affects young children of growing age and reproductive age women in countries of lower economies. Conventional oral iron salts have poor absorption and gastrointestinal side effects. Microencapsulated liposomal iron pyrophosphate is a novel compound with enhanced palatability, higher bioavailability, and consequently increased adherence among people with IDA. This study aims to assess the efficacy of microencapsulated iron pyrophosphate sachets in non-pregnant women with IDA. Methods It was a 12-week long, open label clinical trial conducted with 558 IDA women. Participants were advised one sachet of microencapsulated liposomal iron pyrophosphate (Ferfer®) twice daily. At baseline, and every four-week interval, serum hemoglobin levels and taste tolerability were assessed. Data was entered and analyzed using SPSS v. 24 (IBM Corp, Armonk, NY, USA). Results Four hundred and thirty-seven women completed the trial. The mean serum Hb level at baseline was 8.71 ± 2.24 which increased to 10.47 ± 1.69 by the end of 12 weeks (p < 0.001). Conclusion Treatment of IDA with microencapsulated liposomal iron pyrophosphate sachets significantly increases serum hemoglobin levels in non-pregnant women of reproductive age.

Abstract
Globally, severe anemia impacts millions of non-pregnant women. However, studies on the prevalence of severe anemia through large epidemiologic surveys among non-pregnant women have been scarce in China. In this study, we aimed to study the prevalence of severe anemia and its determinants among non-pregnant women living in rural areas of China. Data were gathered for 712,101 non-pregnant women aged between 21 and 49 years who attended the 2012 National Free Preconception Health Examination Project. Severe anemia in non-pregnant women was defined as a hemoglobin (Hb) concentration lower than 80 g/L. Associated factors were analyzed using univariate and multivariate logistic regression methods. Out of the 712,101 non-pregnant women living in the rural areas of China, 1728 suffered from severe anemia, with a prevalence of 0.24% (95% confidence interval (CI): 0.23–0.25%). Results from the multivariable logistic regression showed that elderly (adjusted odds ratio (aOR) = 3.08), living in the northwest region (aOR = 2.88), having a history of anemia (aOR = 5.76), with heavy menstrual blood loss (aOR = 1.84), and with a history of using an intra-uterine device (aOR = 1.47) etc., were independent determinants for women with severe anemia in rural China. The prevalence of severe anemia among Chinese non-pregnant women living in the rural areas was lower than the reported global prevalence. Prevention and intervention programs for severe anemia are required among non-pregnant women of reproductive age in the rural areas of China.

Abstract
OBJECTIVE To compare the appearance and measurement of Cesarean hysterotomy scar before pregnancy and at 11-14 weeks in a subsequent pregnancy. METHODS This was a prospective cohort study of women aged 18-35 years who had one previous Cesarean delivery (CD) at ≥ 37 weeks. Women were examined with saline contrast sonohysterography 6-9 months after CD. A scar defect was defined as large if scar thickness was ≤ 2.5 mm. Women were followed up and those who became pregnant were examined by transvaginal ultrasound at 11-14 weeks. Scar thickness was measured and scars were classified subjectively as a scar with or without a large defect. A receiver-operating characteristics curve was constructed to determine the best cut-off value for scar thickness to define a large scar defect at the 11-14-week scan. RESULTS A total of 111 women with a previous CD were scanned in the non-pregnant state and at 11-14 weeks in a subsequent pregnancy. The best cut-off value for scar thickness to define a large scar defect at 11-14 weeks was 2.85 mm, which had 90% sensitivity (18/20), 97% specificity (88/91) and 95% accuracy (106/111). In the non-pregnant state, large scar defects were found in 18 (16%) women and all were confirmed at the 11-14-week scan. In addition, a large defect was found in three women at 11-14 weeks that was not identified in the non-pregnant state. CONCLUSION The appearance of the Cesarean hysterotomy scar was similar in the non-pregnant state and at 11-14 weeks in a subsequent pregnancy. Copyright © 2016 ISUOG.

Abstract
Cobalamin and folate are especially important for women of childbearing age due to their ubiquitous role in fetal growth and development. Population-based data on cobalamin and folate status are lacking from Nepal, where diets are mostly vegetarian. The objectives of the study were to investigate cobalamin and folate intake and status, and to explore associations with socio-demographics, anthropometrics, anemia, and dietary habits. Following a random selection of geographical clusters, we collected blood samples from 500 non-pregnant women and 24-h dietary recalls and food frequency questionnaires from a subsample of 379 women. Twenty percent of the women did not consume any food containing cobalamin during the days recalled, and in 72% nutritional cobalamin intake was <1 μg/day. Eighty-four percent of the women had cobalamin intake lower than the estimated average requirement (EAR) (<2 μg/day). In contrast, only 12% of the women had a folate intake less than 100 μg per day, whereas 62% had intake between 100 and 320 μg. Low plasma cobalamin (<150 pmol/L) was found in 42% of the women, most of whom (88%) also had elevated levels of methylmalonic acid. Our results indicated a high prevalence of nutritional cobalamin deficiency, while folate deficiency was uncommon.

Abstract
BACKGROUND Representative national data of prevalence of anemia and casual factors are missing for population group of reproductive aged non-pregnant females in Serbia. The purpose of the current study was to assess the prevalence and grades of anemia and its association with risk factors among non-pregnant women of childbearing age in Serbia. METHODS Data were collected as part of the first "National Health Survey", a cross-sectional, multistage cluster survey, conducted on 677 households in Serbia. A total of 708 females 20-49-year-old were recruited. Socioeconomic, anthropometric, dietary and reproductive data have been collected and hemoglobin levels were determined. RESULTS The overall prevalence of anemia was 27.7% (196/708) [95% Confidence Interval (CI), 24.5-31.1%], and more precisely mild (21.9%), moderate (5.1%) and severe (0.7%) anemia. Belgrade residential area [odds ratio 2.11 (95% CI 1.27-3.50), p=0.004], shortage of living space per person (<16m(2)) [2.18 (1.17-4.03), p=0.014], body mass index (<25) [1.55 (1.04-2.29), p=0.029], alcohol intake [0.52 (0.33-0.81), p=0.004], lack [2.48 (1.31-4.70), p=0.005] or fruit juice consumption 1-2 [2.76 (1.46-5.23), p=0.002] times a week and previously diagnosed, but treated [2.62 (1.29-5.35), p=0.008] or not treated [3.57 (1.71-7.45), p<0.001] anemia were independent predictors of low hemoglobin levels. Deficit of electricity supply and insufficient living space in households, increased risk of moderate anemia, while likelihood of being mild and moderately anemic, augmented with previously diagnosed but, treated or not treated anemia and lack or juice consumption 1-2 times a week. CONCLUSIONS High prevalence of anemia among non-pregnant women and its association to casual factors needs continuous monitoring and control efforts for anemia in Serbia.

Abstract
BACKGROUND/OBJECTIVES The use of multimicronutrient (MMN) supplementation to reduce the burden of anaemia in non-pregnant women of reproductive age has been little studied, particularly in Africa. The objective of the study was to evaluate haematological outcomes in non-pregnant, rural Gambian women of reproductive age, receiving daily MMN supplements for 1 year. SUBJECTS/METHODS The study in 293 women aged from 17 to 45 years old was nested within a double-blind, randomized placebo-controlled trial of periconceptional MMN supplementation [ISRCTN 13687662], using the United Nations International Multiple Micronutrient Preparation (UNIMMAP), received daily for 1 year or until conception. Red cell parameters and free erythrocyte protoporphyrin concentration were measured at baseline and after 12 months in those women who did not conceive. RESULTS Anaemic women (haemoglobin concentration <12 g per 100 ml) were more likely to be older and in economic deficit at baseline. Mean change in haemoglobin concentration was +0.6+/-1.4 g per 100 ml in the intervention arm and -0.2+/-1.2 g per 100 ml in the placebo arm (P<0.001). After supplementation with MMN, the relative risk of anaemia (<12 g per 100 ml) was 0.59 (0.46, 0.76) compared with placebo. Anaemic subjects at baseline showed an increase in mean haemoglobin from 10.6 g per 100 ml to 11.8 g/l (P<0.001) after MMN supplementation. CONCLUSIONS MMN supplementation should be considered as a strategy for improving the micronutrient and haematological status of non-pregnant women of reproductive age.
