Associations of early marriage and early childbearing with anemia among adolescent girls in Ethiopia: a multilevel analysis of nationwide survey

Abstract Background Early marriage and early childbearing are common practices in Ethiopia. Girls who get married and give birth at a very young age are more likely to experience several health problems including anemia among others. However, the effects of early marriage and early childbearing on anemia status of adolescent girls have not been quantified in previous studies. In this study, we assessed whether early marriage and early childbearing measured at both individual and community levels are associated with adolescent anemia. Methods We analyzed data from the 2016 demographic and health survey of Ethiopia. Our study focused on 3172 late female adolescents (15–19 years). We used the chi-squared test and spearman correlation coefficients for bivariate analysis. The relationship between early marriage and childbearing with anemia was evaluated using multilevel binary logistic regression models while controlling other determinants. Results Overall prevalence of anemia among female adolescents was 23.8% (95% CI; 22.3–25.2). Our multivariable multilevel analysis showed that individual-level marital status (AOR = 1.53, 95% CI = 1.06–2.02) and community-level childbearing status (AOR = 2.80, 95% CI 1.25–6.29) were positively associated with anemia among female adolescents. Conclusion Our findings show the presence of significant association between early marriage & early childbearing with adolescent anemia. Therefore, there is a need for effective policies and programs to end the practice of early child marriage and the consequent adolescent pregnancy in Ethiopia. This will help to improve nutritional status of adolescent girls as well as nutritional outcomes of their children.

Abstract Background: The diagnosis of keratoconus in the early stages of the disease is necessary to initiate an early treatment of keratoconus. Furthermore to avoid possible refractive surgery that could produce ectasias. This study aims to describe the topographic, pachymetric and aberrometry characteristics in patients with keratoconus, subclinical keratoconus and normal corneas. Additionally to propose a diagnostic model of subclinical keratoconus based in binary logistic regression models Methods: The design was a cross-sectional study. It included 205 eyes from 205 patients distributed in 82 normal corneas, 40 subclinical keratoconus and 83 established keratoconus The rotary Scheimpflug camera (Pentacam® type) analyzed the topographic, pachymetric and aberrometry variables. It performed a descriptive and bivariate analysis of the recorded data. A diagnostic and predictive model of subclinical keratoconus was calculated with the statistically significant variables Results: Statistically significant differences were observed when comparing normal corneas with subclinical keratoconus/ in variables of the vertical asymmetry to 90º and the central corneal thickness. The binary logistic regression model included the minimal corneal thickness, the anterior coma to 90º and posterior coma to 90º. The model properly diagnosed 92% of cases Conclusions: The differential diagnosis between normal cases and subclinical keratoconus depends on the mínimum corneal thickness, the anterior coma to 90º and the posterior coma to 90º.

Assessment Approach

There are longstanding disagreements between the rodeo industry stakeholders and animal welfare advocates about the wellbeing of the animals used in events. The current study aims to determine whether qualitative behavioural assessment (QBA) is effective in identifying the emotional state of calves in so-called calf-roping events. Still images of calves captured from videos of calf-roping were shown to two groups: practitioners (n = 7) and students (n = 16). For each image, they scored (on a scale of 1–10) 12 descriptive terms—e.g., stressed, energetic, confused, frightened—based on how strongly they thought the animal was experiencing that emotion. Scores were analysed using Factor Analysis and Ordinal Logistic Regression models, while inter-rater reliability was assessed using Intra-Class Correlation Coefficients. The same imagery (video and images) were analysed for behaviours associated with the calves’ ears, neck, legs and tail to develop a behavioural ethogram, which was analysed with Binary Logistic Regression and Anova wrapping. The students were also surveyed to assess their empathy towards animals. The chase phase attracted significantly higher scores for stressed (µ = 5.0, p < 0.001), agitated (µ = 5.1, p < 0.001), anxious (µ = 5.0, p < 0.001) and frightened (µ = 5.0, p < 0.001), and the behavioural ethogram revealed that calves commonly galloped (p < 0.001) and held their tails rigidly during this phase (p = 0.010). In contrast, the recovery phase was characterised by significantly higher scores for calm (µ = 3.0, p < 0.001), contented (µ = 2.7, p < 0.001) and relieved (µ = 1.6, p < 0.001), and calves moved slower (p < 0.001) with more neutral ear positions (ears axial p = 0.008, ears forward p = 0.010). A clear pre- and post-rope effect was evident, showing that QBA indicated that calves were anxious while being chased and were relieved when they had been released. The survey data revealed that students who had more empathy for animals in pain and for those used in experiments were more empathetic towards calves during the chase phase. They felt that calves being chased were agitated, anxious, stressed, frightened and confused. These results confirm that QBA has the potential as a tool for assessing the welfare of animals used in rodeos.

Abstract Background: Early marriage and early pregnancy is a social as well as medical problem in developing countries, which may have an impact on health and nutritional status of teenage mothers. Therefore, the objective of this study was to determine the influencing factors of early childbearing (ECB) and its consequences on nutritional status of Bangladeshi mothers. Methods: Data was extracted from the last survey of Bangladesh Demographic and Health Survey (BDHS-2014). Women who delivered their first baby before their age 20 years are considered as ECB mothers. Nutritional status was measured by body mass index (BMI) which was categorized as (i) under nutrition (BMI<18.5 kg/m2), (ii) normal (18.5≤BMI<25 kg/m2) and (iii) over nutrition BMI≥25 kg/m2). Chi-square test and both univariable and multivariable logistic regressions, and z-proportional test were used in this study. Results: This study revealed that the prevalence of ECB among currently non-pregnant mothers in Bangladesh was 83% (urban: 77% and rural: 85.8%). A multivariable binary logistic regression model provided the following six risk factors of ECB: (i) living location (division), (ii) respondents’ education, (iii) husbands’ education, (iv) household wealth quintiles, (v) respondents’ age at first marriage, and (vi) number of family members. Still 17.6% mothers were undernourished in Bangladesh; among them 18.5% and 13.4% were ECB and non- ECB mothers respectively, while 25.5% mothers were over nourished. Univariable model demonstrated that ECB mothers had a greater risk to be undernourished than non-ECB mothers [COR=1.26, 95% CI: 1.11-1.43; p<0.01]. Conclusions: In this study, some modifiable factors were found as predictors of ECB in Bangladesh. ECB mothers were more prone to become under-nourished. These findings can be considered to reduce the number of ECB mothers in Bangladesh consequently to improve their nutritional status.

Hospital Cardiac Arrest

Background: Substantial facility-level variation in survival exists following in-hospital cardiac arrest. Yet, specific resuscitation practices that distinguish hospitals with higher cardiac arrest survival remain unknown. Methods: We surveyed hospitals that submitted >20 adult in-hospital cardiac arrest cases to Get With The Guidelines (GWTG)-Resuscitation between 2012 and 2013 about resuscitation practices at their facility. We then used data from GWTG-Resuscitation to calculate risk-standardized rates for survival to discharge for each hospital, and categorized facilities into the top quintile, middle 2 to 4 quintiles, and bottom quintile based on their performance. The association between resuscitation practices and quintiles of survival was evaluated using hierarchical proportional odds logistic regression models. Results: Overall, 150 of 192 active adult hospitals (78.1%) facilities completed the study survey and 131 facilities with >20 cases comprised the final study cohort. Risk-standardized survival rates after in-hospital cardiac arrest varied substantially (median: 23.7%; range: 9.2%-37.5%). Several resuscitation practices were associated with survival on bivariate analysis, although only three were significant after multivariable adjustment: tracking interruptions in chest compressions (adjusted OR for being in a higher survival quintile category, 2.7 [95% CI: 1.2-5.9]; P=0.01); reviewing cardiac arrest cases monthly or quarterly (adjusted OR for being in a higher survival quintile category, 8.6 [1.8-40.0] for monthly and 6.9 [1.5-31.3] for quarterly; P=0.03); and inadequate resuscitation training (adjusted OR for at least a moderate barrier, 0.31 [0.12, 0.83]; P=0.02). Conclusion: Tracking interruptions in chest compressions, frequent review of cardiac arrest cases, and adequate resuscitation training are potentially key resuscitation practices associated with higher in-hospital cardiac arrest survival.

When studying sexual desire during pregnancy, most research focuses on the pregnant woman’s sexual desire and almost never takes into account her sexual partner. The novelty of this study is that sexual desire during pregnancy is studied from the point of view of the pregnant woman and from that of her male partner. The goal of this study is to see how sexual desire behaves during pregnancy in both partners. For this, a descriptive, longitudinal, and multistage study was designed. Methodologically, in the first stage, the different study variables were described through a single-variate analysis. In the second stage, one variable was related to others by means of a bivariate analysis. Finally, in the third stage, a multivariate analysis was done, composed of binary logistic regression models and latent growth curves. The results confirm that pregnancy influences the sexual desire of both partners, and that sexual desire behaves differently in women than in men during pregnancy. Men have higher levels of sexual desire throughout pregnancy as compared to women. The first trimester of pregnancy is the period when women have less sexual desire.

Infeksi HPV dan pre kanker serviks (sel-sel abnormal pada leher rahim yang dapat menyebabkan kanker) telah menurun secara signifikan sejak vaksin HPV digunakan.Cakupan vaksinasi HPV masih rendah di Indonesia.Orang tua adalah pemegang tanggung jawab dan kewajiban utama di dalam penjaminan pemenuhan hak dasar anak untuk mendapatkan vaksinasi. Tujuan penelitian adalah untuk mengetahui faktor yang berhubungan (sikap, kepercayaan, dukungan orang tua) dengan kesediaan vaksinasi pada remaja putri. Jenis penelitian adalah survey analitik dengan pendekatan cross sectional. Penelitian dilaksanakan di SD Muhammadiyah Macanan, Ngemplak dan SMPN 1 Berbah, Sleman pada Mei-Juli 2019. Jumlah sampel 127 remaja putri beserta orang tuanya dipilih dengan accidental sampling. Instrumen kuesioner dan telah dilakukan uji validitas. Analisis bivariat dengan uji chi square (dukungan instrumen, emosional, kepercayaan orang tua) dan uji fisher exact (dukungan informasi dan sikap). Hasil penelitian menunjukkan 92,9% orang tua tidak memberikan dukungan informasi, 85% tidak memberikan dukungan instrumen, 75,6% memberikan dukungan emosional kepada putrinya terkait vaksinasi. Faktor yang berhubungan dengan kesediaan vaksinasi adalah dukungan instrumen (p-value = 0,048). Faktor yang menjadi pertimbangan terbanyak orang tua untuk mengijinkan anaknya di vaksinasi adalah keamanan vaksin (81,1%). Kesimpulan: Ada hubungan dukungan instrumen orang tua dengan kesediaan vaksinasi HPV pada remaja putri. HPV infections and cervical precancers (abnormal cells on the cervix that can lead to cancer) have dropped significantly since HPV vaccine has been in use. HPV vaccination coverage is still low in Indonesia. Parents are the main responsibility and obligation in guaranteeing the fulfillment of the child's basic rights to get a vaccination. The purpose of this study was to determine the related factors (attitudes, beliefs, parental support) with the willingness to participate in HPV vaccination among adolescent girls. This type of the study was analytic survey with cross sectional approach. The study was conducted at SD Muhammadiyah Macanan, Ngemplak and SMPN 1 Berbah, Sleman in May-July 2019. The sample was 127 adolescent girl and their parents selected by accidental sampling. The instrument used questionnaire and already undergone validity test. The bivariate analysis used chi square test (instrument and emotional support, parental trust) and fisher exact test (information support and attitude). The results showed 92.9% of parents did not provide information support, 85% did not provide instrument support, 75.6% provided emotional support to their daughters related to vaccination. Factors related to the willingness of vaccinations were instrument support (p-value = 0.048). The factor that was considered by most parents to allow their children to be vaccinated was vaccine safety (81.1%). Conclusion: There was a correlation between parental instrument support and HPV vaccination willingness of adolescent girls.

Abstract Background Functional disability and multimorbidity are common among older people. However, little is known about the relationship between functional disability and different multimorbidity combinations. We aimed to identify multimorbidity patterns and explore the associations between these patterns and functional disability. Methods We investigated a multi-stage random sample of 1871 participants aged ≥60 years and covered by long-term care insurance in Shanghai, China. Multimorbidity was defined as the simultaneous presence of two or more chronic diseases in an individual. Participants completed scales to assess basic and instrumental activities of daily living (BADL and IADL, respectively). Multimorbidity patterns were identified via exploratory factor analysis. Binary logistic regression models were used to determine adjusted associations between functional disability and number and patterns of multimorbidity. Results Multimorbidity was present in 74.3% of participants. The prevalence of BADL disability was 50.7% and that of IADL disability was 90.7%. There was a strong association between multimorbidity and disability. We identified three multimorbidity patterns: musculoskeletal, cardio-metabolic, and mental-degenerative diseases. The cardio-metabolic disease pattern was associated with both BADL (OR 1.28, 95%CI 1.16–1.41) and IADL (OR 1.41, 95%CI 1.19–1.68) disability. The mental-degenerative disease pattern was associated with BADL disability (OR 1.55, 95%CI 1.40–1.72). Conclusions Multimorbidity and functional disability are highly prevalent among older people covered by long-term care insurance in Shanghai, and distinct multimorbidity patterns are differentially associated with functional disability. Appropriate long-term healthcare and prevention strategies for older people may help reduce multimorbidity, maintain functional ability, and improve health-related quality of life.

AbstractPeptic ulcer disease (PUD) is caused by many sociodemographic and economic risk factors other than H. pylori infection. However, no studies reported an association between PUD and the number of household members. We showed the number of family members affected by PUD based on sex in a Korean population. This cross-sectional study used 1998–2009 data from the Korea National Health and Nutrition Examination Survey of the Korea Centers for Disease Control and Prevention. Multiple binary logistic regression models adjusted for confounders were constructed to analyze the association of PUD with the number of household members. The number of household members was associated with PUD, age, body mass index (BMI), waist circumference, systolic blood pressure, hemoglobin, glucose, location (urban/rural), income, education level, stress, current drinking, and smoking in both sexes. Men with other household members had a higher PUD risk compared to men or women living alone (reference), and the opposite was observed for women. Men with 4 household members had a higher PUD risk than men living alone in the model adjusted for age, BMI, income, location, education, and stress (OR = 2.04 [95% CI 1.28–3.27], p value = .003). Women with more than 6 household members had a lower PUD risk than women living alone in the adjusted model (OR = 0.50 [0.33–0.75], p value = .001). Women with more household members had a lower PUD risk. However, more men had PUD than women regardless of the number of household members.

Abstract Background Odour-based tools targeting gravid malaria vectors may complement existing intervention strategies. Anopheles arabiensis are attracted to, and stimulated to oviposit by, natural and synthetic odours of wild and domesticated grasses associated with mosquito breeding sites. While such synthetic odour lures may be used for vector control, these may have limited efficacy when placed in direct competition with the natural source. In this study, workflows developed for plant-feeding pests was used to design and evaluate a chimeric odour blend based on shared attractive compounds found in domesticated grass odours. Methods Variants of a synthetic odour blend, composed of shared bioactive compounds previously identified in domesticated grasses, was evaluated sequentially in a two-choice olfactometer to identify a ratio-optimized attractive blend for malaria vectors. During this process, blends with ratios that were significantly more attractive than the previously identified synthetic rice blend were compared to determine which was most attractive in the two-choice olfactometer. To determine whether all volatile components of the most attractive blend were necessary for maximal attraction, subtractive assays were then conducted, in which individual components were removed for the most attractive blend, to define the final composition of the chimeric blend. Binary logistic regression models were used to determine significance in all two-choice assays. The chimeric blend was then assessed under field conditions in malaria endemic villages in Ethiopia, to assess the effect of dose, trap type, and placement relative to ground level. Field data were analyzed both descriptively and using a Welch-corrected t-test. Results A ratio-optimized chimeric blend was identified that significantly attracted gravid An. arabiensis under laboratory conditions. In the field, trap captures of An. arabiensis and Anopheles pharoensis were dependent on the presence of the lure, trap type (CDC, BG Sentinel and Suna traps), placement relevant to ground level, with low release rates generally luring more mosquitoes. Conclusions The workflow designed for the development of chimeric lures provides an innovative strategy to target odour-mediated behaviours. The chimeric lure identified here can be used in existing trapping systems, and be customized to increase sustainability, in line with goals of the Global Vector Control Response Group.
