RESUMEN

Importance: Breast cancer is the most prevalent cancer globally with tremendous disparities both within specific regions and across different contexts. The survival pattern of patients with breast cancer remains poorly understood in sub-Saharan African (SSA) countries. Objective: To investigate the survival patterns of patients with breast cancer in SSA countries and compare the variation across countries and over time. Data Sources: Embase, PubMed, Web of Science, Scopus, and ProQuest were searched from inception to December 31, 2022, with a manual search of the references. Study Selection: Cohort studies of human participants that reported 1-, 2-, 3-, 4-, 5-, and 10-year survival from diagnosis among men, women, or both with breast cancer in SSA were included. Data Extraction and Synthesis: Independent extraction of study characteristics by multiple observers was performed using open-source software, then exported to a standard spreadsheet. A random-effects model using the generalized linear mixed-effects model was used to pool data. The Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) guideline for reporting was followed. Main Outcome and Measures: Survival time from diagnosis. Results: Forty-nine studies were included in the review with a sample size ranging from 21 to 2311 (total, 14 459; 196 [1.35%] men, 13 556 [93.75%] women, and 707 [4.90%] unspecified; mean age range, 38 to 71 years), of which 40 were summarized using meta-analysis. The pooled 1-year survival rate of patients with breast cancer in SSA was 0.79 (95% CI, 0.67-0.88); 2-year survival rate, 0.70 (95% CI, 0.57-0.80); 3-year survival rate, 0.56 (95% CI, 0.45-0.67); 4-year survival rate, 0.54 (95% CI, 0.43-0.65); and 5-year survival rate, 0.40 (95% CI, 0.32-0.49). The subgroup analysis showed that the 5-year survival rate ranged from 0.26 (95% CI, 0.06-0.65) for studies conducted earlier than 2010 to 0.47 (95% CI, 0.32-0.64) for studies conducted later than 2020. Additionally, the 5-year survival rate was lower in countries with a low human development index (HDI) (0.36 [95% CI, 0.25-0.49) compared with a middle HDI (0.46 [95% CI, 0.33-0.60]) and a high HDI (0.54 [95% CI, 0.04-0.97]). Conclusions and Relevance: In this systematic review and meta-analysis, the survival rates for patients with breast cancer in SSA were higher in countries with a high HDI compared with a low HDI. Enhancing patient survival necessitates a comprehensive approach that involves collaboration from all relevant stakeholders.

RESUMEN

BACKGROUND: Mid-upper arm circumference (MUAC) was recommended for screening of adolescents with obesity, although its diagnostic performance with respect to high-precision assessment of body composition remains unknown. OBJECTIVE: To evaluate the diagnostic performance of MUAC in identifying obesity and metabolic syndrome in U.S. adolescents. METHODS: A cross-sectional study was conducted using National Health and Nutrition Examination Survey (NHANES) data (2011-2018) of adolescents aged 12-19. We calculated the area under the receiver operating characteristic curve, sensitivity, specificity, positive and negative predictive values and likelihood ratios of MUAC in identifying obesity and metabolic syndrome. RESULTS: In our study, data of 5496 adolescents, including 2665 females, were analysed. The prevalence of obesity was higher in boys (14%) than girls (10%), whilst metabolic syndrome was more common in males (2.6%) than females (1.7%). The area under the curve (AUC) of MUAC in identifying obesity was 0.69 in boys and 0.86 in girls, whilst the AUC of MUAC in identifying metabolic syndrome was 0.91 in boys and 0.87 in girls. The optimal MUAC cut-off for identifying adolescents with obesity was 28.3 cm in boys (sensitivity: 64.8%, specificity: 85.5%) and 30.8 cm in girls (sensitivity: 67.9%, specificity: 90.1%). CONCLUSIONS: MUAC was a good indicator of both obesity and metabolic syndrome, with higher accuracy in girls.

RESUMEN

Preterm birth is one of the most common obstetric complications in low- and middle-income countries, where access to advanced diagnostic tests and imaging is limited. Therefore, we developed and validated a simplified risk prediction tool to predict preterm birth based on easily applicable and routinely collected characteristics of pregnant women in the primary care setting. We used a logistic regression model to develop a model based on the data collected from 481 pregnant women. Model accuracy was evaluated through discrimination (measured by the area under the Receiver Operating Characteristic curve; AUC) and calibration (via calibration graphs and the Hosmer-Lemeshow goodness of fit test). Internal validation was performed using a bootstrapping technique. A simplified risk score was developed, and the cut-off point was determined using the "Youden index" to classify pregnant women into high or low risk for preterm birth. The incidence of preterm birth was 19.5% (95% CI:16.2, 23.3) of pregnancies. The final prediction model incorporated mid-upper arm circumference, gravidity, history of abortion, antenatal care, comorbidity, intimate partner violence, and anemia as predictors of preeclampsia. The AUC of the model was 0.687 (95% CI: 0.62, 0.75). The calibration plot demonstrated a good calibration with a p-value of 0.713 for the Hosmer-Lemeshow goodness of fit test. The model can identify pregnant women at high risk of preterm birth. It is applicable in daily clinical practice and could contribute to the improvement of the health of women and newborns in primary care settings with limited resources. Healthcare providers in rural areas could use this prediction model to improve clinical decision-making and reduce obstetrics complications.

RESUMEN

BACKGROUND/OBJECTIVE: A successful Long-Term Weight Loss (LTWL) is associated with a more favorable metabolic disease risk profile. However, evidence is limited on the association of LTWL with obesity-related complications defined by Edmonton obesity staging system (EOSS). Hence, our study aims to assess the association between LTWL thresholds and obesity-related complications defined by EOSS among the adult US population. SUBJECTS/METHODS: We used data from the National Health and Nutrition Examination Survey (NHANES) from 2011 to 2018. Adults 18 years or older with overweight/obesity and long-term weight loss were included in the analysis. The association between long-term weight loss and obesity-related complications defined by EOSS was investigated. A multivariable logistic regression model was employed by adjusting for potential covariates. RESULTS: A total of 22,223 adults were included in the analysis. Overall, 61.8% of participants had long-term weight loss of <5%, and 4.8% of participants had successful long-term weight loss of 20% or greater. The highest long-term weight loss threshold ( ≥ 20%) had the lowest odds of EOSS stage ≥ 2 (odds ratio [OR] = 0.60; 95% CI:0.50, 0.72; p < 0.001). The lowest LTWL threshold (5-9.9%) was relatively associated with lower odds for EOSS stage ≥ 2 [OR = 0.69 95% CI: 0.61, 0.78, p < 0.001]. CONCLUSIONS: The LTWL categories were significantly associated with lower odds of EOSS stage ≥ 2 compared to EOSS 0 or 1. Future longitudinal research assessing the association between LTWL and EOSS components is recommended.

RESUMEN

OBJECTIVE: The aim of this study was to identify the best anthropometric indices for predicting metabolic syndrome in US adolescents. METHODS: A cross-sectional study analyzed data of adolescents ages 10 to 19 y using the National Health and Nutrition Examination Survey 2011 to 2018 data. The receiver operating characteristic areas under the curve (AUCs) of waist circumference z score, body roundness index, body mass index, and A Body Shape Index in identifying predicting metabolic syndrome were assessed. Furthermore, sensitivity, specificity, positive predictive value, negative predictive value, and positive and negative likelihood ratios of all anthropometric indices were calculated. RESULTS: A total of 5496 adolescents were included in the analysis. Waist circumference z score had an AUC of 0.90 (95% CI, 0.89-0.91), sensitivity of 95.0% (95% CI, 89.4-98.1), and specificity of 74.8% (95% CI, 73.6, 76.0). Body roundness index had an AUC of 0.88 (95% CI, 0.87-0.89), sensitivity of 96.7% (95% CI, 91.7-99.1), and specificity of 75.2% (95% CI, 74.1-76.4). Body mass index z score had an AUC of 0.83 (95% CI, 0.81-0.85), sensitivity of 97.5% (95% CI, 92.9-99.5), and specificity of 68.2% (95% CI, 66.9-69.4). A Body Shape Index had an AUC of 0.59 (95% CI, 0.56-0.61), sensitivity of 75.0% (95% CI, 66.3-82.5), and specificity of 50.9% (95% CI, 49.5-52.2). CONCLUSIONS: Our study found waist circumference z score and body roundness index were the best predictors of predicting metabolic syndrome compared with body mass index z score and A Body Shape Index in both boys and girls. We recommend that future studies develop global cutoff points for these anthropometric indices and examine their performance in a multi-country setting.

RESUMEN

OBJECTIVES: To provide evidence of validity, reliability and generalisability of results obtained using the Attitudes and Beliefs about Cardiovascular Disease (ABCD) Risk Questionnaire with a sample of the English population surveyed within the 'SPICES' Horizon 2020 Project (Nottingham study site), and to specifically evaluate the psychometric and factor properties of an as-yet untested five-item subscale relating to smoking behaviours. DESIGN AND SETTING: Community and workplace-based cross-sectional study in Nottingham, UK. PARTICIPANTS: 466 English adults fitting inclusion criteria (aged 18+ years, without known history of cardiovascular disease, not pregnant, able to provide informed consent) participated in the study. INTERVENTION: We revalidated the ABCD Questionnaire on a sample of the general population in Nottingham to confirm the psychometric properties. Furthermore, we introduced five items related to smoking, which were dropped in the original study due to inadequate valid samples. PRIMARY AND SECONDARY OUTCOME MEASURES: Psychometric and factor performance of untested five-item 'smoking behaviours' subscale.Psychometric and factorial properties in combination with the remaining 18 items across 3 subscales. RESULTS: Analyses of the data largely confirmed the validity, reliability and factor structure of the original ABCD Risk Questionnaire. Sufficient participants in our study provided data against additional five smoking-related items to confirm their validity as a subscale and to advocate for their inclusion in future applications of the scale. Exploratory factor analysis and confirmatory factor analysis calculations support some minor changes to the remaining subscales, which may further improve psychometric performance and therefore generalisability of the instrument. CONCLUSIONS: An amended version of the ABCD Risk Questionnaire would provide public health researchers and practitioners with a brief, easy-to-use, reliable and valid survey tool. The amended tool may assist public health practitioners and researchers to survey patient or public intentions and beliefs around three key areas of individually modifiable risk (physical activity, diet, smoking). TRIAL REGISTRATION NUMBER: ISRCTN Registry (ISRCTN68334579).

RESUMEN

Purpose: Poor sleep and cognitive deficits are often associated with increased drug use. However, no study has addressed the relationship between poor sleep, substance dependence, and metacognitive deficit in polysubstance users. Methods: This was a cross-sectional study with a simple random sampling involving community-dwelling polysubstance users (n = 326, age = 18-43 years) in Mizan, Ethiopia. Participants completed a brief sleep questionnaire, severity of dependence on khat (SDS-Khat), a brief meta-cognition questionnaire, and a socio-demographic survey. Results: Majority (56.4%) of the polysubstance users had sleep disturbance. Chronic health conditions [adjusted odds ratio (AOR) = 2.52, 95% confidence interval (CI) 1.31-4.85], chronic conditions in the family (AOR = 2.69, 95% CI 1.40-5.20), illiterate-primary level of educational status (AOR = 2.40, 95% CI 1.30-4.04), higher SDS-Khat score (AOR = 1.39, 95% CI 1.13-1.72), and lower meta-cognition score (AOR = 0.90, 95% CI 0.84-0.97) predicted poor sleep in the polysubstance users. Moreover, low metacognition score and high SDS score also predicted additional sleep disturbances like chronic sleep insufficiency, lethargy and restlessness after nighttime sleep, socio-occupational dysfunctions, and daytime disturbances in polysubstance users. Conclusion: Poor sleep, severe khat dependence, and metacognitive deficits are common in community polysubstance users. Moreover, poor sleep is associated with higher khat dependence, lower metacognitive ability, lower educational status, and the presence of chronic conditions in polysubstance users or their families.

RESUMEN

Purpose: Few studies have investigated the validity of the Athens insomnia scale (AIS) using a robust approach of both classical theory and the rating scale model. Therefore, in this study, we investigated psychometric validation of the AIS using both of these approaches in nurses. Methods: Nurses (n= 563, age= 33.2±7.1 years) working in health facilities in Saudi Arabia participated in a cross-sectional study. Participants completed the AIS, socio-demographics tool, and sleep health-related questions. Results: Confirmatory factor analysis (CFA) favored a 2-factor structure with both comparative fit index (CFI), and incremental fit index (IFI) having values above 0.95. The 2-factor model had the lowest values of Akaike information criterion (AIC), root mean square error of approximation (RMSEA), χ 2, and χ 2/df. This 2-factor structure showed configural invariance (CFI more than 0.95, RMSEA less than 0.08, and Χ2/df less than 3), and metric, scalar, and strict invariance (based on Δ CFI ≤-0.01, and Δ RMSEA ≥ 0.015 criteria). No ceiling/floor effects were seen for the AIS total scores. Infit and outfit mean square values for all the items were within the acceptable range (<1.4, >0.6). The threshold estimates for each item were ordered as expected. Cronbach's α for the AIS tool, factor-1 score, factor-2 score was 0.86, 0.82, and 0.72, respectively. AIS factor scores-1/2 were significantly associated with a habitual feeling of tiredness after usual night sleep (p<0.001), Impairment of daytime socio-occupational functioning (p<0.05), and with a feeling of daytime fatigue, irritability, and restlessness (p<0.05). Conclusion: The findings favor the validity of a 2-factor structure of the AIS with adequate item properties, convergent validity, and reliability in nurses.

RESUMEN

BACKGROUND: Despite an improvement in the healthcare system, cardiovascular diseases (CVDs) remain the leading cause of morbidity and mortality worldwide. Improving knowledge is a key for behavioral change towards prevention of CVDs. However, up-to-date evidence is limited on the effect of interventions on CVD knowledge. Thus this study aimed to synthesize comprehensive evidence on the type and effectiveness of community-based interventions (CBIs) to improve knowledge related to CVDs. METHODS: We performed a systematic review of studies that tested the effectiveness of CBIs in improving CVD knowledge. International databases including MEDLINE, EMBASE, CINAHL, PSYCINFO and Cochrane register of controlled studies were searched for studies published between January 2000 and December 2019. The Cochrane risk of bias tools were used to assess the methodological quality of included studies. Since CVD knowledge was measured using various tools, results were synthesized narratively and reported in line with the reporting guideline for Synthesis Without Meta-analysis (SWiM). The review protocol is registered in the PROSPERO database (CRD42019119885). RESULTS: 7 randomized and 9 non-randomized controlled trials involving 34,845 participants were included. Most of the interventions targeted the general population and majorities delivered the intervention to groups of individuals. Likewise, most of the interventions employed various intervention components including health education using different strategies. Overall, most studies showed that CBIs significantly improved knowledge related to CVDs. CONCLUSION: Community-based CVD preventive interventions are effective in improving knowledge related to CVD and risk factors. Measures to scale up CBIs are recommended to improve an individual's level of CVD knowledge, which potentially helps to counter the growing burden of CVDs.

RESUMEN

In recent years, morbidity and mortality due to cancer has been increasing in Ethiopia, putting it among the most important public health issues. Cancer and associated complications can be prevented provided that effective interventions are put in place to control risk factors. Therefore, this study aimed to assess the level of knowledge and practice of preventable behavioural risk factors of cancer. We conducted a cross-sectional study among 200 college students in Northeast Ethiopia utilising quantitative methods of data collection. Data on socioeconomic characteristics, health belief variables, knowledge and behavioural risk factors (alcohol consumption, tobacco smoking, physical activity and dietary practice) were collected. The level of knowledge and practice was summarised using descriptive statistics. To investigate the variation in knowledge and practice across sociodemographic characteristics, we performed Pearson Chi-square test or Fisher's exact test. The majority (81.0%) of participants was male and 82.0% were in the age group of 18-24 years. More than half (61.0%) of them had poor knowledge about the behavioural risk factors of cancer. Nearly one-third (30.5%) consume alcohol, whereas 16.0%, 18.0% and 20.0%, respectively, smoke tobacco, consume street food and packed-fried snacks daily. Alcohol consumption (p = 0.02) and level of vigorous physical activity (p = 0.001) were significantly higher among males than females. Alcohol consumption, tobacco smoking and unhealthy dietary practice were remarkably high, whereas knowledge towards the behavioural risk factors was low. Therefore, health education and collaborative action between different sectors are needed to counter the emerging problem. The trial is registered in ClinicalTrials.gov (https://register.clinicaltrials.gov) NCT04269018.

RESUMEN

BACKGROUND: The burden of cardiovascular diseases (CVDs) greatly varies between and within countries. Low- and middle-income countries (LMICs) and vulnerable communities of high-income countries (HIC) share disproportionately higher burden. Evidence is limited on the level of CVD knowledge and risk perception in vulnerable communities. Hence, in this study, we assessed the level of CVD knowledge, risk perception and change intention towards physical activity and healthy diet among vulnerable communities in Antwerp, Belgium and Nottingham, England. Furthermore, we investigated the socioeconomic disparities particularly in the Antwerp setting. METHOD: A cross-sectional study was performed among 1,424 adults (958 in Antwerp and 466 in Nottingham) aged 18 or older among selected vulnerable communities. Districts or counties were selected based on socioeconomic and multiple deprivation index. A stratified random sampling was used in Antwerp, and purposive sampling in Nottingham. We determined the level of CVD knowledge, risk perception and intention towards a healthy lifestyle in Antwerp and Nottingham using a percentage score out of 100. To identify independent socioeconomic determinants in CVD knowledge, risk perception, intention to PA and healthy diet, we performed multilevel multivariable modeling using the Antwerp dataset. RESULTS: The mean knowledge percent score was 75.4 in Antwerp and 69.4 in Nottingham, and only 36.5% and 21.1% of participants respectively, had good CVD knowledge (scored 80% or above). In the multivariable analysis using the Antwerp dataset, level of education was significantly associated with (1) CVD knowledge score (Adjusted ß = 0.11, 95%CI: 0.03, 0.18), (2) risk perception (0.23, 95%CI: 0.04, 0.41), (3) intention to physical activity (PA) (0.51, 95%CI: 0.35, 0.66), and (4) healthy diet intention (0.54, 95%CI: 0.32, 0.75). Furthermore, those individuals with a higher household income had a better healthy diet intention (0.44, 95%CI: 0.23, 0.65). In contrast, those who were of non-European origin scored lower on intention to have a healthy diet (-1.34, 95%CI:-2.07, -0.62) as compared to their European counterparts. On average, intention to PA was significantly higher among males (-0.43, 95%CI:-0.82, -0.03), whereas females scored better on healthy diet intention (2.02, 95%CI: 1.46, 2.57). CONCLUSIONS: Knowledge towards CVD risks and prevention is low in vulnerable communities. Males have a higher intention towards PA while females towards a healthy diet and it also greatly varies across level of education. Moreover, those born outside Europe and with low household income have lower healthy diet intention than their respective counterparts. Hence, CVD preventive interventions should be participatory and based on a better understanding of the individuals' socioeconomic status and cultural beliefs through active individual and community engagement.

RESUMEN

OBJECTIVE: This study aimed to synthesise the existing evidence on the performance of mid-upper arm circumference (MUAC) to identify children and adolescents with overweight and obesity. DESIGN: Systematic review and meta-analysis. SETTING: We searched PubMed, EMBASE, SCOPUS, Cochrane Library, Web of Science, CINAHL and Google scholar databases from their inception to December 10, 2021, for relevant studies. There were no restrictions regarding the language of publication. Studies reporting measures for the diagnostic performance of MUAC compared with a reference standard for diagnosing overweight and obesity in children and adolescents aged 2-19 years were included. PARTICIPANTS: A total of 54 381 children and adolescents from twenty-one studies were reviewed; ten studies contributed to meta-analyses. RESULTS: In boys, MUAC showed a pooled AUC of 0·92 (95 % CI 0·89, 0·94), sensitivity of 84·4 (95 % CI 84·6, 90·8) and a specificity of 86·0 (95 % CI 79·2, 90·8), when compared against BMI z-score, defined overweight and obesity. As for girls, MUAC showed a pooled AUC of 0·93 (95 % CI 0·90, 0·95), sensitivity of 86·4 (95 % CI 79·8, 91·0), specificity of 86·6 (95 % CI 82·2, 90·1) when compared against overweight and obesity defined using BMI z-scores. CONCLUSION: In comparison with BMI, MUAC has an excellent performance to identify overweight and obesity in children and adolescents. However, no sufficient evidence on the performance of MUAC compared with gold standard measures of adiposity. Future research should compare performance of MUAC to the 'golden standard' measure of excess adiposity.

RESUMEN

Objectives: To synthesize evidence on the effectiveness of community-based interventions for cardiovascular disease (CVD) prevention in low- and middle-income countries (LMICs) to inform design of effective strategies for CVD prevention. Methods: We searched MEDLINE, EMBASE, CINAHL, Cochrane register of controlled studies and PSYCINFO databases for studies published between January 2000 and June 2019. Other studies were identified from gray literature sources and review of reference lists of included studies. The primary outcomes for the review were those aimed at primary prevention of CVD targeting physical activity, diet, smoking and alcohol consumption. Results: Database searches yielded 15,885 articles and 94 articles were identified through snowball searching. After screening, the articles from LMICs were 32 emanating from 27 studies: 9 cluster randomized trials, eight randomized controlled trials and 10 controlled before and after studies. Community-based interventions successfully improved population knowledge on CVD and risk factors and influenced physical activity and dietary practices. Evidence of interventions on smoking cessation and reduced alcohol consumption was inconsistent. Conclusion: This evidence should inform policy makers in decision-making and prioritizing evidence-based interventions.

RESUMEN

There is a lack of uniformity in developing and validating indicators of nutritional status among People Living with Human Immunodeficiency Virus (PLHIV). Experiences from low and middle-income countries are scant, and differences in methodological and analytical approaches affect the comparability and generalizability of findings. Therefore, this study investigated the performance of individual diversity score (IDDS) as a proxy indicator of nutritional status among PLHIV. We conducted a facility-based cross-sectional study among 423 PLHIV who were under Antiretroviral Treatment (ART) at clinics in Bahir-Dar, Ethiopia. We collected data on sociodemographic, dietary, clinical, and anthropometric measures. Dietary intake was assessed using 24-Hour dietary recall. Body Mass Index (BMI) was calculated to assess the nutritional status of study subjects. The receiver operating characteristic (ROC) curve analysis was used to assess the ability of the IDDS and Minimum Dietary Diversity for Women (MDD-W) to detect poor nutritional status. Furthermore, sensitivity, specificity, Predictive Values (PPs), and Likelihood Ratios (LRs) were calculated at different cut-off points. IDDS showed good reliability with Cronbach's Alpha of 0.76. The Area Under the Curve (AUC) of IDDS was 78.5 (95%CI 73.9-83.4). At the IDDS cut-off of 4, the sensitivity and specificity of IDDS to indicate nutritional status were 88.0% (95%CI 81.0-93.0) and 71.0% (95%CI 66.0-76.0), respectively. The AUC of MDD-W was 74.1%, and at the cut-off of 4 the sensitivity and specificity of MDD-W to indicate undernutrition were 73.0% and 72.0%, respectively. Both IDDS and MDD-W have good accuracy as a proxy indicator for measuring the nutritional status of PLHIV. In the prevention of undernutrition among PLHIV especially in a resource-limited setting, IDDS and MDD-W can be used to assess nutritional status.

RESUMEN

Cardiovascular diseases (CVDs) remain a leading cause of morbidity and mortality globally. Despite preventive community-based interventions (CBIs) seem efficacious in reducing CVD risks, a comprehensive up-to-date synthesis on the effectiveness of such interventions in improving physical activity (PA) is lacking. We performed a systematic review and meta-analysis of community-based CVD preventive interventions aimed at improving PA level. MEDLINE, EMBASE, CINAHL, Cochrane register and PSYCINFO databases were searched in October 2019 for studies reported between January 2000 and June 2019. We assessed the methodological quality of included studies using the Cochrane risk of bias tools. We performed a random-effects meta-analysis and meta-regression to pool estimates of various effect measures. Results are reported in line with the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) guideline. Our study protocol was registered in the PROSPERO database (CRD42019119885). A total of 44 randomized and 20 non-randomized controlled studies involving 98,919 participants were included. Meta-analyses found that CBIs improved the odds of attaining the recommended PA level (at least 150 min of moderate and vigorous PA (MVPA)/week) at 12 month (OR: 1.62; 95%CI: 1.25-2.11) and 18 to 24 months of follow-up (OR: 1.46; 95%CI: 1.12-1.91). Furthermore, interventions were effective in improving metabolic equivalents of task at 12 month (standardized mean difference (SMD): 0.28; 95% CI: 0.03-0.53), MVPA time at 12 to 18 months (SMD: 0.34; 95%CI: 0.05-0.64), steps per day (SMD: 0.32; 95%CI: 0.08-0.55), and sitting time (SMD: -0.25; 95%CI: -0.34 to -0.17). Subgroup analyses found that interventions in low- and middle-income countries showed a greater positive effect on attainment of recommended PA level (OR: 1.40; 95%CI: 1.02-1.92) than those in high-income countries (OR: 1.31; 95%CI: 0.96-1.78). Moreover, interventions targeting high-risk groups showed greater effectiveness than those targeting the general population (OR: 1.76; 95%CI: 1.30-2.39 vs. 1.17; 95%CI: 0.89-1.55). In conclusion, community-based CVD preventive interventions have a positive impact on improving the PA level, albeit that relevant studies in lower-middle and low-income countries are limited. With the rising burden of CVDs, rolling out CBIs targeting the general population and high-risk groups are needed to control the growing CVD-burden.

RESUMEN

Eating behaviours have been associated both with being underweight or overweight and poor growth. The Children's Eating Behaviour Questionnaire (CEBQ) is a widely used measure of child eating behaviours. The instrument is, however, mostly validated in high-income countries, with a scarcity of evidence among developing countries such as Ethiopia. The present study aims to assess the cultural adaptability and validity of the CEBQ to be used in Ethiopia. We conducted a school-based cross-sectional study among 542 caregivers of children aged 3-6 years in selected preschools. Tests of factorial validity, convergent validity and reliability were performed. The Confirmatory Factor Analysis model indicated that eight subscales provided the best fit (root-mean-square error of approximation = 0⋅05 (90 % CI 0⋅045, 0⋅055); Comparative Fit Index = 0⋅92 and Tucker-Lewis Index = 0⋅90) after seven items from the original CEBQ were removed. Convergent validity with child's weight status was found for emotional overeating, food fussiness, satiety responsiveness and slowness in eating subscales. Reliability, measured using Cronbach's α, provided values between 0⋅50 and 0⋅79. The eight-factor structure of the CEBQ showed adequate content validity and provided factorial, discriminant and convergent validity among preschool children. Further replication of the study among low-income countries is essential to improve the literature on children's eating behaviours.

RESUMEN

This article describes data collected retrospectively on a cohort of esophageal, colorectal and prostate cancer patients registered in the patient log book of Tikur Anbessa Specialized Hospital, Ethiopia, from January 1, 2012 to December 31, 2017. The key variables studied include histological characteristics of each type of cancer, clinical and TNM stages, baseline laboratory results (Carcinoembryonic antigen (CEA) for colorectal cancer, Prostate-Specific Antigen (PSA) for prostate cancer, hemoglobin level, etc.), clinical characteristics including sign and symptoms, family history of cancer, diagnostic and treatment modalities a patient received for each type of cancer. The event status (death) was also collected using death certificates (whenever available) and supplemented by telephone interviews with the patient or attendant. Furthermore, lifestyle characteristics of patients including tobacco use, alcohol consumption, khat ('Catha edulis') chewing, etc. and socioeconomic characteristics including age, sex, region of residence, marital status, and educational level were also collected. The aim that led to conduct the study that generated these data was to describe clinical presentation, histological characteristics, survival pattern, and to identify determinants of mortality among cancer patients in Ethiopia. Thus, independent survival analyzes were performed using Kaplan-Meier estimates and life table analysis. Furthermore, Cox's proportional hazards regression was developed to investigate the survival pattern and determinants of cancer specific mortality among colorectal, esophageal and prostate cancer patients.

RESUMEN

BACKGROUND: Cancer is an emerging public health problem in Ethiopia. A significant proportion of premature cancer deaths are preventable. The socioeconomic impact of cancer can be considerably reduced provided that effective interventions are put in place to control risk factors. Text-messaging has been currently targeted as a simple and efficient tool for providing people with health information. OBJECTIVE: To evaluate the effectiveness of mobile text messages in improving knowledge and perception on cancer and behavioral risks among college students. METHODS: Design: a single-blind, 2-arm randomized controlled trial will be used. Setting: the study will be conducted among public colleges in Dessie town, Northeast Ethiopia. Study population: students who are studying in all public colleges. Intervention: a text message related to cancer risk factors once a day for two months. Control groups will receive general health messages daily for two months. Data: Socioeconomic characteristics, health belief variables, and behavioral risk factors of cancer will be collected before and after the intervention. Text messages will be provided based on the health belief model (HBM). Primary outcomes: cancer risk knowledge score and risk perception will be measured at baseline and 6 months post-randomization. Secondary outcomes: a change in mean healthy diet score, physical activity level, alcohol intake, and tobacco use will be measured at baseline-, 3, and 6 months post-randomization. Analysis: We will compute descriptive statistics for each outcome pre and post-intervention. To test the change in knowledge and perception, paired t-test will be used. Analysis of Covariance will be used to test over group comparison. TRIAL REGISTRATION: ClinicalTrials.gov (https://register.clinicaltrials.gov) NCT04269018.

RESUMEN

Khat (Catha edulis) chewing is linked to several social, psychological, and health-related problems. Studies show that khat is associated with gastrointestinal and nervous system diseases. However, little is known about khat's effect on the cardiovascular system. This case report describes acute myocardial infarction (AMI) among two young adults who chew khat frequently, but who do not have underlying cardiovascular disease (CVD) risk factors. Case 1 is a 29-year-old apparently healthy man who presented with severe, squeezing, left-side chest pain after consumption of khat. Most of the laboratory results were within the normal range except for his serum troponin level, which was 400 times more than the normal limit. The patient was diagnosed with Killip class IV, ST-segment elevation, anteroseptal AMI. Case 2 is a 25-year-old man who is a frequent khat chewer. He presented with sudden-onset, severe, squeezing, retrosternal chest pain after khat chewing and vigorous activity. The patient was diagnosed with (Killip class III) acute ST-elevation myocardial infarction with cardiogenic pulmonary edema. These case reports describe two young adult male patients who were confirmed of having AMI with no known risk factors. Both cases had a similar history of frequent khat chewing and the onset of AMI after it, implying that khat could be an important CVD risk factor among young adults. Hence, it is essential to explore further the epidemiology and association between khat use and AMI. Both molecular and population-level studies could help to establish the causal relationship of khat and CVD.

RESUMEN

Unintended pregnancy is among the major challenges of public health and a major reproductive health issue, due to its implications on the health, economic and social life of a woman and her family mainly in low and middle-income countries, particularly sub-Saharan Africa. The study aimed to assess unintended pregnancy and associated factors among pregnant women in Ethiopia using multilevel analysis from the EDHS 2016. We used the data from the 2016 Ethiopian Demographic and Health Survey, comprised of 1122 pregnant women. The prevalence of unintended pregnancy was determined through descriptive statistics and multilevel logistic regression was performed to identify factors associated with unintended pregnancy. Variables with a p-value < 0.05 in the selected model were considered as significantly associated and an adjusted odds ratio was used to determine the strength and direction of the association. The prevalence of unintended pregnancy was 29.7% (CI 27.0%, 32.4%), of which 20.4% were mistimed and 9.3% unwanted. Being multi-para and fertility preference to have no more child were associated with a higher risk of unintended pregnancy whereas husbands' polygamy relation, having no women autonomy, and living in Afar and Somali regions showed a less likely risk of experiencing an unintended pregnancy. This study showed that the proportion of women who experienced unintended pregnancy is considerably high. Parity, fertility preference, polygamy relation, women autonomy, and region were identified factors associated with unintended pregnancy. Therefore, policymakers at all levels, reproductive health experts, and concerned organizations should emphasize minimizing unintended pregnancy targeting the regional variation at large. Researchers have to explore the regional variations through a qualitative study.
