Prevalence and Biopsychosocial Factors Associated With a Current Episode of Low Back Pain Among Adults With a Previous History of Low Back Pain: A Cross-sectional Study of Market Traders in an African Population.

Low back pain (LBP) is the leading cause of years lived with disability globally, with Nigeria having one of the greatest burdens. A current episode of LBP is important in Nigeria, but the associated factors are unknown. This cross-sectional study investigated the prevalence, biomechanical, and psychosocial factors associated with a current episode of LBP among 700 adult market traders with previous LBP in an urban Nigerian population. Descriptive, bivariate, and multivariate analyses were conducted. The prevalence of a current episode of LBP was 76.4%. Factors associated with an increased risk of a current episode of LBP in a decreasing order of importance were exposure to biomechanical factors (aggregate [total] score) (odds ratio [OR] = 1.535; 95% confidence interval [CI] = 1.398-1.685); anxiety (OR = 1.182; 95% CI = 1.089-1.282); fear-avoidance beliefs (physical activity) (OR = 1.139; 95% CI = 1.029-1.261); fear-avoidance beliefs (work) (OR = 1.105; 95% CI = 1.047-1.165); while factors associated with a reduced risk of a current episode of LBP were ability to take breaks in the job in addition to scheduled breaks (OR = .430; 95% CI = .240-.773) and ability to control the order and pace of tasks (OR = .477; 95% CI = .236-.965). Occupational biomechanical and psychosocial factors were associated with a current episode of LBP in logistic regression models explaining 52.7% and 73.1% of the variation in a current episode of LBP. Occupational biomechanical factors, particularly handling large and bulky objects at arm's length and kneeling and squatting, produced the greatest risk of a current episode of LBP. PERSPECTIVE: Occupational biomechanical factors, occupational psychosocial factors, and personal psychosocial factors such as anxiety and fear-avoidance beliefs are associated with a current episode of LBP in Nigeria. Pragmatic public health and occupational health initiatives that modify exposure to these factors may be required in Nigeria.

Occupational biopsychosocial factors associated with neck pain intensity, neck-disability, and sick leave: A cross-sectional study of construction labourers in an African population.

INTRODUCTION: The burden and impact of neck pain is high in African countries including Nigeria. This study investigated the occupational biomechanical and occupational psychosocial factors associated with neck pain intensity, neck disability and sick leave amongst construction labourers in an urban Nigerian population. METHODS: This cross-sectional study measured clinical neck pain outcomes, occupational biomechanical factors, and occupational psychosocial factors. Descriptive, and univariate/multivariate inferential statistical analyses were conducted. RESULTS: Significant independent factors associated with neck pain intensity were order and pace of tasks being dependent on others (ß = 0.35; p<0.0001); inability to take breaks in addition to scheduled breaks (ß = 0.25; p<0.0001); inability to work because of unexpected events (ß = 0.21; p<0.0001); inability to control the order and pace of tasks (ß = 0.20; p<0.0001); and weight of load (ß = 0.17; p<0.0001); accounting for 53% of the variance in neck pain intensity. Significant independent factors associated with neck disability were weight of load (ß = 0.30; p<0.0001); duration of load carriage (ß = 0.16; p = 0.01); working under time pressure/deadlines (ß = 0.16; p = 0.02); and accounting for 20% of the variance in neck disability. Significant independent factor associated with sick leave was duration of load carriage (ß = 0.15; p = 0.04), in a non-significant regression model explaining -4% of the variance in sick leave. Addition of pain intensity significantly explained more variance in neck disability (31.0%) but less variance in sick leave (-5%), which was not statistically significant (F (10, 190) = 0.902, p = 0.533). CONCLUSIONS: Occupational biomechanical factors may be more important than occupational psychosocial factors in explaining neck disability and sick leave. In contrast, occupational psychosocial factors may be more important than occupational biomechanical factors in explaining neck pain intensity in this population in Nigeria.

Community-based non-pharmacological interventions for pregnant women with gestational diabetes mellitus: a systematic review.

BACKGROUND: Non-pharmacological interventions are the first line of Gestational diabetes mellitus (GDM) management. Community-based interventions are cheaper, more accessible, with higher patient satisfaction. OBJECTIVES: To systematically review community-based non-pharmacological interventions and evaluate their effectiveness for GDM. SEARCH STRATEGY: Twelve bibliographic databases and reference list of related studies from inception until January 2022. SELECTION CRITERIA: All primary studies of community-based non-pharmacological interventions for GDM reported in English which investigated any behavioural or clinical outcome(s). DATA COLLECTION AND ANALYSIS: Data were extracted using modified Cochrane's data extraction template. Studies were evaluated using Cochrane Collaboration's risk of bias tool. Narrative synthesis was used to summarise findings. This study is registered with PROSPERO (CRD42021257634). MAIN RESULTS: Twenty-seven studies involving 6,242 pregnant women with GDM investigated self-management programmes, medical nutrition/diet therapy, exercise/physical activity, combined diet and exercise, calcium plus vitamin D supplementation, and continuous glucose monitoring. Self-management programmes were more effective than routine care in improving self-efficacy, two-hour postprandial blood glucose, and lifestyle behaviours but were as effective as routine care in improving infant birth weight. Self-management programmes were superior to or as effective as usual care in improving fasting blood glucose, blood glucose control, glycated haemoglobin, macrosomia, and preterm delivery. Medical nutrition/diet therapy was more effective than usual care in improving postprandial blood glucose levels. Postprandial blood glucose levels were better improved by regular supervised exercise plus daily brisk walks or a daily walking intervention than routine obstetric care or no treatment. The effects of exercise/physical activity programmes were mostly inconsistent for other outcomes. Diet and exercise were superior to diet alone in reducing maternal weight gain although there were similar outcomes for other pregnancy and foetal outcomes. Limited or conflicting evidence was found for other outcomes and interventions including calcium and vitamin D supplementation and continuous glucose monitoring intervention. CONCLUSIONS: Community-based non-pharmacological interventions are more effective than placebo; and are more or as effective as usual care. Self-management programmes and medical nutrition/diet therapy had the most promising GDM outcomes. FUNDING: There was no funding for this study. The study design, data collection, data analysis and interpretation, and writing of this manuscript were not influenced externally by any funder.

Minimal-contact physical interventions for pregnant women with musculoskeletal disorders: a systematic review of randomised and non-randomised clinical trials.

This review summarised minimal-contact physical interventions and their effects on pain, disability and quality of life in pregnant women with musculoskeletal disorders. Twelve bibliographic databases were systematically searched until December 31 2020. PEDro Scale was used for quality assessments. Narrative synthesis of 10 eligible studies was conducted. Education and multimodal home exercises plus handbooks/multimodal individual/group exercises; and self-management programmes improved pain intensity, sick leave and disability in pregnant women with lumbopelvic pain. Individual home-based progressive muscle relaxation exercises; unsupervised water exercises plus information using handbooks/videos/music; group multimodal exercises plus home exercises and information/education; and partner massage plus information using booklets/photographs reduced pain intensity in pregnant women with low back pain. Non-rigid/customised lumbopelvic belts plus information reduced pain intensity more significantly than rigid belts or stabilisation exercises plus information among pregnant women with pelvic girdle pain. Minimal contact interventions are effective and may be utilised during infectious disease pandemics.

Patterns of Anemia in Married Women and Their Children in Cambodia: A Synthetic Cohort Analysis.

AIM: To explore the prevalence of anemia in three cohorts of women, namely, married yet to be mothers, married and are mothers, and currently pregnant, to ascertain the patterns in anemia in women. METHODS: We analyzed a sample of 130,965 married women from four Demographic Health Surveys: 2000, 2005, 2009 and 2015. The primary focus for the analysis was married women aged 15 to 49 years. In the absence of a longitudinal data that followed the same women over the periods, a synthetic cohort of the women of that age-group was constructed to get women aged 15 to 64 years over the four surveys. Women who were aged 15 to 19 years in 2000 were the same as those 30 to 34 years in 2015, while those aged 45 to 49 years in 2000 were the same as 60 to 64 years in 2015. RESULTS: Logistic regression revealed that young mothers were significantly more infected (p < .001). Pregnancy affected anemia in the women (p < .001). Being younger and richer were associated with odds ratios of 0.599 (95% confidence interval, CI: [0.560, 0.640]) and 0.765 (95% CI: [0.726, 0.807]) for anemia, respectively. Being pregnant had odds ratio of 1.642 (95% CI: [1.439, 1.872]) for anemia. CONCLUSION: Public health strategies should target social deprivation at the household level while addressing maternal health issues. An analysis of data on unmarried women and their children is recommended.

A Comparison of the Characteristics of Maternal Near-Misses and Maternal Deaths in Enugu, Southeast Nigeria: A 3-Year Prospective Study.

BACKGROUND: Maternal near-misses, also known as severe acute maternal morbidity, have become globally recognized as an appropriate indicator of obstetric care. Women experiencing maternal near-misses are more in number than maternal deaths, and can provide more specific and detailed evidence, as the patient herself can be a leading source of useful information. OBJECTIVE: To determine the frequency of maternal near-misses and maternal deaths in the University of Nigeria Teaching Hospital in Ituku-Ozalla, Enugu, document the primary determinant factor that caused these, and compare cases of maternal near-miss and maternal deaths. METHODS: This was a 3-year prospective study of all women admitted for delivery or within 42 days of delivery or termination of pregnancy at the hospital. Data were collected prospectively in consecutive patients in a pro forma manner and entered into SPSS version 17 for Windows. RESULTS: There was a total of 2,236 deliveries, of which 88 had severe maternal outcomes. Of the latter, 60 were maternal near-misses, while 28 suffered maternal death. The maternal near-miss:mortality ratio was found to be 2.14. The maternal mortality ratio here was 1,252 per 100,000. All the 88 women that had severe maternal outcomes lived at least 5 km from the hospital. The leading organ-system dysfunction in this study was cardiovascular, manifesting as shock and cardiac arrest, and respiratory, manifesting as gasping and cyanosis. Leading complications were severe hemorrhage, anemia, and hypertensive disorders. The pattern of complications was similar in both near-misses and maternal deaths, but cases of hypertensive disorders and exploratory laparotomy as an intervention for those with organ dysfunction were noted to be higher in near-miss cases, and differences were statistically significant. CONCLUSION: It was concluded that despite numerous similarities in the characteristics of patients who had had maternal near-misses or died, our study points out that those who succumb to death are often <40 years of age, poorly educated, unemployed, usually present as unbooked emergencies from a distance >5 km and suffer maternal death within 24 hours of presentation.

Determinants of Childhood Anemia in India.

We analyzed a sample of 112714 children from the 2015-2016 Indian National Fertility and Health Survey with available data on hemoglobin. Multinomial logistic regression models were used to establish associations between parent anemia, household characteristics and nutritional intake of children. Linear regression analysis was also conducted to see the link between the household characteristic and childhood nutritional intake on one hand and hemoglobin levels on the other hand. A number of socio-demographic factors, namely maternal age, type of residence and maternal education, as well as wealth index, among others correlate with incidence of childhood anemia. For instance, whereas 52.9% of children in the richest households were anemic, 63.2% of children in the poorest household were anemic (p < 0.001). Mean Vitamin A intake in the last six months was 0.63 (0.626-0.634) which was 0.18% of the recommended intake. Mean iron intake, from sources other than breast milk, in the last 24 hours was 0.29 (0.286-0.294) and 2.42% of the recommended daily intake. Fifty-nine percent (58.5%) of the children surveyed were anemic (Hb level: 9.75 g/dL [9.59-9.91]). Children with anemia were more prone to being iron deficient (odds ratio [OR]: 0.981 (0.961-1.001), Vitamin A deficient (OR: 0.813 (0.794-0.833)), and have lower maternal hemoglobin level (OR: 1.992 (1.957-2.027)). Combining nutritional supplementation and food-fortification programmes with reduction in maternal anemia and family poverty may yield optimal improvement of childhood anemia in India.

Choice of birth place among antenatal clinic attendees in rural mission hospitals in Ebonyi State, South-East Nigeria.

BACKGROUND: Low utilization of health facilities for delivery by pregnant women poses a public health challenge in Nigeria. AIM: To determine the factors that influence the choice of birth place among antenatal clinic attendees. METHODOLOGY: This was a cross-sectional study of the eligible antenatal clinic attendees recruited at Mater Misericordiae Hospital, Afikpo and Saint Vincent Hospital, Ndubia in Ebonyi State from February 1, 2016 to June 30, 2016. Analysis was done using EPI Info 7.21 software (CDC Atlanta Georgia). RESULTS: A total of 397(99.3%) completely filled questionnaires were collated and analysed. Approximately 71% of the health facilities closest to the respondents had maternity services. It took at least 1 hour for 80.9% of the respondents to access health facilities with maternity services. Most (60.2%) of the respondents had at least one antenatal clinic attendance and majority of them did so at public hospitals. Approximately 43.8% of the respondents were delivered by the skilled birth attendants. The respondents' age and the couple's educational level, history of antenatal clinic attendance, distance of the health facility and availability of transport fare had a significant effect on delivery by skilled birth attendants. The common determinants of birth place were nearness of the health facilities, familiarity of healthcare providers, improved services, sudden labour onset and cost. Also 61.7% of the respondents chose to deliver in public health facilities due to favourable reasons but this could be hampered by the rudeness of some healthcare providers at such facilities. A significant proportion of private health facilities had unskilled manpower and shortage of drugs. CONCLUSION: A greater proportion of women will prefer to deliver in health facilities. However there are barriers to utilization of these facilities hence the need to address such barriers.

Inequities in Access to Maternal Health Care in Enugu State: Implications for Universal Health Coverage to Meet Vision 2030 in Nigeria.

We explored the equity issues in access to maternal health services in Enugu State, Nigeria. We conducted a cross-sectional survey of 1,600 women who had babies within 6 months prior to the survey, drawn from four urban and rural local government areas in Enugu State of Nigeria, using structured questionnaire. Focus group discussions were held with grandmothers and fathers of the new babies. In-depth interviews were held with health workers. Results showed that inequities exist in access to quality health service when the mothers needed health care. The inequities in access to quality antenatal care (ANC) services were driven mainly by the type of localities of the mothers. Mothers who lived in the urban areas had better access ( p = .013). Other factors that facilitated access to better ANC services included being educated ( p = .049), being older ( p = .009), and belonging to the richer wealth quintile ( p < .001). With respect to access to health service when in need of health, differentials were seen with respect to living in urban residence ( p < .001), distance to the health facilities ( p < .001), and being rich ( p < .001). Access to health services was associated with odds ratio of 3.6 (95% CI [2.9, 4.4]) and 1.54 (95% CI [1.3, 2.0]) for living in urban residence and existence of good ANC service points, respectively. Similarly, living in urban areas was associated with an odds ratio of 1.3 (95% CI [1.1, 1.6]) of having access to good ANC services. These inequities in access to health service were also captured in the qualitative data. Suboptimal access to quality health care by segments of the populations poses challenge to universal health coverage in Enugu State. Action is needed to promote coordinated delivery of health services to ensure no one is left behind, irrespective of where they live or the socioeconomic strata they are born into.

Effect of early amniotomy on the outcome of spontaneous labour: a randomized controlled trial of pregnant women in Enugu, South-east Nigeria.

BACKGROUND: Early amniotomy is common in obstetric practice but, its effectiveness has not been proven. OBJECTIVES: To determine the effects of early amniotomy on the duration of labour, and other maternal / neonatal outcomes of uncomplicated pregnancies in Enugu, South-east Nigeria. METHODS: A randomized controlled study of 214 consenting term pregnant women at the University of Nigeria Teaching Hospital Enugu, Nigeria. Intervention group received amniotomy early in active labour while the control group had their membranes conserved. RESULTS: Mean duration of labour for the amniotomy group (279.4 ± 53.7 minutes) was significantly lower than that of control group (354.4 ± 67.5 minutes), (t = -8.988, p <0.001). Three (3.8%) women in amniotomy group needed oxytocin augmentation as against 21 (19.6%) women in the control group RR = 0.14, (CI 95%: 0.04 - 0.46), NNT = 16. The two groups did not vary with respect to cesarean section rate, newborn Apgar scores, and need for new born special care unit admission. CONCLUSION: Early amniotomy when compared to fetal membrane conservation reduced the duration of labour and need for oxytocin augmentation among term singleton pregnant women in Enugu, Nigeria. Its routine use in well selected cases may reduce prolonged labour and its complications.
