Prevalence and factors associated with low bone mineral density in Saudi women: a community based survey

Increasing Burden of Lower-Extremity Fractures in the Middle East and North Africa (MENA): A 30-Year Epidemiological Analysis

BACKGROUND

Lower-extremity fractures (LEFs) account for >30% of all skeletal injuries, contributing to the global health and economic burden. Fracture epidemiology in the Middle East and North Africa (MENA) region has been studied little. Health factors and disease epidemiology differ greatly among populations in MENA despite cultural, political, and economic similarities among the region's countries. This study examined the epidemiology of LEFs and the need for rehabilitation in MENA from 1990 to 2019.

METHODS

We examined the epidemiology of fractures of the pelvis, hip, femur, patella, tibia, fibula, ankle, and foot bones using Global Burden of Disease (GBD) data. Fracture incidence, counts, and rates were measured for males and females across age groups in the 21 MENA countries as identified by the GBD data set. Associations between years of healthy life lost due to disability (YLD) resulting from fracture and the Socio-demographic Index (SDI) were analyzed.

RESULTS

In contrast to the global trend, the age-standardized incidence rate (ASIR) of LEFs in the MENA region increased by 4.57% from 1990 to 2019. In 2019, the highest ASIR among fractures was attributed to fractures of the patella, fibula, tibia, or ankle (434.36 per 100,000), most frequently occurring among those 20 to 24 years of age. In 2019, the highest ASIR of all fractures was noted in Saudi Arabia (2,010.56 per 100,000) and the lowest, in Sudan (523.29 per 100,000). The greatest increases from 1990 to 2019 in the ASIR of LEFs were noted in Yemen (132.39%), Syria (107.27%), and Afghanistan (94.47%), while the largest decreases were found in Kuwait (-62.72%), Sudan (-48.72%), and Iran (-45.37%). In 2019, the YLD rate of LEFs had increased to 277.65 per 100,000, up from 235.55 per 100,000 in 1990.

CONCLUSIONS

Between 1990 and 2019, LEFs increased in the MENA region. Violence, war, and road traffic accidents increased, leading to a high rate of fractures, especially among youth. Low bone-mineral density related to vitamin D deficiency has also been reported as a risk factor for fracture in the region. Regional health authorities should be informed of fracture patterns by this study.

Tea consumption and risk of bone health: an updated systematic review and meta-analysis

INTRODUCTION

Current research evaluating the association between tea consumption and bone health still has inconsistent findings.

MATERIALS AND METHODS

The electronic databases of Embase, PubMed, Scopus, and Web of Science were systematically searched from inception until December 2022 to identify eligible studies. The calculation of summary relative risks (RRs) and 95% confidence intervals (CIs) was carried out using random-effects models. I2 statistics and Forest plots were used to assess the heterogeneity of RR values across studies.

RESULTS

The pooled relative risks for bone health-related outcomes of interest among tea drinkers, compared to non-drinkers, were 0.910 (95% confidence interval 0.845 to 0.980) for fractures, based on 20 studies, 0.332 (0.207-0.457) for BMD (13 studies), 0.800 (0.674-0.950) for osteoporosis (10 studies), and 1.006 (0.876-1.156) for osteopenia (5 studies). Subgroup analysis of locations showed that the pooled relative risks were 0.903 (0.844-0.966) for the hip, 0.735 (0.586-0.922) for the femur, 0.776 (0.610-0.988) for the lumbar, 0.980 (0.942-1.021) for the forearm and wrist, 0.804 (0.567-1.139) for the phalanges, and 0.612 (0.468-0.800) for Ward's triangle. One-stage dose-response analysis revealed that individuals who consumed less than 4.5 cups of tea per day had a lower risk of bone health-related outcomes than those who did not consume tea, with statistically significant results.

CONCLUSION

There is an association between tea consumption and a reduced risk of fractures, osteoporosis, hip, femur, and lumbar, as well as increased BMD.

Associations of bone mineral density with sex hormone-binding globulin (SHBG) and testosterone in middle-aged Saudi men: a cross-sectional study

Objective

The present cross-sectional study examined the association between circulating levels of sex hormone-binding globulin (SHBG) and testosterone with bone mineral density (BMD) in middle-aged Arab men.

Methods

Clinical data of 103 middle-aged Saudi men (mean age 60.7±7.2) were extracted from the Osteoporosis Registry of the Chair for Biomarkers of Chronic Diseases, King Saud University in Riyadh, Saudi Arabia. Participants were categorized according to the presence of osteopenia (T-score -1.0 to -2.5) (N=47) and controls (N=56). Data collected included demographics and anthropometrics as well as levels of sex hormone-binding globulin (SHBG), testosterone and follicle-stimulating hormone (FSH) which were measured using commercially available assays. Free androgen index (FAI) was calculated.

Results

Those with osteopenia had significantly lower levels of FAI (p<0.05), and higher levels of SHBG (p<0.004) and FSH (p<0.005). In the osteopenia group, SHBG was positively correlated with age (r=0.33, p<0.05), while it was inversely correlated with BMD spine (r = -0.39, p<0.05) and T-score femur (r= -0.35, p<0.05) in the same group. Furthermore, testosterone was inversely correlated with BMI in the osteopenia group (r= -0.33, p<0.05) while FAI was positively correlated with T-score femur (r = 0.36, p<0.05) as well as in all participants (r= 0.24, p<0.05). Among controls, FAI had an inverse correlation with FSH (r= -0.28, p<0.05) and over-all (r= -0.22, p<0.05).

Conclusion

In summary, the associations elicited suggest that circulating levels of SHBG and FAI may be against age-related bone loss in middle-aged men.

Low bone mineral density, a neglected condition in North Africa and Middle East: estimates from the Global Burden of Disease Study, 1990-2019

Due to the high prevalence of low bone mineral density in North Africa and Middle East region, estimating its attributable burden would help to a better understanding of this neglected condition for policymakers and health researchers. This study presented the number of attributable deaths has doubled from 1990 to 2019.

PURPOSE

This study provides the latest estimates of the burden of low bone mineral density (BMD) from 1990 to 2019 in North Africa and Middle East (NAME) region.

METHODS

The data were extracted from the global burden of disease (GBD) 2019 study to estimate epidemiological indices such as deaths, disability-adjusted life years (DALYs), and summary exposure value (SEV). SEV is a measure of the exposure of the population to a risk factor that considers the amount of exposure by the level of risk.

RESULTS

Our findings showed that in 1990-2019, the number of deaths and DALYs attributable to low BMD had almost doubled in the region and caused 20,371 (95% uncertainty intervals: 14,848-24,374) deaths and 805,959 (630,238-959,581) DALYs in 2019. However, DALYs and death rates showed a decreasing trend after age standardization. Saudi Arabia had the highest, and Lebanon had the lowest age-standardized DALYs rates in 2019, with rates of 434.2 (329.6-534.3) and 90.3 (70.6-112.1) per 100,000, respectively. The highest burden attributable to low BMD was in the 90-94 and over 95 age groups. Also, there was a decreasing trend in age-standardized SEV to low BMD for both sexes.

CONCLUSION

Despite the decreasing trend of age-standardized burden indices, considerable amounts of deaths and DALYs were attributable to low BMD, especially in the elderly population, in the region in 2019. As the positive effects of proper interventions will be detectable in the long term, robust strategies and comprehensive stable policies are the ultimate solutions to achieving desired goals.

Prevalence and patterns of bone mineral density disorders among women in Buraidah, KSA

Objectives

Bone mineral density (BMD) disorders are disorders of bone mineralization in which bone density is reduced (T score <-1). BMD causes health and social burdens on individuals and communities. This study estimated the prevalence and determined the patterns of BMD disorders among women in Buraidah, KSA.

Methods

A cross-sectional study was conducted in 342 women visiting the DEXA Scanning Center in Buraidah. Dual-energy X-ray absorptiometry (DEXA) scan was used to measure the BMD, and cutoffs were defined based on World Health Organization criteria: normal = T score >-1, osteopenia = T score <-1 to >-2.5, and osteoporosis = T score ≤-2.5. Sociodemographic and health-related data were collected. Logistic regression was used to measure the association of various participant characteristics with BMD disorders.

Results

The mean age of the participants was 61.2 ± 7.54 years. The overall prevalence of BMD disorders was 76%, of whom 42% had osteopenia, 24% had both osteoporosis and osteopenia, and 10% had osteoporosis. Body mass index, menopause, hypertension, oral hypoglycemics, and calcium supplementation were significant predictors of BMD disorders.

Conclusions

The high prevalence of BMD disorders among women in KSA necessitates establishing and strengthening osteoporosis prevention programs to ensure healthy aging among women in KSA. Large-scale community-based studies are needed to accurately estimate the burden and risk factors of BMD disorders in the community.

The Prevalence of Osteoporosis and Osteopenia Among Older Adults in a Community-Based Setting in Riyadh, Saudi Arabia

Background Osteoporosis is a disease of bone density. It makes bones fragile and easy to break. Fragility fractures can cause significant morbidity, mortality, poor quality of life, and financial stress on medical care. Osteoporosis is overlooked and undertreated. Saudi Arabia issued a national plan promoting the early diagnosis and management of osteoporosis. Few and old studies are available in Saudi Arabia estimating the prevalence of osteoporosis in the Saudi older adult population. The aim of this study is to measure the prevalence of osteoporosis and osteopenia among older adult patients. Methodology This retrospective cross-sectional study is based on data gathered from patients ≥60 years of age. Data were collected from January 1, 2016, to December 31, 2021, for patients who were attending family medicine clinics at King Faisal Specialist Hospital & Research Centre in Riyadh, Saudi Arabia, who were screened using dual-energy X-ray absorptiometry (DEXA). Patients who have secondary causes of osteoporosis were excluded. Results A total of 1,302 patients were studied during the course of data collection. The mean age was 68.26. Out of the studied subjects, 75% were female and 25% were males. The prevalence of osteoporosis was 8.2% and 11.8% in femoral and lumbar bone mineral density (BMD) results, respectively. The prevalence of osteopenia based on femoral and lumbar BMD results was 50.2% and 41.2%, respectively. Conclusion Osteoporosis and osteopenia are prevalent in the Saudi older adult population. Multiple clinical characteristics have been associated with low bone density disease. Thus, it is important to reinforce primary care physicians' efforts for early screening and treatment of the Saudi older adult population based on their clinical and demographic risk factors.

A study of chemical Composition, Antioxidants, and volatile compounds in roasted Arabic coffee

Coffea arabica (Rubiaceae) is a basic drink for all Gulf societies, especially Saudi Arabia, it is the main part of the Saudi tradition. This investigation was carried out to track the chemical composition, caffeine content by UV–visible spectrophotometer, acrylamide content by using a gas chromatograph, free radical scavenging capacity by DPPH methods as well as determined the browning index and separated the volatiles compounds using GC–MS for the most common three degree of roasted Arabic coffee; light (180 ± 10 °C; 6.0 ± 1.0 min), medium (180 ± 10 °C; 8.0 ± 1.0 min), and dark (180 ± 10 °C; 10.0 ± 1.0 min). Data revealed that light roasted coffee has the highest significant (p < 0.05) value of moisture content (4.80%), crude protein (13.05%), and lowest value of ether extract (10.39%) and crude fiber (24.24%). The caffeine content was found to be 1.13% in light coffee, which increased to 1.17% in medium coffee, then decreased to 1.08% in dark coffee. The quantity of acrylamide detected in light roasted coffee (0.41 mg/100 g) was the greatest, whereas medium roasted coffee comparatively produced low amounts (0.31 mg/100 g). The light roasted coffee gave the highest antioxidant activity (88.72 mg TE/g), while the dark roasted coffee gave the least activity (78.76 mg TE/g). Browning index increases with roasting time. Hydrocarbons, alcohols, and esters were the most represented in roasted coffee headspace. Silanes and sec-butyl nitrite compounds were absent in the medium roasted headspace. Except for amines, all 11 classes of volatile compounds were present in the headspace of dark roasted coffee.

Osteoporosis: Is the prevalence increasing in Saudi Arabia

Background and Objective:

The objective of this analysis is to report from a teaching hospital in eastern Saudi Arabia hospital based prevalence of osteopenia and osteoporosis.

Methods:

This is a retrospective study of all patients who underwent dual-energy X-ray absorptiometry (DXA) scan between January 1, and December 31, 2018, at King Fahd Hospital of the University at Alkhobar, Saudi Arabia. Demographic data of patients, which included age, sex, diabetes mellitus status based on fasting blood sugar, hemoglobin A1C, Vitamin D level, parathormone level, and T score of the neck of femur and lumbar spine was extracted from the Quadrumed patient care system. The data was entered into database and analyzed.

Results:

Three hundred and one patients had a DXA scan for the year 2018, a jump of 27.2% of requests to diagnose osteoporosis. There were 55 (18.27%) were male and rest females (246). The average age for males was 65.2 ± 10.5 and females 62.9 ± 9.4 years. Using T score of the lumbar spine, 63.6% were osteoporotic in males and 52.8% in females.

Conclusions:

The hospital-based study shows that the prevalence of osteoporosis has significantly increased in men to 63.6%, while in postmenopausal women to 58.4%, this is high compared to the earlier reports.

Knowledge and attitudes about vitamin D and sunlight exposure in premenopausal women living in Jeddah, and their relationship with serum vitamin D levels

BACKGROUND

Saudi women are at risk of vitamin D deficiency because they are fully covered by traditional clothing and because of their indoor lifestyle. The latest national study reported that vitamin D deficiency (serum 25(OH)D < 50 nmol/L) affects 72% of young Saudi women. Because little information is available regarding knowledge on vitamin D, attitudes toward sun exposure, and the vitamin D status of premenopausal women in Jeddah, more research is necessary in order to develop effective intervention programs. The purpose of this study is to explore how the relationship between knowledge of vitamin D and attitudes about sun exposure affect the serum 25(OH)D levels in premenopausal Saudi women.

METHODS

This cross-sectional study included 257 women aged 20-50 years attending the primary care clinic in Jeddah, Saudi Arabia. Participants completed questionnaires about socio-demographics, dietary vitamin D intake, attitudes toward sun exposure, and were tested on their knowledge of vitamin D. Serum 25(OH)D was evaluated using chemiluminescent microparticle immunoassay.

RESULTS

Although 99% of participants had heard of vitamin D and 91% knew that sunlight exposure is a primary source of vitamin D, they also expressed the feeling of having insufficient knowledge regarding vitamin D sources. Furthermore, the majority of participants had negative attitudes toward sun exposure. High fish consumption was associated with a higher level of knowledge regarding vitamin D. The binary logistic regression indicated that low levels of knowledge about vitamin D were associated with low education levels (odds ratio = 0.397, 95% CI = [0.206, 0.765], p = 0.019) and with being married (odds ratio = 0.522, 95% CI = [0.281, 0.971], p = 0.04). In addition, spending time outside in the sun was significantly associated with increased serum 25(OH)D levels (p = 0.006), and the wearing of colored abaya was significantly associated with increased serum 25(OH)D levels (p = 0.008).

CONCLUSION

Suboptimal vitamin D status and insufficient knowledge of vitamin D intake sources are common in premenopausal women in Jeddah. Based on this data, health professionals could provide medical intervention to the most vulnerable female patients, as well as offer clear guidelines and information to the general public.

Yogurt, cultured fermented milk, and health: a systematic review

Consumption of yogurt and other fermented products is associated with improved health outcomes. Although dairy consumption is included in most dietary guidelines, there have been few specific recommendations for yogurt and cultured dairy products. A qualitative systematic review was conducted to determine the effect of consumption of fermented milk products on gastrointestinal and cardiovascular health, cancer risk, weight management, diabetes and metabolic health, and bone density using PRISMA guidelines. English language papers in PubMed were searched, with no date restrictions. In total, 1057 abstracts were screened, of which 602 were excluded owing to lack of appropriate controls, potential biases, and experimental design issues. The remaining 455 papers were independently reviewed by both authors and 108 studies were included in the final review. The authors met regularly to concur, through consensus, on relevance, methods, findings, quality, and conclusions. The included studies were published between 1979 and 2017. From the 108 included studies, 76 reported a favorable outcome of fermented milks on health and 67 of these were considered to be positive or neutral quality according to the Academy of Nutrition and Dietetics’ Quality Criteria Checklist. Of the 32 remaining studies, the study outcomes were either not significant (28) or unfavorable (4), and most studies (18) were of neutral quality. A causal relationship exists between lactose digestion and tolerance and yogurt consumption, and consistent associations exist between fermented milk consumption and reduced risk of breast and colorectal cancer and type 2 diabetes, improved weight maintenance, and improved cardiovascular, bone, and gastrointestinal health. Further, an association exists between prostate cancer occurrence and dairy product consumption in general, with no difference between fermented and unfermented products. This article argues that yogurt and other fermented milk products provide favorable health outcomes beyond the milk from which these products are made and that consumption of these products should be encouraged as part of national dietary guidelines.

Middle East experience from the Asia And Latin America Fracture Observational Study (ALAFOS): Baseline characteristics of postmenopausal women with osteoporosis using teriparatide

OBJECTIVE

We aimed to describe the baseline clinical characteristics and fracture history of patients taking teriparatide in routine clinical practice in the Middle East (ME) subregional cohort of the Asia and Latin America Fracture Observational Study (ALAFOS).

METHODS

Herein, we report baseline clinical characteristics of patients who were prescribed teriparatide (20 µg/day, subcutaneous injection) in four participant ME countries (Saudi Arabia, United Arab Emirates, Kuwait, and Lebanon).

RESULTS

The ME cohort included 707 patients mean (SD) age 69.3 (11.6) years. Mean (SD) bone mineral density (BMD) T-scores at baseline were -3.13 (1.28) for lumbar spine, -2.88 (0.94) for total hip, and -2.65 (1.02) for femoral neck. Osteoporotic fractures after age 40 years were reported in 45.8% (vertebral fracture 14.4%, hip fracture 18.4%) and comorbidities in 57.4% of patients. Before starting teriparatide, 19.9% of patients took other osteoporosis medications. The median (Q1; Q3) EuroQoL 5-Dimension 5-Level visual analog scale score for perceived overall health status was 70 (50; 80). Mean (SD) worst back pain in the previous 24 hours was 4.0 (3.2) using a 10-point numeric rating scale.

CONCLUSION

This analysis indicated that in ME countries, teriparatide is usually prescribed to patients with low BMD and high comorbidities, with prior fractures.

Barriers and Facilitators Associated with Physical Activity in the Middle East and North Africa Region: A Systematic Overview

Increasing physical inactivity levels in the Middle East and North Africa (MENA) region is a public health concern. We aimed to synthesize barriers and facilitators to physical activity and make appropriate recommendations to address physical inactivity. We conducted an overview of systematic reviews on physical activity barriers and facilitators in 20 MENA countries by systematically searching MEDLINE/PubMed and Google Scholar for systematic reviews published between 2008 and 2020. Our overview included four systematic reviews and 119 primary studies with data from 17 MENA countries. Lack of suitable sports facilities, time, social support and motivation, gender and cultural norms, harsh weather, and hot climate were the most commonly reported barriers to physical activity. Socio-demographic factors negatively associated with physical activity participation include advanced age, being female, less educated, and being married. Motivation to gain health benefits, losing/maintaining weight, being male, dietary habits, recreation, and increased Body Mass Index are positively associated with increased levels of physical activity. Interventions promoting physical activity in MENA should target schoolchildren, women and girls, working parents, and the elderly. Country-specific sociocultural and environmental factors influencing physical activity should be considered in the design of interventions. Current and future policies and national interventions must be consistently evaluated for effectiveness and desired outcomes.

Estimating regional bone mineral density-based T-scores using clinical information; tools validated for postmenopausal women in Sri Lanka

Objectives

This study aims to develop and validate a country specific osteoporosis risk assessing tool for Sri Lankan postmenopausal women.

Methods

Community-dwelling postmenopausal women were enrolled to development (n = 602) and validation (n = 339) samples. Clinical risk factors (CRFs) of osteoporosis were assessed. Bone mineral densities (BMD) of femoral neck, total hip and lumbar spine were assessed by dual energy X-ray absorptiometry (DXA) scan. Radial ultrasound (US) bone scan was done. Linear regression analysis was performed in development sample considering regional BMDs as dependent and CRFs as independent variables. Regression equations were developed to estimate regional BMDs using best predictive CRFs. Sensitivity, specificity, positive and negative predictive values (PPV and NPV) were assessed to validate the new tools.

Results

Age, body weight and US T-scores showed positive correlations with BMDs of all 3 sites. Two osteoporosis risk assessing tools (OPRATs) were developed as OPRAT-1 and OPRAT-2. Prevalence of osteoporosis, in the validation sample was 74.3%. Sensitivity were high in both tools (OPRAT-1 and OPRAT-2; 83.2% and 82.5%) while specificity were moderate (44.8% for both). PPV of OPRAT-1 and OPRAT-2 were 79.5% and 81.2%. Both tools showed moderate NPV (OPRAT-1 and OPRAT-2; 51% and 47%).

Conclusions

Both OPRAT-1 and OPRAT-2 have high performance in screening postmenopausal women in Sri Lanka for risk of osteoporosis. OPRAT-2 is more convenient and can be used in any healthcare setting with limited resources to identify women who will be benefitted by DXA. OPRAT-1 can be used if the radial US facility is available.

Bone Mineral Density in Severely Obese Women: Health Risk and Health Protective Risk Factors in Three Different Bone Sites

Factors associated with bone mineral density (BMD) are poorly known in severely obese individuals i.e., a body mass index (BMI) > 35 kg/m2. The objectives of this study were to describe the bone health profile of severely obese Brazilian women, to identify the health risk and health protective factors for BMD in this group and to assess whether these factors vary according to three different bone sites. BMD was assessed using dual-energy X-ray absorptiometry (DXA). This study analyzed baseline data from 104 women who had an average BMI of 43.7 ± 4.5 kg/m2 and presented the following BMD status: 1.283 ± 0.094 g/cm2 for total body, 1.062 ± 0.159 g/cm2 for vertebral column and 1.195 ± 0.134 g/cm2 for hip. They took part in the "Effect of nutritional intervention and olive oil in severe obesity" randomized clinical trial (DieTBra Trial). The risk factors negatively associated with lower BMD were age ≥50 years for the three bone sites i.e., total body, vertebral column and hip. Smoking for total body BMD (p = 0.045); BMI ≥ 50kg/m2 for vertebral column and hip; menopause for hip; high C-reactive protein (CRP) levels (p = 0.049), insufficient zinc (p = 0.010) and previous fracture for vertebral column (p = 0.007). The protective factors positively associated with BMD were physical activity (≥150 min/week (p = 0.001)) for hip; type 2 diabetes mellitus (DM2) (p < 0.0001) total body and adequate vitamin D levels from food consumption (p = 0.039) for vertebral column. A BMI ≥ 50 kg/m2 was a risk factor for lower BMD. The findings showed that protective and risk factors varied by bone site. The original study is registered with ClinicalTrials.gov. (protocol number: NCT02463435).

Health Literacy of Osteoporosis Risks among Caregivers Serving in Disability Care Facilities

Osteoporosis is a global public health issue and its consequent effects are a growing concern worldwide. Caregivers generally experience occupational physical ailments and they have less of a tendency to engage in preventive health behaviors, leading them to be in a higher risk group for osteoporosis. This study aims to present a general profile of health literacy related to osteoporosis risks and identify its associated factors among disability institutional caregivers. A cross-sectional study with a structured questionnaire was used to collect information on 465 caregivers from seven disability care institutions regarding their awareness of the health literacy related to osteoporosis risks. The results indicate that the average literacy score related to osteoporosis risks among the respondents was 60 points (full score is 80 points), with 50–59 being the most common range (51.9%), followed by 60–69 points (43.5%), and 4.4% of cases had more than 70 points. A multivariate logistic regression model revealed that respondents’ age (40–49 vs. 18–29; odds ratio (OR) = 2.53, 95% confidence interval (CI) = 1.31–4.87), education level (senior high vs. primary and junior high, OR = 2.00, 95% CI = 1.03–3.89; college and above vs. primary and junior high, OR = 3.66, 95% CI = 1.84–7.31), experience in undergoing a bone density test (OR = 1.94, 95% CI = 1.28–2.93), and poor physical fitness status (OR = 0.64, 95% CI = 0.43–0.95) were the significant predictors of the osteoporosis health literacy level. The osteoporosis health literacy of institutional caregivers is moderate, and there are many items that are worthy of attention in future health promotion programs. This study highlights risk factors related to a lower level of osteoporosis healthy literacy such as older age, less education, no experience of bone density test, and poor physical fitness that highlight the need to raise further awareness in order to improve caregivers’ bone health.

Influence of Parental Physical Activity and Screen Time on the BMI of Adult Offspring in a Saudi Population

Saudi Arabia is witnessing a drastic rise in adult obesity. Geographic limitations hamper somatic activities to counter this rise. Parental physical inactivity in the region has never been addressed. This study’s purpose is to determine the differences between parent and adult child (the subjects here) levels of physical activity (PA) and screen time (ST) between normal weight and obese adults in the Saudi Arabian population. Two hundred and forty adult subjects (18 to 35 years) were screened for their body mass index (BMI) values (18.5 ≤ 25 as normal and 25 ≤ 30) or above as overweight/obese), followed by their congregation into normal weight (N) (n = 150) and overweight/obese (Ov/Ob) (n = 90) groups. A self-reported questionnaire assessed parenting practices, while a physical activity record diary calculated existing levels of PA and ST. Statistical significance was determined by a chi-squared test (p < 0.01) and BMI correlation was found by Pearson’s correlation coefficient. Maternal age (87.8% ≤ 20 years in the Ov/Ob group (Gp) and consanguineous marriage (88.9% in the Ov/Ob Gp) showed significant differences. A high prevalence of inactivity was observed among families (father 53.3%, mother 53.3%, subject 80.0%) in the Ov/Ob Gp. Higher amounts of ST (76.7% ≥ 9 h/day) were found in the Ov/Ob Gp, which significantly differed. Differences in the parent and child levels of PA and ST exist between normal weight and obese Saudi Arabian adults. Physically active parents having adult children inspire them to develop healthy physical behaviors which counter the development of obesity. Consanguineous marriage and early maternal age may be associated with progressive adult obesity.

Association between Hypertension, Antihypertensive Drugs, and Osteoporosis in Postmenopausal Syrian Women: A Cross-Sectional Study

BACKGROUND

Osteoporosis and hypertension are frequent and often coexisting diseases among the elderly. Recent studies suggested that both diseases may share the same etiopathology. Moreover, the treatment of hypertension can affect the bone mineral density and worsen osteoporosis. The aim of this cross-sectional study was to assess the prevalence of low bone mass and osteoporosis in postmenopausal Syrian women and investigate their relationship with hypertension and antihypertensive drugs.

METHODS

813 postmenopausal women were involved in this cross-sectional study, aged between 40 and 96 yrs. Their menopause duration ranged between 1 and 43 yrs. Bone mineral density was measured using a dual-energy X-ray absorptiometry at the total lumbar spine (L1-L4) and left hip. T-score values were used to determine the diagnosis of osteoporosis. The existence of HTN was defined as blood pressure ≥130/85 mmHg or a history of hypertension medication.

RESULTS

Using the world health organization criteria, 24% had osteoporosis and 45.2% had low bone mass. The incidence of osteoporosis and low bone mass significantly increased with age and menopause duration and decreased with BMI. Prevalence of hypertension was almost equal among the women who had or did not have osteoporosis. However, hypertensive women who used thiazides or beta blockers had higher values of total lumbar BMD compared with the women who did not.

CONCLUSION

Hypertension in postmenopausal Syrian women aged over 40 was not found to be associated with osteoporosis. However, the mean total lumbar BMD of the hypertensive women who took thiazide diuretics or beta blocker was found to be increased significantly comparing to the women who did not take either.

Status of bone health and association of socio-demographic characteristics with Bone Mineral Density in Pakistani Females

Background & Objective:

The “silent thief” of bone osteoporosis is associated with various modifiable factors, identifying these factors is important in decreasing the prevalence of this highly prevalent disease. Therefore, this study was planned to identify these risk factors for osteoporosis in premenopausal and postmenopausal Pakistani women.

Methods:

A total of 1205 pre and postmenopausal females between the ages of 20 to 80 years were selected. Detailed history about the socio-demographic characteristics including age, education, profession, marital and resident status was recorded. Medical and gynecological history was also taken after informed consent Bone health of females was assessed using calcaneal ultrasound bone densitometer. SPSS 22.0 was used to analyze data.

Results:

Univariate analysis showed that age (30-39 yrs, and 60-69 yrs), occupation (housewives) and education (secondary and primary education, illiterate) were significantly associated with low bone mass density (LBMD). Multivariate analysis showed that age 30-39 years (OR=0.25 95%CI 0.13 – 0.49), age 40-49 years (OR=0.30 95%CI 0.15 – 0.59), age 50-59 years (OR=0.42 95%CI 0.22 – 0.79), primary education (OR=3.83, 95%CI 2.30 - 6.38) and illiteracy (OR=3.83 95%CI 2.52 – 5.82), were significantly associated with LBMD. The prevalence of osteopenia and osteoporosis was 29.8%, 27.2%, respectively, while 43% subjects had normal BMD.

Conclusion:

It is concluded that, within Pakistani population, the prevalence of osteopenia is high even at an early age group and the odds of having LBMD are more in less educated or illiterate women.

Physical inactivity, gender and culture in Arab countries: a systematic assessment of the literature

Background

Physical inactivity is associated with excess weight and adverse health outcomes. We synthesize the evidence on physical inactivity and its social determinants in Arab countries, with special attention to gender and cultural context.

Methods

We searched MEDLINE, Popline, and SSCI for articles published between 2000 and 2016, assessing the prevalence of physical inactivity and its social determinants. We also included national survey reports on physical activity, and searched for analyses of the social context of physical activity.

Results

We found 172 articles meeting inclusion criteria. Standardized data are available from surveys by the World Health Organization for almost all countries, but journal articles show great variability in definitions, measurements and methodology. Prevalence of inactivity among adults and children/adolescents is high across countries, and is higher among women. Some determinants of physical inactivity in the region (age, gender, low education) are shared with other regions, but specific aspects of the cultural context of the region seem particularly discouraging of physical activity. We draw on social science studies to gain insights into why this is so.

Conclusions

Physical inactivity among Arab adults and children/adolescents is high. Studies using harmonized approaches, rigorous analytic techniques and a deeper examination of context are needed to design appropriate interventions.

Vitamin D Intake among Premenopausal Women Living in Jeddah: Food Sources and Relationship to Demographic Factors and Bone Health

BACKGROUND

Saudi women depend on food sources to maintain their serum 25(OH) D concentrations because covering by traditional clothing and time spent indoors limit their sun exposure. Little is known about vitamin D intake and its main food sources in Saudi Arabia. In addition, the association between vitamin D and calcium intake and bone mineral density (BMD) in young women is not well researched.

OBJECTIVES

To assess the adequacy of vitamin D intake among Saudi women as compared to the estimated average requirements (EARs), to identify dietary vitamin D sources, to examine potential determinants of vitamin D intake, and to assess bone health and the association of calcium and vitamin D intake with BMD.

METHODS

This cross-sectional study was conducted in 257 premenopausal women aged 20-50 years in Jeddah, Saudi Arabia. Dietary vitamin D and calcium were assessed by the Semiquantitative Food Frequency Questionnaire. BMD was measured using dual-energy X-ray absorptiometry (DXA) in a subset of women (n=102) at the lumbar spine and femur neck.

RESULTS

Sixty-five percent of women were below the EAR for vitamin D, and 61% fell below the EAR for calcium. Dairy products, supplements, and fish contributed most to vitamin D intake. Increased age was an independent determinant of sufficient vitamin D intake (p < 0.001). The prevalence of osteopenia was 33% in the lumbar spine and 30% in the femur neck. There was a significant positive association between calcium intake and BMD at the lumbar spine (p=0.043) after controlling for body mass index and energy intake. Vitamin D intake was not significantly different between women with low and normal bone mass.

CONCLUSION

Premenopausal women in Jeddah have insufficient vitamin D and calcium intakes. Public health strategies to improve nutrition in young women are needed, and expanding fortification programs to include all dairy products would be useful.

Osteoporosis among hospitalized patients with proximal femoral fractures in Assiut University Trauma Unit, Egypt

The study was done to investigate osteoporosis prevalence in 275 hip fracture admissions at the Trauma Unit of Assiut University Hospitals and associated factors, which are understudied in our locality. Prevalence was 74.9%. Female sex, older age, low body mass index, and fall on the ground were associated with osteoporosis.

PURPOSE

This study aims to identify osteoporosis prevalence in hip fracture admissions at the Trauma Unit of Assiut University Hospitals and to study the independent correlates of osteoporosis-related fracture.

METHODS

A prospective cross-sectional study was carried out in 275 hip fracture patients admitted to the Trauma Unit of Assiut University Hospitals from January through December 2014 of both sexes aged 50 years and older. Exclusion criteria were polytrauma, major accidents, and history of chronic conditions and long-term medication associated with osteoporosis risk increase and bilateral hip fractures. For every patient, weight, height, and bone mineral density by dual-energy x-ray absorptiometry (DEXA) were recorded. Tests of significance for non-parametric data were used. The questionnaire included sociodemographic characteristics, dietary habits, lifestyle factors such as smoking and physical activity, and female obstetric and gynecological factors.

RESULTS

Mean age was 70.82 ± 11.02 SD; 51.6% were males and 8.4% were obese. Fall on ground was in 81.1% of fractures. Osteoporosis (femoral neck T score ≤ -2.5 SD) prevalence was 74.9%. By univariable analysis, significant correlates were female gender, older age, normal BMI, and fall on the ground. Milk and cheese daily intake was significantly associated with lower prevalence of osteoporosis. In a multivariable logistic regression model, female sex, older age, low BMI, and fall on the ground were associated with osteoporosis.

CONCLUSIONS

Osteoporosis prevalence is high among hip fracture patients and associated with female sex, increase in age, low BMI, and fall on ground. Strategies to prevent osteoporosis are needed to decrease hip fracture rates.

Association between tea consumption and osteoporosis: A meta-analysis

BACKGROUND

Previous reports have suggested a potential association of tea consumption with the risk of osteoporosis. As such association is controversial, we conducted a meta-analysis to assess the relationship between tea consumption and osteoporosis.

METHODS AND FINDINGS

We systematically searched PubMed, EMBASE and WanFang databases until March 30, 2016, using the keywords "tea and osteoporosis," without limits of language. Odds ratios (ORs) with 95% confidence intervals (95% CIs) were derived by using random-effects models throughout the analyses. We conducted the analysis of the statistical heterogeneity using Cochrane I. The funnel plot was used to speculate the publication bias, while the subgroup analysis and multiround elimination method were employed.

RESULTS

Our study was based on 17 journal articles, including 2 prospective cohort studies, 4 case-control studies, and 11 cross-sectional studies. In the present study, the total OR of osteoporosis for the highest versus the lowest categories of tea consumption was 0.62 (95% CI, 0.46-0.83), with significant heterogeneity among studies (I = 94%, P < .01). There was, however, no publication bias of the meta-analysis about tea consumption and osteoporosis. Subgroup analysis showed that tea consumption could reduce the risk of osteoporosis in all examined subgroups.

CONCLUSION

In the present study, it can be concluded from the results that tea consumption can reduce the risk of osteoporosis.

Prevalence of osteoporosis and related lifestyle and metabolic factors of postmenopausal women and elderly men: A cross-sectional study in Gansu province, Northwestern of China

The aim of this study was to investigate the osteoporosis prevalence and the risks of postmenopausal women and elderly men in Gansu province.This cross-sectional study involved 3359 postmenopausal women and 3205 elderly males who were randomly selected from 7 areas in Gansu province. Areal bone mineral density (BMD) (g/cm) was measured at the distal one-third radius of the nonstressed forearm using dual-energy X-ray absorptiometry (DXA: Osteometer MediTech). Factors related to osteoporosis were analyzed.The prevalence of osteoporosis in the entire study population was 9.65% for postmenopausal women and 8.08% for elderly males by WHO criteria, while the rate of osteopenia were 27.09% for postmenopausal women and 26.68% for elderly males. Risk of osteoporosis was significantly associated with age, menopause age, duration of menopause, body mass index (BMI), educational level, and alcohol consumption in postmenopausal women. In elderly men, age, BMI, current smoking, alcohol consumption, physical activity, and sun exposure were associated with osteoporosis. The bone turnover markers osteocalcin (OC) and C-terminal cross-linked telopeptides of type I collagen (β-CTX) were inversely correlated with BMD in both genders; serum P and 25(OH)D found no significant correlation with BMD. Serum Ca showed a positive effect on BMD in elderly men only.The osteoporosis prevalence of postmenopausal women and the men aged over 60 years in Gansu province is presented. Risk of osteoporosis was significantly associated with age, menopause age, year since menopause, BMI, and educational level in postmenopausal women. In elderly men, age, BMI, and current smoking were associated with osteoporosis. This study also found that higher OC and β-CTX level were associated with lower BMD. Poor 25(OH)D, Ca, P status were not associated with an increased risk of low BMD.

Updated association of tea consumption and bone mineral density: A meta-analysis

BACKGROUND

Current studies evaluating the association of tea consumption and bone mineral density (BMD) have yielded inconsistent findings. Therefore, we conducted a meta-analysis to assess the relationship between tea consumption and BMD.

METHODS

The PubMed, Embase, and Cochrane Library databases were comprehensively searched, and a meta-analysis performed of all observational studies assessing the association of tea consumption and BMD. Forest plots were used to illustrate the results graphically. The Q-test and I statistic were employed to evaluate between-study heterogeneity. Potential publication bias was assessed by the funnel plot.

RESULTS

Four cohort, 1 case-control, and 8 cross-sectional studies including a total of 12,635 cases were included. Tea consumption was shown to prevent bone loss [odds ratio (OR): 0.66; 95% confidence interval (CI), 0.47-0.94; P = 0.02], yielding higher mineral densities in several bones, including the lumbar spine [standardized mean difference (SMD): 0.19; 95% CI, 0.08-0.31; P = 0.001], hip (SMD: 0.19; 95% CI, 0.05-0.34; P = 0.01), femoral neck [mean difference (MD): 0.01; 95% CI, 0.00-0.02; P = 0.04], Ward triangle (MD: 0.02; 95% CI, 0.01-0.04; P = 0.001), and greater trochanter (MD: 0.03; 95% CI, 0.02-0.04; P < 0.00001), than the non-tea consumption group.

CONCLUSION

This meta-analysis provided a potential trend that tea consumption might be beneficial for BMD, especially in the lumbar spine, hip, femoral neck, Ward triangle, and greater trochanter, which might help prevent bone loss.

Low bone mineral density among young healthy adult Saudi women. Prevalence and associated factors in the age group of 20 to 36 years

Objectives:

To screen for low bone mineral density among young adult Saudi women using quantitative ultrasound (QUS) and exploring the high risk groups.

Methods:

A cross-sectional study was performed on 279, 20-36 years old female students and employees of Taibah University, Al Madinah Al Munawwarah, Kingdom of Saudi Arabia between January and May 2014. The study included bone status assessed using QUS, a structured self-reported questionnaire, anthropometric measurements, and evaluation of bone markers of bone metabolism.

Results:

The prevalence of low bone mineral density was 9%. Serum osteocalcin was found significantly higher in candidates with low bone mineral density, 20.67 ng/ml versus 10.7 ng/ml, and it was negatively correlated with T-scores. At any given point in time the exposed subjects to low calcium intake and inadequate sun exposure in the population were 11 times and 3 times more likely to have low bone mineral density, (adjusted odds ratio [OR], 11.0; 95%confidence interval [CI]=3.16, 38.34; p=0.001) and (adjusted OR, 3.32, 95%CI=1.27, 8.66, p<0.01).

Conclusion:

Early detection screening programs for low bone mineral density are needed in Saudi Arabia as it affects young Saudi women specially the high-risk group that includes young women with insufficient calcium intake and insufficient sun exposure. Serum osteocalcin as a biomarker for screening for low bone mineral density could be introduced.
