Hip fracture incidence in Malaysia 1981-1989

Lee CM, Sidhu JS, Pan KL

Acta Orthop Scand, 1993 Apr;64(2):178-80.
PMID: 8498181 DOI: 10.3109/17453679308994565

The age-corrected incidence of hip fracture in the city of Kuala Lumpur and the surrounding districts has increased from 1981 to 0.7 per 1,000 population in 1989. Women dominated by a factor of 1.3. The mean age was 73 (50-103) years. The increased rate observed was attributed solely to trochanteric fractures among those 70 years and above. There were differences in the various parameters among the different races. The fracture incidence and woman/man ratio were substantially lower than has been reported from developed countries.

Fulltext Proton Pump Inhibitors and Fracture Risk: A Review of Current Evidence and Mechanisms Involved

Thong BKS, Ima-Nirwana S, Chin KY

Int J Environ Res Public Health, 2019 May 05;16(9).
PMID: 31060319 DOI: 10.3390/ijerph16091571

The number of patients with gastroesophageal problems taking proton pump inhibitors (PPIs) is increasing. Several studies suggested a possible association between PPIs and fracture risk, especially hip fractures, but the relationship remains contentious. This review aimed to investigate the longitudinal studies published in the last five years on the relationship between PPIs and fracture risk. The mechanism underlying this relationship was also explored. Overall, PPIs were positively associated with elevated fracture risk in multiple studies (n = 14), although some studies reported no significant relationship (n = 4). Increased gastrin production and hypochlorhydria are the two main mechanisms that affect bone remodeling, mineral absorption, and muscle strength, contributing to increased fracture risk among PPI users. As a conclusion, there is a potential relationship between PPIs and fracture risks. Therefore, patients on long-term PPI treatment should pay attention to bone health status and consider prophylaxis to decrease fracture risk.

PMID: 11420781

In this population-based study, we determined the incidence rates of hip fracture among Singapore residents aged 50 years and above. Information was obtained from a centralized database system which captured admissions with the primary diagnosis of a closed hip fracture (ICD-9 codes 820, 820.0, 820.2 and 820.8, n = 12,927) from all health care establishments in the country from 1991 to 1998 inclusive. After removing duplicates, hospital transfers, readmissions and non-acute care admissions, the total number of hip fractures was 9406. Based on the national population census 1990 (n = 464,100) and yearly population estimates, the age-adjusted hip fracture rates for 1991-1998 (per 100,000) were 152 in men and 402 in women. This was 1.5 and over 5 times higher than corresponding rates in the 1960s. From 1991 to 1998, these hip fracture rates tended to increase by 0.7% annually in men and by 1.2% annually in women. Among the three major racial groups, in men, the Chinese had significantly higher age-adjusted hip fracture rates (per 100,000): 168 (95% confidence interval (CI) 158-178) compared with 128 (95% CI 105-152) for Indians and 71 (95% CI 54-88) for Malays. A similar pattern occurred in women: 410 (95% CI 395-425), for Chinese compared with 361 (95% CI 290-432) for Indians and 264 (95% CI 225-303) for Malays. Since the 1960s, the main increases in hip fracture rates have been seen in the Chinese and Malays, with the rates in Indians appearing to decrease. Hip fracture incidence rates in Singapore have risen rapidly over the past 30-40 years, particularly in women, and are now among the highest in Asia. Significant racial differences in hip fracture rates occur within the same community. Time trends in hip fracture rates differed between races.

The incidence of hip fracture in four Asian countries: the Asian Osteoporosis Study (AOS)

Lau EM, Lee JK, Suriwongpaisal P, Saw SM, Das De S, Khir A, et al.

Osteoporos Int, 2001;12(3):239-43.
PMID: 11315243 DOI: 10.1007/s001980170135

The Asian Osteoporosis Study (AOS) is the first multicenter study to document and compare the incidence of hip fracture in four Asian countries. Hosital discharge data for the year 1997 were obtained for the Hong Kong SAR, Singapore, Malaysia and Thailand (Chiang Mai). The number of patients who were 50 years of age and older and who were discharged with a diagnosis of hip fracture (ICD9 820) was enumerated. The age-specific incidence rates were deduced and were directly adjusted to the US white population in 1989. The age-adjusted rates for men and women (per 100,000) are as follows: Hong Kong, 180 and 459; Singapore, 164 and 442; Malaysia, 88 and 218; Thailand, 114 and 289; compared with US White rates of 187 in men and 535 in women, published in 1989. We conclude that there is moderate variation in the incidence of hip fracture among Asian countries. The rates were highest in urbanized countries. With rapid economic development in Asia, hip fracture will prove to be a major public health challenge.

Fulltext Bone mineral densities and hip axis lengths of normal Singapore women

Ng CED, Sundram F, Mahbub UR, Hoon P

Med J Malaysia, 1999 Jun;54(2):180-4.
PMID: 10972027

This study aims to evaluate the bone mineral densities and hip axis lengths of women in the local population. 227 normal Singapore women of ages 20 to 70 years had evaluation of their bone mineral densities (BMDs) by means of dual X-ray absorptiometry (DXA). The trend of BMDs at the left femoral neck and the lumbar spine remains fairly constant with increasing age until the 45-49 years age-band, beyond which there is a consistent decline. The mean hip axis length is 10.3 cm with a standard deviation of 0.6 cm. In general, the bone mineral densities in the femoral neck and lumbar spine as measured by DXA and the hip axis length of the local population is lower than corresponding figures reported in the Western population.

Fracture risk prediction in post-menopausal women with osteopenia and osteoporosis: preliminary findings

Nik Mohd Hatta NNK, Lokman M, Said N M, Daud A, Ibrahim M, Sharifudin MA, et al.

Enferm Clin, 2018 Feb;28 Suppl 1:232-235.
PMID: 29650194 DOI: 10.1016/S1130-8621(18)30074-3

OBJECTIVE: The study aims to identify the risk of obtaining a fracture among post-menopausal women with osteopenia and osteoporosis.

METHOD: This work was a cross-sectional study involving a purposive sample of 87 post-menopausal women who attended the orthopedic and menopause clinics of Hospital Tengku Ampuan Afzan, Kuantan. The data were entered into the WHO fracture risk assessment tool (FRAX®) to predict major fracture and risk for hip fracture in 10 years' time.

RESULTS: The mean age of the respondents was 61.6 years (SD=7.9). Among the respondents, 50.6% had osteopenia and nearly half (48.3%) had osteoporosis. The mean number of menopausal years of the respondents was 11.9 (SD=8.5), ranging between 1 and 44 years. The FRAX findings indicated 9.7% major osteoporotic fracture probability and 3.5% hip fracture probability, which were denoted as high risk. A Pearson correlation coefficient was computed to assess the relationship between menopausal years and the FRAX major osteoporotic fracture probability. A significant positive correlation was found between the two, but the correlation was weak (r=0.581, n=87, p < 0.001).

CONCLUSIONS: The present findings indicate that menopausal years have a positive correlation with the risk of obtaining a fracture.

Study site: orthopedic and menopause clinics of Hospital Tengku Ampuan Afzan, Kuantan.

Fulltext The impact of lockdown during the COVID-19 pandemic on osteoporotic fragility fractures: an observational study

Ogliari G, Lunt E, Ong T, Marshall L, Sahota O

Arch Osteoporos, 2020 10 07;15(1):156.
PMID: 33026586 DOI: 10.1007/s11657-020-00825-1

We investigated whether osteoporotic fractures declined during lockdown, among adults aged 50 years and older. We showed that fewer outpatients attended the Fracture Clinic, for non-hip fractures, during lockdown; in contrast, no change in admissions for hip fractures was observed. This could be due to fewer outdoors falls, during lockdown.
PURPOSE: Many countries implemented a lockdown to control the spread of the COVID-19 pandemic. We explored whether outpatient attendances to the Fracture Clinic for non-hip fragility fracture and inpatient admissions for hip fracture declined during lockdown, among adults aged 50 years and older, in a large secondary care hospital.
METHODS: In our observational study, we analysed the records of 6681 outpatients attending the Fracture Clinic, for non-hip fragility fractures, and those of 1752 inpatients, admitted for hip fracture, during the time frames of interest. These were weeks 1st to 12th in 2020 ("prior to lockdown"), weeks 13th to 19th in 2020 ("lockdown") and corresponding periods over 2015 to 2019. We tested for differences in mean numbers (standard deviation (SD)) of outpatients and inpatients, respectively, per week, during the time frames of interest, across the years.
RESULTS: Prior to lockdown, in 2020, 63.1 (SD 12.6) outpatients per week attended the Fracture Clinic, similar to previous years (p value 0.338). During lockdown, 26.0 (SD 7.3) outpatients per week attended the Fracture Clinic, fewer than previous years (p value < 0.001); similar findings were observed in both sexes and age groups (all p values < 0.001). During lockdown, 16.1 (SD 5.6) inpatients per week were admitted for hip fracture, similar to previous years (p value 0.776).
CONCLUSION: During lockdown, fewer outpatients attended the Fracture Clinic, for non-hip fragility fractures, while no change in inpatient admissions for hip fracture was observed. This could reflect fewer non-hip fractures and may inform allocation of resources during pandemic.

Fulltext The association between various visual function tests and low fragility hip fractures among the elderly: a Malaysian experience

Chew FL, Yong CK, Mas Ayu S, Tajunisah I

Age Ageing, 2010 Mar;39(2):239-45.
PMID: 20065356 DOI: 10.1093/ageing/afp259

BACKGROUND: hip fractures are an increasing source of morbidity and mortality in older people. The role of visual function tests such as visual impairment, stereopsis, contrast sensitivity and visual field defects in low fragility hip fractures in Asian populations is not well understood.
OBJECTIVE: to determine the association between various visual function tests and low fragility hip fractures in an Asian population.
DESIGN: case-control study.
SETTING: University Malaya Medical Centre, Kuala Lumpur, Malaysia.
SUBJECTS: 108 cases aged > or = 55 years admitted with low fragility fractures and 108 controls (matched for age, gender and race).
METHODS: both cases and controls underwent a detailed ophthalmological examination, which included visual acuity, stereopsis, contrast sensitivity and visual field testing.
RESULTS: poorer visual acuity (odds ratio, OR = 4.08; 95% confidence interval, CI: 1.44, 11.51), stereopsis (OR = 3.60, 95% CI: 1.55, 8.38), contrast sensitivity (OR = 3.34, 95% CI: 1.48, 7.57) and visual field defects (OR = 11.60, 95% CI: 5.21, 25.81) increased the risk of fracture. Increased falls were associated with poorer visual acuity (OR = 2.30, 95% CI: 1.04, 5.13), stereopsis (OR = 2.11, 95% CI: 1.03, 4.32), contrast sensitivity (OR = 2.12, 95% CI: 1.05, 4.30) and visual field defects (OR = 3.40, 95% CI: 1.69, 6.86).
CONCLUSION: impaired visual acuity, stereopsis, contrast sensitivity and visual field defects are associated with an increased risk of low fragility hip fractures. We recommend that all patients aged > or = 55 should have an annual ophthalmological examination that includes visual acuity, contrast sensitivity, stereopsis and visual field testing to assess the risks for falls and low fragility fractures.

Fulltext Risk factors for hip fracture in Asian men and women: the Asian osteoporosis study

Lau EM, Suriwongpaisal P, Lee JK, Das De S, Festin MR, Saw SM, et al.

J. Bone Miner. Res., 2001 Mar;16(3):572-80.
PMID: 11277276 DOI: 10.1359/jbmr.2001.16.3.572

The objectives of the Asian Osteoporosis Study (AOS) were to determine risk factors for hip fracture in men and women in four Asian countries, that is, Singapore, Malaysia, Thailand, and the Philippines. A total of 451 men and 725 women (aged 50 years and over) with hip fractures were compared with an equal number of community controls. A standardized questionnaire was administered by interview. The following relative risks (RRs) were found in women and men by multiple logistic regression: dietary calcium intake < 498 mg/day, 2.0 for women (95% CI, 1.5-2.8) and 1.5 for men (95% CI, 1.0-2.2); no load bearing activity in the immediate past, 2.0 for women (95% CI, 1.4-2.7) and 3.4 for men (95% CI, 2.3-5.1); no vigorous sport activities in young adulthood, 7.2 for women (95% CI, 4.0-13.0) and 2.4 for men (95% CI, 1.6-3.6); cigarette smoking, 1.5 for men (95% CI, 1.0-2.1); alcohol consumption 7 days a week, 2.9 for women (95% CI, 1.0-8.6) and 1.9 for men (95% CI, 1.1-3.2); fell twice or more in the last 12 months, 3.0 for women (95% CI, 1.8-4.8) and 3.4 for men (95% CI, 1.8-6.6); a history of fractures after 50 years of age, 1.8 for women (95% CI, 1.1-2.9) and 3.0 for men (95% CI, 1.6-5.6); a history of stroke, 3.8 for women (95% CI, 2.0-7.1) and 3.6 for men (95% CI, 1.8-7.1); use of sedatives, 2.5 for women (95% CI, 1.0-6.3) and 3.0 for men (95% CI, 1.0-9.7); and use of thyroid drugs, 7.1 for women (95% CI, 2.0-25.9) and 11.8 for men (95% CI, 1.3-106.0). Women who were 1.56 m or taller had an RR of 2.0 (95% CI, 1.3-3.0) for hip fracture and men who were 1.69 m or taller had an RR of 1.9 (95% CI, 1.2-3.1) for hip fracture. Based on these findings, primary preventive programs for hip fracture could be planned in Asia.
