Ho VWT, Chua KY, Song X, Jin A, Koh WP. Reproductive factors and risk of physical frailty among Chinese women living in Singapore. J Nutr Health Aging 2024; 28:100226. [PMID: 38593634 DOI: 10.1016/j.jnha.2024.100226] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/19/2023] [Revised: 03/23/2024] [Accepted: 03/29/2024] [Indexed: 04/11/2024]
Abstract
SETTING Although age at menopause has been linked to higher risk of physical frailty in later life, little is known about other reproductive factors. OBJECTIVES Our study aimed to investigate the associations between 1) age at menarche, 2) age at natural menopause, 3) duration of reproductive period, 4) number of children, 5) use of oral contraceptives (OCP), and 6) use of hormone replacement therapy (HRT) with the risk of physical frailty in late life. DESIGN We used data from 5934 women of the Singapore Chinese Health Study who experienced natural menopause, and participated in the third follow-up interviews when physical frailty was assessed. Logistic regression was used to evaluate association of reproductive factors evaluated during baseline and prior follow-up interviews with physical frailty at follow-up 3. PARTICIPANTS Community-dwelling Chinese women living in Singapore. Participants had a mean age of 52.6 years at baseline (1993-1998), and a mean age of 72.8 years during the third follow-up (2014-2017). MEASUREMENTS Sociodemographic characteristics, level of education, smoking history, physical activity, and history of physician-diagnosed comorbidities were collected. Participants' weight and height were self-reported. We used a modified Cardiovascular Health Study phenotype to assess physical frailty. RESULTS Age at menarche was inversely associated with the likelihood of physical frailty (Ptrend = 0.001); each one-year decrease in age at menarche was associated with a 9% increase (95% CI: 4%-14%) in odds of physical frailty. Age at menopause was also inversely associated with the likelihood of physical frailty (Ptrend = 0.009); every one-year decrease in age at menopause was associated with 2% (0%-4%) increased odds. In the assessment of frailty, younger ages at menarche and menopause were associated with greater likelihood of being in the slowest quintile for timed up-and-go and weakest quintile for handgrip strength. Conversely, duration of reproductive period, parity, and use of oral contraceptives or hormone replacement therapy were not significantly associated with the likelihood of physical frailty. CONCLUSIONS In our population-based cohort of Chinese women, younger ages at menarche and menopause were associated with higher likelihood of physical frailty in later life.

Abstract
OBJECTIVE Assess the association between combined hormonal contraceptives (CHC) use and musculoskeletal tissue pathophysiology, injuries or conditions. DESIGN Systematic review with semiquantitative analyses and certainty of evidence assessment, guided by the Grading of Recommendations Assessment, Development and Evaluation approach. DATA SOURCES MEDLINE, EMBASE, CENTRAL, SPORTDiscus, CINAHL searched from inception to April 2022. ELIGIBILITY Intervention and cohort studies that assessed the association between new or ongoing use of CHC and an outcome of musculoskeletal tissue pathophysiology, injury or condition in postpubertal premenopausal females. RESULTS Across 50 included studies, we assessed the effect of CHC use on 30 unique musculoskeletal outcomes (75% bone related). Serious risk of bias was judged present in 82% of studies, with 52% adequately adjusting for confounding. Meta-analyses were not possible due to poor outcome reporting, and heterogeneity in estimate statistics and comparison conditions. Based on semiquantitative synthesis, there is low certainty evidence that CHC use was associated with elevated future fracture risk (risk ratio 1.02-1.20) and total knee arthroplasty (risk ratio 1.00-1.36). There is very low certainty evidence of unclear relationships between CHC use and a wide range of bone turnover and bone health outcomes. Evidence about the effect of CHC use on musculoskeletal tissues beyond bone, and the influence of CHC use in adolescence versus adulthood, is limited. CONCLUSION Given a paucity of high certainty evidence that CHC use is protective against musculoskeletal pathophysiology, injury or conditions, it is premature and inappropriate to advocate, or prescribe CHC for these purposes.

Abstract
Objectives Hormonal reproductive factors have been considered to play an important role in the etiology of osteoarthritis (OA). We performed Mendelian randomization (MR) to examine whether a causal effect existed between them. Methods MR was performed by using publicly released genome-wide association study (GWAS) summary statistics to estimate the causal associations of three relevant exposures, including age at menarche (AAM), age at natural menopause (ANM) and age at first birth (AFB), with the risk of OA. We employed several MR methods, including inverse-variance weighted (IVW), MR-Egger regression, weighted median and weighted mode, to estimate the causality. We performed a sensitivity analysis by manually pruning pleiotropic variants associated with the known confounder body mass index (BMI). Results The instrumental variables that achieved genome-wide significance, including 349 AAM single nucleotide polymorphisms (SNPs), 121 AAM SNPs, 54 ANM SNPs, and 10 AFB SNPs, were incorporated into the operation. IVW analysis indicated that each additional year in AFB was associated with a decreasing risk of hip and/or knee OA and overall OA (hip and/or knee OA: OR = 0.79, 95% CI: 0.64-0.93, P = 1.33 × 10-3; overall OA: OR = 0.80, 95% CI: 0.68-0.92, P = 1.80 × 10-4). In addition, our results suggested that AAM exerted a causal effect on knee OA in an unfavorable manner (OR = 0.86, 95% CI: 0.76-0.95, P = 1.58 × 10-3). After accounting for the effect of BMI, the causal effect association between AFB and hip and/or knee OA was also examined (IVW: OR = 0.78, 95% CI: 0.66-0.92, P = 3.22 × 10-3). Conclusion Our findings add a growing body of evidence surrounding the unfavorable effects of early AFB on OA risk, suggesting the essential for relevant health problem management in susceptible populations.

Female reproductive factors and risk of joint replacement arthroplasty of the knee and hip due to osteoarthritis in postmenopausal women: a nationwide cohort study of 1.13 million women. Osteoarthritis Cartilage 2022; 30:69-80. [PMID: 34774788 DOI: 10.1016/j.joca.2021.10.012] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/02/2021] [Revised: 10/10/2021] [Accepted: 10/25/2021] [Indexed: 02/02/2023]
Abstract
OBJECTIVES Previous studies of the relationships between female reproductive factors and osteoarthritis (OA) have shown conflicting results. In this study, we aimed to explore the relationships between reproductive factors and joint replacement arthroplasty of the knee (TKRA) and hip (THRA) in a large nationwide population-based cohort of postmenopausal Korean women. METHODS We included 1,134,680 subjects who participated in national health examinations in 2009 in the study. The study outcomes were incident THRA or TKRA due to severe hip or knee OA. The relationships between reproductive factors and THRA or TKRA were evaluated using a multivariable-adjusted proportional hazards model. RESULTS During a mean follow-up duration of 8.2 years, 1,610 incident THRA cases and 60,670 incident TKRA cases were observed. Later age at menarche, longer breastfeeding, HRT and OC use were associated with increased risk of TKRA for severe knee OA, while later age at menopause and longer reproductive span were associated with decreased risk. With regard to THRA for severe hip OA, later menarche, longer breastfeeding, HRT more than 5 years, and OC use more than 1 year were associated with higher risk. The associations between reproductive factors and severe OA were more pronounced in underweight and younger subjects. CONCLUSION We found that shorter estrogen exposure was associated with higher risk of TKRA due to severe knee OA, and such associations were more pronounced in underweight and younger subjects. The association between shorter estrogen exposure and THRA was not robust.

RMD Open 2021; 7:rmdopen-2021-001602. [PMID: 34330847 PMCID: PMC8327838 DOI: 10.1136/rmdopen-2021-001602] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/28/2021] [Accepted: 06/13/2021] [Indexed: 11/22/2022] Open
Abstract
Objectives We aimed to evaluate the association between fibre intake and its food sources, and the risk of total knee replacement (TKR) due to severe knee osteoarthritis (KOA). Methods We used data from the Singapore Chinese Health Study, a prospective cohort study that recruited 63 257 participants aged 45–74 years from 1993 to 1998. At baseline, we assessed diet using a validated 165-item semiquantitative food frequency questionnaire, together with body mass index (BMI) and lifestyle factors. Incident TKR cases were identified via record linkage with nationwide hospital discharge database through 2017. Results There were 2816 cases of incident TKR due to severe KOA. The total fibre intake at baseline was not associated with the risk of TKR after adjustment for confounders. Among the food sources of fibre, higher intake of legumes was associated with a lower risk of TKR in a dose-dependent manner; compared with those having the lowest quartile intake, HR (95% CI) was 0.86 (0.76, 0.96) for those having the highest quartile intake (p for trend=0.004). This association was consistent after including BMI in the model and homogeneous across BMI categories. The consumption of other fibre sources, namely grain products, nuts and seeds, soy food, fruits and vegetables, was not associated with the risk of TKR. Conclusion Intake of legumes, but not total fibre, was associated with a reduced risk of TKR. Further research is needed to replicate our findings and to evaluate possible biological mechanisms that could explain the effect of dietary legumes on pathogenesis or progression of KOA.

Impact of parity on biomechanical risk factors for knee OA initiation. Gait Posture 2021; 84:287-292. [PMID: 33418454 DOI: 10.1016/j.gaitpost.2020.12.024] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/16/2020] [Revised: 12/18/2020] [Accepted: 12/21/2020] [Indexed: 02/02/2023]
Abstract
BACKGROUND Women are twice as likely as men to develop knee osteoarthritis (OA), and with it experience greater losses of physical function and disability. A change in the mechanical environment of the joint is a key initiating factor for knee OA. Differences in morphology, joint injury risk, and hormonal shifts in mid-life are often considered factors which increase OA risk for women. Pregnancy, a time of significant hormonal, morphological, and biomechanical change, has received comparably less attention. If morphological and biomechanical changes persist postpartum, this could increase OA risk for parous (childbearing) women. RESEARCH QUESTION Are lower limb gait mechanics different between healthy nulliparous (non-childbearing) and parous (childbearing) women? METHODS Twenty-eight self-reported not pregnant female participants (14 parous, 14 nulliparous) were recruited for the study. Nulliparous participants had never given birth to a child. Parous participants had given birth to at least one full-term infant (37-42 weeks) without complications between one to five years before data collection. Motion capture of participants' preferred, fast, and set (1.4 m/s) walking speeds was conducted. Repeated measures ANOVA were performed to test for significant group differences in joint kinematics and kinetics. RESULTS There was a significant main effect of group indicating a larger knee flexion angle at toe off (p = 0.0002), smaller knee extension moment at heel strike (p = 0.0006), smaller first peak knee flexion moment (p = 0.040), and smaller peak hip adduction moment for the parous group compared to the nulliparous group (p = 0.003). Static Q-angle did not differ between groups. SIGNIFICANCE Alteration in mechanics from the habitual loading pattern are thought to increase risk of OA. Smaller knee moments in post-partum women could alter the mechanical stimulus to cartilage, and should be investigated in conjunction with cartilage health measures to determine the link with OA initiation.

Int J Rheum Dis 2020; 23:569-575.

Abstract
AIM Early research found innate immune factor complement C3 in the synovial fluid (SF) and activated in serum of osteoarthritis (OA) patients. Whether synovial C3 comes from circulation, or is produced locally, is still unknown. It is also unclear whether synovial and circulating C3 is responsible to OA symptoms. A native C3 molecule consists of two chains, C3-α and C3-β. Small fragments breaking down from C3-α chain in serum and SF were reported to be related to OA severity. Little is known if C3-β chain is involved in the pathogenesis. METHOD In this study, we evaluated these important areas by biochemical analyses of C3-α and C3-β chains in both the SF and plasma of OA patients. RESULTS Our results showed that C3-α and C3-β levels in SF did not correlate with those in plasma, suggesting that synovial C3 is independently and locally produced, rather than being "leaked" from circulation. Synovial C3-β but not C3-α levels correlated with pain, other OA symptoms, function in daily living, and sports/recreational activities. Plasma C3-β levels only marginally correlated with pain, and plasma C3-α levels did not correlate with any of these OA symptoms. CONCLUSION We present first-hand evidence that the clinical symptoms of OA are mainly associated with C3 in the local SF rather than systemic circulation, suggesting local factors in the etiopathogenesis. Future local targeted therapies for pain management may be more effective and safer.
