Low handgrip strength, a simple and inexpensive test could be considered in clinical settings for identifying future falls and fractures. ALM/ body mass index could be most suitable in estimating 10-year mortality risk, but requires specialised equipment.

IntroductionPrevious studies in Nigeria have documented significant association between maternal education and child immunization. However, little is known about the pathway through which maternal education improves immunization uptake. This study aims to examine whether maternal literacy and socioeconomic status mediates the relationship between maternal education and complete immunization coverage in children.MethodsNationally representative data from the first wave of the Nigeria General Household Survey-Panel were used, which includes 661 children aged one year and below. Regression analyses were used to model the association between maternal education and child's immunization uptake; we then examined whether maternal literacy and household economic status mediates this association.ResultsOf the 661 children, 40% had complete immunization. The prevalence ratio (PR) of complete immunization in children whose mothers were educated versus those whose mothers were not educated was 1.44 (95% CI: 1.16-1.77). Maternal literacy substantially reduced the estimated association between maternal education and complete immunization by 90%, whereas household economic status reduced the estimates by 27%.ConclusionThese findings suggest that complete immunization was higher in children whose mothers were educated, partly because maternal education leads to acquisition of literacy skills and better health-seeking behavior which then improves immunization uptake for their children. Socioeconomic status is an alternative pathway but with less substantial indirect effect.

Background Sarcopenia is an age-associated skeletal muscle condition characterized by low muscle mass, strength, and physical performance. There is no international consensus on a sarcopenia definition and no contemporaneous clinical and research guidelines specific to Australia and New Zealand. The Australian and New Zealand Society for Sarcopenia and Frailty Research (ANZSSFR) Sarcopenia Diagnosis and Management Task Force aimed to develop consensus guidelines for sarcopenia prevention, assessment, management and research, informed by evidence, consumer opinion, and expert consensus, for use by health professionals and researchers in Australia and New Zealand. Methods A four-phase modified Delphi process involving topic experts and informed by consumers, was undertaken between July 2020 and August 2021. Phase 1 involved a structured meeting of 29 Task Force members and a systematic literature search from which the Phase 2 online survey was developed (Qualtrics). Topic experts responded to 18 statements, using 11-point Likert scales with agreement threshold set a priori at >80%, and five multiple-choice questions. Statements with moderate agreement (70%-80%) were revised and re-introduced in Phase 3, and statements with low

Background The contribution of cerebral small vessel disease (cSVD) to the pathogenesis of frailty remains uncertain. We aimed to examine the associations between cSVD with progression of frailty in a population-based study of older people. Methods People aged between 60 and 85 years were randomly selected form the electoral roll to participate in the Tasmanian Study of Cognition and Gait. Participants underwent self-reported questionnaires, objective gait, cognitive and sensorimotor testing over three phases ranging between 2005 and 2012. These data were used to calculate a 41-item frailty index (FI) at three time points. Baseline brain magnetic resonance imaging was performed on all participants to measure cSVD. Generalized mixed models were used to examine associations between baseline cSVD and progression of frailty, adjusted for confounders of age, sex, level of education, and total intracranial volume. Results At baseline (n = 388) mean age was 72 years (SD = 7.0), 44% were female, and the median FI score was 0.20 (interquartile range [IQR] 0.12, 0.27). In fully adjusted models higher burden of baseline white matter hyperintensity (WMH) was associated with frailty progression over 4.4 years (β = 0.03, 95% CI: 0.01, 0.05; p = .004) independent of other SVD markers. Neither baseline infarcts (p = .23), nor microbleeds at baseline (p = .65) were associated with progression of frailty. Conclusions We provide evidence for an association between baseline WMHs and progression of frailty. Our findings add to a growing body of literature suggesting WMH is a marker for frailty.
