1.  Frailty and Fracture, Disability, and Falls: A Multiple Country Study from the Global Longitudinal Study of Osteoporosis in Women (GLOW) 
Objectives
To test whether women age ≥ 55 years with increasing evidence of a frailty phenotype would have greater risk of fractures, disability, and recurrent falls, compared with women who were not frail, across geographic areas (Australia, Europe, and North America) and age groups.
Design
Multinational, longitudinal, observational cohort study.
Setting
The Global Longitudinal Study of Osteoporosis in Women (GLOW).
Participants
Women (n=48,636) age ≥ 55 years enrolled at sites in Australia, Europe, and North America.
Measurements
Components of frailty (slowness/weakness, poor endurance/exhaustion, physical activity, and unintentional weight loss) at baseline and report of fracture, disability, and recurrent falls at 1 year of follow-up were investigated. Women also reported health and demographic characteristics at baseline.
Results
Among those age < 75 years, women from the United States were more likely to be prefrail and frail than women from Australia/Canada, and Europe. The distribution of frailty was similar by region for women age ≥ 75 years. Odds ratios from multivariable models for frailty versus non frailty were 1.23 (95% CI = 1.07–1.42) for fracture, 2.29 (95% CI = 2.09–2.51) for disability, and 1.68 (95% CI = 1.54–1.83) for recurrent falls. The associations for pre-frailty versus non frailty were weaker but still indicated statistically significant increased risk for each outcome. Overall, associations between frailty status and each outcome were similar across age and geographic region.
Conclusion
Increased evidence of a frailty phenotype is associated with increased risk for fracture, disability, and falls among women age ≥ 55 years in 10 countries, with similar patterns across age and geographic region.

3.  Diet and its relationship with grip strength in community-dwelling older men and women: the Hertfordshire Cohort Study 
OBJECTIVES
To examine relationships between diet and grip strength in older men and women, and to determine whether these relationships are modified by prenatal growth.
DESIGN
Cross-sectional and retrospective cohort study
SETTING
Hertfordshire, UK
PARTICIPANTS
Two thousand, nine hundred and eighty three men and women aged 59 to 73 years who were born and still live in Hertfordshire, UK
MEASUREMENTS
Weight at birth recorded in Health Visitor ledgers. Current food and nutrient intake assessed using an administered food frequency questionnaire, grip strength was measured with a hand-held dynamometer.
RESULTS
Grip strength was positively associated with height and weight at birth, and inversely related to age (all P<0.001). Of the dietary factors considered in relation to grip strength, the most important was fatty fish consumption. An increase in grip strength of 0.43kg (95% CI 0.13 to 0.74) in men (P=0.005), and 0.48kg (95% CI 0.24 to 0.72) in women (P<0.001), was observed for each additional portion of fatty fish consumed per week. These relationships were independent of adult height, age and birth weight, each of which had additive effects on grip strength. There was no evidence of interactive effects of weight at birth and adult diet on grip strength.
CONCLUSION
These data suggest that fatty fish consumption can have an important influence on muscle function in older men and women. This raises the possibility that the anti-inflammatory actions of n-3 fatty acids may play a role in the prevention of sarcopenia.
