Clinical depression affects approximately 15% of community-dwelling older adults, of which half of these cases present in later life. Falls and depressive symptoms are thought to co-exist, while physical activity may protect an older adult from developing depressive symptoms. This study investigates the temporal relationships between depressive symptoms, falls, and participation in physical activities amongst older adults recently discharged following extended hospitalization.
Methods:
A prospective cohort study in which 311 older adults surveyed prior to hospital discharge were assessed monthly post-discharge for six months. N = 218 completed the six-month follow-up. Participants were recruited from hospitals in Melbourne, Australia. The survey instrument used was designed based on Fiske's behavioral model depicting onset and maintenance of depression. The baseline survey collected data on self-reported falls, physical activity levels, and depressive symptoms. The monthly follow-up surveys repeated measurement of these outcomes.
Results:
At any assessment point, falls were positively associated with depressive symptoms; depressive symptoms were negatively associated with physical activity levels; and, physical activity levels were negatively associated with falls. When compared with data in the subsequent assessment point, depressive symptoms were positively associated with falls reported over the next month (unadjusted OR: 1.20 (1.12, 1.28)), and physical activity levels were negatively associated with falls reported over the next month (unadjusted OR: 0.97 (0.96, 0.99) household and recreational), both indicating a temporal relationship.
Conclusion:
Falls, physical activity, and depressive symptoms were inter-associated, and depressive symptoms and low physical activity levels preceded falls. Clear strategies for management of these interconnected problems remain elusive.
To examine the use of nutrition and health claims on packaged foods commonly eaten in Ireland.
Design
An assessment of the labels of packaged food products that are commonly eaten in Ireland to determine the level of use of nutrition and health claims. Where present, the exact text of the claims as observed was recorded for seventeen different food categories and the claims categorised in accordance with EU Regulation 1924/2006 on nutrition and health claims made on foods.
Setting
Four retailers in Dublin, Ireland.
Results
Of the foods surveyed, 47·3 % carried a nutrition claim and 17·8 % carried a health claim. Frozen fruit & vegetables and Breakfast cereals were the food categories with the highest proportion of nutrition claims. The most widespread nutrition claim was that referring to ‘fat’ and, within this group, the most commonly used text was ‘low fat’. The largest category of health claims observed in the present survey was general health claims. Claims referring to the digestive system were the most common followed by claims that a product will ‘lower/reduce/regulate your cholesterol’. Yoghurt & yoghurt drinks was the food category with the highest proportion of health claims, of which improving or boosting the digestive system was the most common.
Conclusions
The use of nutrition and health claims on the Irish market is widespread. EU Regulation 1924/2006 requires monitoring of the market for these types of claims. The current study could provide baseline data for the food industry and regulators to monitor the development of this market in the future.
