Prior studies have found evidence of a relationship between food insecurity and functional limitations among older populations in the USA.

This is a longitudinal investigation of food security in relation to functional limitations, assessed as Activities of Daily Living (ADL) and Instrumental Activities of Daily Living (IADL) scores.

The Greater Boston, MA area.

1461 Boston Puerto Rican Health study participants, predominantly (70·5 %) female and aged 57·1 years (sd ± 7·6) at baseline followed for 6·2 (sd ± 0·98) years.

In cross-sectional analysis at baseline, participants reporting severe food insecurity had greater functional limitations (higher ADL; β = 2·34; 95 % CI (1·48, 3·19)) and higher IADL (β = 1·17, 95 % CI (0·68, 1·65)) compared with food secure participants. In longitudinal linear mixed models, severely food insecure participants at baseline had greater functional limitations over 5 years, as assessed by ADL (β = 1·74; 95 % CI (0·95, 2·53); P < 0·001) and IADL (β = 0·93, 95 % CI (0·48, 1·38)) compared with food secure participants. However, baseline food security did not significantly alter the 5-year trajectory in ADL (P-interaction between baseline food security and time for ADL and IADL = 0·41 and 0·47, respectively).

In this cohort of Boston area Puerto Rican adults, those who are food insecure had consistently higher ADL and IADL scores over time, compared with those who are food secure. Baseline food security did not appear to alter the trajectory in ADL or IADL score.

In mental health research, functional recovery is increasingly valued as an important outcome in addition to symptomatic remission.

Course types of functional limitations among depressed older patients and its relation with symptomatic remission were explored in a naturalistic cohort study (Netherlands Study of Depression in Older persons). 378 depressed older patients (≥60 years) and 132 non-depressed persons were included. Depressive disorders were assessed with Composite International Diagnostic Interview at baseline and two-year follow-up. Functional limitations were assessed every 6 months with the World Health Organization Disability Assessment II.

Depressed patients had more functional limitations compared to their non-depressed counterparts. Growth Mixture Modeling among depressed patients identified two trajectories of functional limitations, both starting at a high disability level. The largest subgroup (81.2%) was characterized by a course of high disability levels over time. The smaller subgroup (18.8%) had an improving course (functional recovery). After two years, the main predictor of functional recovery was the remission of depression. Among symptomatic remitted patients, female sex, higher level of education, higher gait speed, and less severe depression were associated with no functional recovery. Non-remitted patients without functional recovery were characterized by the presence of more chronic somatic diseases, a lower sense of mastery, and a higher level of anxiety.

1 in 5 depressed older patients have a course with functional recovery. Combining functional and symptomatic recovery points to a subgroup of older patients that might profit from more rigorous psychiatric treatment targeted at psychiatric comorbidity and a group of frail depressed older patients that might profit from integrated geriatric rehabilitation.

To examine the role of meaningful relationship characteristics, defined here as social network type, in relation to the association between functional impairment and depressive symptoms.

The sample included respondents aged 65 years and older (n = 26,401) from the fourth wave of the Survey of Health, Ageing and Retirement in Europe (SHARE). Respondents were classified into one of seven relationship network types (Distal Children (living at a distance), Proximal Family (living nearby), Spouse, Other Family, Friend, Other, and No Network) according to the predominant characteristics of their most meaningful relationships. A two-stage regression analysis was performed in which the number of depressive symptoms was first regressed on the extent of functional impairment and network type, controlling for sociodemographic characteristics, cognition, health, and country. In the second stage, variables representing the interactions between functional impairment and network type were considered.

The compositional characteristics of respondents’ relationships in later life, as defined by social network type, were associated with depressive symptoms. In particular, when experiencing functional impairment, those without any meaningful relationships were found to have more depressive symptoms when compared to all other network types. The findings underscore the importance of meaningful relationships for the mental health of older adults experiencing functional impairment as well as the risk of experiencing depression among those who maintain no personal social network.

The study shows that differing constellations of meaningful relationships in later life yield different associations with mental health, especially when taking functional limitations into account.
