Purpose: To investigate the longitudinal associations between pain and depressive symptoms in adults. Methods: Prospective cohort study on data from 28,515 community-dwelling adults ≥ 50 years, free from depression at baseline (Wave 5), with follow-up in Wave 6 of the Survey of Health, Ageing and Retirement in Europe (SHARE). Significant depressive symptoms were defined by a EURO-D score ≥ 4. The longitudinal association between baseline pain intensity and significant depressive symptoms at follow-up was analysed using logistic regression models; odds ratios (ORs) and confidence intervals (CI) were calculated, adjusting for socio-demographic and clinical factors, physical inactivity, loneliness, mobility and functional impairments. Results: Mean age was 65.4 years (standard deviation 9.0, range 50–99); 14,360 (50.4%) participants were women. Mean follow-up was 23.4 (standard deviation 3.4) months. At baseline, 2803 (9.8%) participants reported mild pain, 5253 (18.4%) moderate pain and 1431 (5.0%) severe pain. At follow-up, 3868 (13.6%) participants—1451 (10.3%) men and 2417 (16.8%) women—reported significant depressive symptoms. After adjustment, mild, moderate and severe baseline pain, versus no pain, were associated with an increased likelihood of significant depressive symptoms at follow-up: ORs (95% CI) were 1.20 (1.06–1.35), 1.32 (1.20–1.46) and 1.39 (1.19–1.63), respectively. These associations were more pronounced in men compared to women, and consistent in participants aged 50–64 years, those without mobility or functional impairment, and those without loneliness at baseline. Conclusion: Higher baseline pain intensity was longitudinally associated with a greater risk of significant depressive symptoms at 2-year follow-up, in community-dwelling adults without baseline depression.

OBJECTIVE: Higher blood pressure variability (BPV), independent of mean blood pressure (BP), has been associated with adverse health outcomes. We investigated the association between visit-to-visit BPV and functional decline in older adults at high cardiovascular risk.METHODS: In PROspective Study of Pravastatin in the Elderly at Risk, 4745 participants with mean age of 75.2 years and high cardiovascular risk were followed for a mean of 3.2 years. BP was measured in every 3 months during the first 18 months. BPV was defined as the intraindividual SD of measurements across these visits. Functional status in basic and instrumental activities of daily living was measured using the Barthel (ADL) and Lawton (IADL) scales, first at 18 months and then during follow-up until 48 months. Functional decline was calculated over this period.RESULTS: BPV was not cross-sectionally associated with functional status at 18 months. Higher SBPV was associated with steeper functional decline, whereas DBPV was not. Each 10 mmHg higher SBPV was associated with a 0.064 (95% confidence interval 0.016-0.112, P = 0.009) annual decline in ADL score and with a 0.078 decline (95% confidence interval 0.020-0.136, P = 0.008) in IADL score. These associations were not modified by sex, hypertension or antihypertensives. These findings were independent of mean BP, cardiovascular risk factors and morbidities and cognition.CONCLUSION: Higher visit-to-visit SBPV but not DBPV was associated with steeper functional decline in older adults at high cardiovascular risk. Higher SBPV is a novel risk factor for functional decline.

BACKGROUND: optimal blood pressure targets in older adults are controversial.OBJECTIVE: to investigate whether the relation of blood pressure with mortality in older adults varies by age, functional and cognitive status.DESIGN: longitudinal geriatric outpatient cohort.SETTING: Milan Geriatrics 75+ Cohort Study.SUBJECTS: one thousand five hundred and eighty-seven outpatients aged 75 years and over.METHODS: the relations of systolic (SBP) and diastolic blood pressure (DBP) with mortality risk were analysed using Cox proportional hazards models. Blood pressure, Mini-Mental State Examination (MMSE) and Basic Activities of Daily Living (ADL) were assessed at baseline. All analyses were adjusted for socio-demographic factors, co-morbidities and medications.RESULTS: one thousand and forty-six patients died during 10-year follow-up. The relationships of SBP and DBP with mortality risk were U-shaped; SBP of 165 mmHg and DBP of 85 mmHg were associated with the lowest mortality. Patients with SBP < 120 mmHg and patients with SBP 120-139 mmHg had 1.64-fold (95% confidence intervals, CI 1.21-2.23) and 1.32-fold (95% CI 1.10-1.60) higher mortality risk than patients with SBP 160-179 mmHg (P values 0.001 and 0.004, respectively). In patients with SBP below 180 mmHg, higher SBP was associated with lower mortality in patients with impaired ADL and MMSE but not in those with preserved ADL and/or MMSE (P for interaction 0.033). Age did not modify the correlation of SBP with mortality.CONCLUSIONS: the correlations of SBP and DBP with mortality were U-shaped. Higher SBP is related to lower mortality in subjects with impaired ADL and MMSE. ADL and MMSE may identify older subjects who benefit from higher blood pressure.

OBJECTIVES: To evaluate whether the relationship between blood pressure (BP) measures and cognitive function is different according to age and functional status in older outpatients.DESIGN: Cross-sectional.SETTING: Outpatient hospital-based Milan Geriatrics 75+ Cohort Study.PARTICIPANTS: Individuals aged 75 and older (N = 1,540).MEASUREMENTS: Blood pressure, Mini-Mental State Examination (MMSE), basic activities of daily living (ADLs), and instrumental activities of daily living (IADLs) were assessed. Associations between BP measures and MMSE score were first analyzed in the total population using linear regression models and were then further examined according to strata of age, ADLs, and IADLs. All analyses were adjusted for sociodemographic factors and presence of comorbidities.RESULTS: In the total population, higher systolic BP (SBP), diastolic BP (DBP), pulse pressure (PP), and mean arterial pressure (MAP) were all associated with higher MMSE score (all P < .05). Each 10-mmHg higher SBP and DBP was associated with a 0.26- and 0.55-point higher MMSE score, respectively. The associations between MMSE score and SBP, DBP, and MAP differed materially according to strata of age and functioning and were most pronounced in those aged 85 and older, with ADL impairments, and with IADL impairments.CONCLUSION: Higher BP is associated with better cognitive function in the oldest old and in those with impaired functional status.
