Although it is widely believed that emotions vary with age, there is a dearth of information on emotional experiences in later adulthood. Several researchers think that older adults experience less emotional intensity than younger people while others have suggested that aging is accompanied by a decrease in positive affect and an increase in negative emotions. Sex similarities and differences in emotionality have also been documented. This study focuses on age and sex similarities and differences in emotional control. Three hundred and twenty seven men and women aged 19 to 92 years were administered two emotion measures. The results support previous research which suggests that the control of emotions increases with age. In evaluating sex differences in emotional control, women scored as more emotionally expressive than men, a finding which is consistent with previous research. Results are discussed in relation to socioemotional selectivity theory.

AbstractPast research has been inconsistent with regard to the effects of normal aging and sex on strategy use during verbal fluency performance. In the present study, both Troyer et al.’s (1997) and Abwender et al.’s (2001) scoring methods were used to measure switching and clustering strategies in 60 young and 72 older adults, equated on verbal ability. Young adults produced more words overall and switched more often during both phonemic and semantic fluency tasks, but performed similarly to older adults on measures of clustering. Although there were no sex differences in total words produced on either fluency task, males produced larger clusters on both tasks, and females switched more frequently than males on the semantic but not on the phonemic fluency task. Although clustering strategies appear to be relatively age-insensitive, age-related changes in switching strategies resulted in fewer overall words produced by older adults. This study provides evidence of age and sex differences in strategy use during verbal fluency tests, and illustrates the utility of combining Troyer’s and Abwender’s scoring procedures with in-depth categorization of clustering to understand interactions between age and sex during semantic fluency tasks.

Abstract Background Cerebral autoregulation (CAR) systems maintain blood flow to the brain across a wide range of blood pressures. Deficits in CAR have been linked to gait speed but previous studies had small sample sizes and used specialised equipment which impede clinical translation. The purpose of this work was to assess the association between gait speed and orthostatic cerebral oxygenation in a large, community-dwelling sample of older adults. Methods Data for this study came from the Irish Longitudinal Study on Ageing. A near infrared spectroscopy (NIRS) device attached to the forehead of each participant (n=2708) was used to track tissue saturation index (TSI; the ratio of oxygenated to total haemoglobin) during standing. Gait speed (GS) was assessed using a portable walkway. Results Recovery was impaired in slower GS participants with a TSI value at 20 seconds (after standing) of -0.55% (95% CI: -0.67, -0.42) below baseline in the slowest GS quartile versus -0.14% (95% CI: -0.25, -0.04) in the fastest quartile. Slower GS predicted a lower TSI throughout the 3-minute monitoring period. Results were not substantially altered by adjusting for orthostatic hypotension. Adjustment for clinical and demographic covariates attenuated the association between but differences remained between GS quartiles from 20 seconds to 3 minutes after standing. Conclusion This study reported evidence for impaired recovery of orthostatic cerebral oxygenation depending on gait speed in community-dwelling older adults. Future work assessing NIRS as a clinical tool for monitoring the relationship between gait speed and cerebral regulation is warranted.

Abstract Background There are few epidemiological evidences of sex differences in the association between dynapenic abdominal obesity and the decline in physical performance among older adults. Objectives To investigate whether the decline in physical performance is worse in individuals with dynapenic abdominal obesity and whether there are sexes differences in this association. Methods A longitudinal analysis was conducted with 3,881 participants of the English Longitudinal Study of Ageing aged 60 years or older in an eight-year follow-up period. The outcome was physical performance evaluated using the Short Physical Performance Battery (SPPB). Abdominal obesity was determined based on waist circumference (> 102 cm for men and > 88 cm for women). Dynapenia was determined based on grip strength (< 26 kg for men < 16 kg for women). The sample was divided into four different groups: non-dynapenic/non-abdominal obese (ND/NAO); non-dynapenic/abdominal obese (ND/AO); dynapenic/non-abdominal obese (D/NAO); and dynapenic/abdominal obese (D/AO). Changes in SPPB performance levels in these groups, stratified by sex, were analyzed using generalized linear mixed models adjusted by sociodemographic, behavioral and clinical characteristics. Results At baseline, women with D/AO had the worst performance on the SPPB among the groups analyzed (-1.557 points; 95% CI: -1.915 to -1.199; p < 0.001), and men with D/AO had a worse performance on the SPPB compared to those in the ND/NAO and ND/AO groups (-1.179 points; 95% CI: -1.639 to -0.717; p < 0.001). Over the eight-year follow-up, men with D/AO had a faster decline in performance on the SPPB compared to those in the ND/NAO group (-0.106 points per year; 95% CI: -0.208 to -0.004; p < 0.05). Conclusion Dynapenic abdominal obesity accelerates the decline in physical performance in men but not women.

Abstract Aging is associated with reduced slow wave (SW) density (number SW/min in nonrapid-eye movement sleep) and amplitude. It has been proposed that an age-related decrease in SW density may be due to a reduction in electroencephalogram (EEG) amplitude instead of a decline in the capacity to generate SW. Here, we propose a data-driven approach to adapt SW amplitude criteria to age and sex. We predicted that the adapted criteria would reduce age and sex differences in SW density and SW characteristics but would not abolish them. A total of 284 healthy younger and older adults participated in one night of sleep EEG recording. We defined age- and sex-adapted SW criteria in a first cohort of younger (n = 97) and older (n = 110) individuals using a signal-to-noise ratio approach. We then used these age- and sex-specific criteria in an independent second cohort (n = 77, 38 younger and 39 older adults) to evaluate age and sex differences on SW density and SW characteristics. After adapting SW amplitude criteria, we showed maintenance of an age-related difference for SW density whereas the sex-related difference vanished. Indeed, older adults produced less SW compared with younger adults. Specifically, the adapted SW amplitude criteria increased the probability of occurrence of low amplitude SW (&lt;80 µV) for older men especially. Our results thereby confirm an age-related decline in SW generation rather than an artifact in the detection amplitude criteria. As for the SW characteristics, the age- and sex-adapted criteria display reproducible effects across the two independent cohorts suggesting a more reliable inventory of the SW.
