Life satisfaction, loneliness, and mental health in older adults: sociodemographic influences in a cross-sectional analysis.
Article in BMC geriatrics, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundLoneliness is a multidimensional experience that becomes particularly salient in older adulthood and is closely linked to depression and anxiety. Life satisfaction represents the cognitive component of subjective well‑being and may buffer against psychological distress. Sociodemographic factors such as sex, marital status, cohabitation, and rural or urban background may shape these experiences, yet their combined influence remains insufficiently understood. This study examined how different forms of loneliness and life satisfaction relate to mental health in older adults, and how sociodemographic characteristics contribute to these associations.
methodsA cross‑sectional study was conducted with 143 community‑dwelling older adults aged 65 to 84 years living in urban and rural areas of La Rioja, Spain. Participants completed validated measures of life satisfaction; social, romantic, and family loneliness; depression; and anxiety. Logistic and linear regression models were used to identify predictors of depression and anxiety, and of life satisfaction and loneliness, respectively. When model assumptions were not met, correlation analyses were applied instead.
resultsSocial loneliness (p<0.001) and female sex (p=0.002) were significant risk factors for both depression and anxiety, whereas being 75 years or older (p=0.018) and higher life satisfaction (p<0.001) protected against depression. Romantic and social loneliness were strongly associated with lower life satisfaction (both p<0.001). Social loneliness increased among participants who cohabited (p=0.004), were socially isolated (p<0.001), and reported higher family loneliness (p<0.001), while life satisfaction acted as a protective factor (p<0.001). Romantic loneliness was lower among married participants (p<0.001), those raised in rural environments (p=0.003), and those reporting higher life satisfaction (p<0.001). Family loneliness correlated positively with social and romantic loneliness and negatively with life satisfaction (all p<0.01). Cohabiting and being married did not exert equivalent effects, indicating distinct relational influences.
conclusionsLife satisfaction and loneliness are key determinants of mental health in older adults, with sociodemographic factors shaping their expression. Social loneliness plays a central role in depression and anxiety, while marriage and rural upbringing protect against romantic loneliness. Interventions that enhance life satisfaction and address specific forms of loneliness may support psychological well‑being in later life.
