Dizziness and imbalance and their association with general and mental health in a community-based cross-sectional study of middle-aged individuals: the Busselton healthy ageing study.

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
backgroundDizziness and imbalance are common symptoms among patients visiting healthcare providers. Current knowledge about their prevalence, impact on daily life, and associated factors is primarily based on selected samples from individuals seeking medical help, particularly older individuals. This study aimed to estimate the prevalence, symptoms, and impact of dizziness or imbalance symptoms, and to assess the association between these symptoms and their characteristics with demographic, general health, and mental health factors in middle-aged men and women from a representative, general population sample.
methodsCross-sectional data were collected from participants aged 45 to 70 years in the Busselton Healthy Ageing Study (BHAS), recruited in the City of Busselton, Western Australia. The data included physical tests and health-related questionnaires covering demographics, medical history, general and mental health, including any dizziness and imbalance symptoms and their impact on daily life. Estimates were made of the prevalence, patterns, and impact of dizziness and imbalance symptoms. Logistic regression was employed to calculate the association between demographic, mental and general health (independent variables) and the presence of dizziness or imbalance symptoms (dependent variable). Adjustments were made for sex and age as confounding factors.
resultsOf the 5086 participants, 1216 (23.9%) reported imbalance or dizziness, with light-headedness the most common type (64.3%; 782 of 1216). For nearly half (565; 46.5%) the imbalance or dizziness occasionally effected daily life, while for some, the impact was frequent (n = 50, 4.1%) or constant (n = 15, 1.2%). Being female (adjusted OR 2.05, 95%CI 1.79-2.34) and older in age (in years; adjusted OR 1.02, 95%CI 1.00-1.03), having a history of general health issues, and experiencing mental health problems or mental health symptoms were significantly associated with dizziness or imbalance symptoms.
conclusionsDizziness or imbalance are common symptoms among individuals aged 45 to 70 years and are associated with older age, being female, and poorer general and mental health. Given that approximately half of those affected reported occasional effects on daily life, with a few reporting frequent or constant effects, the outcomes of the study could help to raise awareness among healthcare providers about the prevalence, symptoms, and associated conditions.
