Association between Subjective Sleep Quality, Hypertension, Depression and Body Mass Index in a Nigerian Family Practice Setting
Open accessAbstract
Objectives: Poor subjective sleep quality in primary care has not been widely studied in Nigeria; hence this study was aimed to evaluate the subjective sleep quality and to find the association with blood pressure, depression and body mass index. Methodology: Pittsburg Sleep Quality Index (PSQI) questionnaire was administered. Good sleep quality was defined as PSQI less than 5. The level of depression was assessed using the Patient Health Questionnaires (PHQ– 9). Results: The sample consisted of 400 subjects in the age group 18-70years. The overall mean age did 48.0 + 13.2 years, with the age group 41-50years constitute 29.5% of the studied subjects. Whilst 240 (60%) had normal blood pressure, 29(7.5%) had stage 1 and 43 (10.8%) had stage 2 hypertension. One hundred and thirty eight (34.5%) had normal weight, while 108 (27.0%) were obese. Overall sleep quality was very good, fairly good, fairly bad, and very bad in, 30.8%, 33.2%, 19.5%, and 16.5% of the respondents respectively. The prevalence of poor sleep quality was 44.0%. There was strong statistical association between poor sleep quality, blood pressure (p-value 0.002), depression (p-value 0.000) and body mass index (p-value 0.05). Conclusion: A substantial proportion of the subjects had poor sleep quality associated with high blood pressure, increased body mass index and depression.

Prior cross-sectional studies have identified an association between smoking and poor sleep quality.
“The previously conducted cross-sectional studies have identified that there is association between sex, residence, and substance use [31] (such as alcohol [32], khat [33–37], smoking [38, 39], caffeinated beverages [35, 40], and other stimulants) in different countries with poor sleep quality.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
