The effects of gender, age, and body mass index on standing lumbar curvature in persons without current low back pain
Abstract
Reference values for standing lumbar curvature (SLC) obtained via noninvasive methods are not well established in persons without current low back pain. The effect of gender is considered to have a significant effect on SLC with women having more lumbar lordosis than men. The effect of age and degree of obesity are not considered to have a statistically significant effect on SLC. The purpose of this study was to test the assumption that measurements of SLC in healthy adults obtained by a flexible curve will differ between genders, whereas the SLC will not differ across categories of age and body mass index (BMI). Two hundred thirty-five volunteers (119 men and 116 women) whose ages ranged between 20 and 79 years participated in the study. Subjects were almost exclusively White and from the Midwest. Measurements of the SLC were obtained by a flexible curve. The curve's shape was transferred to poster board, and the value of SLC was quantified by a previously described technique. A three-way analysis of variance (alpha = 0.05) was used to examine the main effects of gender, age, and BMI on SLC. The effect of gender (F1,199 = 21.4, p < 0.0001) and the effect of age (F5,199 = 2.8, p < 0.017) were statistically significant. The effect of BMI (F2,199 = 1.8, p = 0.176) was not significant. Women (mean, 49.5 degrees +/-10.7 degrees ) demonstrated about 6.5 degrees more SLC than their male (mean, 43.0 degrees +/-10.7 degrees ) counterparts. For age, the only significant difference was…

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.
