Check your height to weight ratio using the approximate height to weight chart guide below. Now in both Metric and Imperial measurements; Inches/Centimeters . Nov 1, Previous studies have reported an inverse association between height and risk of cardiovascular disease. However, evidence is limited for the. Oct 17, Background. Body mass index (BMI) tends to be higher among shorter adults, especially women. The dependence of BMI–height correlation on.
Weight is measured to the nearest g using electronic scales after removal of shoes or bulky clothing participants were not weighed if they were pregnant, unsteady on their feet or chair-bound. Height, to the nearest millimetre, was measured using a portable stadiometer.
We included only individuals where both a valid height and weight measurement were recorded.
Those who were considered by the interviewer to have unreliable measurements were excluded from the analysis. We extracted the core variables of person identifier, year, age and validated with height and weight BMI, together with smoking status and equivalized household income for sensitivity analysis. Statistical analyses The relationship between height group by quartile and BMI was first explored graphically by gender and calendar time; simple regressions were used to assess the dependence of BMI on height, stratified by gender.
An F test was used to test for an interaction between height quartile and gender in a regression model with BMI as the outcome and height quartile, gender, and their interaction as predictors.
We then used a more complex regression model to investigate interactions and non-linear effects, in which log weight was taken as the response and regressed on log height as a continuous variable.
We fitted separate models for males and females; we corrected for age and calendar time and allowed interactions between them. The variable log height was constrained to be linear, but age and calendar time were allowed to have non-linear effects. The key output was the log height coefficient—the Benn Index—which can vary according to the other covariates through its interactions.
The model fitting procedure was as follows. These effects did not vary according to age, education, alcohol and tobacco consumption, or with use of hormonal therapies.
In middle-aged women, the risk of having a hip or knee replacement increases with both increasing height and increasing BMI. From a clinical perspective, relatively small increases in average BMI among middle-aged women are likely to have a substantial impact on the already increasing rates of joint replacement in the UK. Joint replacementObesityAnthropometryProspective studyMillion Women Study Rates of primary hip and knee joint replacement are rising in many developed countries and with the ageing of the population they are likely to continue to increase [ 1 ].
The main indication for both operations is severe osteoarthritis of the respective joint although rheumatoid arthritis, trauma and avascular necrosis account for a small percentage of replacements [ 2—4 ]. Many studies have examined risk factors for osteoarthritis of the hip and knee with case definitions depending upon radiological or clinical signs. Joint replacement is, however, a well-defined and clinically important endpoint with a significant cost to health systems [ 5 ], yet few studies have examined risk factors for this.
In England, hip and knee replacement rates are higher in women compared with men, and rise steeply after the age of 60 yrs [ 1 ].

Increasing body mass index BMI has consistently been associated with an increased risk of knee osteoarthritis [ 6—8 ] while the evidence has been less consistent for the relationship between BMI and hip osteoarthritis [ 8—10 ]. With respect to joint replacement, two prospective cohort studies have shown that BMI predicts total hip replacement for osteoarthritis [ 1112 ] and one study also found a relationship between adult height and hip replacement [ 13 ].
A case-control study found increasing BMI was associated with being on a waiting list for knee replacement, but we know of no studies that have looked at height and knee replacement.
This is despite the fact that adult height correlates with joint dimensions and may reflect bone development [ 1415 ]. Therefore, we investigated the relationship between height, weight and BMI on the risk of primary hip and knee joint replacement in a prospective study of middle-aged women.

Subjects and methods Study population The Million Women Study is a population-based prospective cohort study that recruited 1. The study aims, methods and the characteristics of the study population have been described elsewhere [ 16 ].Perfect Height And Weight Chart For Men And Woman.
Briefly, women were recruited through attendance at breast-screening clinics and were asked to complete a baseline questionnaire, which included questions on socio-demographic, lifestyle and anthropometric factors and medical history. In —, women who entered the study were sent a follow-up questionnaire to update exposure information and ascertain certain incident morbidity.
On the return of the questionnaire, if the respondents had written down an operation, this was manually coded by clinical coders and entered into the study database. Revision joint replacements were coded separately. We presumed that the accuracy of self-reporting would be similar between participants recruited in England and Scotland.
Participants who had returned a follow-up questionnaire and had their responses entered into a database by 31 December were eligible to be included in these analyses. All the participants provided written consent to be included in the study and the study protocol has been approved by the English National Health Service Eastern Multi-Centre Research Ethics Committee.
