To quantify the association between multiple intentional weight losses (i.e., weight fluctuations) and the development of hypertension and diabetes mellitus among 50,790 female nurses participating in the ongoing Nurses' Health Study II. In addition to assessing the consequences of weight fluctuations, their correlates and course were identified.
In the United States, approximately one third of adult women are trying to lose weight. Most weight losses are not sustained and in fact may be followed by gains of at least as much weight as was intentionally lost. It is unclear whether there are adverse outcomes associated with multiple intentional weight losses.
The prospective study addressed the impact of weight fluctuation on development of hypertension (HPT) and diabetes (DM) by following women who significantly fluctuated in weight compared to those who generally maintained a stable weight. The subject source was all participants between 1989 and 1993 in the Nurses Health Study II (NHS) who did not experience a full term pregnancy between 1989 and 1993 and who were free of HPT, DM and cancer in 1993. A random sample of each of two weight fluctuation classifications, >20 lbs. (3 or more times) and 10-19 lbs. (3 or more times) was identified. A control group of non-fluctuators was matched by age and body mass index strata. Baseline data consisted of information obtained from the 1993 NHS II follow-up along with supplemental questionnaires sent to study participants to elicit specific information on past and present weight gain/loss and intentionality of weight fluctuation. Prospective data came from follow-up questionnaires in 1995, 1997, and 1999. Hypertension and DM ascertainment were obtained from self-report in the questionnaire. This ascertainment method appeared quite adequate based on validity studies carried out on subsamples of this cohort.

Diseases of long duration and generally slow progression. The four main types of noncommunicable diseases are CARDIOVASCULAR DISEASES (e.g., heart attacks and stroke), CANCER, chronic respiratory diseases (e.g., CHRONIC OBSTRUCTIVE PULMONARY DISEASE and ASTHMA) and DIABETES MELLITUS.
Unexpected rapid natural death due to cardiovascular collapse within one hour of initial symptoms. It is usually caused by the worsening of existing heart diseases. The sudden onset of symptoms, such as CHEST PAIN and CARDIAC ARRHYTHMIAS, particularly VENTRICULAR TACHYCARDIA, can lead to the loss of consciousness and cardiac arrest followed by biological death.
