Gender differences in associations of eating pathology between mothers and their adolescent offspring.

OBJECTIVE: To study the association of eating pathology between mothers and their adolescent offspring in a population sample. RESEARCH METHODS AND PROCEDURES: The participants were 481 women (mean age, 47+/-SD 5 years; BMI, 25+/-4 kg/m2) and their 481 adolescent children 16 to 17 years old (BMI, 21+/-3 kg/m2) of the Stockholm Weight Development Study. Assessment methods were the Three-Factor Eating Questionnaire Revised 18 and the Eating Disorder Inventory 2. RESULTS: A higher body weight was most related to cognitive restraint for adolescents and to emotional eating for adult women. A mother-daughter link could be identified for eating pathology, with the strongest link found for emotional eating. No mother-son link could be identified. Age subgroup analyses revealed a stronger mother-daughter link for body attitudes in younger mothers and for cognitive restraint in older mothers. DISCUSSION: Gender differences revealed that eating pathology was shared by mothers and daughters but not by mothers and sons. A psychological strategy such as eating as a response to negative emotions was most interrelated between mothers and daughters. Younger mothers shared more attitudes toward the body with their daughters, whereas older mothers shared more restrictive eating behaviors with their daughters. The mother-daughter links found may be due to gender-specific genetic and psychological family transmission and gender-specific environmental influences. The sons' eating behaviors seem to be more independent and would be formed by other factors than for the girls.

Long-term weight development in women: a 15-year follow-up of the effects of pregnancy.

OBJECTIVE: The aim of this study was to evaluate how well prepregnancy BMI, gestational weight gain, and postpartum weight retention predict retention of weight 15 years later among parous women. RESEARCH METHODS AND PROCEDURES: The Stockholm Pregnancy and Women's Nutrition (SPAWN) study is a long-term follow-up study of women who delivered children in 1984 to 1985 (n = 2342). The participants initially filled out questionnaires about their eating and exercise habits, social circumstances, etc. before, during, and at 1 year after pregnancy. Anthropometric data were also sampled. Fifteen years later, these women were invited to take part in the follow-up study. Anthropometric measurements were collected, and similar questions were asked. Five hundred sixty-three women participated in the SPAWN 15-year follow-up study. The sample was divided into groups to examine three presumably critical time periods: 1) overweight and normal weight before pregnancy; 2) low, intermediate, and high weight gainers during pregnancy; and 3) low, intermediate, and high weight retainers at 1 year after pregnancy. RESULTS: The overweight women did not gain more weight during pregnancy or retain more weight at 1 year follow-up. High weight gainers during pregnancy retained more weight at the 1-year and the 15-year follow-ups. High weight retainers had gained more during pregnancy and retained it at the 15-year follow-up. Fifty-six percent of the high weight gainers during pregnancy ended up in the high weight retainers group. DISCUSSION: Women who are overweight before pregnancy do not have a higher risk of postpartum weight retention than normal weight women. Thus, it is not necessarily the initially overweight woman who should be the target or focus of weight control programs during or after pregnancy. Both high weight gainers and high weight retainers had higher BMI at the 15-year follow-up, although only 56% of the high weight gainers during pregnancy were also classified as high weight retainers at the 1-year follow-up. Weight retention at the end of the postpartum year predicts future overweight 15 years later.

[Easy to remain overweight after pregnancy].

For some women pregnancy is a trigger factor for developing overweight and obesity. 73% of patients at the Obesity Unit, Huddinge University Hospital, indicated that they had retained more than 10 kg after each of their pregnancies; for this subgroup weight development after pregnancy was of obvious importance for their future health. However, in most studies mean weight retention after pregnancy is modest: 0.5-3.5 kg up to one year after delivery. Numerous studies have analysed factors explaining weight development after pregnancy and delivery, with a wide range of subjects, but overall it has been surprisingly difficult to identify strong predictors for weight development. The strongest factor is weight gain during pregnancy, but smoking cessation, a sedentary lifestyle and socio-economic factors also play a role. Pregnancy and weight development are intertwined in a complex pattern, which includes a change in lifestyle factors, such as eating behaviour, physical activity, smoking cessation and degree of lactation, but which are still not fully understood.

Vision and eating behavior in obese subjects.

OBJECTIVE: Vision is one of a number of factors influencing the amount of food consumed during a meal. The purpose of this study was to investigate the impact of vision on the microstructure of the eating behavior of obese subjects. RESEARCH METHODS AND PROCEDURES: Eighteen obese subjects with a body mass index (mean +/- SD) of 39.1 +/- 6.3 kg/m(2) twice consumed a standardized test meal in excess, once with and once without a blindfold. The microstructure of the eating behavior was registered by VIKTOR, a computerized eating monitor. Subjective motivation to eat (i.e., desire to eat, hunger, satiety, and prospective consumption) was rated by visual analogue scales (VASs) before, immediately after, and then hourly up to 3 hours after the test meals. RESULTS: The obese subjects ate 24% less food when blindfolded (359 +/- 194 g vs. 472 +/- 179 g; p < 0.01). Despite a smaller amount of food consumed when blindfolded, there were no significant differences with or without the blindfold for any of the VASs measuring subjective motivation to eat after test meals. DISCUSSION: The importance of vision in regulating our eating behavior was demonstrated in this study. The obese subjects ate 24% less food blindfolded without feeling less full. Eating blindfolded could be tested as a didactic tool to make obese subjects aware of what factors affect the termination of eating.

Interrelationships between weight development and weight retention in subsequent pregnancies: the SPAWN study.

BACKGROUND: Pregnancy is frequently associated with post-delivery weight retention in women. Most studies suggest weight retention associated with pregnancy of between 0.5 to 3.8 kg with up to 2.5 years of follow-up. However, 73% of the female patients at our obesity clinic report that their pregnancies have been important trigger factors for marked weight gain and that they had gained more than 10 kg after each pregnancy. The aim of this study was to examine correlations in weight gain and weight retention after pregnancy in the long-term perspective. METHOD AND SUBJECTS: The SPAWN (Stockholm Pregnancy and Women's Nutrition) study is a long-term follow-up study of women who delivered children in 1984-85 in Stockholm (n = 2342). The participants filled out questionnaires about their eating and exercise habits, social condition, etc. before, during and up to 1 year after pregnancy. Antropometric data were also sampled. One thousand four hundred and twenty-three women completed the study and filled out all questionnaires up to 1 year after pregnancy. Fifteen years later, these 1423 women were invited to the follow-up study. Five hundred and sixty-three women participated and filled out extended questionnaires, and antropometric data were also sampled. Data from the Swedish Medical Birth Register (MBR) about weight before and weight gain during pregnancy were collected. The sample was divided into groups regarding four critical time periods: (1) Time interval between first and second pregnancy, less and more than 2 years. (2) Overweight and normal weights before first pregnancy based on initial body mass index (BMI). (3) Low and high weight gainers during pregnancy by mean split. (4) Low and high weight retainers at 1 year after first pregnancy by mean split. RESULTS: 1) There were no differences between those women who have more than 2 years between their pregnancies regarding weight gain during and weight retention after the first and second pregnancy. (2) Overweight women did not gain more weight during pregnancy or retain more weight at 1 year of follow-up after the first and second pregnancy. (3) High weight gainers retained more weight at 1 year after both the first and second pregnancy. (4) High weight retainers had gained more during pregnancy and retained it into the second pregnancy, and also gained more during and retained more after the second pregnancy. DISCUSSION: To our knowledge, the SPAWN study is the longest follow-up study of factors affecting weight development after pregnancy. Women overweight before pregnancy did not have any higher risks of postpartum weight retention than normal weight women. Weight gain during pregnancy and weight retention up to 1 year after delivery is of predictive value for the weight development in the second pregnancy. Obviously the environmental variation is an important determinant of the differences in weight increase, which follow a pregnancy. Pregnancies time interval does not seem to be of any importance. There are practical implications of these findings: Women who plan their later pregnancy several years after the first pregnancy have no reason to assume that the weight development during subsequent pregnancies will be worse than before. On the other hand, women who have increased considerably in weight during the first pregnancy or retained weight after delivery have a higher risk of doing so in the subsequent pregnancies and should receive appropriate advise and support.

Natural course of gestational diabetes mellitus: long term follow up of women in the SPAWN study.

OBJECTIVES: Long term follow up women with gestational diabetes mellitus (GDM). DESIGN: Case-control study. SETTING: Academic obesity unit. POPULATION: Women earlier identified as having gestational diabetes mellitus. METHOD: Twenty-eight women diagnosed with GDM in 1984-1985, and a control group (n = 52) who gave birth at the same time performed a 2-h oral glucose tolerance test 15 years later. Basic anthropometry and questions about various aspects of eating and exercise habits were furthermore obtained. RESULTS: Ten women (35%) in the GDM group were diagnosed with type 2 diabetes mellitus and none in the control group (P < 0.001). Mean BMI in the diabetic group was 27.4 kg/m2 and in the non-diabetic GDM group 24.6 kg/m2 (P < 0.05). The mean weight gain since the first child was 8A kg in all GDM versus 8.1 kg in controls (ns). The women who developed type 2 diabetes mellitus, however, gained 15.1 kg since the birth of their first child (P < 0.05). CONCLUSIONS: Women who are diagnosed with GDM have a considerably higher risk of developing type 2 diabetes mellitus later in life. Despite a close medical monitoring during pregnancy, the further follow up within the health care system and information about long term consequences of GDM for later type 2 diabetes mellitus development seems to be generally lacking. More active strategies for future weight control and lifestyle advice after delivery might therefore be indicated for women with GDM.

Vision and eating behavior.

OBJECTIVE: Eating behavior is influenced by internal and external factors. Vision is one part of the complex pattern of factors influencing the amount of food consumed during a meal. The aim of this study was to explore the impact of vision on the microstructure of eating behavior and the subjective motivation to eat. RESEARCH METHODS AND PROCEDURES: Nine blind subjects and nine matched seeing control subjects consumed a standardized meal registered by VIKTOR, an eating monitor, measuring the microstructure of the eating behavior. The eating behavior of the control subjects was registered twice, with and without blindfold. RESULTS: The eating behavior of the blind subjects did not differ from that of seeing control subjects. However, the eating behavior of seeing subjects eating with blindfold demonstrated a clear impact of vision on eating behavior. When blindfolded, subjects ate 22% less food (p < 0.05), had shorter meal durations (p < 0.05), and had less decelerated eating curves (p < 0.05). Despite a smaller amount of food consumed when blindfolded, the reported feeling of fullness was identical to that reported after the larger meal consumed without blindfold. DISCUSSION: The importance of vision in regulating our eating behavior is further stressed in this study. Eating with a blindfold decreased the intake of food, without making subjects feel less full. Eating blindfolded, therefore, may force subjects to rely more on internal signals. These results might be used as an aid in the development of new treatment strategies for obese subjects.

Pharmacotherapy of obesity.

Whereas several drugs to treat most other chronic conditions have been developed over the last 30 years, progress in pharmacologic therapy for obesity has been slow. The record of drug treatment for obesity partly explains this phenomenon and is of concern. Several compounds have been withdrawn when severe side effects have been discovered. The lack of scientifically developed safe and effective antiobesity drugs has opened the gates for an enormous number of commercial products that make vast sums of money, but have no scientific evidence backing their efficacy. This pattern is seen in both developed and developing countries. summarizes some of the presently accepted, scientifically evaluated antiobesity drugs. At present, orlistat and sibutramine are the only two major drugs used almost worldwide.
