Study of DPP extended over 2 groups selected as following: It was prospective in every patient seen between July 1976 and May 1977 (systematic study: SS: 35 girls and 2 boys). It was retrospective in another group before selected for importance of DPP (no systematic study: NSS: 34 girls and 6 boys). DPP were distributed into Dalpha (fear of any weight recovery), Dbeta (obsessing repercussion of a real defect, amplified in its perception) and Dgamma (delirious and obsessing conviction of a physical anomaly). We researched correlations with the type of AN (fixity or recession to childhood), premorbid weight-height ratio, overweight of the same-sex parent, important problems towards sexuality (ASC = Absolute sexual conflict = An entirely caused by a sexual difficulty, or PSC = Partial Sexual Conflict = difficulty towards sexuality when insuffisant to explain AN, or no sexual conflict), attitude towards pregnancy in cases of big-belly DPP. Every DPP were DPP of localized or generalized obesity. Dalpha is constant and pathognomonic. In females of SS, 37% presented Dbeta and 5% Dgamma before AN, 25% Dbeta and 11% Dgamma during AN. Among the 8 boys of the 2 studies, 3 presented Dgamma before AN, and everyone expressed their obsessing fear of "ugly grease". In 20% girls and 50% boys, explained aim of loss of weight was to "wipe out" the anomally DPP emphasized. We did not find any correlation between generalized DPP and studied elements, particularly with sexual conflicts (22% of our cases). The more frequent localized DPP was "big-belly"-DPP, always associated with overweight of the same sex parent, but as for other localized DPP, without any correlation with sexual conflicts, problems towards the father, neither reject of pregnancy.

With improvements in life expectancy and as more and more people have access to modern medicine, non-communicable diseases are emerging as a health problem in both urban and rural communities in Myanmar. Of all non-communicable diseases, cardiovascular diseases (CVD) are known to be the major health problem. Since many studies that have been conducted in both developed and developing countries have shown a difference between rural and urban communities with regard to cardiovascular diseases, our study had the objective of finding out the prevalence of ischemic heart disease, hypertensive heart disease and rheumatic heart disease in a rural and urban community. The risk of obesity and smoking in the occurrence of CVD was also studied. A cross-sectional survey was conducted in three urban townships of Yangon City (Sanchaung, Latha and Pabedan) and one rural township of Hmawbi. The results showed that CVD were a health problem in both the urban and rural communities. Coronary heart disease was seen to be more prevalent in the urban townships than in the rural Hmawbi Township, but hypertension (HT) and rheumatic heart diseases (RHD) were more prevalent in the rural township of Hmawbi. Obesity which has been blamed as the major risk factor for CHD and HT in the developed countries was not found to be a risk factor in the study townships, but smoking was.

Norepinephrine (NE), acting through alpha 2-noradrenergic receptors in the hypothalamic paraventricular nucleus (PVN), has been implicated in the control of feeding behavior and body weight gain. To determine whether this hypothalamic receptor system is disturbed in genetically obese rats, the binding of radioligands to alpha 2-noradrenergic, as well as to alpha 1-noradrenergic, receptors was examined in seven hypothalamic nuclei of obese Zucker rats relative to their lean littermates. Receptor binding procedures, using the alpha 2-noradrenergic agonist [3H]p-aminoclonidine ([3H]PAC) and the alpha 1-noradrenergic antagonist [3H]prazosin, demonstrated that the obese rats, compared to the lean rats, had significantly greater alpha 2-noradrenergic and alpha 1-noradrenergic receptor binding, specifically in the PVN as opposed to other hypothalamic areas examined. Moreover, the obese rats, compared to the lean rats, exhibited greater responsiveness to the effects of food deprivation (48 h), which caused a significant decline in radioligand binding to both alpha 2 and alpha 1 receptors, specifically in the PVN. A decrease in alpha 2-receptor binding after deprivation in the obese rats was also seen in two basal hypothalamic areas, namely, the supraoptic nucleus and arcuate nucleus-median eminence. The possibility exists that these disturbances in hypothalamic alpha-receptors may be involved in the development and/or maintenance of the genetic obesity.

In Australia the most important preventable causes of cancer, in order of importance, are tobacco smoking, diet, obesity, sunlight exposure, alcohol consumption and occupational exposure to carcinogens. We review and discuss these causes and their potential preventability and discuss three broad strategies in cancer prevention: public health policy and legislation, screening, and education and behavior change. In each of these broad areas, current research evidence and relevant approaches to research and development are considered. Six areas of research and development priority for cancer prevention and education are suggested: cigarette smoking (particularly among children and adolescents); protection of the skin from exposure to strong sunlight; screening; dietary choices; occupational exposures; and the social and environmental context of cancer prevention. All of these strategies and concerns will not apply to every country in the Asia-Pacific region but may be useful as guidelines and as a stimulus for determining particular local priorities.

The displacement of sports and other physical activities by television and video may contribute to the associations among television viewing, obesity, and reduced physical fitness. Because video games are widely played by children and adolescents, we assessed the metabolic and cardiovascular responses to video game playing. Heart rate, blood pressure, and oxygen consumption were measured serially over 30 minutes in 32 males and females aged 16 to 25 years (mean +/- SEM, 20 +/- 1 years) while they played the "Ms Pac-Man" video game under standard laboratory conditions and compared with measurements made in a standing but inactive position. Playing the video game significantly increased heart rate, systolic and diastolic blood pressure, and oxygen consumption. Energy expenditure increased from 6.08 +/- 0.24 kJ/min while the subjects stood inactive to 10.94 +/- 0.49 kJ/min while they played. The increase in metabolic rate and cardiovascular stimulation was similar in magnitude to mild-intensity exercise.

Brain alpha-adrenoceptor (alpha-AR) binding was examined as a possible explanation for the persistence of diet-induced obesity (DIO) or resistance (DR) in rats after they were returned to chow from a high-energy, fat and sucrose diet (CM diet). Adult Sprague-Dawley rats (n = 28) were fed the CM diet for 12 weeks. Those that gained more weight than chow-fed controls were classified as DIO and those that gained the same weight as controls were called DR. The 10 heaviest DIO and 8 lightest DR rats were then placed on chow for an additional 14 weeks. After the entire 26-week period, the body weights of DIO rats were still 21 per cent greater and those of the DR rats were 9 per cent less than 7 chow-fed controls. DIO retroperitoneal fat pads were also 62 per cent heavier while DR pads were equal to controls. Plasma insulin and glucose levels were comparable in all 3 groups. Receptor autoradiographic studies of brain alpha 1-AR (3H prazosin; PRZ) and alpha 2-AR (3H-paraminoclonidine; PAC) adrenoceptor binding were carried out using these animals at the end of 26 weeks. Binding to alpha 1-AR was comparable in all groups but alpha 2-AR binding was 47-103 per cent higher in DIO compared to DR and chow-fed controls in 14 of 17 brain areas assessed. These included the dorsomedial, ventromedial and paraventricular hypothalamic n. and all amygdalar areas. Such widespread differences in alpha 2-AR binding in rats fed the same diet but of differing body weights suggest that alpha 2-AR binding is a marker for differences in body weight regulation and may be important in the control of the differences in weight gain.

Half the rats fed a high-energy diet develop diet-induced obesity (DIO); the remainder are diet-resistant (DR). Since alpha-adrenoceptors modulate both food intake and body weight, this study was conducted to identify potential differences in brain alpha-receptor binding which might predispose some animals to become DIO (DIO-prone) and others DR (DR-prone) when fed a high energy diet. DIO-prone rats can be prospectively identified by high and DR-prone rats by a low plasma norepinephrine (NE) response to i.v. glucose. Here 28 chow-fed rats were tested for glucose-induced NE release and the 6 highest and 6 lowest plasma NE responders were identified as being most likely to be DIO- and DR-prone, respectively. Binding to brain alpha-adrenoceptors was studied in these 12 rats by receptor autoradiography using 1 nM [3H]prazosin (PRZ; alpha 1-) and 1 nM [3H]paraminoclonidine (PAC; alpha 2-). There were no differences in [3H]PRZ binding in any of 18 brain areas examined. However, DIO-prone [3H]PAC binding was only 14-39% of DR-prone levels in 9 areas including 4 amygdalar nuclei, the lateral area, dorso- and ventromedial nuclei of the hypothalamus, median eminence and medial dorsal thalamic n. Although it is unclear whether this widespread decrease in [3H]PAC binding implicates brain alpha 2-adrenoceptors in the pathophysiology of DIO, it does correlate with a phenotypic marker (increase glucose-induced NE release) which predicts the subsequent development of DIO on a high-energy diet.

While many autonomic and metabolic defects associated with genetic obesity in the Zucker rat are corrected by adrenalectomy (Adx), brain adrenoceptor function has not been examined in this context. Here, 3 weeks after Adx or sham surgery, brains of 11 weeks old lean (Fa/Fa) and obese (fa/fa) male Zucker rats were assayed for alpha 1-([3H]prazosin; [3H]PRZ) and alpha 2-adrenoceptor ([3H]paraminoclonidine; [3H]PAC) binding by autoradiography. By genotype, obese rats had 19-256% higher [3H]PRZ binding than lean rats in the amygdala (central [ACN], basolateral [ABL], basomedial [ABM] and medial [MAN] nuclei [n.]), hypothalamus (dorsomedial n. [DMN] and lateral [LH]) and somatosensory cortex. In the ABL and ACN, increased maximal binding (Bmax) in obese rats was associated with decreased affinity (increased Kd). Three weeks after surgery, sham-operated obese rats gained 27% more weight than lean rats but lean and obese Adx rats gained the same amount of weight. Adx reduced [3H]PRZ binding in both lean and obese rats by 37-70% in the amygdala (ABM, ACN, MAN) compared to sham-operated rats. But, Adx selectively reduced [3H]PRZ binding only in lean rats in the ABL, DMN, ventromedial hypothalamic n. (VMN) and ventroposteromedial thalamic n. In most areas, decreases in maximal binding (Bmax) associated with Adx were accompanied by decreases in Kd. Unlike [3H]PRZ binding, there was no consistent genotype difference in [3H]PAC binding although Adx was followed by increased binding in obese and decreased binding in lean rats in the ABL. In only the VMN, obese rats had a 21% higher alpha 2- to alpha 1-adrenoceptor ratio than lean rats.(ABSTRACT TRUNCATED AT 250 WORDS)

The present study was conducted to assess the pattern of body mass index (BMI) prevalence of obesity, and the association between obesity and other health-related problems in a Saudi population. The study was conducted in Queza district of Jeddah, Saudi Arabia. A systematic random sample of Saudi nationals aged 16 years and above were selected (total number 1037; 611 males and 426 females). The study population was clinically examined and a specially-designed questionnaire was administered to obtain the information. Anthropometric measurements, blood pressure and urine analysis were carried out. The collected data were analyzed using simple as well as multivariate statistical methods. It was observed that BMI significantly increased with age. The crude mean BMI was significantly greater in females compared to males. Prevalence of Grade I obesity among different age groups in males ranged from 15.7% to 43.0%, while in females the range was from 22.8% to 45.7%. Similar patterns for both genders were found for Grade II obesity (5.2%-18.9%; and 11.1%-47.8% respectively). Obesity was significantly associated with an increase in both systolic and diastolic blood pressure, where increase in BMI by one unit increased systolic blood pressure by 0.617 mm Hg, and diastolic blood pressure by 0.484 mm Hg. This relationship held true even after allowing for other confounding factors. The present study concluded that obesity is a problem prevalent in the community of Queza district. It is recommended that health education programs be implemented through primary health care services in the community to prevent this problem.

Non-insulin-dependent diabetes mellitus (NIDDM), or type II diabetes is rapidly becoming one of the most common chronic disease in the United States and worldwide, with more than 7% of the adult population affected. NIDDM is even more common in the elderly and in minority population including Hispanic Americans, African Americans, Asian and Pacific Island Americans, and Native Americans. In these populations, NIDDM may be present in 10% to as much as 50% of the adult population. However diagnosed NIDDM is only the tip of the iceberg of an epidemic of glucose intolerance. Impaired glucose intolerance (IGT) is even more prevalent that NIDDM; and in addition to be a major risk factor for the development of NIDDM, IGT is associated with an increased risk of macrovascular disease. Recent advances in research into the etiology and natural history of diabetes have increased the knowledge to such an extent that primary prevention of NIDDM is becoming a reality. This primary prevention can be implemented a) through a population strategy, i.e. changing the lifestyle and environmental determinants that are known to be risk factors for diabetes, and b) through high-risk strategy, i.e. targeting preventive measures only at those specific individuals or groups that are at high risk for the future development of NIDDM. The latter is the strategy of the Diabetes Prevention Program (DDP), a clinical study sponsored by the National Institute of Diabetes and Digestive and Kidney Disease in USA. Twenty five centers were selected to participate in this program. The purpose of DPP is prevent or delay the development of NIDDM in those persons who are at high risk because they have IGT. DPP will also evaluate if the interventions selected to prevent the development of NIDDM can decrease the frequency of cardiovascular events and the occurrence and magnitude of the cardiovascular risk factors that accompany NIDDM and IGT. Four thousand volunteers will be recruited from populations known to be at particular high risk fo IGT and NIDDM including the following: elderly, overweight individuals, persons with family history of NIDDM, women with history of gestational diabetes, and minority populations. In order to be eligible, persons who are older than 25 years will have to demonstrate IGT with plasma glucose levels 100-139 mg/dl fasting and 140-199 mg/dL two hours after a 75 g OGTT. Three study intervention were selected based on their potential efficacy in ameliorating abnormal glucose metabolism in IGT and on their safety and tolerable profile of side-effects. The interventions include: intensive lifestyle intervention which focuses on a healthy diet to achieve and maintain at least a 7% loss of body weight and an increase in caloric expenditure of at least 700 kcal per week. The drug therapy interventions include the biguanide metformin and the thiazolidinedione troglizatone. Standard life-style recommendations, which include conventional instructions regarding diet and exercise, will be provided to all participants, including a placebo treated group which will serve as the control group for the study. After randomization, participants will have quarterly evaluations and have, in addition, a fasting plasma glucose at semi-annual visits and a 75 g OGTT at annual visits. All participants will be followed for three years after the study-wide closing date for recruitment, resulting in 3 to 6 years of participant follow-up. The primary outcome is the development of NIDDM according to WHO criteria (fasting plasma glucose level 140 mg/dL or 2-hour plasma glucose 200 mg/dL after a 75 g OGTT). Secondary outcome will focus en cardiovascular disease and its risk factors and change of glycemia, insulin secretion and sensitivity, obesity, physical activity and nutrient intake, quality of life, and the occurrence of adverse events.
