Journal of the American Dietetic Association, June 1994, vol. 94, no. 6, pp. 641--644. [DM] "Is Obesity Hazardous to Your Health?" see Debates in Medicine, Yearbook medical publishers, 1989 vol. 2, pp. 102--137 [EH] P.Ernsberger & P.Haskew: "Health implications for obesity: An alternative view" Journal of Obesity and Weight Regulation, 1987, vol. 6, pp. 58--137 [Garn] S.M.Garn "Fractionating healthy weight" American Journal of Clinical Nutrition, March 1996 vol.63, no.3, Supplement pp. 412S--414S Discusses what a healthy weight is, considering the criteria used to define healthy, and that a weight advantageous for one respect may be disadvantageous for another. [GW] D.M.Garner & S.C.Wooley: "Confronting the Failure of Behavioral and Dietary Treatments for Obesity", Clinical Psychology Review, 1991, vol.11, pp. 729--780 Excellent long survey article, with many references to research on the subject. Points out that diets are mostly successful in the short term, but very ineffective in the long term. Instead recommendations are made for improving the lifestyle, health risk factors, body image and self-esteem of fat people without requiring weightloss. [Jhsn] F.E.Johnson: "Health Implications of Childhood Obesity" Annals of Internal Medicine, 1985, vol. 103, p1068 Just discusses the subject, with no stunning results. Remembers to mention the social and psychological implications. [Mall] M.J. Mallick: "Health Hazards of Obesity and Weight Control in Children: A Review of the Literature" American Journal of Public Health, 1983, vol. 73, pp. 78--82 -------------------------------------------------------------------- A2) Various Illnesses/Conditions and Fat People [Blo+] Bloom, Yano, Curb, Reed & MacLean: "Smoking cessation and incidence of coronary heart disease" CVD Epidemiology Newsletter (AHA), 1987, vol. 41, p. 36 [CS] "Gallstones." from Clinical Symposia, 1988, vol. 40, no. 2 [Des] J.P.Deslypere "Obesity and Cancer" Metabolism, Sept, 1995, vol. 44, no. 9, supp. 3, pp. 24--27 Obesity is a risk factor for some forms of cancer, but there are also other risk factors, such as distribution of fat, hormone levels (fat people have more estrogen), a high-fat low-fibre diet. They also take a look at the risk of breast cancer, and it's difficult to see if obesity plays a role as there are many other risk factors. Obese people get less lung cancer. [DGU] J.Dequeker, P.Goris and R.Uytterhoeven: "Osteoporosis and osteoarthritis (osteoarthrosis). Anthropometric distinctions" Journal of the American Medical Association, March 18th, 1983, vol. 249, no. 11, pp. 1448--1451 27 women with osteoporosis and 25 women with general arthritis were studied. The former were shorter, more slender and had less fat and muscle, whereas the latter were fatter with more muscle mass and strength. [Egu+] G.Egusa, W.F.Beltz, S.M.Grundy, B.V.Howard "Influence of obesity on the metabolism of apolipoprotein B in humans" The Journal of Clinical Investigation, August 1985, vol 76, no. 2, pp. 596--603 Does have some interesting individual statistics that show how much metabolism can vary from person to person. [EN] P.Ernsberger and D.O.Nelson: "Refeeding hypertension in dietary obesity" American Journal of Physiology, 1988, vol. 254, pp. R47--R55 [Fel+] Felman et al.: "Obesity and knee osteoarthritis: The Framingham Study" Annals of Internal Medicine, July 1st 1988, vol. 109, no. 1, pp. 18--24 The objective was to determine whether obesity is a possible cause for knee osteoarthritis. They found an increased risk for men in the heaviest quintile, and an increased risk for women in the heaviest and second-heaviest quintiles. They conclude that obesity or as yet unknown factors associated with obesity are risk factors for knee osteoarthritis. [GSH] S.M.Garn, T.V.Sullivan and V.M.Hawthorne "Effect of skinfold levels on lipids and blood pressure in younger and older adults" Journal of Gerontology, 1988, vol.43, no.6, pp. M170--4 They studied 5507 white participants, specifically looking at three groups: older adolescents, younger adults and older adults. In all three groups, they found that the fatter people (measured by skinfold measurements) had higher blood pressure levels (systolic and diastolic), and also higher in serum cholesterol and serum triglycerides. [HG] E.C. Hammond and L. Garfinkel: "Coronary heart disease, stroke, and anortic aneurysm: Factors in etiology" Archives of Environmental Health, vol. 19, pp. 167--182 [Keys] A.Keys: "Overweight, obesity, coronary heart disease, and mortality: the W.O. Atwater Memorial Lecture" Progress in Clinical Biology Research, 1981, vol. 67, pp. 31--46 [Lis+] Lissner, Odell, D'Agostino, et al: "Framingham Heart Study" New England Journal of Medicine, 1991, vol. 324, pp. 1839--1844 [Man+] Manson, Colditz, Stampfer, Willett, Rosner, Monson, Speizer & Hennekenes: "A prospective study of obesity and risk of coronary heart disease in women" New England Journal of Medicine, 1990, vol. 322, pp. 882--889 [PLKB] Pettitt et al.: "Mortality as a function of obesity and diabetes mellitus" American Journal of Epidemiology 1981, vol.115, no.3, pp. 359--366 2197 Pima Indians were studied. For men, they had the highest mortality risk at BMI more than 40, but BMI had no effect at lower BMIs; diabetes was not related to mortality. For women, death rates were not consistently related to fatness, although diabetics had a higher risk than non-diabetics. [RBSJ] E. Ravussin, B. Burnand, Y. Schutz, E. Jequier: "Twenty-four-hour energy expenditure and resting metabolic rate in obese, moderately obese, and control subjects" American Journal of Clinical Nutrition March 1982 vol. 35, no. 3, pp. 566--573 Examined 30 subjects either lean, moderately obese and obese, and compared resting metabolic rates and 24-hr energy expenditures. Obese people had higher resting rates and 24-hr energy expenditures. So large people don't just have a greater 24-hr EE just because they have to move more weight around, they use more energy when sitting still too, the study suggests this is due to more muscle in the obese. [RTP] C. Ribot, F. Tremollieres, J. M. Pouilles: "The effect of obesity on postmenopausal bone loss and the risk of osteoporosis" Advances in Nutritional Research, 1994, vol. 9, pp. 257--271 [Sto+] C. Stout et al,: "Unusually Low Incidence of Death from Myocardial Infarction..." Journal of the American Medical Association, 1964, vol. 188, pp. 845--849 [Su+] Su et al.: "Effect of weight loss on blood pressure and insulin resistance in normotensive and hypertensive obese individuals" American Journal of Hypertension, 1995, vol.8, no.11, pp. 1067--1071 22 people, 11 with high blood pressure were studied. Over 3 months both groups lost 8kg on average. Blood pressure and insulin resistance was lowered in both groups. [VVVV] J.L.van Saase, J.P.Vandenbroucke, L.k.van Romunde & H.A.Valkenburg "Osteoarthritis and obesity in the general population. A relationship calling for an explanation." Journal of Rheumatology, July 1988, vol. 15, no. 7, pp. 1152--1158 20 joints and groups of joints, weight-bearing and non-weight-bearing were investigated in 1071 men and 1097 women in the Netherlands. Osteoarthritis was positively associated with obesity in weight-bearing and non-weight-bearing joints. [WCBP] R.B.Wallace, C.Rost, L.F.Burmeister, P.R.Pomrehn "Cancer incidence in humans: relationship to plasma lipids and relative weight" Journal of the National Cancer Institute, 1982, vol.68, no.6, pp.915--918 Of a group of 5565 people in a cardiovascular screening program, 131 had cancer, and were matched individually to non-cancer people. The cancer patients had lower mean weight. -------------------------------------------------------------------- A3) Conception and Pregnancy in Fat Women [GSK] T.Gross, R.J.Sokol & K.C.King: "Obesity in pregnancy: risks and outcome" Obstetrics and Gynecology, October 1980, vol. 56, no. 4, pp. 446--450 This studied 2746 consecutive deliveries, 279 of whom were obese. Those in the obese group were at increased risk before birth (increased frequencies of chronic hypertension, inadequate pregnancy weight gain, twin gestation and diabetes mellitus). They also had slightly longer gestations. Infant outcome was similar for obese and non-obese mothers (similar Apgar scores and perinatal infant mortality). [IM+] Isaacs et al.: "Obstetric challenges of massive obesity complicating pregnancy" Journal of Perinatology, Jan-Feb 1994, vol. 14, no. 1, pp. 10--14 [LT+] Le Thai et al.: "Grossesse et obesite. A propos d'une etude cas-temoins de 140 cas (Pregnancy and obesity. A case control study of 140 cases)" Journal de Gynecologie, Obstetrique et Reproduction Biologique 1992, vol. 21, no. 5, pp. 563--567 [SVS] Gary M. Shaw, Ellen M. Velie, Donna Schaffer: "Risk of Neural Tube Defect-Affected Pregnancies Among Obese Women" Journal of the American Medical Association 1996, vol.275, pp. 1093--1096 [WLSM] Martha M. Werler, Carol Louik, Samuel Shapiro, Allen A. Mitchell: "Prepregnant Weight in Relation to Risk of Neural Tube Defects" Journal of the American Medical Association 1996, vol.275, pp. 1089--1092 [Zaa+] B.M.Zaadstra et al. "Fat and female fecundity: prospective study of effect of body fat distribution on conception rates", British Medical Journal, February 1993, vol. 306, no. 6876, pp. 484--7 542 women were studied at a fertility clinic in the Netherlands. They found that a larger waist-hip ratio led to a decrease in fertility. Also they found that underweight women were slightly slower to conceive than average weight women. Obese women were as fast to conceive as average weight women, but the conception rate was noticeably reduced for very obese women (BMI > 38), lower than the underweight group. They concluded than body fat distribution had more impact on fertility than age or obesity. -------------------------------------------------------------------- A4) Causes of Obesity [BYD] G.A.Bray, B.York, J.Delany "A survey of the opinions of obesity experts on the causes and treatment of obesity" American Journal of Clinical Nutrition, January 1992, vol 55 (Supp 1), pp. 151S--154S They surveyed opinions of 50 obesity researchers, from Europe and North America. Overall, genetic factors were considered to be the most important cause of obesity. The women tended to view lack of physical activity, carbohyrate cravings and weight cycling as more significant than the men did. Opinions as to treatments varied. Women preferred exercise more highly; older researchers preferred low fat diets more highly. All thought that serotonergic and thermogenic drugs were effective, and that their usefulness would increase over the next decade. [Borj] M.Borjeson: "The etiology of obesity in children" Acta Pediatrica Scandinavia, 1976, vol. 65, 279--287 [Pri+] R.A.Price, R.J.Cadoret, A.J.Stunkard, E.Troughton: "Genetic contributions to human fatness: An adoption study" American Journal of Psychiatry, 1987, vol. 144, pp. 1003--1008 [St+1] A.J.Stunkard et al.: "An Adoption Study of Human Obesity", New England Journal of Medicine, 1986, vol. 314, pp. 193--198 [St+2] A.J.Stunkard et al.,: "A Twin study of Human Obesity", Journal of the American Medical Association, July 1986, vol. 256, pp. 51--54 [SHPM] A.J.Stunkard & J.R.Harris & N.L.Pederson & G.E.McClearn: "The body-mass index of twins who have been reared apart", New England Journal of Medicine, vol. 322, 1483--1487 They point out that it is known there is a genetic contribution (studies of twins and adoptees/biological parents show correlations, but not adoptees/adopting parents) but the question is how much. They studied 93 identical twins raised apart, 154 identical twins raised together, 218 fraternal twins raised apart and 208 fraternal twins raised together (Swedish twins), and for the identical twins raised apart, the intra-pair correlation coefficient was 0.70 for men, 0.66 for women. They conclude the genetic contribution is substantial. -------------------------------------------------------------------- A5) Life Expectancy of Fat People [Bla+] Blair, Kohl, Paffenbarger, Clark, Cooper & Gibbons: "Physical Fitness and All-Cause Mortality. A Prospective Study of Healthy Men and Women" Journal of the American Medical Association, 1989, vol. 262, pp. 2395--2401 10224 men and 3120 women were studied. Fitness was measured by a treadmill, and average follow-up was 8 years per person. The study looks as various factors such as cholesterol, systolic blood pressure, BMI. Results show that low fitness is a big risk factor for men and women. Tables looking at BMI, fitness and mortality rates show for both men and women the highest risk amonst thin unfit people. Those with BMI below 20 had a higher mortality risk, where as BMI 20-25 had a similar risk to those with BMI > 25. Fitness consistently reduced mortality risk regardless of age or gender or BMI. [DBSJ] E.J.Drenick, G.S.Bale, F.Seltzer and D.G.Johnson: "Excessive Mortality and Causes of Death in Morbidly Obese Men" Journal of the American Medical Association, 1980, vol. 243, pp. 443--445 See the review in section A8. [GHPP] S.M.Garn, V.M.Hawthorne, J.J.Pilkington and S.D.Pesick "Fatness and mortality in the West of Scotland" American Journal of Clinical Nutrition, August 1983 vol.38, no.2, pp. 313--319 The researchers studied mortality data over 16 years, for men aged 45 to 75, from the West of Scotland. The lean had a higher mortality rate than the obese. Obese men tended to show more deaths due to heart problems, and lean men tended to show more deaths due to cancer. The adverse effects of smoking were also clearly seen here. [Keys] A.Keys: "Overweight, obesity, coronary heart disease, and mortality: the W.O. Atwater Memorial Lecture" Progress in Clinical Biology Research, 1981, vol. 67, pp. 31--46 [LP] I.Lee and R.S.Paffenberger: "Change in Body Weight and Longevity" Journal of the American Medical Association, 1992, vol. 268, pp.2045--2049 [Man+] J.E.Manson, W.C.Willet, M.J.Stampfer, G.A.Colditz, D.J.Hunter, S.E.Hawlinson, C.H.Hennekens, F.E.Speizer: "Body Weight and Mortality Among Women" New England Journal of Medicine, 1995, September 14th They studied 115,195 women nurses, aged 30-55 years, from 1976 to 1992, all of whom were free of cardiovascular disease and cancer in 1976. A J-shaped curve of relative risk vs. BMI was obtained, which was more /-shaped if smokers were factored out. Figures for fat people consistent with other research, also with J-shaped curves. Sample result: Age-adjusted relative risk (AARR) for BMI below 19.0 was 1.0, compared to AARR for BMI 25.9 was 0.7, compared to AARR for BMI 35.8 was 1.3. When smokers were factored out the AARRs were 1.0 for BMI below 19.0, 1.1 for BMI 25.9 and 1.9 for BMI 35.8. The actual order of magnitude of the risks were in the range 1 to 4 per 1000 (per person-year). [Sor+] P.Sorlie, T.Gordon & W.B.Kannel: "Body build and mortality: The Framingham study" Journal of the American Medical Association, 1980, vol. 243, pp. 1828--1831 [Wil+] T.Wilcosky, J.Hyde, J.J.B.Anderson, S.Bangdiwala and B.Duncan: "Obesity and mortality in the lipid research clinics program follow-up study" Journal of Clinical Epidemiology, 1990, vol.43, pp. 743--752 -------------------------------------------------------------------- A6) Fatness and Fitness [Bjo+] P. Bjorntorp et al.: "Physical training in human obesity. 3. Effects of long-term physical training on body composition" Metabolism, 1973, vol. 22, no. 12, pp. 1467--1475 [Bla+] Blair, Kohl, Paffenbarger, Clark, Cooper & Gibbons: "Physical Fitness and All-Cause Mortality. A Prospective Study of Healthy Men and Women" Journal of the American Medical Association, 1989, vol. 262, pp. 2395--2401 [KDSA] T.A.Kaplan, S.L.Digel, V.A.Scavo, S.B.Arellana: "Effect of obesity on injury risk in high school football players" Clinical Journal of Sports Medicine 1995, vol. 5, no. 1, pp. 43--47 98 high school football players were studied. The fat players showed a similar risk of injury to the thin players, but the heavy players (over 90 kg) showed a 2.5 greater risk of injury than the light players. [KB] M. Krotkiewski & P. Bjorntorp: "Muscle Tissue in Obesity with Different Distribution of Adipose Tissue. Effects of physical Training" International Journal of Obesity, 1986, vol.10, pp. 331--341 [Kro+] M.Krotkiewski et al: "Effects of long-term physical training on bodyfat, metabolism, and blood pressure in Obesity" Metabolism, 1979, vol. 28, p650 They physically trained 27 women with varying degrees of obesity for 6 months on an ad lib diet. They found that obese women with fewer fat cells lost weight, whereas women with severe obesity and more fat cells even gained weight. Blood pressure consistently decreased. [KBVA] N. L. Keim et al.: "Energy expenditure and physical performance in overweight women: response to training with and without caloric restriction" Metabolism, June 1990, vl. 39, no. 6, pp. 651--658 Notes various statistics for 10 women (big study data, eh?) of above average size but not huge, on a 14 week study. Half took exercise only, half took exercise and diet restriction. The study notes various body composition and VO2 statistics, and concludes that the diet+exercise combination resulted in more fat-loss. [Ok] K. Okada: "Effects of long-term corporate fitness program on employees' health" Journal of Nutr. Sci. Vitaminol Tokyo, December 1991, Suppl. 37, S131-8 The purpose of this study was to assess the affects of a long-term corporate fitness program. 1499 male employees had medical checkups, physical fitness tests and physical training. Results included that the proportion of obese workers showed no change; physical fitness was noticeably improved; there was a decrease in the percentage of smokers; there were no significant changes in total cholesterol levels nor in incidences of hypertriglyceridemia or hypercholestrolemia. [SS] K. R. Segal & F. X. Pi Sunyer "Exercise and Obesity" Med. Clin. North American. January 1989, vol. 73, no. 1, pp. 217--236 They suggest it is unlikely that resting metabolism is altered by exercise, either long-term or acutely (and go on to suggest a combination of caloric restriction and physical training for fat loss). -------------------------------------------------------------------- A7) Social Aspects of Fatness [Cra1] C.S.Crandall: "Do heavyweight students have more difficulty paying for college?", Personality and Social Psychology Bulletin, 1991, vol. 17, pp. 606--611 Hint: The answer is yes. [Cra2] C.S.Crandall: "Prejudice against fat people: Ideology and self-interest" Personality and Social Psychology, 1994, vol.66, pp. 882--894 Anti-fat prejudice is closely linked to various beliefs about the world--that things are controllable, conservative politics, belief in a just world, protestant ethic, and other traditional values. [Cra3] C.S.Crandall: "Do parents discriminate against their own heavyweight daughters?", Personality and Social Psychology Bulletin, 1995, vol. 21, pp. 724--735 Surprisingly, yes. Furthermore, parents who endorse traditional conservative values appear to be more likely to discriminate against their own daughters. [C+M] C.S.Crandall, R.Martinez: "Culture, ideology, and anti-fat attitudes" Personality and Social Psychology Bulletin, 1996, vol. 22, pp. 1165--1176 Mexico is less anti-fat than the USA, and women there are less concerned about their own weight than women in the USA. In addition, anti-fat prejudice is not linked to social ideology and conservative values in Mexico as it is in the USA. [Gor+] Gortmaker, Aviva, Perrin, Sobol, Dietz: "Social and Economic consequences of Overweight in Adolescence and Young Adulthood", New England Journal of Medicine, 1993, pp. 1008--1012 [JP] Craig R. Janes & Ivan G. Pawson: "Migration and biocultural adaptaion: Samoans in California" Social Science & Medicine, 1986, vol. 22, no. 8, pp. 821--834 [FB] M.A.Freidman and K.D.Bromwell: "Psychological Correlates of Obesity: Moving to the Next Research Generation" Psychological Bulletin, vol. 117, pp. 3--20 [Go+] S.L.Gortmaker et al.: New England Journal of Medicine, 1983, vol. 329, pp. 1008--1012 [Ros] James Rosen et al.: "Cognitive Behavior Therapy for Negative Body Image in Obese Women" Behaviour Therapy, Jan-Feb-Mar 1995 [Roth] E. Rothblum: "I'll die for the revolution but don't ask me not to diet: feminism and the continuing stigmatization of obesity" Feminist Perspectives on Eating Disorders, Guildford Press, 1994, pp. 53--76 [SK] S. M. Shaw and L. Kemeny: "Fitness promotion for adolescent girls: the impact and effectivenes of promotional material which emphasizes the slim ideal" Adolescence, Fall 1989, vol. 24, no. 95, pp. 677--687 This studied techniques for promoting fitness participation amongst teenage girls. Posters used different models (slim,average,large) and different messages (slim,active,health) and the slim model was the most effective poster, whereas the slim message was the least effective message. The data indicates that promoting fitness through messages relating slimness to fitness isn't effective, and they point out that using very slim models may not be desirable because it reinforces the slim stereotype. [SS] Stunkard and Sorensen: "Obesity and Socioeconomic Status--A Complex Relation" Editorial in New England Journal of Medicine, 1993, vol. 324, pp. 1036--1037 [WW1] Susan C. Wooley & Orland W.

Dyrenforth: "Theoretical, Practical, and Social Issues in Behavioral Treatments of Obesity", Journal of Applied Behaviour Analysis, 1979, vol. 12, pp. 3--25 -------------------------------------------------------------------- A8) Weight Change in Fat People [AK] Ashley & Kannel: "Relation of weight change to changes in atherogenic traits: The Framingham Study" Journal of Chronic Diseases, 1974, vol. 27, pp. 103--114 [DBSJ] E.J.Drenick, G.S.Bale, F.Seltzer and D.G.Johnson: "Excessive Mortality and Causes of Death in Morbidly Obese Men" Journal of the American Medical Association, 1980, vol. 243, pp. 443--445 Results from a study of 200 obese men who checked into a diet clinic and followed the program for two years. Most regained the weight, there was a twelve-fold increase in deaths compared to average men in the 25-34 age group, and a six-fold corresponding increase in the 35-44 group. More deaths were due to cardiovascular disease, and less due to malignancies. They admit the study is statistically not significant, but think the results interesting. I quote: "It appears that no unusual factors other than obesity could have caused such extraordinary mortality", when it is obvious that the men also had the two-year diet in common. No details were given about the diet. Dr.Drenick and Ms.Johnson were from the Veterans Administration, Dr. Bale and Mr. Seltzer from the Metropolitan Life Insurance Company. [EK] Ernsberger & Koletsky: "Weight Cycling and Mortality: Support from Animal Studies" Journal of the American Medical Association, vol. 269, pp. 1116--1993 In this short letter to the JAMA, they point out that [LP] shows that weight fluctuations increase mortality by over 50%, which overshadows the 18% rise in mortality associated with the 20% fattest people. They also quote results from animal research which supports their view that there's a growing hypothesis that weight loss and regain is harmful. [GMS] C.A.Geissler, D.S.Miller, M.Shah: "The daily metabolic rate of the post-obese and the lean" American Journal of Clinical Nutrition, May 1987, vol. 54, no. 5, pp. 914--920 The study took 16 post-obese women and matched them for age, weight, height and other factors with 16 naturally lean women. The post-obese women had metabolic rates approximately 15% lower than the naturally lean women, and also ate less. [Ha+] P.Hamm, R.B.Shekelle & J.Stamler: "Large fluctuations in body weight during young adulthood and twenty-five year risk of coronary death in men."

They all found it difficult to gain the weight, although all but a few managed to reach the target. The typical prisoner was needing to eat 7000 calories per day to gain the weight, although the top end of the range was 10000 calories to sustain weight. They lost the weight relatively easily, returning to (typically) 2 or 3 kg above previous weight. [SMG] M. Shah, D. S. Miller, C. A.

The mean metabolic rate of the post-obese was 15% lower than that of the naturally thin women. -------------------------------------------------------------------- A9) Eating Disorders and Obesity [HP] C.
