Int J Behav Nutr Phys Act. 2011 Aug 17;8(1):89

Abstract

Background: Behavioral mechanisms that contribute to the association between breastfeeding and reduced obesity risk are poorly understood. The purpose of this study was to evaluate the hypothesis that feeding human milk from the breast (direct breastfeeding) has a more optimal association with subsequent child appetite regulation behaviors and growth than bottle-feeding.

Chronic disease and infant nutrition: is it significant to public health?

Smith JP, Harvey PJ.
Public Health Nutr. 2010 Jul 13:1-11.

Abstract

OBJECTIVE: To assess the public health significance of premature weaning of infants from breast milk on later-life risk of chronic illness.

Do Infants Fed From Bottles Lack Self-regulation of Milk Intake Compared With Directly Breastfed Infants?

Li R, Fein SB, Grummer-Strawn LM.
Pediatrics. 2010 Jun;125(6):e1386-93.

Abstract

OBJECTIVE: How breastfeeding reduces the risk of childhood obesity is unclear, and 1 hypothesis pertains to the ability of breastfed infants to self-regulate. We studied whether infants' self-regulation of milk intake is affected by feeding mode (bottle versus breast) and the type of milk in the bottle (formula versus expressed breast milk).

Body mass index, adiposity rebound and early feeding in a longitudinal cohort (Raine Study).

Chivers P, Hands B, Parker H, Bulsara M, Beilin LJ, Kendall GE, Oddy WH.
Int J Obes (Lond). 2010 Mar 30. [Epub ahead of print]

Abstract

Objective: This study examined the influence of type and duration of infant feeding on adiposity rebound and the tracking of body mass index (BMI) from birth to 14 years of age.

Characteristics and potential functions of human milk adiponectin

Newburg DS, Woo JG, Morrow AL.
J Pediatr. 2010 Feb;156(2 Suppl):S41-6.

Abstract

Adiponectin is a protein hormone produced by adipose tissue, whose circulating levels are inversely related to adiposity and inflammation. Adiponectin circulates as oligomers, from the low-molecular-weight trimer to the high-molecular-weight octodecamer (18 mer). Each oligomer has distinct biological activities, which include enhancement of insulin sensitivity and metabolic control and suppression of inflammation. Adiponectin occurs in human milk at higher concentrations than leptin.

Human milk adiponectin is associated with infant growth in two independent cohorts

Woo JG, Guerrero ML, Altaye M, Ruiz-Palacios GM, Martin LJ, Dubert-Ferrandon A, Newburg DS, Morrow AL.
Breastfeed Med. 2009 Jun;4(2):101-9.

Abstract

BACKGROUND: Adiponectin, a circulating adipocyte protein, is associated with lower obesity. We have previously shown that adiponectin is present in human milk. This study determined whether higher milk adiponectin is associated with infant growth and investigated milk adiponectin's oligomeric form.

Breastfeeding reduces postpartum weight retention

Jennifer L Baker, Michael Gamborg, Berit L Heitmann, Lauren Lissner, Thorkild IA Sørensen and Kathleen M Rasmussen

American Journal of Clinical Nutrition, Vol. 88, No. 6, 1543-1551, December 2008

Abstract

Background: Weight gained during pregnancy and not lost postpartum may contribute to obesity in women of childbearing age.

Objective: We aimed to determine whether breastfeeding reduces postpartum weight retention (PPWR) in a population among which full breastfeeding is common and breastfeeding duration is long.

Duration of lactation is associated with lower prevalence of the metabolic syndrome in midlife

Kavitha T. Ram, Paul Bobby, Susan M. Hailpern, Joan C. Lo, Miriam Schocken, Joan Skurnick, Nanette Santoro

American Journal of Obstetrics & Gynecology 2008; 198:3 268.e1-e6

Abstract

Objective
The objective of the study was to evaluate whether lactation duration is associated with lower prevalence of metabolic syndrome (MetSyn) in midlife, parous women.

Breastfeeding helps explain racial and socioeconomic status disparities in adolescent adiposity

Woo JG, Dolan LM, Morrow AL, Geraghty SR, Goodman E.
Pediatrics. 2008 Mar;121(3):e458-65.

Abstract

OBJECTIVES: Studies suggest that breastfeeding is protective for later obesity; however, this association has not held among all racial and socioeconomic status groups. Racial and socioeconomic status differences in breastfeeding behavior have also been noted. In this study, we formally test whether breastfeeding mediates the relationship between race and socioeconomic status with adolescent adiposity.

Breastfeeding and Maternal and Infant Health Outcomes in Developed Countries

Stanley Ip, M.D., Mei Chung, M.P.H., Gowri Raman, M.D., Priscilla Chew, M.P.H., Nombulelo Magula, M.D., Deirdre DeVine, M.Litt., Thomas Trikalinos, M.D., Ph.D., Joseph Lau, M.D.

Agency for Healthcare Research and Quality, U.S. Department of Health and Human Services, April 2007

Structured Abstract

Objectives: We reviewed the evidence on the effects of breastfeeding on short- and long-term infant and maternal health outcomes in developed countries.

Data Sources: We searched MEDLINE®, CINAHL, and the Cochrane Library in November of 2005. Supplemental searches on selected outcomes were searched through May of 2006. We also identified additional studies in bibliographies of selected reviews and by suggestions from technical experts.

Számít-e az anyai cukorbetegség vagy az anyai elhízás?

Bevezetés

Az utóbbi időben készült meta-analízisek azt találták, hogy a szoptatás mintegy 13-22%-kal csökkenti a gyermekkori vagy a későbbi elhízás kockázatát. Harder és munkatársainak meta-analízise ezen felül megállapította, hogy a hatás dózisfüggő: minél tovább tart a szoptatás, annál kifejezettebb. A hatás alapja lehet, hogy a szoptatás esetében az anya a csecsemő igényeit veszi figyelembe az etetéskor, míg a mesterséges táplálás során az anya dönti el, hogy mennyi táplálékot fogyaszt a kisbaba. Az is lehetséges, hogy a kisbaba élettani reakciója az anyatejben lévő tápanyagokra és hormonokra a magyarázata a szoptatás növekedésre gyakorolt hatásának.

A kutatás célja: annak vizsgálata, hogy az anyai cukorbetegség ill. elhízás gyengíti-e a szoptatás már korábban kimutatott jótékony hatásait a gyermekkori elhízással kapcsolatban.

Evidence on the long-term effects of breastfeeding: systematic review and meta-analyses

Bernardo L. Horta, Rajiv Bahl, José C. Martines, Cesar G. Victora
World Health Organization 2007

Executive summary

Background: Breastfeeding presents clear short-term benefits for child health, mainly protection against morbidity and mortality from infectious diseases. On the other hand, there is some controversy on the long-term consequences of breastfeeding. Whereas some studies reported that breastfed subjects present a higher level of school achievement and performance in intelligence
tests, as well as lower blood pressure, lower total cholesterol and a lower prevalence of overweight
and obesity, others have failed to detect such associations.

Duration of breastfeeding and risk of overweight in childhood: a prospective birth cohort study from Germany

M Weyermann, D Rothenbacher and H Brenner

International Journal of Obesity (2006) 30, 1281–1287

Abstract

Background:
Whereas a recently published meta-analysis showed that ever breastfeeding reduces the risk of obesity in childhood significantly, the recent literature describing the relationship between duration of breastfeeding and risk of overweight or obesity in childhood remains inconclusive.
