在近日的PLoS ONE上刊登了一項研究稱，英國研究人員發(fā)現,，靠配方奶粉喂養(yǎng)的嬰兒比較不愛哭,，也比較好哄，但長大后也更容易超重,。
來自劍橋大學的研究人員日前研究了300個英國嬰兒的行為,。觀察發(fā)現，吃配方奶粉的孩子比較容易滿足,，吃母乳的孩子比較愛哭,，不容易入睡。
研究人員解釋,，靠奶粉喂養(yǎng)的孩子每次都能吃飽,，不會有不夠吃的情況出現，于是這些嬰兒就養(yǎng)成了靠吃來獲得滿足的習慣,，但長大后也更容易肥胖,。而吃母乳的孩子愛哭鬧是因為他們希望媽媽在身邊陪伴，也是正常的行為,，母親不應因此放棄母乳喂養(yǎng),。(生物谷 Bioon.com)

Background & Methods
To examine the relationship between breastfeeding and maternally-rated infant temperament at age 3 months, 316 infants in the prospective Cambridge Baby Growth Study, UK had infant temperament assessed at age 3 months by mothers using the Revised Infant Behavior Questionnaire, which produces scores for three main dimensions of temperament derived from 14 subscales. Infant temperament scores were related to mode of infant milk feeding at age 3 months (breast only; formula milk only; or mixed) with adjustment for infant's age at assessment and an index of deprivation.
Results
Infant temperament dimension scores differed across the three infant feeding groups, but appeared to be comparable between exclusive breast-fed and mixed-fed infants. Compared to formula milk-fed infants, exclusive breast-fed and mixed-fed infants were rated as having lower impulsivity and positive responses to stimulation (adjusted mean [95% CI] “Surgency/Extraversion” in formula-fed vs. mixed-fed vs. breast-fed groups: 4.3 [4.2–4.5] vs. 4.0 [3.8–4.1] vs. 4.0 [3.9–4.1]; p-heterogeneity = 0.0006), lower ability to regulate their own emotions (“Orienting/Regulation”: 5.1 [5.0–5.2], vs. 4.9 [4.8–5.1] vs. 4.9 [4.8–5.0]; p = 0.01), and higher emotional instability (“Negative affectivity”: 2.8 [2.6–2.9] vs. 3.0 [2.8–3.1] vs. 3.0 [2.9–3.1]; p = 0.03).
Conclusions
Breast and mixed-fed infants were rated by their mothers as having more challenging temperaments in all three dimensions; particular subscales included greater distress, less smiling, laughing, and vocalisation, and lower soothability. Increased awareness of the behavioural dynamics of breastfeeding, a better expectation of normal infant temperament and support to cope with difficult infant temperament could potentially help to promote successful breastfeeding.
