12 #anth438 limitations:focus indiv 15-20yrs,not pregnant/lactational amenorrhea,unequal sample size btwn seasons, small overall sample size

[jjOrtiz @9caffe]

11.#anth438 considering growth velocity and mobilization of lean mass, may suggest ovarian function more robust than in faster growing women

[jjOrtiz @9caffe]

10.#anth438 results suggest shifts in priority of energy allocation occur progressively throughout puberty.things occur across continuum

[jjOrtiz @9caffe]

9.#anth438 important: there were no efforts made in energy conservation between seasons of energy abundance, could this produce an effect?

[jjOrtiz @9caffe]

8.#anth438 interesting: claim that chronological younger adolescents w/ higher growth velocity mobilize adipose tissues during hungry season

[jjOrtiz @9caffe]

7.#anth438 younger&chronological younger women w/higher heigh velocity preferentially acquired lean body mass in both seasons

[jjOrtiz @9caffe]

7.#anth438 adolescents who older&near end of linear growth lost lean body mass only during hungry season (gained during energy rich)

[jjOrtiz @9caffe]

6.#anth438 looking for variation btwn energy rich seasons(harvest season) and energy poor seasons(hungry season) for analysis 30 days

[jjOrtiz @9caffe]

5.#anth438 testing 67 adolescent females 14-19 in Keneba,Gambia. anthropometric measures (heigh/weight/skin thickness) and body comp tracked

[jjOrtiz @9caffe]

4.#anth438 purpose:What develop/chronological markers predict transition from preferred investment in growth to investment in reproduction?

[jjOrtiz @9caffe]

3. #anth438 investment in somatic growth (non reproductive investment) can be seen in growth of lean body mass in bones, muscles, and organs

[jjOrtiz @9caffe]

#anth438 in human females, repro function is reflected by ovarian hormone production converting energy into adipose tissues.

[jjOrtiz @9caffe]

#anth438 life history theory (LHT) says adolescence is period of shift of energy allocation from growth to repro. https://t.co/T36V1cTcUt

13. Mentioned group A mothers longer breastfeeding duration - did not elaborate more on implications. (potential ethical problem?) #anth438

[jjOrtiz @9caffe]

12. Interesting:2-week old bottle fed infants can't differentiate btwn mother milk odour and other female.But was bottle exclusive? #anth438

[jjOrtiz @9caffe]

11.Breastfeeding period of group A significantly longer that of group B. #anth438

[jjOrtiz @9caffe]

10.Results:regardless skin contact infants prefer mother milk odour vs unfamiliar lactating female.in utero genetic determination? #anth438

9. Follow up phone calls every 3 mo- still breastfeeding, level of breastfeeding, volume of formula if used, and infant development #anth438

[jjOrtiz @9caffe]

8.Observing and looking for behavioral mouthing patterns, suckling,licking,chewing during odour exposure #anth438
