Comparative analysis of trends and determinants of anaemia between adult and teenage pregnant women in two rural districts of Ghana

Table 2 Hb levels per age group at ANC registration and at the 36th week of gestation

Groups		Mean	N	Std. Deviation	Mean difference within group	P value	Within group correlation coefficient	P value
Combined group (Teenage+ Adult)	Hb at registration	10.20	231	1.8	0.26	0.070	0.22	0.001
	Hb at 36th week	10.50	231	1.7
Teenage	Hb at registration*	10.03	24	2.0	0.46	0.376	0.42	0.039
	Hb at 36th week^	10.50	24	2.5
Adult	Hb at registration*	10.30	207	1.8	0.23	0.123	0.18	0.001
	Hb at 36th week^	10.55	207	1.6

*p-value- analysis of the mean difference between teenage only and adult only groups for Hb levels at antenatal registration = 0.028
^p-value- analysis of the mean difference between teenage only and adult only groups for Hb levels at the 36th week of gestation = 0.893
No mean difference was found between teenagers and adults at ANC registration and at the 36th week of gestation, when combined and analysed separately. A significant difference was found between the Hb levels of teenagers and adults at ANC registration. Further analysis of the correlation between Hb levels at ANC registration and the 36th week of gestation showed a weak but positive correlation in both teenagers and adults, when analysed together and separately.
