Narrative:

Advised by flight attendant of fumes in the cabin. I asked two flight attendants to come to the cockpit for more detailed information. All four flight attendants were experiencing the fumes as well as a couple of passengers. The fumes were reported strong in the aft cabin and weak in the forward cabin. No noticeable odors in the cockpit. The fumes were bad enough for at least two of the flight attendants to use supplemental oxygen. This event occurred on climbout out at approximately 6;000 feet. I leveled off at 14;000 feet to access the situation and decided to return. No emergency was declared. The odor remained throughout the divert back where the passengers were deplaned. Landing [was] uneventful. Paramedics took vital signs of 5 of the 6 crewmembers; some of who were experiencing different symptoms. A fumes/odor maintenance form was completed by the captain.the APU was off. Only the engines were running. There were two maintenance issues resolved away from the gate and prior to takeoff. First issue was an autoflight yaw dampner number 1 and the second item was an inoperative autopilot. If there could be a connection with the hydraulic system; I do not know. I was informed that the aircraft had no prior history of fume events.
